Critical Production Processes

Vacuum lamination technology for inner layer pattern transfer to ensure tight adhesion and prevent bubble generation
Automated Optical Inspection (AOI) after inner layer etching to detect defects including undercuts, pinholes, and shorts
Strict control of temperature ramp rate (1.5-2.5°C/min) and pressure profile during lamination to prevent delamination
Coated drill bits for drilling process to reduce hole wall burrs, followed by desmearing and potassium permanganate cleaning
Plasma treatment before electroless copper deposition to improve hole wall roughness and adhesion
Backlight testing after copper deposition to ensure quality
Board brushing and sandblasting before solder mask spraying to improve ink adhesion
Parallel light exposure machine for solder mask exposure with energy uniformity ≥85%
Micro-etch roughening treatment before lead-free HASL with micro-etch depth of 1.5-2.5μm
Board baking (120°C/1h) to remove moisture and prevent solder splash
Controlled vertical board withdrawal speed during HASL for uniform tin layer thickness (±5μm)
Cooling and flattening after HASL with warpage inspection (≤0.75%)
100% electrical testing using flying probe or universal fixture testing
