What is a through-hole in a PCB?
A through-hole is a type of connection point on a printed circuit board (PCB), which allows electrical signals to pass through the board and connect different components or circuits on the opposite side. Here is an explanation of the different types of through-holes found on PCBs. 1. Soldering Through-Hole (SOT) Soldering Through-Hole (SOT) is a type of through-hole that allows electrical connection between two conductive pads on the same layer of the PCB. These pads are typically soldered together using surface mount technology (SMT). The through-hole allows the solder to flow between the two pads, forming a solid connection between them. 2. Through-Silkway (TS) Through-Silkway (TS) is a type of through-hole that allows electrical connection between two different layers of the PCB. It typically involves drilling a hole through the board and then using a conductive material, such as copper, through hole PCB to fill the hole. This allows electrical signals to pass through the board
