产品和服务

产品介绍
Quad Flat No-lead Package的缩写,即四边扁平无引脚封装;Dual Flat No-lead的缩写,双边扁平无引脚封装,DFN的设计和应用与QFN类似。DFN和QFN的主要差异在于引脚只排列在产品下方的两侧而不是四周

产品特点
适用于表面贴装封装,是具有多个电极触点和一个用于机械和热量完整性暴露的芯片垫的无卤封装。无引脚焊盘设计使其占有更小的PCB面积。考虑到成本、体积各方面的因素,QFN、DFN封装将会是未来几年的一个增长点,发展前景较为乐观。

应用
QFN和DFN被认为是最成熟的行业封装标准之一。QFN和DFN是常用的逻辑、存储器和微控制器。应用于安全芯片、车用电子、医用设备电子、数字化视频、射频、数据采集、电平转换器、变频器、通用MCU、车载音频处理器、锂电池充电管理芯片
