There are a few excellent resources for you to help you design, build and specify rigid flex and multilayer flex circuits. Best of all they are free!
The first is a book called “Flexible Circuit Technology” written by Joe Fjelstad. It is available at www.FlexibleCircuitTechnology.com, or by clicking on the picture to the right.
Saturn PCB Design, Inc. has produced an electronic designers toolkit, with many helpful features built in, including impedance modeling. You can get your copy for free here.
The IPC has a guide to help you design rigid flex and multilayer flexible circuits. It is called IPC 2223 – Sectional Design Standard for Flexible Printed Boards.
If you’d like a free copy of the IPC 2223, fill out the form below and we’ll mail it to you. The IPC 2223 can also be purchased online at www.ipc.org
