. Reflow solder joint formation process 1. First of all, the solvent used to achieve the required viscosity and screen printing performance begins to evaporate, and the temperature must rise slowly (about 3°C per second

. So why not make the pad shape match the stencil. Here are lead and lead free solder after reflow. There is no solder in the pad corners
