Quantitative 3D surface profiling inspection of glass core PCB using nanometer resolution off-axis digital holographic microscopy

Accurate 3D surface profiling of glass core printed circuit boards (glass PCBs) is critical for the reliability of advanced electronic packaging. Conventional automated optical inspection methods provide only 2D information without quantifying surface height, while white light interferometry suffers from slow speed and...
