Yes pads are still gold after the wave soldering process even if you wave solder a pcb several times. I have tried soldering using an iron and the solder takes to the pad as you would expect. This happens on all boards of this type and all boards are

Measured the pot temprature independantly from the software (268C/514F from moving wave). We are using Dross Inhibiter Tin/P Regenerator from BLT. Monthly sample checks are carried out on the solder bath and are all within limits. It will be hard to

Hi Folks, My Production runs a uBGA-liken product, and uses Pallets to support the 0.8mm thick pcb, during the SMT + reflow oven process. Process/QA see occurs: 1) 0402 unsolder? 2) 0402 tombstone? 3) "uBGA" poor-visual joints (dry joints)? Took
