High frequency PCB is the circuit frequency above 1GHz,there are very strict requirements for its performance,tolerance and technology specification.
The material is very important for the High frequency PCB,below are the basis characters for the high frequency PCB material selection.
1. The dielectric constant have to be small and stable,high dielectric constant will cause the signal transmission delay.
2. The dielectric loss have to be small,it will influence the quality of signal transmission,the dielectric loss is smaller,the signal loss is smaller.
3. The coefficient of thermal expansion should be the same with the cooper foil,or it will cause the copper foil separation during the change of cold and heat.
4. Low water absorption capacity,or it will influence the dielectric constant and dielectric loss in wet condition
5. The heat resistance,chemical resistance,impact strength, peel strength should be all good.
