OA Pb-Free Paste | 25 January, 2007

Does anyone have a recommendation for a good OA Pb-Free Paste? We are currently doing Pb-Free with a No-Clean that we are very happy with but we are going to start coming out with products with RF and I have researched that No-Clean residue and RF don't go together well. I know I could clean the No-Clean but that would require a new board washer as our current washer doesn't have seperation and is closed loop. I know many of you will say I need to run my own testing and I will but I am looking to narrow the field of candidates.

Your help is greatly appreciated.

Good Afternoon,

We are using Kester 520A. It has worked well for us so far.

Good Luck

Chris

Hi,

Why is no-clean and rf not considered to be a good process?

Some NC gunk is somewhat prone to raising a ruckus with rf circuits. Here's a smattering of info. re: that. It's been discussed and is present in the archives in a number of threads.

So I take it no one is doing this or they don't want to share their secret recipe ;-)
