RF PCB Built on 6.15 DK RF-60TC 10mil, 20mil, 30mil and 60mil Coating with Immersion Gold, Tin, HASL and OSP for Miniaturized Antenna
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
RF-60TC is a ceramic-filled PolyTetraFluoride(PTFE) based (fiberglass substrate for the PCB of high power RF and microwave applications. It is designed to provide lower operating temperature in high power applications and the 6.15DK market. By improving dielectric heat dissipation and exceptionally lower dielectric losses, a better gain and efficiency are got in miniaturized antenna applications
RF-60TC's enhanced heat transfer function allows additional design margin to extend the life of active components and improve long-term reliability.
RF-60TC with extremely low profile and reverse treated copper is excellent to reduce insertion loss. Heavy metal based laminate is also available. RF-60TC’s low CTE and improved dimensional stability make it possible to build multi-layer PCB with improved PTH reliability.
