    Assessing Quality Control and Testing

    You need to focus on quality control and testing when you choose a pcb manufacturer. These steps help you avoid costly mistakes and ensure your printed circuit boards meet your requirements. The best pcb manufacturer uses advanced inspection and testing methods to guarantee reliability.

    • Automated Optical Inspection (AOI) detects defects like misalignment and open circuits.

    • X-ray inspection checks buried vias and internal connections.

    • Electrical testing, including flying probe and bed-of-nails, confirms all connections work as intended.

    • In-circuit testing (ICT) finds open circuits or wrong components in high-volume runs.

    • Burn-in testing stresses the board to ensure long-term reliability.

    • Functional testing verifies the prototype circuit board works in real-world conditions.

    You should ask for documentation of these tests. The best pcb manufacturer will share reports and communicate any defects found during production. This feedback helps you correct design issues and improve future quickturn projects.
