Flex Circuits, RIGID-FLEX Capabilities
A Flex PCB or FPCB is a patterned arrangement of printed circuitry and components that utilizes flexible based material with or without flexible coverlay. These flexible electronic assemblies may be fabricated using the same components used for rigid printed circuit boards, but allowing the board to conform to a desired shape (flex) during its application. Experience cutting-edge solutions with Precisio PCB, your top-tier partner for flex and rigid-flex PCB manufacturing in the USA.
From quick-turn flex to rigid-flex circuits or any PCB type, our capabilities, equipment, and expertise ensure your needs are met. Benefit from flex circuit services for PCB layout, fabrication, and assembly, tailored to your requirements. Contact us today for flex circuit parts for your products.
