Blistered Plating at the Nickel Interface to Extruded Base Aluminium 6063




Extruded Aluminium (6063)that has been zincated (Twice), electroless nickel 2 microns and silver plated 6 microns. With a pre 200 and post 150 degree C bake is blistering at the alum interface.

Process to manufacturer guidelines I'm told.

Porosity none found.

Most blistering occurring after reflow soldering operation 230 degrees C for 1 minute

Any suggestions?

Dear Bill,

I did not understand, why you are using electroless nickel as an undercoat before silver? Remove electroless nickel before silver plating, you will probably solve the problem of blistering.
