Pattern design, paste volume,printing misalignment, place misalignment,reflow process include N2 usage. All the factor above can make tombstome happen. And the most important factor is placement misalignment except design issue. But pls check the sol

Has anyone come across a standard or study (JEDEC, IPC) where it has the recommended shelf life outside of a dry box for immersion silver coated PCB's to prevent oxidation from affecting the soldering process (Both reflow and Wave). I know it will
