(All PCBs are custom-manufactured. Reference images and parameters may vary based on your design requirements.)

Hi, I’m Sally from Bicheng Technologies Limited, and today I’m here to introduce one of our high-quality PCB products: the Double-Sided Flexible Polyimide PCB. This PCB is designed for applications requiring flexibility, durability, and precision, making it ideal for industries such as automotive, computers, mobile devices, and office automation equipment. Let me take you through the details of its construction, features, and applications so you can better understand its capabilities.

1. Overview of the Double-Sided Flexible Polyimide PCB

This double-sided flexible PCB is built using a flexible polyimide base material and features a yellow coverlay solder mask on the top side. It’s engineered for applications where flexibility and reliability are critical.

With a finished flex thickness of 0.22mm and 2oz copper weight on both outer layers, this PCB ensures excellent electrical performance and mechanical stability.

The PCB also incorporates PI and FR4 stiffeners, which enhance structural integrity in specific areas where additional support is required.

The combination of flexible polyimide and ENIG surface finish ensures high-quality solderability and corrosion resistance. This design is compliant with IPC-Class-2 standards, and every board is subjected to a 100% electrical test before shipment.

2. PCB Construction Details

This PCB’s flexible design allows it to be folded, twisted, or bent without compromising its electrical performance, making it suitable for compact and dynamic devices.
