Semi rigid flex PCB as a cost-effective alternative
$32.80
Semi-flex PCBs are made of thin FR-4 material that allows limited bending in specific areas. They are suitable for applications that do not require high flexibility but do require a certain degree of bending ability. Compared with rigid-flex boards, semi-flex PCBs are a cost-effective alternative with lower costs and simpler manufacturing processes.

Questions & Answers
1.How can I receive a quote for my order?
Simply complete our online quote request form or contact our sales representatives by email or phone with your project details.
2.What design files should I submit to get a quote?
We require Gerber RS-274X and NC Drill files. Kindly compile all relevant documents into a single .zip file for upload.
3.What is the difference between semi-flex PCBs and flex PCBs?
Semi-flexible boards offer limited flexibility, allowing bending in specific areas. Flex PCBs are fully flexible and can be bent or folded without cracking.
4.What are the advantages of semi-flex PCBs?
Compact design: Semi-flex PCBs can be bent or twisted to suit the complex space, achieving a compact design.
Improve reliability: They offer higher reliability due to better resistance to vibration, shock, and harsh environments.
Affordable: They cost less than flex PCBs, as flexibility is achieved by milling FR4 instead of using costly materials.
