All Flex Certifications and Standards Compliance

March 28, 2014

At the bottom of our capabilities and certifications page, one will see a list of global standards to which All Flex has demonstrated compliance.  The standards include: ISO 9001: 2008 AS9100:2009 MIL-P-50884E ITAR IPC 6013 IPC J-STD-001 UL ROHS QS 9000 JCP The following is a brief explanation of each...

Printed Circuit Boards vs. Flex Circuits

March 21, 2014

The terms flexible printed circuit boards and flexible pcb’s are often used to describe the products that we design and fabricate. Technically, these phrases are not entirely correct; although most of our customers that use these terms all looking for exactly what we build.  In fact, when someone first approaches...

RoHS Compliant Flexible Circuits and Assemblies

March 13, 2014

Many flexible circuits are assembled into products that require RoHS compliance, and therefore must also meet specific standards.  RoHS stands for Restriction of Hazardous Substances, it is a standard adopted by the European Union in 2006.  Its purpose is to reduce the life cycle impact of known toxic materials.  These...

The US advantage over China in Flexible Circuits

March 3, 2014

Currently 42% of PCB fabrication and 29% of flexible circuit fabrication is in China, with about 5% of the FPC market in the US.  This is largely a reflection of China’s dominant consumer manufacturing industry. Products like cell phones, cameras, and other personal computing devices are built in quantities of...

Selecting a Flexible Circuit Supplier

February 27, 2014

The following is an article written by Dave Becker, VP of Sales and Marketing, All Flex Flexible Circuits.  The article originally was published in PCB007 in October of 2013 Selection of a supplier for a flexible circuit is a multi-dimensional decision. Searching the internet produces a long list of suppliers...

How to avoid trace fracturing on flexible circuits

February 18, 2014

How to avoid trace fracturing on flexible circuits Flexible circuits are ideal for applications that require bending and twisting.  This flexibility gives designers options that are not available with the typical printed circuit board.  This does not mean that a flexible copper trace will never crack, as like most metals,...

Coverlay Adhesive squeezeout on flexible circuits

February 10, 2014

Most flexible circuits require a dielectric layer that insulates and protects the conductive traces, while exposing pads used for component attachment or terminations.   Dielectric openings may need to expose a group of pads when there is not enough room for individual openings. Circuit with Coverlay or Covercoat There are a...

Soldering to Flex

January 27, 2014

Flexible circuits (flex, flexible pcb, flexible printed circuit board) and printed circuit boards (pcb, hardboard) are usually populated with electronic components to perform their desired functionality.  Soldering is the most common method for populating components.   While the basic processes are very similar, the material set differences between a printed circuit...

Printed Circuit Board vs Flex Circuits

January 24, 2014

It is common for many designers and engineers to think of a flexible circuit as a printed circuit board (PCB) that can bend.  While it is true that a flex circuit and PCB perform the same electrical function, the structural and mechanical differences are significant, and not understanding them can...
