  Solder paste may look like a small part of the SMT assembly process, but it can have a big impact on PCB quality. If you are thinking about solder paste shelf life, this guide has got you covered.  From poor printability and inconsistent deposits to soldering defects, expired or improperly stored paste can quickly lead to costly production problems. Understanding solder paste shelf life and following the right storage and handling practices can help manufacturers maintain consistency, reduce waste, and improve assembly results. Maximising Solder Paste Shelf Life: Essential Tips for PCB Assembly How to Store Solder Paste to Maximise Its Shelf Life Store it in a refrigerator: Keep solder paste at the manufacturer's recommended temperature, typically around 2°C-10°C. Avoid freezing: Don't freeze solder paste unless the manufacturer specifically recommends it. Maintain stable temperatures: Avoid frequent temperature fluctuations, as they can affect the paste's consisten...
