Circuit boards with a high mix, high technology, and high quality are our main areas of concentration as PCB manufacturers. For example, we provide 2L-36L rigid-PCBs, HDI and stacked microvias, high-speed and low-loss boards, heavy copper, rigid-flex & flex circuits, metal-backed PCBs, and RF microwave boards.Sunshine Global Circuits is an expert in assisting clients in moving complicated designs from prototype to mass production. Impedance modeling, material recommendations, stack-ups, and DFM advice are all provided by our engineering and FAE group. In order to make sure that every project is optimized for cost and manufacturability, we are eager to share our knowledge with board designers.
