Hi...i am a new user here. Does anybody know how long after I apply solder paste to a board I have before it goes bad and can't be reflowed? I've read about printing and abandon time but that's related to the stencil, and see numbers for things lie overall shelf life, but can't find out how long the paste is good for once it's on the board.
I've got to make 15 boards that take about 40 minutes each to populate (384 SMD components) and am trying to plan out if I can print, print, print, place, place, place, bake or if I need to print, place, bake, print, place, bake, etc.
