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
