Iterambere ryiterambere ryumuzingo wacapwe (PCB)

Kuva mu ntangiriro z'ikinyejana cya 20, iyo terefone yahinduye ituma imbaho ​​z'umuzunguruko ziba nyinshi ,.icyapa cyumuzingo cyacapwe (PCB)inganda zashakishaga ubucucike buri hejuru kugirango zuzuze icyifuzo cya elegitoroniki ntoya, yihuse kandi ihendutse.Icyerekezo cyo kongera ubucucike nticyigeze kigabanuka na gato, ariko cyihuse.Hamwe nogutezimbere no kwihutisha imikorere yumuzunguruko uhuriweho buri mwaka, inganda ziciriritse ziyobora icyerekezo cyiterambere cyikoranabuhanga rya PCB, ziteza imbere isoko ryumuzunguruko, kandi byihutisha iterambere ryikibaho cyacapwe (PCB).

Kuva ubwiyongere bwumuzunguruko uhuriweho biganisha ku kwiyongera kwinjiza / gusohoka (I / O) ibyambu (amategeko yubukode), paki nayo igomba kongera umubare wihuza kugirango yakire chip nshya.Mugihe kimwe, ingano ya paki ihora igeragezwa kuba nto.Intsinzi ya tekinoroji yububiko bwa tekinoroji yatumye bishoboka gukora ibicuruzwa birenga 2000 bigezweho, kandi uyu mubare uziyongera kugera ku 100000 mugihe gito mugihe mudasobwa zidasanzwe za super-Super zigenda ziyongera.Urugero rwa Blue Gene ya IBM, ifasha gutondekanya amakuru menshi ya ADN.

PCB igomba kugendana nubucucike bwumurongo wapaki hanyuma igahuza nubuhanga bugezweho bwa tekinoroji.Guhuza chip itaziguye, cyangwa tekinoroji ya flip, ifata chip ku kibaho cyumuzunguruko: kurenga ibipfunyika bisanzwe.Ibibazo bikomeye byifashisha ikoranabuhanga rya chip bitera ibigo byubuyobozi bwumuzunguruko byakemuwe gusa mugice gito kandi bigarukira kumubare muto wibikorwa byinganda.

Isosiyete itanga PCB yarangije kugera kumipaka myinshi yo gukoresha inzira zumuzunguruko kandi igomba gukomeza guhinduka nkuko byateganijwe, hamwe no kugabanya uburyo bwo gutobora no gucukura imashini.Inganda zikora ibintu byoroshye, akenshi zititaweho kandi zititaweho, zayoboye inzira nshya byibuze imyaka icumi.Tekinike yo guhimba ya Semi-yongeyeho irashobora gutanga imirongo yacapishijwe umuringa munsi yubugari bwa ImilGSfzm, kandi gucukura laser birashobora kubyara microholes ya 2mil (50Mm) cyangwa munsi yayo.Kimwe cya kabiri cyimibare irashobora kugerwaho mumirongo mito yiterambere, kandi turashobora kubona ko aya majyambere azagurishwa vuba.

Bumwe muri ubwo buryo bukoreshwa no mu nganda zikomeye z’umuzunguruko, ariko bumwe muri bwo buragoye kubishyira mu bikorwa muri uru rwego kuko ibintu nko kubika vacuum bidakunze gukoreshwa mu nganda zikomeye z’umuzunguruko.Umugabane wo gucukura laser urashobora kwitezwaho kwiyongera nkuko gupakira hamwe na elegitoronike bisaba imbaho ​​nyinshi za HDI;Inganda zikomeye zumuzunguruko nazo zizongera ikoreshwa ryikariso ya vacuum kugirango habeho ubucucike bucye bwa kabiri bwiyongera.

Hanyuma ,.Ubuyobozi bwa PCBinzira izakomeza guhinduka kandi umugabane wisoko ryibikorwa byinshi biziyongera.Uruganda rwa PCB ruzabona kandi epoxy polymer sisitemu yumuzunguruko yatakaje isoko ryabo kugirango polymers ishobora gukoreshwa neza kuri laminates.Inzira irashobora kwihuta mugihe epoxy irimo flame retardants yabujijwe.Twibutse kandi ko imbaho ​​zoroheje zakemuye ibibazo byinshi by’ubucucike bukabije, zishobora guhuzwa n’ubushyuhe bwo hejuru butarimo ubushyuhe bw’imisemburo, kandi ibikoresho byoroha bitarimo ubutayu n’ibindi bintu biri ku “rutonde rw’abicanyi.”

Huihe Circuits nisosiyete ikora PCB, ikoresha uburyo bwo gukora ibinure kugirango harebwe ko ibicuruzwa bya PCB bya buri mukiriya bishobora koherezwa mugihe cyangwa mbere yigihe giteganijwe.Hitamo, kandi ntugomba guhangayikishwa nitariki yo gutanga.
