You can test for solder paste tack using IPC-TM-650 method 2.4.44. This will give you an idea of the adhesive strength of your paste prior to reflow.

This has been a problem with new components coming directly from vacuum sealed desiccant packed moisture barrier bags with moisture level cards. We have also baked all boards prior to the BGA rework to ensure no moisture issues were addressed.

I have had the same problem with this supplier, we found that one mfg. place or process used a .015" piece of FR4 as the base while others had .030" Fr4, We discontinued use of the .015" and never had a problem again.

Could you not just switch to alcohol based flux? If your prob is getting the water off the board prior to hitting the wave, maybe you could install some type of convection to aid in this? Russ

HI again Dave, I was wondering what kind of problems you were experiencing with the silicone tape that led you believe that it wasn't the correct tape and question the manufacturer? Were there more failures and solder issues ? Thanks

Glynn We allow no silicone in our shop, because it ruins solderability. For more look here: http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=47025

Can you do it? How much is going to cost? How long it is going to take?

We believe your problem is caused by the mismatch in CTE of the material ised in your BGA. In fact, this "potato chipping" [where the corners curl-up] is present in all BGA. The issue is the matter of degree. [Mismatching CTE is how old thermostats
