Aqueous Cleaning PCB's with Potentiometers

It's not acceptable to us. More importantly, you need to determine if it's acceptable to your customer. Recognize that your little IPA scrub does NOT remove the OA flux residues from the board. It mearly spreads them out across the board and under c

Upinder, Using IPA does not cause the residue, it simply exposes it. Given that all fluxes leave reisdues, it follows that these MUST be benign - but how do you know, and how do you control it. You are using flux to remove oxides and give you a go

Cleaning after rework, no clean flux

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

Necessity of ROSE in commercial quality processes

Hi, just my comment, theoretically No Clean means no Ion Contaminants from Flux, but it some some case ion contamination (Cl-Br-F) could come out from raw PCBs, from Components, from fingerprints, etc. To incorporate a ROSE step in the pro

Hi John, Are you talking about cleaning the pallets after running to store them? or during production? well in any case...I recently started to use this cleaning solution "Cybersolv" from Kyzen. It is water soluble and also can be used instead of IP

Cleaning a No Clean

There is a lot of information available about cleaning no-cleans. Takes chemical, mechanical and thermal energy. Find the right chemistry for the flux (not something like IPA that will most likely just smear the residues around and cause problems

Hi GS, Just a clarification� No-clean does NOT equal no ions. It equals less ions (at best). Automatic R.O.S.E (Resistivity Of Solvent Extract) testers are commonly used to detect ionic contamination from no-clean applications. Your comment rega

Problems with IPA are: * IPA / material being 'cleaned' combination still needs to be removed from the board. * IPA and empty containers are a hazardous material by RCRA criteria (40CFR 261) * Flash point (~12*C TCC) of IPA is low enough that all ele
