ENEPIG (Electroless Nickel Electroless Palladium Immersion Gold) and ENIG (Electroless Nickel Immersion Gold) are two widely used surface treatments for PCBs. While both processes aim to improve the solderability, corrosion resistance, and long-term reliability of PCBs, they differ significantly in terms of process details, material choices, and performance characteristics.So what
The surface treatment of PCBs directly affects their performance, reliability, and production cost. Among the various surface treatment technologies, Immersion Gold (ENIG) has become one of the most widely used and efficient processes.
This article will provide a comprehensive understanding of the PCB immersion gold technology, covering everything from design to
In the early PCB manufacture, HASL is the most widely used surface treatment, which has excellent welding performance and low cost.With the high precision PCBs developing, it is difficult to below the surface to smooth of HASL, which brings difficulties to SMT mounting. In addition, the service life of HASL
