Taconic RF-35A2 PCB 20mil (0.508 mm) 30mil(0.762mm) 60mil (1.524mm) With Immersion Gold Immersion Silver and Blue Mask
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
Taconic’s RF-35A2 substrate is designed to have ultra-low fiberglass content to achieve "best in class" insertion loss properties and the uniform dielectric constant 3.5 +/-0.05 throughout the laminate. It is a type of ultra low loss power amplifier material.
The uniform dispersion of ceramics throughout the laminate yields an extremely low X and Y thermal expansion coefficient. Low modulus and low X-Y CTE values make RF-35A2 an attractive material for chip carrier in surface mounting technology.
RF-35A2 is manufactured with a proprietary multi-step process with excellent dielectric performance and excellent copper peel adhesion.The low 0.0015 dissipation factor at 10 GHz allows for maximum power transfer resulting in low heat generation.
Benefits:
Low loss properties
DK tolerance of +/- 0.05
Homogeneous DK
Excellent peel strength
Low moisture absorption
