Yintoni ukupakisha

Emva kwenkqubo ende, ukusuka kuyilo ukuya kwimveliso, ekugqibeleni ufumana i-IC chip.Nangona kunjalo, i-chip incinci kwaye ibhityile kangangokuba inokukrwela ngokulula kwaye yonakaliswe ukuba ayikhuselwanga.Ngaphezu koko, ngenxa yobukhulu obuncinci be-chip, akulula ukuyibeka ebhodini ngesandla ngaphandle kwendlu enkulu.

Ngoko ke, inkcazo yephakheji ilandelayo.

Kukho iindidi ezimbini zeepakethi, iphakheji ye-DIP, efumaneka ngokuqhelekileyo kwizinto zokudlala zombane kwaye ibonakala ngathi i-centipede emnyama, kunye nephakheji ye-BGA, efumaneka ngokuqhelekileyo xa uthenga i-CPU kwibhokisi.Ezinye iindlela zokupakisha ziquka i-PGA (i-Pin Grid Array; i-Pin Grid Array) esetyenziswe kwii-CPU zakuqala okanye inguqu elungisiweyo ye-DIP, i-QFP (i-plastic square flat package).

Ngenxa yokuba zininzi iindlela zokupakisha ezahlukeneyo, oku kulandelayo kuya kuchaza iipakethe ze-DIP kunye ne-BGA.

Iiphakheji zemveli eziye zanyamezela iminyaka

Iphakheji yokuqala eyakwaziswa yi-Dual Inline Package (DIP).Njengoko unokubona kumfanekiso ongezantsi, i-IC chip kule phakheji ibonakala ngathi i-centipede emnyama phantsi komqolo ophindwe kabini wezikhonkwane, ezithandekayo.Nangona kunjalo, ngenxa yokuba ubukhulu becala yenziwe ngeplastiki, isiphumo sokutshatyalaliswa kobushushu sibi kwaye asikwazi ukuhlangabezana neemfuno zeechips ezikhawulezayo zangoku.Ngesi sizathu, uninzi lwee-ICs ezisetyenziswa kule phakheji ziitshiphusi ezihlala ixesha elide, njenge-OP741 kumzobo ongezantsi, okanye ii-ICs ezingadingi santya esingako kwaye zineetshiphusi ezincinci ezine-vias ezimbalwa.

I-IC chip ngasekhohlo yi-OP741, i-amplifier yombane eqhelekileyo.

I-IC ngakwesobunxele yi-OP741, i-amplifier yombane eqhelekileyo.

Ngokuphathelele iphakheji ye-Ball Grid Array (BGA), incinci kunepakethe ye-DIP kwaye inokungena lula kwizixhobo ezincinci.Ukongezelela, ngenxa yokuba izikhonkwane zibekwe phantsi kwe-chip, izikhonkwane ezininzi zetsimbi ziyakwazi ukuhlaliswa xa kuthelekiswa ne-DIP.Oku kuyenza ilungele iitshiphusi ezifuna inani elikhulu labafowunelwa.Nangona kunjalo, kubiza kakhulu kwaye indlela yokudibanisa inzima kakhulu, ngoko isetyenziswa kakhulu kwiimveliso zexabiso eliphezulu.
