Conclusion 

The market is trending towards low-cost, highly functional, fully integrated IoT devices. To stay competitive, adopting Rigid HDI PCBs will help improve your IoT product design, increase reliability, and improve the time to market.

Over the past few years, printed circuit board technology has advanced dramatically. It demands goods that are both faster and more compact. HDI boards are considerably smaller now. They have tiny pads, copper traces, ultra-fine vias, and gaps.

HDI-printed circuit boards have significantly higher wiring density per unit than traditional printed circuit boards. HDI PCBs are typically defined as printed circuit boards with micro vias, blind vias, buried vias, high signal functionality, and built-up laminations.

Thus, high-density layouts have denser wiring, resulting in lighter weight, fewer layers, and more condensed PCBs. Instead of using multiple PCBs in a device, a single HDI board is adequate to house the functionality of the prior boards.

• Finer lines and spaces < 100 um / 0.01 mm
• Smaller vias<150 um and capture pads <400 um / 0.40mm
• Higher connection pad density > 20 pads/cm2
• 120-160 average pins per square inch

Benefits of Rigid HDI PCB Substrates:

• Better electrical performance and signal integrity
• Lower noise and crosstalk, and lower EMI/RFI
• Smaller size and weight
• Cost optimization
• Reduced design time
• More reliable designs
• Complex and dense devices
• Compact PCBs

When designing an HDI PCB board, it is critical to keep important manufacturing and design challenges in mind. There are a few of the most commonly reported difficulties:

• More connections are required to finish the board.
• You must design smaller parts in a much narrower space.
• There are relatively few workplace areas.
• There is a restricted board workstation area.
• There are more parts on each side of the PCB layer.

Types of Rigid HDI PCB Substrates:

A via is a tiny conductive hole that connects multiple layers of a PCB with a high density of interconnectivity. It provides signs so that one can pass across them with ease. Four different kinds of through holes penetrate into an HDI PCB, all of which are subject to PCB operations.
These are the following:

Blind Vias

To link the center layer of a multi-layered HDI PCB to the periphery, a drill or laser is used to punch the hole. The reason this hole is called the blind via is because it is only visible from one side of the PCB board. But keep in mind that this kind of hole is expensive and difficult.

Buried-vias

The multiplayer HDI PCB’s two inner layers are connected via the buried vias. It gets its name since it is always located on the internal surface of the printed electronics board and is invisible from the outside. A different drill file is needed for this via since it is also a plated hole. A buried passage has an even number of layers, such as 2, 4, 6, 8, and so forth.

Micro-vias 

The micro vias, as their name suggests, are the smallest form, measuring less than 150 microns in diameter. A laser is also used to puncture it. These are among the most common kinds of vias used in HDI PCBs to connect one layer to the one next to it. In addition, its diameter is much smaller than that of mechanically bored vias, such as the through-hole. They are able to manufacture boards for electronics with more complex designs that are denser because of their size and ability to connect layers.

Via-holes

A drill or laser is used to drill this hole from top to bottom across the PCB. It facilitates the connection of the multi-layer PCB’s layers. Not only are they easy to build, but they are also among the most cost-effective options. To make them more inclusive, they have been separated into non-plated-through and plated-through holes.

Compared to microvias and through-hole vias, HDI technology offers a number of benefits, which include:

• Improved consistency: Compared to traditional PCBs, HDI PCBs are more trustworthy and less prone to damage since they contain fewer features and more densely packed interconnections.

• Improved performance: HDI PCBs are compatible for faster signal transfer, feature a greater number of connections, and provide improved performance for electrical devices.
• Higher densities of interconnections are supported by HDI technology, meaning that more superior connections can be constructed in a smaller space. It is essential for producing smaller and more complex PCBs.

HDI PCBs Structures:

HDI PCB (1+N+1): Simplest HDI

• One “build-up” of high-density connector layers makes up this HDI PCB structure, making it appropriate for BGAs with fewer I/O counts.

• • It features great mounting stability and dependability, fine lines, registration technologies with a 0.4 mm ball pitch, microvia, and the potential for copper filled via.
• Applications: GPS, memory card, MP3 player, and cell phone.

HDI PCB (2+N+2): Moderate Complex HDI

• Two or more “build-up” of high-density connection layers make up the HDI PCB structure; microvias on various levels can be stacked or staggered; Copper-filled layered micro via structures are frequently found in difficult designs with demanding specifications for high-performance signal transmission. 
• These can be utilized to boost routing density in a complex design while keeping a thin final board thickness; they are appropriate for the BGA with smaller ball pitch and greater I/O counts.
• Applications include game consoles, PDAs, cell phones, and portable video recorders.

ELIC (Every Layer Interconnection): Most Complex HDI

• • All of the layers in this high-density interconnection (HDI) PCB topology enable free connectivity of conductors on any layer via copper-filled stacking microvia structures. 
  • This produces improved electrical characteristics and offers a dependable connectivity solution for extremely complicated big pin-count gadgets, such as CPU and GPU processors used in portable and mobile devices. 
• Applications include memory cards, MP3, GPS, cell phones, ultra-mobile PCs, and compact computers.

PCBs are made up of two main components: printed wires (the copper traces) and a substrate, or the board.
Substrates that divide the different layers are needed for multi-layer boards. The substrate acts as both an electrical insulator between conductive portions and a structural support for the printed wires and circuit components.

PCB substrates are incapable of conducting electric currents. They act as a layered electrical insulator between electronics for this reason. A material that does not conduct when subjected to an electrical current is known as an electrical insulator because its internal electric charge does not flow freely. As a result, plated through holes are used to connect traces on opposing levels in every layer of the circuitry.

Purpose of PCB Substrate

A printed circuit board is constructed using substrate as a base. A PCB’s electrical, thermal, and physical characteristics are determined by its substrate. Typically, substrates are dielectric composite structures made of epoxy resin combined with one or both sides connected with copper foil. The copper layer is then covered with a solder mask to shield it from other elements that can damage the copper traces.

In multi-layer PCB, the laminate core is press between the substrate and all of the layers are bonded together with prepregs by applying high pressure and high temperature.

A PCB’s hard substrate enhances its strength and durability, whereas flexible substrates enable the construction of flexible circuits that may be bent and twisted without impairing signal flow. A PCB’s substrate determines its physical qualities.

Types of Multilayer Rigid PCBs Substrates

There are five different types of multilayer rigid PCBs substrates, each with special qualities for use in particular applications. 

FR-2

This lower-grade substrate is composed of easily machined impregnated paper, sometimes known as phenolic, over a fiberglass substrate. Flame Resistant is what the name “FR” stands for. Typically, less priced consumer gadgets use this kind of substrate.

FR-4

Fiberglass substrates consist of a flame-resistant substance that has been impregnated into woven fiberglass. Although the material is stiff and can be drilled, cut, or machined, tungsten carbide tools are required since the fiberglass is abrasive. In comparison to a FR-2, a FR-4 substrate is stronger and more resistant to breaking or shattering and are typically found in more expensive devices.

RF (High frequency)

RF substrates are used in printed circuit boards for high power radio frequency applications. They are made of low dielectric polymers. The substrate exhibits remarkable electrical performance properties despite its weak mechanical attributes.

A dielectric is inserted between a copper layer and a sub-composite that has already undergone lamination as part of the sequential lamination process.

Sequential lamination can be used to incorporate buried and blind vias into a PCB. A PCB with buried vias is produced by first creating a layer with blind vias (as though it were a two-sided PCB) and then consecutively laminating this layer with an inner layer.

HDI boards go through this process more than once when varying via structure types and layer combinations are required.

PCB runner has the capability of following material for multilayer PCB substrates:

Thermal Benefits of PCB substrates
The electrical and thermal properties of PCB substrates:

A printed circuit board’s electrical and thermal conductivity are also determined by its substrate.

Important Thermal Characteristics:

The temperature at which a substrate material changes from a stiff to a soft state—or, to put it another way, melts—is known as the glass transition temperature (Tg). PCB boards should never run over the substrate’s glass transition temperature.
The temperature at which the PCB substrate material undergoes chemical breakdown is known as the decomposition temperature (Td).

Coefficient of Thermal Expansion (CTE):

CTE is a measurement of how quickly a material expands in the presence of heat. The enlargement will result in a size rise that could potentially cause internal stress and harm. To find out more about CTE, go here.

The rate at which a material conducts heat is determined by its thermal conductivity or k.

How Thermal Conductivity Affects PCB Temperature?

One of the many crucial elements of PCB design is selecting a substrate with an appropriate thermal conductivity. Smaller boards with fast-switching active components are more likely to require thermal management in PCBs, as are boards carrying high currents because resistive losses in a trace cause heat to be generated, which then transfers into the substrate.

It can be necessary to select a substrate with increased thermal conductivity if there is a likelihood that the board will produce a lot of heat while operating or if it will be used in a hot environment. Maintaining the temperature of crucial components within their acceptable operating range may also require the use of passive cooling, active cooling, or both.

Evaluating Other Material Properties and Thermal Conductivity

Strong heat conductivity PCB substrate materials are known to have strong electrical conductivity as well. This does not imply that the substrate’s actual part of the dielectric constant will likewise increase in value. Instead, it indicates that higher thermal conductivity substrates typically have larger conductive losses in their substance.

This indicates that heat at the trace’s surface and leakage between the transmission line and its reference conductor will cause losses along a transmission line in a PCB to grow. 

Volumetric expansion of Multilayer rigid PCBs substrates

The volumetric expansion of PCB substrate is another thermal factor to consider. While not all materials have a thermal conductivity that increases with volumetric expansion coefficient, it is still preferable to choose a substrate with a higher thermal conductivity since it transfers heat away from heated components and results in a more even temperature distribution across the board. This inhibits the creation of hotspots and localized volumetric expansion around active components or high-current traces.

If these traces have an extremely high current, they can be dangerous.

PCB Thermal Management for Various Applications

Higher thermal conductivity substrates help with thermal management and passive cooling, which lowers board temperatures in industrial electronics, automobile applications, cellphones, and other applications. This makes it possible for heat to dissipates more frequently over the PCB, resulting in a temperature distribution that is more uniform. To control the temperature rise, various other basic passive cooling techniques or active cooling parts can be employed, such as thermal pads (Epoxy fileed, copper paste filled or copper coin filled), heatsinks on critical components, cooling fans, arranging multiple planes in inner layers, and by choosing good thermal insulation material (HITG).

Materials for Ceramic PCB Substrates

Ceramics have far better heat conductivity than FR4, PTFE, and polyimide, but at the expense of higher manufacturing costs. Multilayer manufacturing is challenging due to the difficulty of drilling these mechanically robust substrates, both mechanically and with lasers. Since the nanoparticles of these materials will sinter at the same temperatures as ceramic PCB substrates, ceramic PCB substrates can likewise be utilized with sintered gold or silver conductors with ease. 

For heatsinks, thermal paste vs. thermal pads

Heatsinks serve as a big reservoir to trap heat and transmit it to the surrounding environment. There are two ways to attach heatsinks to active components: thermal paste and thermal pads. A heatsink needs to be mechanically fastened to its component, or it can be bonded with thermal paste or a thermal pad. While thermal paste will outlast any thermal pad in terms of wear and tear, different pastes offer varying degrees of heat dissipation. These materials also allow for the combination of a heatsink and fan to provide powerful cooling directly to active components, such as CPUs, GPUs, FPGAs, and other components that switch quickly.

Dynamic Power Regulation

This technique, which is commonly used in mobile devices too small for active cooling, involves actively turning various functional blocks on and off as needed, as well as putting components like microcontrollers into sleep mode to conserve power and get rid of a heat source in the system. When combined with some special substrate material or metal core PCB, one can make up for the low thermal conductivity of standard PCB substrates.

Two fundamental types of boards with only one or two layers of conductive materials over the substrate are single-layer and double-layer PCBs. Multi-layer printed circuit boards are well-suited to satisfy requirements for increased routing space or signal integrity. Multilayer PCBs, as opposed to single- and double-layer PCBs, stack several layers of conductive and insulating material to produce an intricate web of connections. Prepreg, substrates, cores, and copper layers are usually included in the stack-up. In PCBs, there are two different kinds of insulating or dielectric materials: prepreg and core.

Conclusion

After reading about PCB substrate, you may be unsure about where to make your purchase. A PCB substrate may not always need to be purchased separately. You can discuss your needs with a PCB manufacturer, like PCB Runner, by getting in touch with them. In order to jointly determine which Multilayer rigid PCBs substrates best suits your needs, you can have a discussion. In this sense, PCB Runner will be beneficial.

In  material selection and PCB production following manufacturing issues might occur: 

Materials: Certain materials work well for certain circuits when it comes to the materials required to create a PCB, for example. Ultimately, they won’t offer the optimum signal integrity performance if alternative materials are specified in the board layer stack ups. Additionally, there are instances where the materials needed for the design aren’t economical to manufacture or appropriate for the board’s working settings.

The greatest method to guarantee error-free production is to work with a quality CM to optimize your design. You’ll find that they are an excellent source of DFM information. 

To accomplish this, your CM must to have a group of engineers who can check your design for DFM problems and offer suggestions for improving production. A group of component engineers should also be able to examine your parts, so you won’t be caught off guard by any that are unavailable or not advised for production.

Naturally, there may be instances in which you have a board that needs to be manufactured quickly for a proof of concept, product demo, or prototype, and you won’t have the time to work through all of the DFM concerns. Thankfully, the majority of CMs can assist you by utilizing what you already have. Sometimes the CM can adjust quickly. At times, during production, they will make impromptu corrections to manufacturing issues. The true secret is to collaborate with them in advance and address as many DFM concerns as you can in the original design to minimize the amount of cleanup that needs to be done afterwards.

To avoid typical PCB manufacturing issues, collaborate with a CM who possesses exceptional ability to fulfill your requirements. Selecting a partner with the appropriate experience and knowledge will guarantee that even the most challenging PCB designs are constructed and finished to your satisfaction.

Process followed for special material PCB design and production

Analyzing requirements and choosing components

Analyzing the requirements and choosing the right components, such as the CPU and power supply, is the initial stage in PCB design. Design a blueprint that satisfies every need.

Front end design within the system

PCB design software is first used to create PCB layouts. Commercial software for PCB design includes Altium Designer, Autodesk EAGLE, KiCad EDA, and OrCAD. A PCB schematic Gerber file is often the result of this design. Copper tracking layers, drill drawings, component nomenclature, and other parameters are among the data encoded in gerber files.           

Photo tool Launch

Before beginning the production of circuit boards, the Design for Manufacture (DFM) check must be performed. This is to prevent design inconsistencies. Subsequently, a laser printer/plotter is used to image the PCB onto a photo film. Accurate registration holes are punched into each film sheet to align the various layers of the PCB picture film. The purpose of the film is to assist in the creation of a copper path figure.

 Inner layer printing

The substrate is taken, chopped, cleaned, and dried. It is often a composite epoxy substrate. The substrate has copper pre-bonded to both sides of it. The most crucial element in preventing short circuit or open circuit problems is panel cleanliness. 

Removing the undesired copper with etching 

After that, unhardened copper material is removed from the panel by washing it in an alkaline solution. Beneath the photoresist layer that has solidified, the desirable copper layer is completely shielded. After that, the photoresist covering the copper layer is likewise taken off. Thus, the only copper layer that remains intact is the necessary one.

Punching registers to align layers

Registration holes are created by aligning and visually punching the various layers. The inner and outer layers will line up as a result.

Optical inspection carried out automatically

Errors in inner layers cannot be corrected after lamination. Therefore, prior to bonding and lamination, the panel is put through an automated optical inspection process. Using a laser sensor, the device examines the layers and, if any inconsistencies are found, lists them by comparing them to the original Gerber file.

Build up and Connect 

An aluminum press plate holds the PCB panel’s layers together. Copper foils are pressed over the original layers of a double or multiple later PCB, with insulating layers positioned in between, and the etching process is repeated. Ultimately, the PCB panel receives its final shape from the lamination of all the layers together.

Drilling 

Next, holes are drilled into the PCB stack. The electronic components of the PCB, including the via holes, are supposed to be positioned and connected in these holes. A drilled hole has a diameter of between 100 and 150 microns. Drilling is an exact technique that requires precision. To attain accuracy, one can utilize X-Y coordinate systems or laser locators.       

Platting and Copper Deposition 

After drilling, this procedure involves applying a new layer of copper to the entire panel. It covers the nonconductive materials that were exposed following drilling and also ties the panels together. For plating, a chemical electrolysis setup is employed. To guarantee correct connection, approximately 25 microns of copper are inserted into the drill holes.

Copper etching and outer layer imaging

A photoresist material is put over the outer copper layer, just like in step 3, and they are then photographed. The excess copper is removed, and a protective tin guard coating is placed over the necessary copper region. This is followed by the establishment of PCB connectors.

Application of Solder Mask

After cleaning the board, the solder mask is put on. The purpose of the solder mask is to shield the board from corrosion and copper oxidation. Applying an epoxy and a solder mask together gives the board its typical green hue. UV light exposure removes unwanted solder mask. The board is then cooked in the oven.

Silver or gold surface polish

After that, the PCB is plated with a hot air solder leveling finish or lead-free HASL in gold, silver, or bronze. This protects the copper and makes it possible for the components to be soldered to the pads that are made.

The silkscreen

The process of printing all of the important information on the PCB, including component numbers, manufacturer identification, company name, and debugging locations, is called silk-screening or profiling. This is helpful for maintenance and repairs.

Conduct an electrical test

Probe testers are used for electrical testing. Tests for both open and short circuits are run. Functional reliability is ensured via electrical tests. Functional tests are followed by durability testing.

V-Measuring 

The fabricated panel is cut to reveal the real PCB. PCBs are cut to precise dimensions and forms in accordance with the customer’s design and the original date on the Gerber file.
The board may be readily removed from the panel thanks to the V-cuts created along its sides.

Packing and final examination 

PCBs go through a quality and final visual check. Test results are given to customers for validation. To avoid any physical damage to the boards, the packaging is either vacuum sealed or airbag/air pocket packaged.

Quality of PCB Manufacturing 

During the process of fabrication and assembly, quality requirements are maintained by: 

• Statistical process control monitoring rates of scrap and defects 
• Thorough inspection verifying the output of the operation 
• Frequent machine calibration and maintenance 
• Adherence to strict industry standards such as ISO and IPC 
• Tight supplier quality control procedures 
• Supervision of the manufacturing floor environment for quality assurance 
• Thorough examination of the completed boards, in-process materials, and raw materials 
• Initiatives for continuous improvement to reduce flaws 
• Quality control guarantees dependable, consistent PCB production.

Applications of Special Material PCBs

Medical area

The following are a few typical medical PCB devices: Medical imaging systems: CT, CAT, ultrasound scanners; monitors: blood pressure, glucose, and heart rate monitors; and the computers that gather and interpret these images.
insulin and patient-controlled analgesia pumps are examples of infusion pumps. inside gadgets, such as pacemakers. PCB contributes significantly to raising the standard of medical care by providing tools and equipment that help physicians discover problems and increase their accuracy and efficiency. 

End-user devices 

Flexible printed circuit boards, or FPCs for short, are a type of PCB made primarily of polyester or polyimide film. FPC gains popularity with its high density, light weight, thin thickness, bending resistance, flexible construction, and resilience to high temperatures under the trend of intelligent and thin mobile electronic products. The following consumer electronics include PCBs. Communication devices, such as radios, tablets, smartphones, and smartwatches. Entertainment systems include stereos, video game consoles, and televisions. home appliances, such as coffee makers, microwaves, and refrigerators. 

Aerospace sector

The aerospace sector has more stringent specifications, requiring PCBs to be durable and resistant to oxidation. The primary USB of any operating system used by the aerospace sector is the PCB assembly with heat management. The PCB heat dissipation design can be implemented using a compact architecture for heat dissipation. Heavy-duty, highly tailored PCBs are essential to electronic equipment used in aircraft. In the aerospace sector, PCBs are used in the following ways: power: satellites, control towers, and airplanes;  accelerometers, pressure sensors, and communication equipment as surveillance tools.

Applications for the military and defense

PCBs are used in many different applications, such as computers, guns, cars, and communications equipment. Military equipment frequently uses materials like copper, aluminum, and high-temperature laminates. The applications are listed below. Radio communication systems are examples of communication equipment. Control systems, including missile detection and radar jamming systems.
