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.

Are there profilers that I can use over my leaded and lead-free wave that can also profile my reflow ovens (leaded and lead-free). I'm not that familiar with either but as I learn I can't help but think that there should be something on the market t

We're soon to build a lead free assembly with 0201 components. I'm not worried about placement as our machines can handle it. Any tips on printing, screens, reflow?

Hi. I am trying to understand Tg and how it relates to reflow. With the higher temperatures of lead free, we have been looking toward laminates with a Tg of 180 instead of the current 140. My question is a little more general. In either lead free

Hey guys, Anybody having trouble with increased false contact issues in ICT after switching from lead to lead free? Our test guys keep trying to imply that the flux residues are a problem (we're using Alpha EF2202), but as the soldering process eng

I agree! I am using a SAC305 no clean from Alpha. I have noticed that even hand probing with volt meter leads requires me to press very hard on the pads to bust through the flux residue.

So just to clarify.... If i bought a KIC 2000 I could run that one unit over both my waves and through both my ovens (leaded and lead-free)? Or would I need additional equipment to use it on the wave?

We have a board that uses 0402x4 RNET packages that we are having a difficult time getting to solder consistently. Paste deposition is fine (using AIM WS353) and profile is dead-nuts. I'm starting to wonder if this is something that we're just goin
