Product Description:
ENIG Quality: Control the gold layer thickness (0.05~0.1μm) and prevent black pad — these are the foundation of solder joint reliability. Substrate Selection: Use high-Tg, low moisture absorption materials to ensure stability in high-temperature and high-humidity environments. Environmental Adaptability: Consider temperature cycling, salt spray, vibration, and other actual working conditions of security equipment. Testability: Reserve test points to facilitate ICT/FCT inspection. Process Control: Conduct batch sampling inspection for ENIG thickness, solderability, etc.
