Flex and Rigid-Flex Circuit Assemblies

FAST-TURNAROUND MODELING AND PROTOTYPING Design and Production Process

GLENAIR INTEGRATED PCB/FLEX ENGINEERING

From Concept to Design

The mechanical schematic design process typically takes one of two forms: either the customer presents a fully-realized mechanical design, or as is often the case, the process begins with a “napkin sketch” of the project. Here is an example of just such a rough design that kicked off a rigid-flex circuit assembly development process.

Glenair engineers utilized our Altium software to create a functional and problem-free mechanical design for customer review and modification prior to starting the build.

Electricals : The next step is to define the electricals. To approximate layer count, we need a wiring diagram “schematic” complete with signal types, currents, and shielding requirements. This is also used to determine ROM pricing. In this project, work to this point was completed in just 3 weeks. With the final design approved, we were ready for production manufacturing.

Validation test requirements : Glenair offers complete generation of PCB/flex fabrication data packages including component-level documentation. Most flex customers specify validation testing as a required part of the documentation package. Tests may include DWV/IR, continuity, impedance (eye pattern), and others.
