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 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

| 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

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

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

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

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/
