More than Just a Heater Flex Fabricator

June 19, 2018

When All Flex first entered the flexible heater market, it was primarily a “build to print” fabricator of flexible heater foils.  The initial success was due to All Flex’s industry-leading rapid response and quick turn capability for both small and large volume production. Today, while All Flex still maintains that...

Flexible Heaters: Different Heater Designs, Same Wattage

June 9, 2018

Jahn Stopperan, All Flex   Producing a flexible heater with a defined wattage can be accomplished in a variety of ways. The images below all represent a heater of the same wattage designed to operate with different voltages.  Typically, OEM designers define the wattage of the heater, its overall shape/size/configuration,...

Flex Might be the Lowest Cost Solution

June 3, 2018

In most cases, if one compares the cost per square inch of a flexible circuit with that of a PCB, the later comes out lower.  PCBs in general are less expensive to process; use less costly materials and their processes are easier to automate.   However the total cost of an...

What Happened to QS9000?

May 2, 2018

When viewing our certifications page, one will see that All Flex is listed as being QS9000 compliant.   The reason for this is that QS9000 is no longer an active certification where an auditor reviews you system and grants certification.  QS9000 compliance indicates that our systems would meet the requirements if...

Cost and Price of a Flexible Circuit

March 26, 2018

In the right application, flexible circuits can reduce wires, eliminate connectors and rigid circuits. They might also simplify component assembly and reduce wiring errors. But competitive products such as rigid circuits, wires and connectors also have their place in the interconnection packaging world. These substitute products all can offer cost...

FAQ’s on UL Listings for Flexible Circuits

January 25, 2018

Most electrical consumer products in the US have a UL (Underwriters Laboratory) listing, which means that the product meets certain safety standards.    In some cases it may be a requirement for a product to be UL listed, in other cases it becomes a sales and marketing decision.   UL requirements are...

Design and Construction Features that Can Cause Trace Fracturing in a Flexible Circuit

January 22, 2018

Flexible circuits are used in applications requiring millions of flex cycles. But this does not suggest they are indestructible. In fact, occurrences of performance issues as the result of fractured traces have been experienced in a variety of applications. Solutions are often the result of design, construction, and feature location...

Copper Grain Direction

December 15, 2017

Many materials have different characteristics depending upon the orientation of the material.  For example woven textile materials have a warp and a weft direction.  The warp direction is the longitude direction and the weft is the transverse.   The cloth will behave differently depending on which direction the tension is applied. ...

Polyimide vs. Silicone for Flexible Heaters

November 21, 2017

Our last blog post “Options When Purchasing Flexible Heaters” provided an overview of a few options when specifying a flexible heater circuit.  In this article we would like to continue with that theme, with a focus more on the insulation materials that can be used. Backing up a bit, we...
