Designing flex circuit has its own challenges that you need to consider when you are laying out a circuit, calculating impedances, or selecting material. While our engineers can walk you through all of these challenges we can also create the designs for you. FIT has several design solutions to offer our customers based on your unique needs.
Application Engineering: We have engineers on site to discuss your project, it’s applications and your overall needs. Through this complimentary service we make suggestions and advise on the best solution path to ensure your design is a success.
DFM: Through our proprietary DFM software we filter out any design rule violations that would hinder manufacturing. Our software is programmed to detect design errors against our specific manufacturing processes. DFM report provided upon request.
File Conversion Services: PDF, DXF, and other non gerber formats are acceptable to convert into a universal gerber format file package.
Design Analysis: We are looking for constraints and stresses in your design that may affect the integrity of your flex. CAD software cannot detect all of these issues and we assign an engineer to your design for review. You cannot rely solely on automated software to detect issues in a flex, it must be reviewed by a human.
Layout Services: We have staffed engineers have decades of experience designing flex and rigid flex printed circuits. One of the advantages of having your fab house also design your flex circuit is we know the unique challenges flex brings to manufacturing. This can lead to a reduction in up revisions and free up your R&D money for other product lines!
Our engineers will layout your design in Allegro and Altium. When you take advantage of our premium layout services we will provide you with custom gerbers, fabrication print, BOM, drill file and CPL in a universal format.
100% Guarantee: Your success is our success and when we partner with you on a layout your satisfaction is our number one concern. Once the files are complete our engineering team will send to you for review. We will address any requested changes at that time, modify, then send you final files for approval. We do not bill you until the files are 100% approved.
Bend Radius Rules
|Type Of Flex||Minimum Bend Radius|
|Single Sided Flex||3x to 6x the thickness|
|Double Sided Flex||6x to 10x the thickness|
|Multilayer Flex||10x to 15x the thickness|
|Dynamic Flex||25x to 40x the thickness|
