High power heavy copper PCB
The primary benefit of heavy copper pcb boards is their capability to survive frequent exposure to excessive current, elevated temperatures, and recurring thermal cycling, which can destroy a regular circuit board in seconds. The heavy copper PCB board has a high tolerance capacity, which makes it compatible with applications in rough situations such as, defense and aerospace industry products. Some of the added advantages of heavy copper PCB boards are:
- Compact product size due to several copper weights on the same layer of circuitry
- Heavy copper-plated vias pass the elevated current through the PCB and assist in transferring the heat to an outer heat sink
- Onboard high-power-density planar transformers
Heavy copper PCB is not a new innovation, as it has been used for a long time in PCBs that can withstand the exacting requirements of military and defense applications, such as in weapons controls. Mainstream electronics makers increasingly require ways to transfer heat away from components, and heavy copper pcb is becoming more prevalent in an growing number of non-military uses.
Many designers and assemblers do not know what is readily available in high current heavy copper PCB. Heavy copper pcb boards can contain 3 ounces to 40 ounces of copper conductors. Quite surprisingly, a heavy copper PCB (10 ounces heavy copper pcb) can also have very fine features.
