I have read that edge connector fingers should have a hard plated gold to withstand repeated plugging in and out of the cards. Apparently ENIG is too soft/thin to withstand multiple pluggings. Do your PCB edge connector fingers have hard gold plating or just ENIG like the rest of the pcb?

The gold fingers has only normal ENIG and HASL.
