This product is a 1.5m extra-long & large-size PCB. Custom processing of large panels is available, multi-layer structures can be fabricated with various substrate and copper weight options. Strict control of panel warpage and overall dimensional accuracy ensures stable wiring on extra-long boards. Precision circuit and hole machining are supported, with a full selection of surface finishes. Featuring good heat resistance and insulation performance, the boards have excellent flatness to minimize assembly deviation. They are suitable for industrial large PCBs, equipment backplanes, PV inverters, large power supplies and large lighting applications. Custom production is available upon request.
