In the electronics business, sourcing components is essential for locating PCB parts and other components needed to complete circuit boards and component boards. Resistors, capacitors, integrated circuits, transistors, diodes, and other components may be used in this process. In order to guarantee the quality of the product, the components must also be obtained from reputable vendors.

 Depending on the PCB components required, acquiring components may need collaborating with both local and foreign vendors. It is essential to consider elements like cost, lead times, quality, availability, and minimum order quantities while purchasing PCB board components. To ensure proper operation, printed circuit board components also need to be compatible with other parts of the circuit.

 Before being utilized in manufacturing, the circuit board parts that are purchased from suppliers need to be inspected. This involves verifying that the parts meet safety, performance, and quality standards. To make sure they comply with industry standards and laws, circuit board components must also be properly labeled, kept, and tracked.

To put it briefly, obtaining electronic components is essential to the electronics sector because it guarantees the dependability and safety of the final goods.

The Challenge of Locating PCB Components is Mostly Caused by Three Variables

1. Complicated Design Specifications

For electronics makers, there are new design problems arising from IoT devices, hardware related to artificial intelligence, and growing demand for eco-friendly equipment. PCBs for similar items frequently need:

Flexibility: Complex designs and smaller items could call for flexible printed circuit boards. Finding a flexible PCB that can handle the design is one thing, but finding one without excessive material prices and assembly steps is quite another.

Sustainability: Lead times and costs may rise as a result of the growing demand for environmentally friendly materials and production techniques.

2. Disruptions to the Supply Chain

The COVID-19 lockdowns continue to generate supply chain issues that could impede the procurement of PCB materials like copper and base laminates in numerous industries.

 Beyond the pandemic’s effects, PCB manufacture has been further burdened by the rising demand for copper in 5G devices and electric vehicles. 

3. Few Local Vendors

Depending on the location of electronics manufacturing, locating trustworthy local PCB suppliers can be challenging.
Using regional vendors has several benefits, including: 

  • Collaboration made easier
  • Reduced freight charges
  • Adaptability and reactivity

A simpler way to confirm quality controls Businesses can save time and money by locating a trustworthy local PCB provider, but the options aren’t always plentiful. It’s possible that local PCB assemblers won’t have access to the appropriate tools or materials for the job, even in the event that manufacturers do have access to such services.

The Value of Selecting a PCB Manufacturer for Your Requirements

In addition to potential substitutes for those difficult-to-find parts, we’ll look at some of the greatest web tools for finding components in this post.

7. Parts and their accessibility

Usually, components are grouped according to their availability. For every component, there are typically 5 levels of availability:

1) The part is still manufactured and stocked.

2) The part is still made, however it is not available.

3) Although the part is no longer produced, it can still be available as a salvage product.

4) The part is no longer in production and won’t be available in salvage form.

5) The part is no longer in production and can only be found in salvage condition.

8. Internet-based sources for parts

Websites in the nature of marketplaces have proliferated online, providing a wide selection of parts from competing vendors. Reputable electronics websites abound and provide a vast inventory of parts that are simple to search by brand or category. Marketplaces allow customers to look at what’s available for a wide variety of products. They could aid in time savings for purchasing managers.

 Because technology is developing so quickly, electronic component obsolescence is at an all-time high. OEMs are facing significant challenges in keeping up with the ever-increasing demand for electrical components in the electronics industry due to widespread innovation.

Recognizing the Dangers of Obsolescence and Advanced Techniques for Component Sourcing

 Since every component has a finite lifespan, component obsolescence is inevitable over time. Every component eventually becomes outdated. On the other hand, component obsolescence is happening faster and faster. This indicates that you are dealing with more difficulties.

 Managing the obsolescence of electronic components

 Knowing that obsolescence is inevitable in sufficiently long a time, how will you handle the difficulty when it arises?

 Recognize the reasons of obsolescence

 Three primary factors contribute to the obsolescence of electrical components: shorter product life cycles, rising demand, and innovation. These come together to form the ideal storm. The rapid advancement of semiconductors is a prime illustration of this storm. Which obsolescence causes will have the biggest impact on you? Knowing this will help you to properly plan for the future

When creating a product, consider its lifespan

 Creating products with components that aren’t anticipated to become outdated during the course of the product’s lifecycle is the strongest defense against obsolescence.

 There are several techniques to guarantee longevity:

  •  Review the component’s “Production Status.”

 Find out from your provider how long the components last. If the datasheet was created more than a few years ago, this may be a sign that the part needs to be upgraded soon. It may take several years for a component to become obsolete, even if that is the case. Your company will benefit greatly from this understanding.

  • Discover the true nature of obsolescence

When you receive a message that a component you use is getting outdated, investigate the cause of the issue from a distance.

The PCN (Product Change Notification), which has the necessary technical information, can be examined to do this.

There’s a strong probability that you can locate a comparable component if the component is passive. You might need to update to a newer component if the old one is still functional.

When Obsolescence Occurs, how to Handle it?

When it comes to handling obsolete components, you have three options:

 Equivalency: this is the process of searching for a comparable part. Many components, including semiconductors, have cross references that allow you to locate identical equivalents. To make sure there is cross compatibility, you should check the datasheets.

 Design is the process of collaborating with an OEM to have a component manufactured on your behalf. Because the component is specific to you, there is less risk but a higher expense. Micro-controllers and NANDs are typical examples.
Use outdated stock; there’s undoubtedly a component in storage someplace in the world that you require. If you can locate it, you can get this. To obtain the components you require in this situation, an electrical component distributor is your greatest ally.

Strict Quality Control Measures and Component Verification Procedures

 PCB contract manufacturers will employ their internal technical staff to review the design and assess the component needs in order to guarantee quality from the beginning. The parts listed on the bill of materials will often be acceptable, but the evaluation will be on the lookout for the following issues:

 Performance: For some circuits, there might be better possibilities where a different component or a different design will improve the PCB’s performance.

Cost and Availability: Even though the components are high-quality, the circuit board cannot be finished if they are too expensive or unavailable.

 Component life cycle: Production of circuit boards will be impacted by parts that the manufacturer decides to discontinue before the project’s anticipated completion. Before production begins, it is preferable to replace outmoded or end-of-life parts rather than redesigning them afterwards.

Thorough engineering review is a crucial step in the entire quality control process that guarantees a circuit board is manufactured successfully. In a DFM review, the design’s manufacturability will be assessed concurrently, and the customer will be advised of any necessary modifications. The next stage of the quality control procedure will start with the acquisition of parts and materials after all inspections have been finished and any required adjustments have been made.

Applications in Sectors like Aerospace, Defense, Industrial Automation, Medical Devices

  • Applications in aerospace, defense

Electronic manufacturers in high-reliability sectors such as aerospace, medical, and military have historically placed a strong emphasis on managing component obsolescence. No sector of the electronics industry can afford to ignore its significance for long-term economic viability these days.

Numerous military and defense systems depend on electronic components that are no longer made by the original manufacturer or offered for sale by its approved dealers. These systems’ lengthy lifespans serve as one of the foundations for this dependency.

Even though an electronic component might only be produced for two years, many defense systems that utilize them might last for over 20 years. Electronic components that are older frequently require testing and retaining in order to prevent solderability problems such as tin whiskers.

These highly dependable businesses rely heavily on a technology that becomes outdated in a matter of years, if not sooner, is produced in unsafe conditions, and has little control over market dominance.

  • Applications in medical

These issues—staffing shortages, worldwide component shortages, and shipment backlogs—have only made the COVID pandemic, which is still raging in some regions of the world, worse. Massive delays and higher shipping costs were seen in almost every industry when manufacturing moved overseas.

 Specifically, the worldwide shortage of components has caused an 8–10 month delay in some orders for the medical industry. Additionally, legal and medical complications have made matters worse, and medical device OEMs have had to deal with grave worries around device obsolescence.

 The mitigation of obsolescence risk has become considerably more challenging due to shortages and bottlenecks in the supply chain. It can be necessary for certain medical device producers to schedule several years in advance to make sure their machinery doesn’t break down.

The issue of medical equipment obsolescence poses a significant challenge for healthcare organizations and practitioners.

 Choose components with long-term availability or multiple sources for all necessary parts to lower the risk of sourcing challenges and price volatility brought on by low supply or excessive demand. To guarantee a reliable supply chain, for example, opt to employ components that are frequently found in other industries, such as the automobile or aerospace industries. As a result, there is rivalry for their purchase, but it also guarantees that, as long as there is a large demand, they will always be accessible, usually from several sources. When these tactics aren’t an option, employ best practices to lower the risks associated with single-source components.
