What’s with the expiration dates on solder paste or wire? Accept or Reject: Solder Contacting Component Bodies Issues of Burnt Flux on Class 3 PCB Assemblies Gold Removal Issues with Hollow Cup Connectors Have a question about training or IPC certification
: We have a through-hole integrated circuit (IC) component that has good wetting when it goes through the wave soldering machine, and the solder climbs pretty far up the lead

+125oC for 5800 cycles. It was observed that ENIG surface finish improves the component reliability comparing to OSP and ImAg. It is also observed that matching solder sphere with solder paste alloys improves the reliability in several cases, but a significant improvement was not observed when compared with the SAC305 solder spheres

. Through hole paste reflow can benefit using solder bricks to increase joint volume and decrease flux residues. Some placement machine suppliers offer produced cut and form feeders, so solder wire is used, reducing the cost of simple preforms Back in the day the presenter used preforms with vapour phase and
