F4B High Frequency PCB DK 4.4 PTFE Microwave PCB 6.0mm RF PCB With
Immersion Tin
(Printed Circuit Boards are custom-made products, the picture and
parameters shown are just for reference)
This product(F4BTM-1/2) is made of glass fiber cloth, nano-grade
ceramic powder filling material and PTFE resin through scientific
preparation and strict process suppression. The heat dissipation
effect has been somewhat improved, and the thermal expansion
coefficient is small. Dielectric constant ranges 2.55 to 10.2. This
is also a type of thick PCB material as thick as 12mm. Here’s the
typical properties of F4BTM-1/2 as follows.
