Hi, I would also be interested in this thread, but our problem has a different twist to it. We have good results from our reflow with Koki no clean paste, however when we pass the boards through the wave solder machine, the flux in that leaves a fog

Hi Patrick, With all due respect, it is easy to quantify zero. You made a claim that your flux produces ZERO residue. There are several industry-standards (IPC and Military) of determining the cleanliness of post-reflowed circuit assemblies. Th

Hey guys. I've been manually dunking circuit boards for 8 years now. I too have the excess residue issue to contend with. I'm using a low solids - no clean flux from Kester (959). I have used solvents, thinners, windex and a multititude of cleane

Hello Dave, I hope that electronic slap didn�t hurt too much. Robf, I am sorry that you did not agree with my initial response, but the answer is very detailed and most of the support material I have is only in paper format so I need to either snai

I am a PCB Designer and I have to put a note on the assembly drawing to tell the assembler how to clean the board. This is new to me. Here is a sample note. Can someone give me some feedback on it? "Use water washable, no clean solder paste for t

What is the best or ideal cleaning method for wave solder pallets? I have been using iso prop and am not sure if this is the cause for having brittle wall material. I wouldn't think alcohol would degrade the durastone material. Most of my pallets hav

thanks for your reply, actually we bake the PCB assembly prior the rework because the package was exposed for quite some time already. The baking time was 24hrs @ 125 deg.C. We notice that there were flux residues on the connectors after the baking.

There are chemistries out there that will solublize some post-solder NC flux residues. I have had success with Zestron material Vigon A200 and Petroferm material Hydrex DX. Go to http://www.zestron.com and http://www.petroferm.com These are chemical

We don't own one, I'm a bit interested to see what you end up with. We do have a triden pcb wash, and I know Aqueous Technologes makes a lineup of misprint and stencil cleaners. We had an engineer in from Zestron chemical company, and while they don
