Through-hole technology
MOUNTING SCHEME USED FOR ELECTRONIC COMPONENTS THAT INVOLVES THE USE OF LEADS ON THE COMPONENTS THAT ARE INSERTED INTO HOLES DRILLED IN PRINTED CIRCUIT BOARDS AND SOLDERED TO PADS ON THE OPPOSITE SIDE MANUALLY OR BY AUTOMATED INSERTION MOUNT MACHINES

Through-hole technology (also spelled "thru-hole"), refers to the mounting scheme used for electronic components that involves the use of leads on the components that are inserted into holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side either by manual assembly (hand placement) or by the use of automated insertion mount machines.
