  • Surface Mount and Through-Hole Assembly: The accuracy and precision in placing components.
  • Component Packages: The compatibility of different component packages with the PCB layout.
  • Quality Grade: The overall reliability of the assembly, especially for mission-critical applications.
4. Testing and Inspection for Quality Assurance

Comprehensive testing and inspection are fundamental to ensuring the quality of the final product. Here’s how quality is assured:

  • Bare PCB Testing: Techniques like electrical testing, flying probe testing, and bed-of-nail testing are used to verify the functionality of the bare PCB.
  • Assembly Testing: Advanced inspection methods, such as Automated X-ray Inspection (AXI) and Automated Optical Inspection (AOI), help detect potential issues like solder defects, misaligned components, and faulty connections.

These testing phases help identify errors early, reduce costly rework, and ensure that only fully functional products proceed to the market.
