产品介绍Product Introduction：
HJY300A-PP是一款半固化片，以HJY-A基材材料为基础，在多层板叠构中与HJY-A板材相兼容。该固化片可以在多层板中多次压合，与FR4的较低压合温度兼容且具有较好的流胶性能，可以很好地满足高频多层板的压合需求。
The HJY300A-PP is a prepreg based on HJY-A substrate material and is compatible with HJY-A sheets in multilayer stacks. The cured sheet can be laminated multiple times in the multilayer board, is compatible with the lower laminating temperature of FR4 and has better adhesive flow performance, and can well meet the laminating requirements of the high-frequency multilayer board.
应用Applications：
l高频多层板粘结片 High frequency multi-layer board bonding sheet
