Hi C.K. , You can ask your PCB manufacturer to cover all vias with solder mask from CS (It called "pluged" vias). It's done from one side to prevent any close area that can cause "eraption" of solder because of pressure under reflow. All our boards

For ICT purposes I may need to print solder paste on 0.015" test vias. No-clean is not an option for this assembly and OA seems the only choice. Can flux be safely removed from inside the via from the other side during a standard water wash process

The temperature that will melt solder holding top side SMT components during wave soldering depends on the alloy of that solder. So, for example, you'd expect: * Near eutectic SnPb solder to melt around 215*C. * LF to melt around 240*C. It's common
