The problem with super glue is that is has a cyanide base that turns into a toxic gas and evaporates when heated. See IPC-7095. Via's should be fully plugged with solder mask at the fab house. If your PCB designers are not up to speed on IPC requi

| I was wanting to know if double sided reflow can be done with a metal plated BGA on topside. We would be running bottom side first. My boss seems to think the only way it can be done is by placing glue dots on the bottomside compoents because the

I have come across a rash of failed assemblies that have 0805 capacitors and resistors, bottom side glued, wave soldered and washed. Trouble shooter reported touching up the solder joints on a few areas and the boards would pass test. I had a look a
