Q1. Do we really need to follow the IPC J-STD-001 Solder purity? A1. Yes, you should control impurities in solder. Further information: * "Allowable concentration of contaminating elements in solder: impurities are harmless unless their level goes to

Surface tension is a likely cause. Surface tension is a negative wetting force. You may have a solderability problem. Be sure your flux is properly activated according to the flux mfg. top side board temp. specification. When surfaces to be soldered,

Doug, Have you tried running the boards at an angle to the wave of between 15 - 30 degree's ? I've done this on a few boards to eliminate short's and I believe it will work on your problem very sucessfully. Best thing to do is get your wave solder c

Dross formation rates for SnCu and SAC are roughly 2.5 times the rate for SnPb (Hwang et al., 2004) Methods for reducing dross are: * Lower pot temperature * Run pump speed slower and only when soldering * Check solder contaminants to BS219, ASTM

I am an equip mfrs rep. I took a customer to my wave solder principal's factory to run their boards on a wave with no-Pb alloy, (Sn96.5 Ag3.0 Cu0.5) in air environment. The results were excellent with pot temp of 263C (505F). Their boards are low to

I am trying to put a center support on a wave solder machine for lead free soldering. My problem is that every metal I use is interacting with the lead-free metals and thus eating away the center support. I have tried titanium, stainless steel. I am
