Hariho uruhande rumwe, impande ebyiri kandi imbaho nyinshi zumuzunguruko .Umubare wibibaho byinshi ntabwo bigarukira.Hano hari PCB zirenga 100.Ibisanzwe byinshi PCBs ni bine kandi imbaho esheshatu .Noneho ni ukubera iki abantu bafite ikibazo "Kuki PCB igizwe ninama nyinshi igizwe nimirongo yose ifite numero? Ugereranije, PCBs zifite numero zifite PCBs zirenze nimero zidasanzwe, kandi bafite ibyiza byinshi.
1. Igiciro gito
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 rwinyuma. PCB idasanzwe ifite numero PCB ikeneye kongeramo uburyo budasanzwe bwa laminated core layer ihuza inzira ishingiye kubikorwa byingenzi.Ugereranije n’imiterere ya kirimbuzi, umusaruro w’inganda zongerera ifumbire 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.
2. Kuringaniza imiterere kugirango wirinde kunama Impamvu nziza yo kudashushanya PCB ifite nimero idasanzwe ni uko umubare udasanzwe wibibaho byumuzunguruko byoroshye kugorama.Iyo PCB imaze gukonja nyuma yuburyo bwo guhuza imirongo myinshi, impagarara zitandukanye zo kumurika kumiterere 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.
Kubishyira mu bundi buryo, biroroshye kubyumva: Mubikorwa bya PCB, imbaho enye zigenzurwa neza kuruta ikibaho cyibice bitatu, cyane cyane mubijyanye no guhuza.Urupapuro rwintambara rwibice bine rushobora kugenzurwa munsi ya 0.7% (IPC600) ibicuruzwa byose.Kubwibyo, uwashushanyije muri rusange ntabwo ashushanya ikibaho kidasanzwe gifite nimbaho, kabone niyo igipande kidasanzwe cyabonye imikorere, kizaba cyarakozwe nkigice cyimpimbano ndetse gifite numero, ni ukuvuga ibice 5 byashizweho nkibice 6, n'ibice 7 byateguwe nkibibaho 8. Ukurikije impamvu zavuzwe haruguru, imbaho nyinshi za PCB zateguwe hamwe nimero-zuzuye kandi nkeya zidasanzwe.
Nigute ushobora kuringaniza stacking no kugabanya ikiguzi cya PCB idasanzwe?
Byagenda bite niba PCB ifite numero idasanzwe igaragara mugushushanya?
Uburyo bukurikira burashobora kugera kumurongo wuzuye, kugabanya Gukora PCB ibiciro, kandi wirinde kunama PCB.
1) Ikimenyetso cyerekana 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. 2) Ongeraho urwego rwinyongera.Ubu buryo burashobora gukoreshwa niba ingufu zishusho ya PCB idasanzwe kandi ibimenyetso byerekana ni ndetse.Uburyo bworoshye nukwongeramo urwego hagati ya stack udahinduye izindi miterere.Banza, ukurikize imiterere ya PCB idasanzwe, hanyuma ukoporore hasi hagati kugirango ushireho ibice bisigaye.Ibi ni kimwe nibiranga amashanyarazi biranga umubyimba wuzuye. 3) Ongeraho ikimenyetso cyerekana 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 mumashanyarazi ya microwave hamwe nibitangazamakuru bivanze (imiyoboro itandukanye ya dielectric).
