Just about to set up a lead free solder pot exchange system for my Electrovert. Wondering if anyone has had success using say large ball bearings or materials which will sit inertly in the bottom to occupy space and reduce the alloy required without

I am experiencing a problem with a surface mount coax connector that over time pulls loose from the PWB. The connector has 4 small gold plated leads and we are soldering it to a flash gold board. A cable plugs into the connector and puts some const

I have seen an issue that escapes our ICT and functional testing or operates in an intermitent fashion. The lead is slightly separated from the PCB with a fully formed solder joint behind it at the heel an toe. The joint apears to have started to tra

Ken, You nailed it! We have a Electrovert Vectra wave solder machine that will erupt solder all over the place while heating up, we had to disable the timer because of all the solder splatering. Electrovert told us that our machine had a small des

| After switching from No-clean flux to Water soluble (Kester)we encountered voids problem (X-ray and microsectioning). Reducing the apperture sizes made the voids smaller but did not eliminate them. So we had to go back to No-clean. Any idea why voi
