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
