FLEXIBLE & RIGID FLEX PCB CAPABILITIES
As an ISO9001:2015 certified leading prototype-to-production Flexible PCB Manufacturer, we have manufacturing capabilities of flexible printed circuit board, Rigid-flex PCB and HDI Rigid-flex PCB that other companies cannot complete with. As your flexible circuit supplier, you will be able to build boards with trace width and spacing down to 2/1.6mil and 3mil micro vias. In any stages of your FPC board project from layout to Gerber files convert, you can consult our front-end engineering team for cost-down with the optimal technologies. We offer quick turn flex circuit prototyping service and mass production service. Our FPC board and high-density rigid flex board capabilities also support 12-layer multilayer flex circuits fabrication. View our flexible and rigid-flex PCB manufacturing capabilities below.
