1. Identify Required Components
In the beginning of the component sourcing process, it is crucial to define exactly what components are needed for the design. This process starts with understanding the overall circuit design, whether it’s for a PCB, embedded system, or another electronic device. The engineers must specify which components are required, considering factors like:
-
Type of Components: Whether the components are passive (resistors, capacitors), active (transistors, ICs), or electromechanical (relays, connectors).
-
Electrical Specifications: Voltage, current, power ratings, and frequency specifications are essential in choosing the correct components.
-
Size and Form Factor: The dimensions of the component need to fit the available space on the PCB and the overall product design.
-
Tolerance and Reliability Requirements: Some designs may require components with very tight tolerances or with high reliability for critical systems.
Once the components are identified, the next step is to document them in a Bill of Materials (BoM). This is a detailed list that specifies the part numbers, manufacturers, and quantities for each component. It serves as the foundation for the sourcing process, ensuring that every part required for assembly is accounted for.
