Igishushanyo gishobora gushushanya ikibaho kidasanzwe cyanditseho imizunguruko (PCB). Niba insinga idasaba urwego rwinyongera, kuki uyikoresha? Kugabanya ibice ntibyatuma ikibaho cyumuzunguruko cyoroha? Niba hari ikibaho gito cyumuzunguruko, ikiguzi nticyaba gito? Ariko, mubihe bimwe, kongeramo urwego bizagabanya ikiguzi.

Imiterere yinama yumuzunguruko
Ikibaho cyumuzingi gifite ibyiciro bibiri bitandukanye: imiterere yibanze nuburyo bubi.

Mu miterere yibanze, ibice byose byayobora mukibaho cyumuzunguruko bisizwe kubintu byingenzi; muburyo bwambarwa bwa fayili, gusa urwego rwimbere rwimbere rwikibaho cyumuzunguruko rushyizwe hejuru yibikoresho byingenzi, naho urwego rwimbere rwimbere ni ikibaho cya dielectric. Inzira zose ziyobora zahujwe hamwe binyuze muri dielectric ukoresheje inzira yo kumurika.

Ibikoresho bya kirimbuzi ni ikibaho cyimpande zombi zambaye uruganda. Kuberako buri kintu gifite impande ebyiri, iyo zikoreshejwe neza, umubare wimikorere ya PCB numubare uringaniye. Ubona gute ukoresheje foil kuruhande rumwe nuburyo bwibanze kubisigaye? Impamvu nyamukuru nizo: ikiguzi cya PCB nurwego rwo kugonda PCB.

Inyungu yikiguzi cyumubare wumubare wumuzunguruko
Kubera kubura urwego rwa dielectric na foil, igiciro cyibikoresho fatizo kuri PCB zidasanzwe zifite umubare muto ugereranije na PCBs zifite numero. Nyamara, igiciro cyo gutunganya PCBs zidasanzwe-kiri hejuru cyane ugereranije na PCBs. Igiciro cyo gutunganya urwego rwimbere ni kimwe; ariko foil / core structure biragaragara ko byongera igiciro cyo gutunganya urwego rwo hanze.

Odd-ifite numero-ya PCBs igomba kongeramo uburyo budasanzwe bwa laminated core layer ihuza inzira ishingiye kumiterere yibanze. Ugereranije n’imiterere ya kirimbuzi, umusaruro w’inganda zongerera umwete imiterere ya kirimbuzi uzagabanuka. Mbere yo kumurika no guhuza, intangiriro yinyuma isaba gutunganyirizwa hamwe, byongera ibyago byo gushushanya hamwe namakosa yo guterana kumurongo wo hanze.

Kuringaniza imiterere kugirango wirinde kunama
Impamvu nziza yo kudashushanya PCB ifite umubare udasanzwe wibice ni uko umubare udasanzwe wibibaho byumuzunguruko byoroshye kugorama. Iyo PCB imaze gukonjeshwa nyuma yuburyo bwo guhuza imirongo myinshi, impagarara zitandukanye za lamination yimiterere yibanze hamwe nuburyo bwambarwa bwa fayili bizatera PCB kunama iyo ikonje. Nkuko umubyimba wibibaho byumuzunguruko wiyongera, ibyago byo kunama PCB igizwe nibintu bibiri bitandukanye byiyongera. Urufunguzo rwo gukuraho ikibaho cyizunguruka ni ukwemera kuringaniza.

Nubwo PCB ifite urwego runaka rwo kunama yujuje ibyangombwa bisabwa, imikorere ikurikira izagabanuka, bigatuma ibiciro byiyongera. Kuberako ibikoresho byihariye nubukorikori bisabwa mugihe cyo guterana, ubunyangamugayo bwo gushyira ibice buragabanuka, byangiza ubuziranenge.

Koresha PCB ifite numero
Iyo PCB ifite numero idasanzwe igaragara mugushushanya, uburyo bukurikira burashobora gukoreshwa kugirango ugere kumurongo wuzuye, kugabanya ibiciro byo gukora PCB, no kwirinda kunama PCB. Uburyo bukurikira butunganijwe muburyo bukunzwe.

Ikimenyetso kandi ukoreshe. Ubu buryo burashobora gukoreshwa niba ingufu zishusho ya PCB iringaniye kandi ibimenyetso byerekana bidasanzwe. Igice cyongeweho ntabwo cyongera ikiguzi, ariko kirashobora kugabanya igihe cyo gutanga no kuzamura ireme rya PCB.

Ongeraho andi mashanyarazi. Ubu buryo burashobora gukoreshwa mugihe ingufu zishusho ya PCB idasanzwe kandi ibimenyetso byerekana ni ndetse. Uburyo bworoshye nukwongeramo urwego hagati ya stack udahinduye izindi miterere. Ubwa mbere, shyira insinga muburyo budasanzwe-PCB, hanyuma ukoporore hasi hagati, hanyuma ushireho ibice bisigaye. Ibi ni kimwe nibiranga amashanyarazi biranga umubyimba wuzuye.

Ongeraho ibimenyetso byerekana ibimenyetso hafi yikigo cya PCB. Ubu buryo bugabanya ubusumbane bwa stacking kandi butezimbere ubuziranenge bwa PCB. Banza, ukurikire ibice bitandukanijwe numurongo ugana inzira, hanyuma wongereho ibimenyetso byerekana ibimenyetso, hanyuma ushireho ibimenyetso bisigaye. Ikoreshwa mumuzunguruko wa microwave hamwe nibitangazamakuru bivanze (imiyoboro itandukanye ya dielectric).

Ibyiza bya PCB iringaniye
Igiciro gito, ntabwo byoroshye kugoreka, kugabanya igihe cyo gutanga no kwemeza ubuziranenge.
