ENEPIG vs ENIG: Choose the Right PCB Surface Finish
ENIG and ENEPIG are both flat, solderable PCB surface finishes. ENIG uses electroless nickel and immersion gold. ENEPIG adds an electroless palladium layer between the nickel and gold. In the ENEPIG vs ENIG decision, a controlled ENIG process is sufficient for many conventional SMT assemblies. ENEPIG becomes more useful when wire bonding, mixed interconnection methods, […]
