Hi, I am currently using a peelable mask prior to wave soldering and have started exploring water soluble/washable masks. The mask will be used with water based and alcohol based flux. Are there any compatability issues to concider and how will this

Steve, Water-soluble fluxes are per definition very corrosive and need to be cleaned (read the data sheet) Encapsulation will prevent humidity reaching the water-soluble acids but will not prevent reducing the metals the flux is in contact with to m

Rather than cleaning a water soluble flux residue off the board, by encapsulating the product. covering the board or the component with lets say a Hysol encasulant. Would this prevent the active flux residue from migrating and deteriorating the elect

I work for an R&D company that is starting to do some prototype and limited production circuit cards. We are deciding how we want to build these boards, and we are wondering what we should do about flux and cleaning. We have circuits that run at 15

Davef is right on as usual. We are doing exactly what you do. Some smt with no clean paste then the plate through connectors on our selective solder machine using water soluble flux. We then clean with a ultrasonic water process. We do see the re

Hi Dave, Water soluble flux has two opposite attributes. #1: It is the easiest flux to remove. #2: It is the worst flux to leave behind on a board. As for # 1, there are many de-fluxing systems out there that are very capable of removing water

Mike -- Thanks for the information. It is very helpful. Is there any information available that shows what flux most companies are using? What fluxes are most companies that are producing Space, MIL-Spec, or other high-reliability assemblies usin

In the following thread, http://www.smtnet.com/electronicsforum/view_message.cfm?message=9584& John Thorup touched on some applications where no-clean fluxes could be a bad idea. I'm looking for some more detailed info. (papers, references, texts

I use a water soluble flux to solder an LCD into gold plated through holes of a .031 circuit card. Problem is the current water soluble flux (850-33) is not made anymore (the drop in replacement has a different formuala and does not work). The main i
