I have experienced this directly in SMT and wave solder. Fillet lift (can) be a direct indicator to lead enrichment (but its not the exclusive symptom). Lead enrichment in smt joints reduces the interfacial strength shortening the time to creep f

Hi everybody, We have wave solder fixtures made of Durapol and multiple wave solder machines. Most likely we�ll use the same pallets for either tin-lead or lead-free solder for a while (of course after washing the pallets). Should we test the palle

My policy is not to mix them. You have zero cross contamination potiental with this policy.

I don't think that you would need to test these. Have you ever seen any evidence of solder sticking to them? We use the same material and never notice anything besides flux staying on the bottom. Would the lead absorption if any even be of a concer

MF300S is quite an old flux, & a lot has happened since then on the flow solder front - are you sure it's designed for Lead free, or is it just a traditional flux that SHOULD work OK with Lead free?

Is the flux rated for lead free? These higher temps will cause most lead rated fluxes to burn off prior to the wave. Jerry

Hi, I am experience problems while testing wave soldering SMT components that are glued on the solderside (lead free). Between de leads of SOx type IC's and SOT's develop a great deal of solder beads. I have been using a RSS temp.profile while spr

Thank you all for your input. The MF300S Multicore flux is rated for lead free. There is not much dross or contamination. We are using nitrogen. I've tested the boards with the curing test of IPC-TM-650. I think you're all right about the preheat.

Wave and Press-Fit fixtures

Hi everyone, I am looking for a reliable company (preferrably on the west coast) that can make Wave Solder and Press-Fit fixtures for our back-plane division. I need a reliable source that can take our data and produce quality fixtures in a 5-7 day
