1. Igikoresho cyoroshye cya COB
Urubuga rwitondewe rushobora kubona ko hari ikintu cyirabura ku mbaho zimwe zumuzunguruko, none iki nikihe?Kuki iri ku kibaho cyumuzunguruko?Ingaruka ni izihe?Mubyukuri, ubu ni ubwoko bwa paki.Dukunze kubyita "pack pack".Bavuga ko paki yoroshye mubyukuri "ikomeye", kandi ibiyigize ni epoxy resin., Mubisanzwe tubona ko ubuso bwakirwa bwumutwe wakira nabwo buri muri ibi bikoresho, kandi chip IC iri imbere.Iyi nzira yitwa "guhuza", kandi mubisanzwe tuyita "guhuza".
Nuburyo bwo guhuza insinga mugikorwa cyo gukora chip.Izina ryicyongereza ni COB (Chip On Board), ni ukuvuga chip kumupaki.Ubu ni bumwe mu buhanga bwo kwishyiriraho chip.Chip ifatanye na epoxy resin.Yashizwe kumurongo wacapwe wa PCB, noneho kuki imbaho zimwe zumuzunguruko zidafite ubu bwoko bwa paki, kandi ni ibihe bintu biranga ubu bwoko?
2. Ibiranga COB yamashanyarazi
Ubu bwoko bwa tekinoroji yo gupakira byoroshye ni kubiciro.Nka chip yoroheje yambaye ubusa, kugirango irinde IC imbere kwangirika, ubu bwoko bwo gupakira busaba kubumba inshuro imwe, ubusanzwe bushyirwa hejuru yumuringa wumuringa wibibaho byumuzunguruko.Ni uruziga kandi ibara ni umukara.Ubu buryo bwo gupakira bufite ibyiza byigiciro gito, kuzigama umwanya, urumuri kandi ruto, ingaruka nziza zo gukwirakwiza ubushyuhe, nuburyo bworoshye bwo gupakira.Imirongo myinshi ihuriweho, cyane cyane izunguruka zihenze cyane, gusa igomba guhuzwa murubu buryo.Chip yumuzunguruko ijyanwa hamwe ninsinga nyinshi zicyuma, hanyuma igashyikirizwa uwabikoze kugirango ashyire chip ku kibaho cyumuzunguruko, ayigurisha akoresheje imashini, hanyuma ashyireho kole kugirango akomere kandi akomere.
3. Ibihe byo gusaba
Kuberako ubu bwoko bwa paki bufite umwihariko wabwo, bukoreshwa no mumuzunguruko wa elegitoroniki zimwe na zimwe, nk'abakinyi ba MP3, ingingo za elegitoronike, kamera ya digitale, imashini yimikino, nibindi, mugukurikirana imiyoboro ihendutse.
Mubyukuri, ibikoresho bya COB byoroshye gupakira ntabwo bigarukira gusa kuri chip, binakoreshwa cyane muri LED, nkumucyo wa COB, ni tekinoroji ihuriweho n’ikoranabuhanga rifatanije neza n’icyuma cyerekana indorerwamo kuri chip ya LED.
