I would like to hear from anyone who has had experience using Alpha NR310 no-clean flux in their wavesolder operation. We are having difficulties controlling residue levels on boards. Thanks.

This issue is not "testability of OSP board". It is "testability of nc flux residue". Kester [or some other flux suppler] can probably recommend a flux residue that is more probeable. We have talked about the problems with probes getting gummed-up

We do have a commen problem with flux residues after the wave soldering process, even after using correct wave soldering profiles recommended by the flux supplier, The following flux type is being used Alpha EF 2210 VOC Fre Bellcore No Clean water Ba

I'm using a lead free solder paste, low residue from SENJu among all the pastes I've tried it is the best I've found. you can ask for any type of alloy, but request the 729C flux type. kind regards

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

Will the flux residue from solder paste A come into contact with flux from solder paste B? If so you better do some tests. There is always a possibility of a bad reaction between 2 fluxes. You need to test to make sure. Jerry

For what its worth. Even though you are potting the boards. If for whatever reason flux residue (OA) was left on the board prior to potting this flux could migrate and cause embrittlement problems with the solder joint. I would definately inspect for

Even though this is a "no clean" flux, are you (or the customer) cleaning the boards? If this is truly a low signal level device, there is no way you will get away without cleaning the flux residue. I do a lot of low-level hardware, and we have to

Hi, we are about to change solder paste for cost issue. Currently using a no clean Sn63 solder paste and tried several others, all no clean, Sn63 and Sn62. Want to ask about reliability test: we did thermal shock test for 8 days. The flux residue cha
