One thing I've found that will create that white residue is when moisture comes in contact with that flux. 1. Verify that you are not introducing any moisture with the compressed air supply at the foam fluxer. 2. Replace the flux and clean the flu

Dear Adam, Yes, today certain companies are still using this cleaning technic to clean assembled PCB's. To be able to give you the right advise, I need to know what kind of fluxes are you using into your soldering processes and what level of cleanlin

Thank you PWH, All good points. I use a semi-automatic printing process not a screen printer so if more solder balls and beads are created then I would be creating more re-work and that is exactly what I do not want to do. I guess the best thing to

Hello All, Has anyone tested the effectiveness of any process to remove lead from tinned soldering irons to RoHS acceptable levels? We have been dedicating new tips for RoHS assembly, but as our RoHS product line increases it will be important

Hi Russ, Can you please clarify on what you mean by "after wash they should be gone since it is water soluble,".....the flux would be water soluble or otherwise, how does that relate to solder balls being removed by cleaning?...i can see them being r

We are in the early stages of converting al of our customers to No-Clean solder. I expect some customers to have no objections, others I am sure will be concerned about the "residue." I know that chemistries have improved greatly and if the process i

If you find the correct type of adhesive/needle size then dispensing certainly is no problem. With a footed needle a very repeatable process too. Much more flexible than stencil printing and no need to mess around with stencil cleaning. But with auge

-Are these lint-free rags ESD-protected = yes, must be. I left that out thanks! -How do these lint-free rags remove the flux that seeps under components = no matter its a no-clean material and we are removing for esthestics only. -Have you considered

No i didn't move any cable just cleaned the old grease and applied a new one, also checked the tension of the belts and cleaned the inside of the machine. In any case no cables where moved at the maintenance process. And the only info i have is the

I guess my question would be why are you getting so much/leaving so much flux on the boards during the select solder process? With a drop-jet fluxer you should be able to apply the flux very selectively and leave a fairly clean looking PCBA, assumin
