Plated through hole technology
Webb30 aug. 2024 · In the past, components with long leads would be inserted, usually by hand, into plated through holes on the PCB. The leads would then be soldered to form permanent interconnections with the holes. This was known as through-hole assembly. Through-hole PCB with 14-Pin DIP. Lead spacing for DIP is 0.100” x 0.300”, with 14 holes and … WebbWith plated through holes there is a conductive path from one side of the board to the other, as seen on Figure 1. EXTENDED DEFINITION: This technology was extensively used in PCB Assembly during the 70s and …

WebbThrough holes are traditionally divided into plated (supported) through holes and non-plated (unsupported) through holes. “Supported” refers to the plating on the hole wall. Unplated or unsupported holes may or may not have pads, such as mounting holes and non-porous wall plating.
