90 Knoop. Q2: Thickness is 4 to 10 u" for Au and 300 to 400 u" for nickel A2: This looks like a ENIG spec. Although, the Ni is quite heavy, 150 uin is sufficient for most applications. [IPC-4552 ENIG specification: * Gold thickness of 0.075 - 0.125

I have had an issue where solder has contaminated gold plated pads (fingers) where it is not acceptable. The pads must remain perfectly coplaniar for a LCD zebra strip to lay accross them. Does anyone know of a way to remove the marriage level of s

| Does anyone know if I will have problems soldering surface mount components to an all hard gold plated PC board. We want to use hard gold similar to gold used for edge fingers because our customer is concerned about wear and conductivity of connect

We have a board calling out for 50 micro-inches of nickel over 30 micro-inches of gold. This is a solid gold board on Rogers material. ENIG cannot be deposited that thick right? Electroplated gold (we thought) was usually 35-50 micro-inches and was

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.

Electroplated nickel and electroplated gold is the more �traditional� finish for aluminum wire bonding. That surface was an extension of gold thermosonic wire bonding that requires a thick [50 thou min] gold surface. For years fabricators recommend

I would agree with Doug, Enig with this type of switch is doubtful that it will hold up. You may have to think about Electroplated Deep Gold (hard Gold) 30-40 micro inches. Regards, Mike

| Can someone help me find info on gold repair? I know it can be done, but I need to know how expensive it is, etc. | If you're talking "hard" electroplated gold, as used to plate PCB contact fingers, you can do the process inexpensively or send it

Good Morning, I have been working with a company that has a selective electroplate touch up system from Rapid Electroplate. They have used this for repairing gold electroplate. Scratches and in some cases, replating pads that had been contaminated w
