Hi Technetters, Anybody using immersion tin as a surface finish? What are some of its quirks? We have a customer that wants us to use it, so we are going to qualify it as soon as we can get some boards in from multiple suppliers. During the qual, I would like to know ahead of time what problems to look for. We are currently assuming it will be a drop in for our OSP and immersion gold boards. (We got rid of HASL a while ago because of shorting on fine pitch is orders of magnitude high than gold).
