Interconnect Solutions for Flexible Printed Circuits and Etched Foil Heaters
One of the most common questions our Applications Team receives is, “what is the best way to mate with a flexible printed circuit (FPC) or etched foil heater?” This is a difficult question to answer as every application is unique, because of this some interconnect...
All Flex Announces New President and CEO!
Northfield, MN. All Flex is excited to announce that former Chief Financial Officer, John Fallon, has become the new President and CEO. John has been serving All Flex in the CFO role for the past two-and-a-half years, demonstrating a high level of commitment to All...
Thermal Simulation to Optimize Flexible Heater Designs
Application: Using thermal simulations to reduce cost and design to production time. Most often when designing heaters for new applications the designer knows the desired outputs and has created a 3D model of the application. What is usually unknown is the amount of...
LDI for Flexible Circuit Etch Resist
This article is the third and final part of methods for imaging etches resist. The first part discussed screen printing; the second part discussed traditional photo exposing. The third part discusses laser direct imaging (LDI).The basic process sequence for LDI is...
Flexible PCBs and Connectors
While a well-designed flexible circuit will eliminate many connectors, ultimately most flexible circuits need to connect to something. Probably the most common entity that a flex circuit connects to is a rigid printed circuit board, but cable harnesses, polyester...
Plating Process Options for Flexible Circuits
Plating copper through holes or vias is a requirement for double sided and multilayer circuits. In a previous blog we discussed the plating process; specifically copper seed coating using electroless copper and shadow® plating, which is then followed with an electro...
Copper Thickness Requirements for Flex Circuits
There are many reasons an end user will specify the copper thickness of a printed circuit. The most obvious reason would be for current carrying capacity, but copper thickness also directly impacts thermal performance and impedance. All these are vital properties...
Vias and Through-Holes in a Flexible Circuit
I heard one of our Applications Engineers describe our product as “making sandwiches”. It is a pretty good metaphor as it helps visualize a cross section of a printed circuit with several layers of dissimilar materials. Most flexible circuits and PCB’s have multiple...
Cost and Price of a Flexible Circuit
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...
Flexible Circuits vs. Printed Circuit Board
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,...
