电动车“马力渴望”之下,国产车规级“烧结银”扩充朋友圈
21世纪经济报道记者 赵云帆 上海报道 一项关键新能源车产业的突破,悄然隐身于一场新能源车发布会的身后。 近日,上汽集团旗下智己汽车新版L6车型正式对外发布。21世纪经济报道记者注意到,智己L6首次使 用了国内导电银浆企业帝科股份(300842.SZ)的调光膜银浆产品作为其主打功能"瞬感智控"防晒天幕 的关键材料。 另据记者了解,今年3月,帝科电子材料官网公众号推文显示,公司的"湃泰PacTite品牌"正式通过IATF 16949认证,而该"厂牌"产品包括芯片封装银胶、烧结银、AMB钎焊浆料、印刷电子银浆等。调光膜银 浆产品即属于上述车规级印刷电子银浆。 这也意味着,帝科股份或逐步开启车规级产品应用的放量周期——特别是以烧结银、AMB钎焊浆料、 印刷电子银浆为主的汽车银材电子业务。 而以碳化硅为代表的新能源车关键功率半导体模组需求的持续增长,意味着作为模组重要辅材的烧结银 需要补足其国产化短板。 资料显示,碳化硅芯片工作温度高达200℃以上,且开关频率提升10倍,对封装材料的各项性能要求极 高。而烧结银浆材料在先进的烧结技术支持下,能于基板形成致密结构的导热导电层,提供优异的电导 率和热导率,同时减少界面热阻 ...
