OK all you Gurus here's one for ya. Customer is tinning wires with standard eutectic solder in a solder pot. There is a blue tint to the solder in the pot. After tinning with OA flux, which I will change to NC shortly, he has clear teflon insulation

This phenomenon is caused by a high amount of halogens (Cl, Br etc.) used in the flux activators or in the flux surfactants. We've seen effects creating all colors of the rainbow. Changing to No-Clean (halide-free) will eliminate this color effect.

Patrick told you why, But here is some more info for ya, I would absolutely not recommend that wires be tinned with OA. The residue will never get cleaned underneath the insulation and all of your strands will strt to break in the near/far future.

Thank you both for your assistance. I knew that I could count on you folks. The customer has purchased No-Clean flux and is using it as we speak. Hows that for customer service.... All in a days work... Thanks again You make me look good!!! Steve

We have a problem with our Unleaded wave solder machine only randomly soldering some pads. I have looked at the flux level and that appears fine aswell as cheking the preheat and solder height in the bath. The probelm is not exclusive to one perticul

Measured the pot temprature independantly from the software (268C/514F from moving wave). We are using Dross Inhibiter Tin/P Regenerator from BLT. Monthly sample checks are carried out on the solder bath and are all within limits. It will be hard to
