Phukusi la DIP(Dual In-line Package), yomwe imadziwikanso kuti ukadaulo wapawiri-in-line pakuyika, imatanthawuza tchipisi tating'onoting'ono tomwe timapakidwa mumizere iwiri. Chiwerengerocho sichidutsa 100. Chip cha CPU cha DIP chili ndi mizere iwiri ya mapini omwe amafunika kulowetsedwa mu socket ya chip yokhala ndi DIP. Inde, imathanso kulowetsedwa mwachindunji mu bolodi lozungulira ndi nambala yofanana ya mabowo a solder ndi makonzedwe a geometric kwa soldering. Tchipisi zopakidwa ndi DIP ziyenera kulumikizidwa ndi kutulutsidwa kuchokera pa socket ya chip mosamala kwambiri kuti zisawonongeke zikhomo. Mapangidwe a phukusi la DIP ndi: Mipikisano wosanjikiza ceramic DIP DIP, single-wosanjikiza ceramic DIP DIP, lead chimango DIP (kuphatikiza galasi ceramic kusindikiza mtundu, pulasitiki ma CD kapangidwe mtundu, ceramic otsika magalasi ma CD ma CD)

Phukusi la DIP lili ndi izi:

1. Oyenera perforation kuwotcherera pa PCB (kusindikizidwa dera bolodi), yosavuta ntchito;

2. Chiŵerengero chapakati pa chip ndi malo a phukusi ndi chachikulu, kotero kuti voliyumu ndi yaikulu;

DIP ndiye pulogalamu yodziwika bwino ya pulagi, ndipo kugwiritsa ntchito kwake kumaphatikizapo logic yokhazikika IC, kukumbukira ndi mabwalo ang'onoang'ono apakompyuta. 4004, 8008, 8086, 8088 ndi ma CPU ena onse adagwiritsa ntchito mapaketi a DIP, ndipo mizere iwiri ya mapini paiwo imatha kuyikidwa mumipata pa bolodi kapena kugulitsidwa pa bolodi.
