In microelectronics, a quadin-line package (QIP or QIL), is an electronic component package with a rectangular housing and four parallel rows of electrical connecting pins. The package may be through-hole mounted to a printed circuit board (PCB) or inserted in a socket. Rockwell used a QIP with 42 leads formed into staggered rows for their PPS-4 microprocessor family introduced in 1973, and other microprocessors and microcontrollers, some with higher lead counts, through the early 1990s. Some QIP packaged ICs had added heatsinking tabs, such as the HA1306W. * QIP packed ICs * * * * *
