Rigid flex pcb design HDI staggered vias and stacked vias Stiffener| YMSPCB

Short Description:

For more than 11 years, YMS PCB have developed expertise in Flexible and Rigid-Flex Printed Circuits Manufacturer for most application sectors, including HDI designs, in small, medium and large volumes. Although Flexible and Rigid-Flex solutions can provide an optimal technical response to all 3D applications, they remain somehow a costly product, mainly because of high-value material (polyimide), variety of stack-ups and complex manufacturing.

  • What is flexible and rigid flex PCB

    As the names suggest, a rigid PCB is a circuit board built on a rigid base layer that cannot bend, while a flexible PCB, also called a flex circuit, is built on a flexible base capable of bending, twisting and folding.
