VT-901PP 106HW-75/106HW-80 VT-47PP 1080VF-68/106VF-76UL Approval: E214381 Version: B4 29/12/2017
General InformationVT-901PP HW type is a high performance ceramic-filled polyimide prepreg, designed for use in filling etched areas in polyimide multilayers that contain thick copper layers and for filling clearance holes in metal cores. The filler in the resin serves to reduce shrinkage and inhibit crack formation during through-hole drilling in filled clearance areas. VT-47PP VF type is a high Tg, lead free compatible and ceramic-filled prepreg, designed for application in filling clearance holes or via holes. The ceramic is filled to minimize resin shrinking and cracking in filled clearance holes.
