Critical Production Processes
  • ENIG Process Control: Nickel layer thickness strictly controlled at 3-6μm with phosphorus content of 6%-9%, and gold layer at 0.05-0.1μm. Precise reaction time management to prevent "black pad" defects.
  • Pre-treatment Cleanliness: Efficient degreasing and micro-etching (depth 0.5-1.5μm) to ensure fresh copper surface with optimal nickel layer adhesion.
  • High-speed Signal Transmission: Characteristic impedance deviation controlled within ±8%, precise line width tolerance and etching factor management, with differential pairs maintained equal in length and symmetrical.
  • Dimensional Accuracy: Profile dimension tolerance controlled within ±0.1mm and hole position accuracy within ±2mil to meet compact assembly requirements.
  • Quality Verification: Comprehensive solderability testing and environmental reliability verification including high-temperature and high-humidity tests. Storage in dry, sulfur-free environment to prevent gold surface oxidation.
