Does anyone have any experience with cleaning debris, removing oxidation from ICT (or for that matter flying probe)probes: Regards BWET

As with noclean flux, OSP will fill your probes with crunchy [maybe gummy] stuff. Consider: * Increasing frequency of probe maintenance * Talking to your probe supplier about alternate probes that self-clean better

That's what I guessed. Some ideas to consider are: Reduce usage of flux to the bare minimum. Choose a low solids flux Flux residues can be categorized as soft, brittle, sticky but this depends mostly on the formulation of the flux and the resins

Yes, no-clean is more of a challenge, particularly for halide-free no-clean. Requirement on probe testability will make it more difficult.

For the better part of my career, I've battled with ICT guys on so-called "flux residues" on their test probes, and this was when using NO-CLEAN, 2% to 5% solids tops, flux. People don't understand that ICT probe maintenance is an inherent part of

Are the tin/lead ratios compatible betweem HASL and wave solder? Probably are, just a remote possibility. Flux application is? bubbler, sprayer? Either way, are you getting good misting, coverage on those teeny 0.5mm test points? If not, then no

I do not expect that we will see increased residue volumes, but they may be a bit more difficult to remove (in a cleaning process). A related issue is probe-testability. We can expect, at least initially, that there will be higher defect rates asso

On the flux reside issue that is gumming up your test probe pogos ... Short term, clean what's in process with a aerosol flux cleaner solvent. Ask your flux supplier for recommendations. Longer term, recognizing that there is no fix, your improveme
