Flex PCBs
OFFER
3 main types of Flex PCBs
Unlike rigid PCBs, they allow flexible adaptation to different shapes and applications.
At BERATRONIC we offer three main types of Flex PCBs:
Type1: Single-sided flexible PCBs (IPC-6013):
They are available in variants with and without stiffeners.
Type 2 Double-sided flexible PCBs (IPC-6013)
We also offer models with and without stiffeners.
Type 3 Multilayer flexible PCBs (IPC-6013)
This variant comprises a top layer on both sides of a glueless FPC construction with three or more conductive layers and metallized through-holes.
Our manufacturing expertise extends up to four layers, also with the option of stiffeners.
Their great advantage lies in their adaptability to complex shapes and space restrictions, which enables the development of compact, lightweight and reliable electronic devices.
BERATRONIC stands for outstanding manufacturing expertise and customized solutions in the field of Flex PCBs.
FAQ
Answers to the most common questions about Flex PCBs
1. What are flex PCBs and how do they differ from rigid PCBs?
Flex PCBs are made from thin, flexible materials such as polyimide or polyester. They can be bent, folded, or shaped into complex geometries. Compared to rigid boards, they save space and weight while offering greater design flexibility.
2. What advantages do flex PCBs provide for modern electronics?
Flex PCBs enable compact assemblies, reduce overall weight, minimize the need for connectors, and are more resistant to vibration and movement. They also improve thermal management and enhance overall reliability.
3. Which industries and applications use flex PCBs?
Flex PCBs are widely used in smartphones, tablets, wearables, medical technology, automotive electronics (e.g., sensors, lighting), aerospace, and industrial equipment where space is limited or moving parts are involved.
4. What materials and constructions are used in flex PCBs?
Polyimide is typically used as the base material, copper is applied for the conductive traces, and protective coverlays or flexible films replace traditional solder masks. Stiffeners may be added in specific areas to provide extra mechanical support.
5. How is a flex PCB manufactured?
The process involves laminating copper onto flexible substrates, structuring the traces by photolithography and etching, applying coverlays, drilling or punching vias, shaping outlines by laser cutting or routing, adding surface finishes, and performing electrical and mechanical testing.
6. What challenges do flex PCBs present?
Key challenges include maintaining the minimum bend radius, ensuring via reliability under repeated flexing, resistance to environmental influences, and managing higher production costs and handling complexity compared to rigid PCBs.
