What is the disadvantage of palladium plating instead of gold plating? I saw many advantage of palladium plating in term of hardness, wear resistance, and price but why most of the PCB Industries still use gold in PCB pad? Thank you

ENEPIG or Imm Pd?

Concerns about palladium as a solderability protection are: * Palladium is more difficult to process in fab than gold * Palladium solder alloys can be brittle, similar to gold, without proper soldering process and/or specification/receipt of the correct palladium thickness.

Recognize that: * Palladium doesn't wet as well as gold * Dissolution rate of palladium is much slower than gold
