ngwugwu DIP(Ngwugwu Ngwunye In-line Dual), makwaara dị ka teknụzụ nkwakọ ngwaahịa in-line, na-ezo aka na ibe sekit agbakwunyere nke etinyere n'ụdị ọnụọgụ abụọ. Ọnụ ọgụgụ ahụ n'ozuzu anaghị agafe 100. Ihe mgbawa CPU ngwugwu DIP nwere ahịrị abụọ nke ntụtụ dị mkpa ka ịtinye n'ime oghere mgbawa nwere usoro DIP. N'ezie, a pụkwara itinye ya ozugbo n'ime bọọdụ sekit nwere ọnụ ọgụgụ nke oghere ndị na-ere ahịa na nhazi geometric maka ire ere. Ekwesịrị ịkwanye ibe ngwungwu DIP ma wepụ ya na oghere mgbawa ahụ site na nlekọta pụrụ iche iji zere imebi ntụtụ. DIP ngwugwu Ọdịdị ụdị bụ: multi-layer seramiiki DIP DIP, otu oyi akwa DIP DIP, ndu etiti DIP (gụnyere iko seramiiki akara ụdị, plastic nkwakọ Ọdịdị ụdị, seramiiki ala agbaze iko ụdị)

ngwugwu DIP nwere njirimara ndị a:

1. Sutable maka perforation ịgbado ọkụ na PCB (e biri ebi sekit osisi), mfe na-arụ ọrụ;

2. Ọnụ ọgụgụ dị n'etiti mpaghara mgbawa na mpaghara ngwugwu buru ibu, ya mere olu ahụ dịkwa ukwuu;

DIP bụ ngwungwu nkwụnye kachasị ewu ewu, ngwa ya gụnyere ọkọlọtọ IC, ebe nchekwa na sekit microcomputer. Nke mbụ 4004, 8008, 8086, 8088 na CPU ndị ọzọ niile ji ngwugwu DIP, na ahịrị abụọ nke pin na ha nwere ike itinye n'ime oghere na motherboard ma ọ bụ resịrị na motherboard.
