Ok, maybe I'm missing something here: It's a no clean flux type AND your going to wash it? Why not migrate to OA Flux and just run DI water with Ion-Exchange beds? Benefits: No need for ultrasonics No need for chemical isolation No need for cleani

We are having issues with solder flooding some through hole pin receptacles which have an organic fiber plug on the soldering end. Anyone else use these types of receptacles and soldering with selective solder. Appears the plugs may be not sealed w

The last statement saying that seeing down the bga component with these systems is useless, is an incorrect statement. First with x-ray you do not see flux residue and or flux migration, second with x-ray you do not see a cold solder joint. Visual i

What type of flux are you using today? - Obviously you have already outlined the difference in the parent materials and parent material preparation, so using the same program/profile will not work; the characteristics are different. Try increasing p

This is one of the most common questions I get asked. Why clean no-clean flux. It was stated earlier that no-clean residues are benign. This may or may not be accurate. It depends on several factors including the reflow process. In a perfect world, t

We are having metal migration issues with SOT 223 and TO 220 parts runing at 500V DC. We are using no clean flux and suspect that is causing the problem. Does anyone have any experience with these levels of DC voltages or know of any consulting firm

Looking for any reliability data on aqueous flux residue causing low Z defects, specifically any data that may illustrate life expectancy under any humidity/temp environment. How long it takes for conductive material to migrate and form low Z impedan

Hi, We dealt with and solved this problem here at Agilent...We have been doing simultaneous reflow cure in convection reflow ovens for all of the 9 years I've been here with minor problems of chips falling off, and after switching to Loctite 3609 th

Obviously, if your customer instructs you to use a certain flux type, using THAT flux type is probably a good idea. Responding to your question: Chloride is one of the more detrimental materials found on printed circuit assemblies. Chlorides can com

What is the surface finish of the PCB? Tin? Imersion Silver? What flux is used in wave solder and / or SMT? I have much experience with silver migration and tin wiskers. Both can disappear during a reqork cycle. Both can be extremely difficult
