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 the component and the PCB, beneficial for long-term reliability. Read on as we discuss through-hole pad design.

Copper Current Density in PCB Design

Copper Current Density in PCB Design

Copper current density refers to the amount of continuous current going through a copper wire —whether on a circuit board as a trace or not. According to the principles of Joule or Ohmic heating (represented as VI or I²R), any material that conducts electricity will generate heat, leading to a gradual rise in temperature in both the conductor and its surrounding environment.
