Detail specification
High-Tg Substrate
FR-4 with Tg ≥170°C (DSC), Z-axis CTE ≤50 ppm/°C; withstands 260°C lead-free reflow multiple times.
Preventing board warpage and delamination under high power and thermal cycling.
Most Challenging: Drilling high-Tg materials (brittle, prone to burrs) and controlling resin flow during lamination.
Conformal Coating
Polyurethane (UR) or silicone (SR), 50–80 μm thickness; passes salt fog (5% NaCl, 48 h), condensation,
and 85°C/85% RH for 168 h.
Outdoor corrosion and moisture protection – essential for field durability.
Selective coating of connectors, test points, and heatsinks; achieving uniform thickness and adhesion, plus rework difficulty.
Solder Joint & Mechanical Robustness
Power component shear force ≥15 kgf; BGA voiding <15%; passes 2g vibration (5–500 Hz) and 30g mechanical shock.
Withstanding road-induced vibrations and thermal-mechanical stress.
Balancing large thermal-mass joints with small BGA voids – requires tight reflow control and X-ray screening.
