Critical Production Processes

Inner layer core board target punching accuracy: ±25μm
Hot melt riveting fixation to prevent board sliding during lamination
LDI exposure equipment for inner layer pattern transfer with increased exposure energy compensation for fine line areas
100% AOI inspection and line width measurement after inner layer etching
Low-flow prepreg lamination process with temperature ramp rate maintained between 1.5-2.0°C/min
Scanning acoustic microscopy for delamination and void defect detection
Coated drill bits with optimized retract speed to reduce burrs
Plasma treatment before electroless copper deposition for improved hole wall adhesion
V-cut or routing processes for final shaping to prevent fiberglass burrs
