Manufacturers involved in critical product cleaning may be aware that the U.S. EPA may ban or highly restrict the sales and use of n-propyl bromide in manufacturing. The EPA is interested in the impact on small businesses including costs and performa

In section 7.3.2 of ANSI J-STD 001 " Drying / Degreasing states the assembly may be treated to remove moisture and other volitiles" I have contacted one board manufacturer who states that it is recommended to bake a board to remove volitles. Are

I have heard of this but do not have direct experience. Immersion tin is susceptible to moisture absorption particularly after washing off solder paste. So it sounds like your boards are picking up the solvent off the screen. Water rinse or degrease

You can try using the brand-solvent "Genesolv 2004" in conjunction with a degreaser machine(source for own machine type?). this all helps to clean off the NC flux. we used it all integrated together, to clean a satellite modular card. reason we ha

Dear Adam, Yes, today certain companies are still using this cleaning technic to clean assembled PCB's. To be able to give you the right advise, I need to know what kind of fluxes are you using into your soldering processes and what level of cleanlin

We pull our chains and fingers off of our wave and take them down to Carquest autoparts store and have them soaked in an engine degreaser. The then re-lube the chain and re-grease the rails when we first put the chain back on. This is the cure that

We use Kester 186 flux and the STU people would sometimes find white residue after cleaning with Isopropyl at the solder station. We have Lenium (Petroferm)in our vapor degreasers, and now they use Lenium at their stations as well as final clean, an

We need to clean the RMA flux residue on the PCBAs. The PCBA material is ALuminum base(Gold finish)stacked with Rogers Material PCB.Any solvent recommnedtaions? Is HCFC 141b a good solvent (quality & Price). we need to use vapor degreaser and also do

We already have contact with Zestron and we try several chemicals and process (Immersion, aspersion, vapor degreasing). And we always find something under low standoff component. Concerning the flow pressure and shadowing, we try different position

As a side note: A lot of machine manufacturers call out IPA as a "degreaser". As an experiment put a dab of grease in a container with IPA then put some in a container with mineral spirits. Shake them up and see which one dissolves the grease. It's
