Good morning! I'm sorry to hear about the anomalies you're experiencing with your inline wash. Dealing with foaming issues can be challenging, but I'll do my best to provide some suggestions to help you troubleshoot the problem. 1. Check the Water Q

Hello I have the problem with selective soldering on the robot. Thin balls appear on the laminate. The tin sometimes shoots...? and then the balls are a few millimeters from the soldering point. I tried up or down with temperature, but it did not wor

I mean...there are a ton of possibilities for bridging on selective solder before you ever get to alloy purity. Are the bridges happening consistently in the same spot? Are the leads too long? Can you modify the approach/exit/peel off to address? Wh

We are using Mulicore MF101 flux and a Vitronics selective soldering machine on a lead-fee assembly and are having trouble with nozzles blocking even when the nozzle aperture is increased. Has anyone come across this problem before using fluxes with

Do you have clear picture show how it looks like solder open? And you can run DOE with TAL and soak time and peak temperature to see which factor is key, or non of them is key then you can try add some flux to see if better before change solder past

Hello All, We have a small selective solder machine from RPS, a Rhythm SS, purchased used with SN100C in pot. For a couple of years we have used this machine and gotten good results. We have been adding SN995 to the pot as it needed more solder. Then

Tell us about: * Temperatures and times of the thermal profile * Where the thermocouples were mounted * Materials involved * Where in the process the 672 BGA component is soldered * Processes that follow that soldering

Depending on the design, materials selection, end use, etc; we'd expect the FIT of an electronic assembly to be between 30 and 100+. There is no standard.

There is no such standard, nor should there be. BIG boys [and girls] solder products like this. What temperatures are you measuring on the terminations of these components?
