What is enepig?enepig-electroless nickel electroless palladium immersion gold is a surface finish for printed circuit boards.enepig works well with lead free and conventional eutectic solder alloys.this is the best way for gold wire bonding. We can offer quick turn enepig pcb with low cost.0.2mm pcb will be ok.rigid(0.2mm), you should be veryshocked.but we can make this.
