  • The way to stop the bottom parts falling off during reflow is to put the board in a tray of talc powder. The powder supports the parts and the board, so there is no place for them to fall.
    With this technique, you can stencil, stuff, and bake the top surface, flip it, stencil and stuff the bottom surface, and then put it in talc for the second round of baking.

No public wish lists :(
