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

Hello! I need some help! Does anyone know marking pen that is water soluble? I want to wash off marker in a cleaning machine using only hot water. I tried many different type of water soluble marking pen, but it did not come off easily.

| i had a problem here, during the wave soldering process, we apply a water soluble mask on the gold finger to protect it from contamination. But after washing, there is still some mask left on the gold finger. | Can anyone pls advise is there any pa

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

Is it possible to have a no-clean flux that could be removed with water. I would like to use a single flux at wave solder that could satisfy both no-clean and water soluble customers, within a contract manufacturing environment. Thanks, Tim A.

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

It realy depends on what no-clean you use, I had on that would get under IC's and not get fully activated it was fine here in the states but when it was shipped over seas the salt air and humidity gave us fits, another we used didnt have that problem

Ahhhh, Dave, I'm glad I can still count on you for some real cutting edge info. yuck, yuck. Believe me, there's a lot more information available on how to resolve no-clean issues than there is on how to keep this stupid board wash/DI/Stencil wash/

Awww Stevo, just chill. I think of NC as the process engineers' full employment material. Water solubles are for wimps!!! Har har har
