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.

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

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

Dear proffessionals! Question is about this alloys - Sn99Cu07 and Sn100 (Sn100C,Sn100Ni+ etc.). Is it O'k to mix them? In my case to use Sn99Cu07 as addition to selective soldering machine bath with Sn100C? Main components are the same, but minor add

Hello Mark, I wish it were that simple so I could direct you to a particular manufacturer and stencil cleaner model. Unfortunately, there are several issues complicating the process of cleaning all these applications in one machine. First and fore

You didn�t tell us about your solder, wave temperature profile, or the distribution of the problem. So, let�s assume the solder is near eutectic and the problem is wide spread. Wolfgang makes good points. So, let's talk a different tact. When we
