The Importance of Testing and Inspection in PCB Assembly

Testing ensures that each PCB performs accurately and reliably. Customers rely on thorough inspection to verify that their products meet quality and performance expectations.

1. AOI, SPI, and X-ray Inspection

   Automated Optical Inspection checks component polarity, missing parts, and solder quality. SPI ensures accurate solder paste volume, while X-ray reveals hidden issues in BGA and QFN joints.

2. Functional Testing

   FCT simulates real operating conditions, verifying that the PCB behaves as intended under load. This is essential for microcontrollers, communication modules, and complex digital systems.

3. Burn-In and Reliability Testing

   Extended reliability testing exposes PCBs to elevated temperatures, continuous power, and stress conditions to ensure long-term durability.
