Electroless nickel peeling from copper


(1996)

Hi guys!

I'm having some problems with my electroless nickel layer, in our line we are using a copper plate which is cover with a electroless nickel layer (Ni-P) and after with a tin/lead layer, during an aging test we are facing a problem, the nickel layer is peeling off from the copper, If you have faced similar problems or have some knowledge about this please send to me your inputs.

thanks in advance for your valuable help

regards

We put a nickel strike on everything before applying electroless nickel. I think it helps adhesion as well as providing a catalytic surface.

In order to assure good adhesion between copper and EN you need to activate copper with a strike nickel or a short current in the EN solution.
