Demand for heavy copper PCB in Electric automotive, computer, industrial controls, and military is growing very fast. More than 80% of the existing printed wiring board manufacturing is limited or not capable of producing reliable heavy copper printed circuit boards.
The driver behind the demand of heavy copper core PCBs is ever increasing power requirements in power products and the elimination of complex wired buss configurations. Hitechpcb has been associated with heavy copper pcb plating since 2000 and we have good quality on it.
Heavy copper PCB – General specification
In PCB industry for thick Copper core PCB or Heavy copper PCB people generally use the name to identify a printed circuit board with copper thickness more than 3 Oz in inner or outer layers and extreme heavy copper PCB refers to more than 15 Oz printed wiring board.
Thick copper board technology offers the possibility to implement complex switches in limited space in combination with circuitry for high current levels. Multi-layer PCB has reliable processes to produce copper layer thicknesses up to 20 Oz .
Heavy copper PCB normally used for high power rectifiers, Computer, military, Electric vehicle charging, power grid switching system, etc.
