  • Question: What do I do with the unused portion of a container of solder paste?
     
    Phil Zarrow: The key thing here is to store the solder paste properly. So what we want to do is to keep the solder paste container closed. If it's a cartridge, keep the cap on it. If it's a jar, replace the lid. And the other important thing is to store it in ambient. Do not re-refrigerate it, because you risk having condensation forming and having an adverse effect on the solder paste.
     
    Question: Can I keep using solder paste that's already been on the stencil?
     
    Phil Zarrow: No.
