Abstract
We have developed novel thermosetting low Dk/Df film for 5G application by using novel curable PPE. It showed low Dk, 3.1 at 10GHz, and low Df, 0.001 at 10GHz, high Tg, 200°C, low CTE, 18ppm and low water absorption 0.04%. And it showed good laser via process ability and good adhesion to Electroless plated Cu. We have made stacked substrate with L/S=15μm/15μm comb electrode and B-HAST test was conducted, and it showed good endurance. Transmission loss of the film was better than that of existing epoxy type low Df film.
