Hi Sean, No-clean flux does leave a residue. Under the best conditions, it is invisible. There are many factors that can cause the residue to become visible such as an inadequate oven profile (or lack of proper preheat on a wave). Also, if wave s

Hi All, I have some question about flux residue resulted from non clean process as following: 1) Under what kind of circumstances that flux residue could appear? This residue does not happen during production but did appear after some period of ti

Using no-clean flux going thru wave when comes out there is a bit of flux residue left on board. If wiped the residue shows a yellowish tint. Any ideas what this means how to get rid of it?

Dear Sean Contrary to believe MOST formulators of No Clean fluxes or No Residue fluxes use organic acides that are in fact weak and benign. IF the residue was left on the board and you had a condensing atmosphere then you may see some issue with fal

i am working with the noclean process and getting white residues on the bottomside of the board probably due to the wave soldering flux.i am using a no-clean solder paste and a noclean wave solder flux.The boards passed the accelerated temperature a

Sounds like a rosin flux. Is it sticky as well? Russ

Using Interflux IF2005, Have electrovert as well as new Novastar Topside of board temp is 265F solder bath 275c. I assume applying via foam fluxer. Not sure.

We agree with Russ. Your topside should be 100 - 130*C. Your 265*F is at the top of the range. Look here: http://www.interflux-electronics.com/Products/Fluxes/IF%202005M/TD%20IF%202005M.pdf#search=%22Interflux%20IF%202005%22

Hi Steve, What type of flux? How do you apply it? What kind of wave? Rite off the cuff, I'd say you're applying too much flux, but without knowing a little more, it's tuff to say. It could even be board related. Hate to see what WML has to say
