The chain and fingers for our Wave solder is getting a large amount of residue from the flux (high dissolved solids) we are using. Any recommendations for products that can clean polymerized flux.

Thanks for the information. davef, I will search for and review the Ion Chromatography for Ionic Cleanliness test method. This definitely is the test I want to perform. Do you know what the IPC specification is using this test method? The outside

Here's what I've seen for no-clean flux applications: Leaded: Dwell Time is? 2 - 3 seconds Top side board temp max? If some small SMT parts reflow are we too hot? 110 to 120C top side board temp just before hitting the wave(s) Pot temp. 245C Lea

Questions are: * Does the component take solder when you dip it in the solder pot to test the solderability of the leads? * Can you get full barrel fill when wave soldering a bare board? * Is your flux reaching the top of the board through the hole b

We are currently applying solder bumps to hundreds of BCC's for rework. It is impossible to print to the PWB. It is recommended to apply solder bumps to the BCC's with 63/37 alloy making the rework faster and easier. Applying the solder bump on the

Currently, in my working factory, we facing the flux residue remain on connector after washing. (of course, this is clean process with WS solder paste). So, are there any ways to clean the flux residue rather than go back to wash again? Because wash

HI My board house has asked us to change to E TIN 34 Solderable Immersion Tin we curently use Hot Air Leveling, we do SMT & thru hole and use no-clean flux. If anyone out there knows any thing about E TIN 34 Solderable Immersion Tin good or bad I wou

I haven't worked with Protecto but I have seen very good results using a no-clean flux and a nitrogen atmosphere in the reflow oven. | Entek or Protecto? | I've hear Kester's Protecto is a very good OSP that may be more assembly process-friendly th

We have noticed that when you are using a no-clean flux with the wave solder process that you will have additional solderballs. One thing that we have done is to change the PCB finish to a matte finish. This has greatly reduced the number of solder

Hi There: We have a wavesolder m/c with foam fluxer. I want to know: - When we do not run the machine, how to keep the fluxer porous cylinder in a good condition? knowing that we use no-clean flux. Is it the same when we stop for a few days or wee
