The Immersion gold is not a problem with BGAs specifically but "black pad" which can be present anywhere. The unfortunate thing with BGAs is you cannot see it. Personally I hate white tin. It is okay for single sided boards running no-clean, but c

Where could I find more information regarding the double sided reflow and flux problems with white tin?

I have heard that there are problems using immersion gold on PCBs when working with BGAs. Is this correct? Is white tin more suitable?

We use SN100C for wave soldering and hand Lead free soldering and have had very good results. The wire cored solder for hand soldering flows good and makes very good solder joints. The SN100C in the wave solder machine also works very good. We use

As converting our boards to lead-free finish (Immersion White Tin) we decided to change de mask color from green to blue. We thought this would be a good idea to spread the idea so we could easily recognize the type of solder application related to t

What's the metallization on the board? We use an immersion tin board and had to increase our profile to successfully solder.

Our customers use OSP, HASL, immersion tin and immersion gold as board finishes. If I recommend a finish to the customer, it is one of the immersion finishes or OSP. Those finishes have the advantage of a flat surface to deposit paste. HASL has va

I predict you will have no problems with your soldering. Remember that all plating is only a few microns thick and quickly washed away by the molten solder. We have used white tin, immersion gold, OSG, etc. for quite a while with leaded solder and
