PCB knowledge: ENIG
ENIG stands for Electroless nickel immersion gold which is a type of surface plating used for circuit boards. It consists of an electroless nickel plating covered with a thin layer of immersion gold. Normally, the thickness of nickel is 120µ” - 200µ” (3µm to 5µm ) and gold 1-5µ” (0.025µm – 0.127µm).
ENIG has several advantages than HASL, including
a) Excellent surface planarity, particularly helpful for PCBs with BGA packages or even CSP mounted components to reduce failure rate during assembly and soldering.
b) Good oxidation resistance and good heat dissipation.
c) Long storage time ( It can be stored for more than 1 year in vacuum bag)
d) High solderability, no stressing of circuit boards and less contamination of PCB surface.
e) SMT process is resistant to reflow soldering, resistant to rework.
