Nettet6. apr. 2024 · Most printed circuit boards have drilling holes. Many kinds of holes are described below:Older PCB technologies mainly support lead assemblies that require one hole per pin, called “through hole” or “PTH” (plated through hole) technologies, but more and more modern technologies use dense surface mount components. Through holes became plated-through holes (PTH) in order for the components to make contact with the required conductive layers. Plated-through holes are no longer required with SMT boards for making the component connections, but are still used for making interconnections between the layers and in this role are … Se mer In electronics, through-hole technology (also spelled "thru-hole") is a manufacturing scheme in which leads on the components are inserted through holes drilled in printed circuit boards (PCB) and soldered to … Se mer Axial and radial leads Components with wire leads are generally used on through-hole boards.
