Using Flexible Circuits as an Electronic Interconnection – Do’s & Don’ts
August, 2011 – by Dave Becker, All Flex V.P. Sales & Marketing
Flexible Circuits are proven, reliable interconnect solutions for many of today’s electronic packages. This article gives some general guidelines in terms of “dos” and “don’ts” that will help the engineer or designer make better decisions when using flexible circuitry as an electronic interconnection.

This requires a close working relationship between supplier and customer and is best accomplished with an intimate understanding of the application and customer expectations. Learn about the All Flex continuous improvement program that supplies intensified customer support during initial design and delivery – tailored to a company providing custom engineered products.

Very few circuitry suppliers are good at everything; rather, they tend to develop a specialty. You want your supplier to have a developed capability that dovetails with the requirements of your product .There are five critical considerations to keep in mind during the selection process so you can make an informed decision with confidence.

As the drive to reduce space and weight while adding functionality at a reduced cost continues, flexible circuitry is fast becoming an ideal interconnection and packaging design solution for this industry. This growth can be expected to continue, challenging product designers to get ten pounds into a five pound bag.

Dr. Ken Gilleo, PhD – a recognized industry expert of flexible circuitry, electronic materials, and electronic packaging. A prolific author of over 500 articles and 8 books including “Handbook of Flexible Circuits and Polymer Thick Film”. Dr. Gilleo is a productive inventor in circuitry holding over 30 US Patents and was awarded the Atomic Giant 2000 – one of the most influential people in the printed circuit industry.
