2018年8月4日 · 那么结论就出来啦：QFP，LQFP，TQFP都是方形扁平封装，在厚度上（QFP>LQFP>TQFP），LQFP和TQFP的PCB封装是可以通用的，前提是bodysize或引脚间距相同。 而QFP就不能和这两种通用了。 LQFP和TQFP都属于QFP封装，但是，大部分器件的datasheet上应该都明确指出了他的封装是LQFP还是TQFP，而如果只是说是QFP封装，那么看一下它的L1尺寸就知道他具体是哪种了，因为LQFP和TQFP的L1都是1.0mm，而QFP却有好多 …

Regular QFP are 2.0 to 3.8 mm thick depending on size. TQFP packages range from 32 pins with a 0.8 mm lead pitch, in a package 5 mm by 5 mm by 1 mm thick, to 256 pins, 28 mm square, 1.4 mm thick and a lead pitch of 0.4 mm. [2] TQFPs help solve issues such as increasing board density, die shrink programs, thin end-product profile and portability.

The TQFP comes in different body sizes that range from 5 mm square to 20 mm square. TQFP lead counts, on the other hand, range from 32 to 176. Typical lead pitch values used by TQFP's are: 0.4 mm, 0.5 mm, 0.65 mm, 0.80 mm, and 1.0 mm. A typical TQFP has a body thickness of 1.0 mm. Table 1. Properties of some TQFP's

TQFP (thin quad flat package,即薄塑封四角扁平封装)薄四方扁平封装低成本，低高度引线框封装方案。 薄四方扁平封装对中等性能、低引线数量要求的应用场合而言是最有效利用成本的封 …

Amkor offers a broad line of TQFP (Thin Quad Flat Pack) IC packages. Amkor’s TQFPs are an ideal package for most IC semiconductor technologies such as ASIC, gate arrays (FPGA/PLD), microcontrollers and PMIC controllers.

2024年9月18日 · TQFP packages offer a thin profile and smaller footprint, making them suitable for space-constrained designs. On the other hand, LQFP packages provide higher pin counts and better mechanical stability, making them a good choice for ICs with more I/O requirements.

DIMENSIONS OF PACKAGE DO NOT INCLUDE MOLD FLASH. MOLD FLASH SHALL NOT EXCEED 0.25mm ON ANY SIDE, IF PRESENT. 4. PIN-1 INDENTIFIER IS A MOLDED INDENTATION. 5. EXACT SHAPE OF EACH CORNER IS …
