Excerpt: The Printed Circuit Designer’s Guide to…Flex and Rigid-Flex Fundamentals

June 20, 2018 | Dave Lackey and Anaya Vardya, American Standard Circuits

The design process is arguably the most important part of the flex circuit procurement process. The decisions made in the design process will have a lasting impact, for better or worse, throughout the manufacturing cycle. In advance of providing important details about the actual construction of the flex circuit, it is of value to provide some sort of understanding of the expected use environment for the finished product.

Faster Board Speeds Demand Constraint-Driven Design

Using powerful constraint techniques can be a double-edged sword. While the design process is made much safer by including constraints, it is all too easy to over-constrain the design and make it impossible to complete routing and placement. Even paper design guidelines can make products uneconomic to produce unless a great deal of engineering knowledge is applied during the design.
