Many thanks for the name check from John Thorup PIHR can be done very simply and it can provide positive fillets on both sides of the board. I have just finished a line with SDSRS, Simultanouse Double Sided Reflow Soldering thats sodering both sides

Phil Zarrow published a paper on solder paste test methods a few years ago. Check his site: http://www.itmconsulting.org We have no relationship, nor receive benefit from the company referenced above.

I agreed not to ask the shelf life extension to the maker of solder paste. However, somtimes we have no chioce except using expired or used paste. When I have to, try the first PCB as a test. If Ok, just carry on other boards. Unless, use a new solde

We have a new site that is in the process of starting up and doesn't run much (1 tube every couple weeks). They recently called me about using expired paste. I told them to print a few scrap boards and run them through SPI to verify good print and

Does someone with technical knowledge knows what exactly happend with the solder paste after the shelf life pass? What we have seen is sometimes flux separation which disapear after a good mix, and change of viscosity i.e. drying. The tin, silver and
