Solder paste is a material used in the manufacture of printed circuit boards to connect surface mount components to pads on the board. It is also possible to solder through hole pin in paste components by print solder paste in/over the holes.

Hi Folk's,
a quick and easy? question. Got a card with PTH edge stiffeners fitted to it so we need to flow solder them. Having problems getting hole fill, mainly I think due to 2 things, poor pin to hole ratio and also a bit of oxide. The question is how do these fit into IPC 610C in term's of hole fill requirements. I Think that it just fall's into the same as a std PTH hole and need's 75% min (class 2), one of my collegues say's that it doesn't matter as its non electrical so isn't covered by IPC 610 C, I can't believe this is correct, anyone got any opinions?
