PTFE Teflon PCB to meet the demand for faster communications. Please refer Teflon PCB Applications. Teflon materials are valued for their suitability in high-frequency electronic applications. At Microwave RF PCB, FR-4 Material (approx. 4.5) dielectric constant o is often too high, its significant signal loss during transmission across the printed circuit board. Luckly, Teflon materials boast dielectric constant values as low as 3.5 or less, it is ideal material for overcoming the high-speed limitations of FR-4. The most common of these Teflon PCB materials were developed by Rogers. In addition to a reduction in dielectric constant, these materials also offer very impressive thermal characteristics for High Temperature PCB applications, reaching Tg values as high as 280°C. A datasheet comparison is shown below for two different PTFE teflon pcb materials, RO4003C and RO4350B.

Drilling: This is a new procedure ideal for drilling PTFE substrates covered with copper. Drilling must be utilized with a high chip load. This removes fibers and PTFE tailing. In most cases, PCB fabricators prefer ceramic-filled laminates since they can drill them easily.asia bookies
Lamination: Teflon substrates don’t require oxide pretreatment. PCB fabricators laminate PTFE and copper films at high pressures without bonding films or pre-pegs. Sometimes, PTFE PCB manufacturers use bonding films or prepreg of a very low melting point to minimize the processing temperatures. PTFE-FR4 laminates are ideal in some applications, but they need oxide pretreatment.
