About F4B High Frequency PCB
Wangling F4B is based on the electrical performance requirements of microwave circuits,
It is a kind of excellent microwave printed circuit board with good electrical properties and high mechanical strength.
Design Of F4B High Frequency PCB
In the design of high-frequency PCB, designers usually pay more attention to the dielectric constant (DK) and tangent loss (DF) of PCB when selecting materials, and only pay attention to the thickness of copper foil when selecting copper foil, which is easy to ignore the influence of different types of copper foil roughness on the electrical properties of products.
SEM analysis of the micro morphology of different types of copper foil and dielectric contact surface shows that the roughness of different types of copper foil is quite different. In the design of microstrip line, the roughness of copper foil and dielectric contact surface will directly affect the insertion loss of the whole transmission line.
Material Parameters Of F4B PCB
Wangling F4B is made of high quality materials according to the electrical performance requirements of microwave circuits. It has good electrical performance and high mechanical strength. It is an excellent microwave printed circuit subgrade board. Normal 15N/cm constant damp heat and 260℃±2℃ fusion welding material to keep 20 seconds without foaming, no stratification and peeling strength ≥12 N/cm.
