I don't know about Universal GSM, but for my Mirae's nozzles I use IPA and small US-bath.

Agree, PVC tube with a screw on cap at one end. we store in IPA though, cleans it and keeps it from drying out.

Hi All We are looking for not expensive solution for misprint PCB cleaning for both one and double side assemblies. We have tried different ways and cleaning solutions like: IPA, Vigon Zestron SD300, Vigon SC200 by deep the boards in to stainless ste

We manufacture a low cost machine completely Air driven for Misprints only but dont have an agent in the USA unfortunately or could have demo'd it for you They do work very well with IPA derivative cleaners but IPA on its own is very poor. Best metho

But soon after cleaning and drying with IPA, we find a white residue formation. A: IPA will not nothing to clean your board. The white residue is exactly what you should expect. Search the fine SMTnet Archives for background. >How do we avoid th

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

Density is an "implied" measurement to determine activity. Most flux suppliers can sell you a flux acidity (activity) measurement kit. I used one from Multicore a few years back. We used it once in the morning and once after lunch to monitor no-clean

Grant, No-Clean paste + IPA = White Residue! #1: Stop using IPA #2: Switch to either a solvent-based de-fluxing chemical or an aqueous-based de-fluxing chemical. If you are using an ultrasonic cleaner for your boards as stated, do not use sapon

You're correct. Operators shouldn't be doing "touch-up". [No value added] Take that as your clue for areas to improve process. Babbling about touchup: * Left to itself, touchup feeds on itself, operators are parinoid that inspectors will "ding" th
