QFP package and plastic square flat plastic Flat Pack Package PFP
QFP (Plastic Quad Flat Package) package small distance between the chip pin, pin very small, or very large scale integrated circuits generally have adopted this package, the pin count is generally 100 or more. Chip package with this form must be used SMD (Surface Mount Device Technology) welded to the chip and the motherboard. SMD mounting parher jic female swivel fitting the chip on the motherboard does not have to punch, usually on the surface of the motherboard designed corresponding pin joints. Will be aligned with the corresponding chip solder joints of the foot, can be realized with the motherboard welding. In this way welding up the chip, it is difficult if not special tools dismantled.
PFP (Plastic Flat Package) encapsulated chip and QFP basically the same way. The only difference is the QFP is generally square, and the PFP can be either square, it can be rectangular.
QFP / PFP package has the following characteristics:
1 Suitable for SMD surface female swivel fitting mount technology circuit board mounted on the PCB layout.
(2) suitable for high frequency use.
3 easy operation and high reliability.
4 chip area and the ratio between the smaller package size.
Intel Series 486 CPU, 80286, 80386, and certain motherboards using this package.
