Through-Hole Pad Design: Enhancing PCB Durability and Reliability

In printed circuit board (PCB) design, the choice of pad type plays a critical role in determining the durability, reliability, and performance of the final product. Through-hole pads, which are designed for components with leads that pass through the PCB, offer superior mechanical and electrical connections compared to surface mount pads. This article explores the design steps for...

Through-Hole Pad Design for PCB Durability

In printed circuit board (PCB) design, copper pads are points for attaching components with soldering. These pads come in two primary types: through-hole and surface-mount (SMD). Through-hole pads are designed for components with leads that are inserted through the pad’s holes and soldered on the opposite side of the board. This method ensures a mechanical and electrical bond between...
