Hi Technos,

I'm having a tough connector here, hard time to get all the pins soldered.

It is matte Sn over Ni finished, measured coating thicknesses are 250 microinch Sn over 80 microinch Ni. Are these values OK? Isn't the Ni too thin and the Sn too thick?

The manufacturer spec is 0.001mm (40 microin) minimum Sn over 0.0013 (51 microin) minimum Ni.

Thanks for your input,

Ioan
