Holes Used in PCB: Through Hole

Through Hole, also known as perforation or through-hole, can pass through the entire PCB board, from top to bottom, and is used for inserting and connecting components. Through Holes are mainly used to insert pins or connectors into the holes to provide stable electrical connections and increase mechanical strength. Through Holes are suitable for applications that require high strength and reliability, such as industrial equipment, automotive electronics, etc. Through Holes are generally mechanical holes, but laser holes are used for through holes of Any Layer Interconnect.
