We have a double sided pcb
that is surface mount on both sides. Now a Through Hole connector has been added. Appart from hand soldering does anyone have info. on reflow soldering the part. The connector is 0.1mm pitch, square legs. 1) Do you need to change the hole pad, shape. 2) Do you apply paste from both sides of the pcb, at each printing stage. 3) Do you need to use solder pre-forms 4) Do you need to use jigs to prevent the solder being pushed out when the connector is inserted.
