PCBA Reliability Testing

PCBA reliability testing subjects assemblies to environmental and mechanical stresses to predict lifespan and failure modes. Thermal cycling (-40°C to 125°C, 1,000 cycles) identifies solder joint cracks in automotive IGBTs, where temperature swings cause CTE mismatch between PCB (17ppm/°C) and compo

PCBA In-Line Inspection

PCBA in-line inspection integrates automated optical inspection (AOI), 3D solder paste inspection (SPI), and X-ray to detect defects early in manufacturing. AOI systems use high-resolution cameras (5μm resolution) to check component placement, polarity, and solder joint quality at 0.3 seconds per bo

PCBA Debugging and Validation

PCBA debugging and validation resolve functional discrepancies by combining root-cause analysis, signal tracing, and firmware adjustments. Boundary scan (JTAG) tests embedded processors in smartphones, isolating faults in 10 minutes vs. 2 hours with manual probing. Oscilloscopes with 16GHz bandwidth

X-Ray PCBA Inspection

X-Ray PCBA Inspection is a non-destructive testing (NDT) technology that uses X-ray radiation to visualize internal and hidden defects in Printed Circuit Board Assemblies (PCBAs)—defects that are invisible to traditional optical inspection methods (like AOI). Unlike AOI, which relies on visible ligh
