Is Teflon the Perfect Material for Your PCB?

Teflon PCB Material

Polytetrafluoroethylene (PTFE) is widely chosen for making PCBs for mobile communication products and satellite system products, among several others. This material is most popularly known by its brand-based name Teflon that is trademarked by DuPont. PCB fabricators are increasingly using this circuit material in the production of high-frequency and high-speed printed-circuit board (PCB) owing to its several unique properties. Let’s see those properties that add to the popularity of Teflon in the production of PCBs for several mission-critical applications. This post also introduces you to a leading Teflon PCB manufacturer in the US.

Why is Teflon Being Used in the Large Scale in High Speed PCBs?

Polytetrafluoroethylene, which is a fluorocarbon-based polymer, has some unique set of mechanical and chemical properties. This material can withstand temperatures of up to 260 degree Celsius and cryogenic temperatures of up to 260 degree Celsius. In addition to this, a few amongst the most uprising characteristics of Teflon material include:

  • High molecular weight
  • Low coefficient of friction
  • Good dielectric properties
  • High electronegativity
  • Low chemical reactivity
  • Good flame resistance
  • High physical strength
  • Temperature stability
  • Moisture proof
  • Resistant to oil, grease
  • Low dielectric constant along with good insulation ability
  • Weather and UV resistance
  • electrical and thermal insulation

Can Every PCB Manufacturer Fabricate Teflon PCB boards?

The aforementioned properties of Teflon make the material one of the top candidates for printed circuit boards. However, not every PCB manufacturer is ready to work with Teflon PCB boards as this laminate demands special equipment and processes. Although you come across a Teflon PCB manufacturer in your search, you must make sure that they have the team who possesses the knowledge, experience and capability to work with the material. The manufacturer you have chosen must be clear about the peculiar properties of Teflon material, so that he/she will form the material appropriately for use in high speed and high frequency boards.

Advanced Applications Using Teflon PCBs

PTFE printed circuit boards are used in several industrial, commercial, and mission-crictical applications. The following are a few important applications utilizing Teflon PCBs:

  • Power amplifiers
  • Handheld cellular devices and WIFI antennas
  • Telematics and infotainment devices
  • Phased array radar systems
  • Aerospace guidance telemetry
  • Automotive cruise control
  • Thermal solutions
  • Wireless base stations
