Polytetrafluoroethylene (PTFE) is a synthetic material accidentally invented in the late 1930s while a chemist was endeavoring to develop a new type of perfluorethylene-based refrigerant. Rather than achieving a chlorofluorocarbon, the scientist was surprised to find that the perfluorethylene used in the process reacted with the iron content of its container and polymerized under pressure. Less than a decade later, this new material was being distributed on a commercial scale and was eventually patented under the name Teflon®. In fact, this material was used for a variety of other purposes at first.

PTFE is the use of Teflon in PCB’s dielectric material. Often synthesized with other high speed materials, PTFE’s incorporate the use of ceramic and other resin systems.

Faster communications require high speed resin systems for high bandwidth RF applications in the following industries: Military, Telecommunications (power amplifiers and antennas), RFID, DUT Chip testing, Medical and Automotive (radar).

A hybrid multilayer is a PCB construction that uses dissimilar materials. Reasons for using dissimilar materials include: improving reliability,reducing cost, optimizing electrical performance, and improving manufacturability. For the past several years, hybrid multilayer

PCB construction has flourished in the arena of high-frequency RF applications.
