Taconic RF-35 High Frequency PCB |
|
|
|
|
|
RF-35 is an organic-ceramic laminate material in the ORCER?(Organic Ceramic) family of Taconic products. It is based on woven glass reinforcement. RF-35 is the result of Taconic's expertise in both ceramic filling technology and coated polytetrafluoride （PTFE) fiberglass |
|
|
|
|
|
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.
