Note: In the packaging of  CMD integrated circuits (crab base)  of  QFP type, the pins  are placed on the four sides of the IC. The pins on each side of this type of package are from 8 to  70 pins on each side with the distance of both pins on each side  from 0.4mm to 1mm. The appearance of QFN packages  is similar to QFP. 

QFP chips are one of the most common IC packages, those small chips have two rows of parallel pins and a rectangular, black cube and a plastic housing.



Both IC pins are 2.54mm apart from each other, which is a suitable and standard distance for printed circuit board fiber connections. Generally, the dimensions and QFP packages depend on the number of pins that may be in each four. There are up to 64 numbers on each side. The distance between them allows QFP ICs to be placed in the center of the printed circuit board as a standard.



Many modern and advanced microprocessors, sensors and other ICs are produced in QFN and QFP packages. 

Structure and internal structure of QFP chips: Compressed PVC core material; Structure of bases (copper) aluminum alloy; How to install and assemble in DIP and deep


 Packages are packages that  place IC DIE and splays inside a device  . And it has made communication with them  easier. The external DIE leads are connected to a pad or pin on the package via a   small piece of gold wire  . There are different types of packages,  each of which is unique in terms of  dimensions, number of pins, installation and establishment  .
