If I had to deal with this problem, I would switch to water soluble paste. It is a much more cost effective solution.

Hi, We use IPA and Prozone, if IPA is so drastically detrimental, to the pcba's.....what suggested alternative, can you please recommend, as IPA replacement? Thanks.

We have customers that are requiring no flux residue left on boards after soldering of non-water washable parts. We currently use Multicore Crystal 502 No-Clean to solder parts that are not washable. Has anyone come up with a good way to remove this

This is a real problem. We have experimented with a number of off the shelf products as well as discussed the issue with a few solder manufacturers. As you are aware IPA or Flux off can make the product look worse. I would discuss with the custome

saturation occurs at ppm levels. Remember, IPA is extremely flammable and its bulk use makes the plant liable to all sorts of quite repressive safety rules/regulations and so on. Ignoring these rules exposes the owner to fines and possible plant cl

Hi Jeff, Sean is correct. Although ultrasonic technology will work in post-reflow de-fluxing applications, you will receive concerns regarding ultrasonic �damage� to wire bonded components. Much has been written to combat this belief but the conce

Hello Jeff, If you have components on your board be careful of how low the frequency is that you will be applying to your board. Ultrasonics are great for cleaning stencils and bare boards at around 40kHz. These frequencies (and Lower)may however

Hi, I curently have an interesting challenge. But I don't have all the knowledge to solve it. One of our boards is used in RF applications. We noticed that the No-Clean flux residue makes interferences in the RF signal. Removing the flux residue so

Acetone is likely not compatible with several component types, the evaporation charactoristics are desirable. IPA is more compatible, though, may not solubilize the residues. Austin American Technology developed MegaSolv JB and MegaSolv NOC for the

we noticed Electroytic caps (Rubber plug), standoffs, and most of the plastic and rubber parts were effected and started to break down. I do not know id the mask material is effected or what residue is left behind ....as we never made it past the 1s
