At JLCPCB, all PCBs undergo comprehensive AOI(Automated Optical Inspection) to ensure quality. AOI detects any breaks or imperfections in traces. PCBs tested with AOI achieve a quality rate of 99% or higher.
Flying Probe Test: This is the final checkpoint for circuit continuity. It can test for open and short circuits.
- Full Test: 100% pass rate, but is slower and incurs a fee due to it is time-consuming.
- Random Test: Free of charge, ensuring a minimum pass rate of 99%.
E-test Fixture: Provides rapid testing and is suitable for mass production, although it requires a high material cost.
