Pyraluxâ flexible circuit materials.

The tight bending radii present in many design configurations require flexible metal layers with high electrical conductivity. A wide variety of materials and configurations are available to address the needs of today s design applications. Pyralux tk copper clad laminate and bonding film system. Selecting the optimum flex circuit board material is a key element to the success of a flexible circuit design.

Flex circuit substrate materials fall into 2 general categories adhesiveless and adhesive based. These materials have gained popularity for several reasons. Flexible circuits pose unique challenges for metallization. Adhesiveless adhesiveless materials manufactured as either cast dielectric on copper or sputtered copper on dielectric film.

It is ideal for use in rigid flex and multilayer flex applications which require advanced performance such as low dissipation loss for high speed high frequency thermal resistance and high reliability. Product manager adhesiveless products 4 03 evaluation testing thermal cycling peel strength performance thermal cycling has been established as one of the standard accelerated aging test methods to assess functional reliability throughout the industry. Material selection is determined by the combination of the electrical mechanical bend requirements and cost considerations of a specific design. 17 35 and 70um.
