Critical Production Processes

Material and Design Selection

High-Tg (≥150°C) or BT resin materials must be selected to ensure long-term heat resistance and moisture resistance
ENIG surface finish is preferred, with nickel layer thickness of 3-6μm and gold layer thickness of 0.05-0.1μm to avoid "black pad" risk
Trace width/spacing should be controlled at 0.1-0.15mm, with characteristic impedance deviation stricter than ±8%

Key Production Process Controls

Drilling and Hole Metallization: Coated drill bits must be used to reduce hole wall burrs. After desmearing, backlight testing (≥Grade 9) is required to ensure hole walls are free of cracks
Pattern Transfer and Etching: LDI exposure equipment should be used, with line width tolerance of ±10%. After etching, 100% AOI inspection must be performed to screen out undercuts and shorts
Lamination and Flatness: Symmetrical stack-up design is required, with post-lamination warpage ≤0.5% to prevent SMT soldering defects such as insufficient solder or open joints
Solder Mask and Surface Finish: Solder mask ink must be resistant to chemical cleaning (e.g., IPA), with no residue after development. Before ENIG, plasma cleaning must be performed, with ionic contamination ≤1.5μg/cm²

Reliability Verification

Each batch must undergo solderability testing, high-temperature high-humidity testing (85°C/85% RH, 168 hours), and temperature cycling testing (-40°C to 85°C, 100 cycles) to ensure long-term electrical stability in sterile environments
