I am new to wave soldering. Any information is greatly welcomed. Here is the problem. After soldering the boards they have a film on the bottom of them and sometimes a white powder looking substance. I have tried decreasing the amount of flux on

Hey all! The wave solder warrior is back. I have found a flux which leave almost no residue (the least yet), but because of its super low solids content I absolutely cannot get topside fillets. The multi-layer, two sided board is on a pallet w

1.) Are there any industry white papers written that document any advantages in running this alloy? From what I've read, this alloy was formulated to prevent leaching of silver for silver-bearing component terminations. 2.) Are there any concerns w

Sn62Pb36Ag2 has a higher liquidus point of 189C as compared to Sn63Pb37 at 183C. You may need to slightly adjust your oven profiles to use it compared to SnPb. We have had good solder-ability and reliability with it in our IPC Class II products. A

| This question is directed to anyone having eperience with Sn62Pb36Ag2 solder balls for BGA's. | Have you seen anything like a rough, raisin-like surface texture after ball attach? If so, what did you do about it? | | Thanks! | Jenna: We've used

I assume you are talking about Sn62Pb36Ag2 solder. You should not see any added concerns when subjecting Sn62 to multiple reflow cycles as compared to Sn63. As compared to Sn63Pb37: Reduced leaching issues Increased Wetting due to lo

I think SEHO GoWave 1030 is better than ERSA ETS 330. The SEHO GoWave 1030 is a powerful soldering system for mass soldering applications. It's used for all types of soldering.
