A Printed Circuit Board (PCB) is crucial in virtually every electronic device, providing a platform for various components tailored to specific functions. With advancements in Artificial Intelligence (AI), digital circuits, and the automotive market, electronic technology continues to evolve rapidly. As electronic boards become smaller and more complex, PCB board parts have similarly advanced to handle multiple tasks and fit intricate spaces.
The Bill of Materials (BOM) for a PCB lists components, which are generally categorized into Passive and Active components. This comprehensive list includes part numbers, suppliers, quantities, and units of measurement, and may also detail alternative parts and lifecycle status.
These components require an external power source to amplify or modify signals. Integrated Circuits (ICs) are a key example, consisting of miniaturized semiconductor chips that integrate various circuit functions.
These do not require an external power source to function. They store, resist, or maintain electricity and are often described by their dimensions (e.g., "0603" for 0.06”x0.03”). Examples include resistors, inductors, and capacitors.
Key PCB board parts include:
Passive components that resist current flow.
Store and release energy, affecting current flow.
Semiconductor devices allowing current to flow in one direction only.
Semiconductor chips with integrated tiny components.
Semiconductor devices that amplify signals.
Facilitate electrical connections between circuits or devices.
Generate precise periodic signals for timing and synchronization.
Electromagnetic switches that control high-power circuits with low-power signals.
Transfer electrical energy between circuits, adjusting voltage and providing isolation.
Sourcing PCB components involves several critical factors:
It’s wise to include alternative parts in your list to avoid supply disruptions. This strategy helps mitigate delays caused by part shortages or discontinuities, especially for active components.
Stay updated on material availability and pricing fluctuations to adapt to changes and avoid procurement issues.
Build relationships with reliable suppliers by setting criteria such as quality methodologies, experience, and technology capabilities. Consider on-site visits to assess their facilities.
Develop partnerships with suppliers who can ensure supply chain continuity and effective procurement. Evaluate factors like geographical location and resilience to disruptions.
Effective sourcing is essential for successful PCB fabrication and assembly. Common challenges include:
Compliance with regulations can increase costs and complicate sourcing. Consider environmental impact early in the design and material selection process.
Stay updated with technological advancements and innovations to manage changing component prices and availability.
Custom parts may be necessary for complex PCB designs. Close coordination with PCB designers ensures components meet design specifications and maintain supply consistency.
