Flexible Circuits and Man-made Satellites

August 18, 2017

The first satellite was launched by the USSR in 1957.  The US successfully launched its first satellite, Explorer 1, in 1958 while announcing the intention to “win” the race to outer space Source. Today satellites serve a number of vital purposes.  They are used for telecommunications, weather observation, global navigation,...

Flexible Circuit Failure Analysis

August 16, 2017

Design reviews and early involvement by a circuit board fabrication house can minimize the possibility of field problems but, despite best efforts, there remain occasions when diagnosis of a poorly performing design is required. These instances occur most frequently in applications with unique performance requirements (mechanical abrasion, unique bending, and...

Using ZIF Connectors with Flexible Circuits

August 6, 2017

Zero Insertion Force (ZIF) connectors are probably the most popular flexible circuitry connector because they allow the circuit to be inserted and removed multiple times with very little mechanical wear on the copper traces.  ZIF connectors are designed with a mechanical latching mechanism that clamps down onto exposed traces to...

Flexible Circuits and Flexible Heaters used for Reusable Medical Products

August 3, 2017

Flexible circuits have been used in medical devices and medical instrumentation for several decades.  Flexcircuits and flexible heaters can be ideal solutions in applications requiring light weight, continuous movement, and highly reliable interconnections that are biocompatible. Recent material advancements have expanded the realm of flexible circuits to include applications in...

The Anatomy of a Flex Circuit Cutline

July 10, 2017

In a previous article we discussed the various methods of creating the cutline of a flexible circuit.  With the various tooling options the methods, process steps, tooling and technology are different. These differences affect the actual “physics” of cutting, and create slight variations on the circuit material. In most cases...

Trends in the Electronics Medical Industry

June 30, 2017

The US medical electronics has been one of the fastest growing industries over the past decade. Similar to the rest of the electronics world, growth has been accompanied by the adoption of significant new product technology and innovation.  The need for a high level of control, reliability, and confidentiality has...

ITAR Registration

June 23, 2017

Like many vendors that build product for the defense industry, All Flex is ITAR registered.  ITAR stands for International Traffic in Arms Regulations and is a program run by the US government to control the export of defense related technology to foreign countries. ITAR regulations require information related to defense...

Successful Flexcircuit Assembly

June 15, 2017

There are a key differences between flexible pcbs and rigid pcbs requiring alternative design rules and handling methods.  One general area that is often a particular concern occurs when flexible circuits require component assembly.  Many contract manufacturers are reluctant to mix rigid and flexible circuits on the same assembly line...

Button Plating on a flexible circuit

May 18, 2017

Button plating describes a fabrication process widely used in the flexcircuit industry to selectively electroplate copper to the vias and onto the pads capturing the vias. The rest of the copper traces do not have plating.  Another industry term used to describe this feature is “Pads Only Plating”. Producing a...

Back bared flexible circuits

May 6, 2017

Back bared pad flexible circuits are a distinctive type of single sided flexible circuit providing some advantages over more “standard” circuits.  In the printed circuit industry, back bared pad circuit designs are also referred to as “dual access” or “reversed bared”.  As their name suggests, these circuits have insulation openings...
