Igiciro cyo gukora cyumuzunguruko nicyo cyahangayikishijwe cyane naba injeniyeri bose ba elegitoronike, barashaka kumenya inyungu nini yibicuruzwa byabo hamwe nigiciro gito.Nyamara, niki kigira ingaruka mubyukuri kubicuruzwa byubuyobozi bwumuzunguruko? Hano, uzabikora menya ibintu byose bishoboka bizongera igiciro cya PCB.
Impamvu yibanze ikora ikiguzi cya PCB
1) Ingano ya PCB nubunini
Biroroshye kumva uburyo ingano nubunini bizagira ingaruka kubiciro bya PCB, ingano nubunini bizakoresha ibikoresho byinshi.
2) ubwoko bwibikoresho bya substrate byakoreshejwe
Ibikoresho bimwe bidasanzwe bikoreshwa mubikorwa byihariye byakazi byaba bihenze cyane kuruta ibikoresho bisanzwe. Gukora imbaho zicapye zicapye biterwa nibintu byinshi bishingiye kubisabwa, bigengwa ahanini ninshuro n'umuvuduko wibikorwa, hamwe nubushyuhe bukabije bwo gukora.
3) Umubare w'ibyiciro
ibyiciro byinshi bisobanurwa mubiciro byinyongera kubera intambwe nyinshi zo gukora, ibikoresho byinshi, nigihe cyo kongera umusaruro.
4) PCB igoye
PCB igoye biterwa numubare wibice hamwe numubare wa vias kuri buri cyiciro, kuko ibi bisobanura itandukaniro ryibice aho vias itangirira kandi igahagarara, bisaba intambwe nyinshi zo kumurika no gucukura mubikorwa bya PCB.Ababikora basobanura uburyo bwo kumurika nko gukanda ibice bibiri byumuringa na dielectrics hagati yumuringa wegeranye ukoresheje ubushyuhe nigitutu kugirango ube PCB laminate.
Ibiciro biva mubisabwa umusaruro pf PCB ubwayo
1. Kurikirana no gutandukanya geometrie-yoroheje ihenze cyane.
2. Kugenzura inzitizi-intambwe yinyongera yongerera ibiciro.
3. Ingano no kubara ibyobo-byinshi hamwe na diametre ntoya itwara ibiciro hejuru.
4. Gucomeka cyangwa kuzuza vias niba ari umuringa utwikiriye - intambwe yinyongera yongerera ibiciro.
5. Umubyimba wumuringa mubice - uburebure buri hejuru bisobanura ibiciro byinshi.
6. Kurangiza hejuru, gukoresha zahabu nubunini bwayo - Ibikoresho byongeweho hamwe nibikorwa byongera ibiciro.
7. Koroherana-kwihanganira gukomera birahenze.
Ibindi bintu bigira ingaruka kubiciro bya PCB
Ibi bintu bito byigiciro birimo icyiciro cya III biterwa na byombi, uwahimbye no gukoresha PCB.Harimo ahanini:
1. Ubunini bwa NPCB.
2.Ubuvuzi butandukanye.
3. guhisha kera.
4. Gucapa imigani.
5. Icyiciro cyimikorere ya PCB (IPC Icyiciro cya II / III nibindi).
6. Ibice bya PCB - byumwihariko kuri z-axis.
7. Kuruhande cyangwa kuruhande.
PCBA izaguha ibitekerezo byiza bikwiranye no kugufasha kugabanya igiciro cyibibaho bya PCB,
