High Current Pcb Design Tips

The resistance of copper traces and vias account for significant power loss and heat generation in pcb based devices especially when they carry high current density.

High current pcb design tips. Electrical connections with a larger cross sectional area have lower resistance which reduces the amount of power lost to heat. As your traces are carrying higher currents the amount of damage to components and the board is greater. For example high voltage circuits may require components that have higher breakdown voltage ratings and the capability to handle higher currents. High current pcb design tips.

Your design should be based on high current rules and not those typical for lower weights. As with any circuit the primary concern with a high current circuit is ensuring that it operates safely. High voltage pcb materials and design for arc prevention ensure the final product is safe and functional. Pcb materials and design for high voltage.

Why it is important. The main hazard is heat. Carrying large currents on the pcb requires some design modifications and rules. Pcb design rules must follow manufacturer guidelines for not exceeding values that can destroy the devices.

There are a few potential issues that are unique with boards that drive such high powered loads. Heavier copper for higher currents. When creating a pcb for high voltage dc bias standards and precautions become much more stringent. Avoid increased costs and danger by keeping these pcb materials and design tips in mind.
