TSM-DS3 2-Layer 0.8mm PCB – Low-Loss Ceramic-Filled 30mil Core with Immersion Gold Finish
1.Introduction to TP600 2-Layer 5.1mm Thick PCB
TSM-DS3 is a ceramic-filled reinforced material with very low fiberglass content (~5%) that rivals epoxies in fabricating large-format complex multilayers. It is a thermally stable, industry-leading low-loss core (Df = 0.0011 at 10 GHz) that can be manufactured with the predictability and consistency of the best fiberglass-reinforced epoxies. TSM-DS3 was developed for high-power applications (TC = 0.65 W/m·K) where it is necessary for the dielectric material to conduct heat away from other heat sources in a PWB design. It also features very low coefficients of thermal expansion for demanding thermal cycling environments.
