Dave: It's good to know what that stuff is. With your NiO, you have the typical ENIG problem. I can imagine some causes for your disaster: * too thin gold plating * oxidized nickel under gold plating * porous nickel plating * wrong soldering pr

Grant The solution to soldering problems with immersion gold boards is: find a supplier that can control his/her process. Electroplated gold over nickel is a very reasonable process. Billions of wire bound boards use it evry year.

Steve - I believe you should ask who has NOT dealt with this before. Search the archives for "dark pad" or "black pad". It's a common problem for immersion Gold. Does anyone Know any other descriptive names that I missed (and can be printed

Paul We don't like to mix metals on press fits. Yano, we do gold on gold or solder on solder, but we don't mix metals [except with imm silver / tin] to avoid electrochemical corrosion. Is that bad information or does AMP think that's not a problem

Hello !! I have a problem with my wave solder oven, in one of the products we made has connectors on one side of the pcb and in the other one has SMT components the process is kinda tricky on the SMT components we use an adhesive and put to the refl

Hi! From your post, it seem like the wave did not really touch the component. You probably need to get the both wave height correct and that it hits the component.It is normal for solder to come through the PCB when using chip wave. The through-hole

Details, details: 1) The metal shell is part of the component body. The base metal is austenitic stainless steel (304) that has been plated with 90/10 tin-lead over nickel (semi-bright). 2) The entire part (leads and shell) is elevated by the mass o

No clean solder paste. One further observation ... the parts have a metal shell and are 'floating' high on the paste. Though there is wetting on the metal shell, it doesn't seem to sink as far as it should and this could be lifting the soldertails f
