In assembly the bare board is populated with electronic components, called a "printed circuit board assembly" (PCBA). In through-hole technology, the component leads are inserted in holes surrounded by conductive pads; In surface-mount technology (SMT), the component is placed on the PCB so that the pins line up with the conductive pads or lands on the surfaces of the PCB.

I have 15 very large backplanes (.156" thick Au plating) that the ground pins of a high density thru-hole connector were not thermal relieved in the artwork. As a result we are unable to solder the 8 pins that connect to the ground plane. We know the design is at fault and will correct this for the next build. In the mean time I need these boards and have run out of ideas. We have tried different solder types, wave solder, hand solder every trick we can come up with and no success -- we can not apply enough heat to the board to get the solder to flow. Any ideas would be appreciated. We are even considering a conductive epoxy
