What is Heavy Copper PCB?
Heavy copper PCBs or thick copper PCB are defined by structures with copper thickness over 3oz. These PCBs are used for high power as well as optimization of thermal management applications. The thick copper permits huge PCB-cross-sections for high loads and also encourages heat dissipation.
For PCB production, copper weights 1, 2, 3oz are the usual options, which are good for the low power wirings however can not satisfy the high-power requirements, specifically in power as well as auto electronic devices. In recent years, along with the demands, copper thickness enhances swiftly, reaching up to 20oz (called extreme copper).
PCBANow can 1-12oz heavy copper PCBs, we had actually made lots of heavy copper PCBs in the past 15 years, which offered high performance exceeded assumptions, and benefited our clients.
