Metal-Based PCB

1.Multi laminating aluminum-based PCBs / Soldering technology to cooper-base PCBs fulfill the needs of better heat radiating on multi-layer PCBs;
2.Buried magnetic core technology for metal-based PCBs with metal laminates in the middle enables heat radiating and also small size integration;
3.The technology of partially buried copper fulfills the needs of cost saving, small size integration and high radiating;
4.The design capability of concentric circles in metal base PCBs enables the isolation between fix holes and PTH holes in those PCBs;
5.The integrated coursing technology in metal base PCBs ensures the high reliability between metal base and epoxy resin or hydrocarbon laminates.
