PCB封装之QFP、PQFP、LQFP、TQFP及PCB详解 - CSDN博客
2018年8月4日 · 借用一段话:“QFP(Quad Flat Package)为四侧引脚扁平封装,是表面贴装型封装之一,引脚从四个侧面引出呈海鸥翼 (L)型。 基材有陶瓷、金属和塑料三种。 从数量上看,塑料封装占绝大部分。 当没有特别表示出材料时,多数情况为塑料QFP。 塑料QFP是最普及的多引脚LSI(大规模集成电路)的封装。 不仅用于微处理器,门陈列等数字逻辑LSI电路,而且也用于VTR 信号处理、音响信号处理等模拟LSI 电路。 引脚中心距有1.0mm、0.8mm、0.65mm、0.5mm …
Amkor’s ExposedPad LQFP/TQFP family of power IC packages significantly increases the thermal eficiency of power-constrained standard LQFP and TQFP packages. These packages can increase heat dissipation by as much as 110% over standard LQFP/TQFP packages, thereby expanding the margin of operating parameters.
