In my experience there is no need for wet wiping stencils. We run 0201'and micro BGA's daily with no issues. If you are having paste release issues, I would be looking at other things. Aperture area aspect ratio, aperture design, land design, sold

Hi experts, I asked our chinese board manufacturer about their recommended procedure to clean miss-printing. The answer was that they use Absolut Alcohol while use IPA currently and we are moving to a water based cleaning agent with ultrasound. Th

it is not that big deal. you can use almost any generic grease. I use SKF bearing grease on CP45FV's. Just make sure you remove old grease, I use IPA and compressed air to do this. And don't put too much of it or too little. After greasing everything

I have modules that come with a 4 x 2 pin header. The problem is the pins must be oxidized as they do not take solder (no wetting occurring). This occurs whether solder in our wave soldering machine or soldered by hand. I tried cleaning the module i

The hardest part was convincing management of the need for a stencil cleaner in the first place. Cleaning by hand using IPA and a lint free cloth just leads to clogged apertures and print defects. BTW, lint free cloths leave behind a lot of lint.

Hi, Mainly concentrate on 2 subjects: 1- Cleaning of Misprinted PCB (always use best neutraliser to remove paste from PCB), 2- Underneath Stencil Cleaning - Use good stencil cleaner (rather than IPA) to wipe your stencil. Because both the above said

I am looking to replace some spray guns that I have been using for a few years that are no longer reliable. You can see them in the attached picture. Does anyone had a brand/model that they would recommend? Any info or advice would be greatly appreci

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

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

I only inhale flux with a high IPA content.(joke for those who don't know me) I have seen the inside of duct work for our wave soldering machine............NASTY! DAVE F. is right! Flux contains a lot of bad stuff- Chlorides, Bromides, Flourides,
