Teh amount of silver on an immersion silver board won't effect 62/36/2 tin/lead/silver solder, however if the silver on the board is on the thick side and you have a high trace silver content in a 63/37 tin/lead then with the combination of the two y

| | We are currently investigating alternatives to HASL for circuit boards with 20 mil pitch smt pads and below. If you have experience with this product or simular immersion tin products with respect to manufacturing or assembly I am very interest

I've been building boards for a long time and have never heard of anyone using electrolytic silver. Immersion silver would be 8-18 microinches thick. Plated silver would be significantly thicker (min a couple tenths - .0002" and up). So you may be ab

Good morning, I got a question regarding Immersion Silver Board Finish. It has been imposed on us by our customer that we must manufacture PCB through the SMT process within 24 hours of breaking the seal on a bag of PCB containing Immersion Silver.

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

We are considering the use of Immersion Silver for a PCB surface finish. We currently use Immersion Gold surface finish, which has served us well. However, recent discussions on the cracking of corner joints on large pin count BGA packages, with the

Has anyone done any experiments with Immersion Silver plating on PCB's? If so, What are your experiences with it?

Converting to immersion silver is the best solution to the "black pad problem".

Make the move to Silver Immersion, no nickel to mess with!
