RF-35
Taconic High Frequency PCB with DK 3.5 Tg 315℃ 10mil 20mil 30mil 60mil RF PCB
(Printed
Circuit Boards are custom-made products, the picture and parameters shown are
just for reference)
RF-35
is the best choice for low cost, high volume commercial microwave and radio
frequency applications.It has an excellent peel strength for 1/2 ounce and 1
ounce copper (even compared to standard epoxy glass), a key aspect of the need
for rework.
RF-35's
Tg exceeds 315 ℃. Its ultra low moisture absorption rate and low dissipation
factor minimize phase shift with frequency. RF-35 used woven fabrics in the
design result in the stable dimension. The laminates are usually orderly clad
on one side or both sides with 1/2,1 and 2 ounces electrodeposited copper respectively.
So
we benefit from its low cost, excellent peel strength, exceptionally low dissipation
factor, low moisture absorption and enhanced surface smoothness.
