Hi Michael While driving home last night I realized the omission in my response. I thought someone would call me on it. I should have clarified that the dissolution of the gold into the joint would be affected by the thickness of the gold plating,

Hi, What is the different between Electroless Nickel / Immersion Gold (ENIG) and Immersion Au. Are they refer to the same finishing? We has been using the Gold thickness (0.00005 - 0.00013mm) , nicket (0.0025mm) for all Gold finishing brd (Immersio

There's a lots comparisons like this on the web. Here's one: Westwood Associates said on 8/12/2003: ||HASL||OSP||ENIG||Pd||Tin||Silver Flat||no||yes||yes||yes||yes||yes Solderjoint||Cu-Sn||Cu-Sn||Ni-Sn||Ni-Sn||Cu-Sn||Cu-Sn Contact||E-test, ICT||no|

should gold pads be pretinned, what issues are known are there?

Dave, anything besides gold embrittlement to be concerned about if that concentration is exceeded? Never tried the stuff.

Gold in solder alloys can be brittle. We always used to talk about keeping gold LT 3% in order to avoid embrittlement. Some military contracts require removal of gold from soldered contacts. Adding gold to a solder alloy that you're familiar with wi

I have lots of experience with thermosonic gold ball bonding. You can read the literature and you will probably find some papers that say you can do it. I have never been able to do it. We gold ball bond all day long with little problems at all bu

Hi, I believe you have classic gold imbrittlement here. With 80 microinches of gold you are way over the limit. You can try to reflow longer time and at a higher temperature. The gold does not melt into the solder joint. The gold dissolves into

Hi Russ, I have a similar situation. I have been told that this can be caused by the nickel, over which the gold is plated, can result in suspect joints, embrittlement etc. Some joints can even be weak and broken without much force on some of my boa

John: What�s the matter? Free gold � good thing for you, bad thing for your supplier. :^) Pre-tinning of gold plated leads is important to: � Prevent gold embrittlement of the solder joint � Determine if the leads are solderable prior to assembly (

ENiG or IAg? Which is better?

Electronics Forum | Thu Mar 06 11:48:09 EST 2008 | muse95

Black pad with IAg??? Tarnish is NOT black pad. Tarnish is usually just some silver sulfide on the surface and can also usually be soldered through, by using a little additional, or slightly more agressive, flux, and still make a good quality solder
