SpletIntroductionManaging heat in electronic systems is crucial for ensuring product reliability. Integrated circuits (ICs) exposed to high temperatures can fail or malfunction in the field, thus requiring costly repair or redesign. Typical thermal-resistance parameters give the resistance from the IC junction to some external reference point. Two popul http://fullformbook.com/Studies/tqfp

SpletWe also offer the TQFP in an Exposed Pad configuration (TQFP-ep). This is a thermally enhanced version of the TQFP package. Thermal enhancement is achieved by means of an exposed die pad, which can be soldered to a mother PC board for effective heat removal and grounding, if needed. This enhanced thermal package is made possible SpletExposedPad LQFP/TQFP Configuration Options ExposedPad LQFP/TQFP Nominal Package Dimensions (mm) Lead Count Body Size Body Thickness Lead Form Standoff Foot Length Tip-to-Tip Tray Matrix Units Per Tray 32 5 x 5 1.00 1.00 0.10 0.60 7.0 12 x 30 360 32/48/64 7 x 7 1.00 1.00 0.10 0.60 9.0 10 x 25 250 44/52/64/80 10 x 10 1.0/1.4 1.00 0.10 0.60 12.0 8 ...

SpletTQFP是英文thin quad flat package的缩写，即薄塑封四角扁平封装。 四边扁平封装（TQFP）工艺能有效利用空间，从而降低对印刷电路板空间大小的要求。 由于缩小了高度和体积，这种封装工艺非常适合对空间要求较高的应用，如PCMCIA 卡和网络器件。 几乎所有ALTERA的CPLD/FPGA都有 TQFP 封装。 5、 PQFP封装 PQFP是英文Plastic Quad Flat … http://www.sz-jlc.tv/support/123-qfp-pqfp-lqfp-tqfp-pcb.html
SpletA QFP is a surface-mounted IC (integrated circuit) package having “gull-wing” like leads extending on either side of their four edges. Generally, these packages are extensively utilized by very large-scale and large-scale ICs. The number of pins utilized in this technology is more than one hundred, making it pretty efficient.

(The previous engineer designed a chip with 626 --yes, 626-- pins, which I've gotta deal with). Now I only really need to connect roughly 250 or so of these to test.

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. fox baitcastSpletTQFP is pretty different mechanically to PLCC, it's not just the same thing with leads bent over, the leads are a different shape wider at the top where it can contact a socket then narrower and folded in a J shape for surface mount attachment, generally quite a bit larger, also the pin 1 location isn't on a corner, it's halfway along the side. 3 black tea versus coffee
