Balancing the Electrical and Mechanical Requirements of Flexible Circuits (.pdf)
is required, the nominal value is typically 50 ohms (100 ohms differential). Achieving. these values in a flex or rigid-flex circuit usually requires thicker flex substrates than those required for a flex. circuit with no impedance requirements. Also, the layers that require impedance control must

Soft grip overmold takes the abuse
substrates range from 25 to 1,000-ksi flex modulus which spans the mechanical performance range of polyolefin, polycarbonate, and "wet" nylon. Parts can be overmolded by two-step or two-shot injection molding, insert molding, or simultaneously by coinjection molding. The letter opener

Guidelines for Bonding Plastics
the joint, they are invisible within the assembly. Adhesives resist flex and vibration stresses and form a seal as well as a bond, which can protect the joint from corrosion. They join irregularly shaped surfaces more easily than mechanical or thermal fastening, barely increase assembly weight, create

Staying flexible
. You'll get the straight info on what does or, sometimes more importantly, what doesn't work. The dynamic nature of flex circuits results in a multitude of design options. One method for determining the validity of a design is to physically create a flexcircuit mock-up. When producing a mock-up

Part Design Guidelines for Pulse Heated Reflow Soldering (.pdf)
This report will cover the process definition and components used in the pulse heated reflow soldering process. We will look in depth at the component part design criteria necessary to achieve the optimum quality and consistency of a flex to PCB assembly, concentrating on the most popular joint

Pressure-Sensitive Adhesives Make Strong Joints at Low Cost
fasteners. PSAs resists flex and vibration, can bond dissimilar materials, and can adhere to low-surface energy plastics. Manufacturers are always looking for faster and better ways to fabricate machines and subcomponents while reducing weight, noise, vibration, and costs. Pressure-sensitive adhesives
