- Gucukura inyuma ni iki?
Gucukura inyuma ni ubwoko bwihariye bwo gucukura umwobo. Mu musaruro wibibaho byinshi, nkibibaho 12, dukeneye guhuza urwego rwa mbere nu cyenda. Mubisanzwe, ducukura umwobo (umwitozo umwe) hanyuma tukarohama umuringa. Muri ubu buryo, igorofa ya mbere ihuzwa na etage ya 12. Mubyukuri, dukeneye gusa igorofa ya mbere kugirango duhuze igorofa ya 9, na etage ya 10 kugeza muri etage ya 12 kuko nta murongo uhuza, nkinkingi. Iyi nkingi igira ingaruka kumuhanda wikimenyetso kandi irashobora gutera ibibazo byubusugire bwibimenyetso muri ibimenyetso byitumanaho. Noneho rero, kora inkingi yumurengera (STUB mu nganda) uhereye kuruhande (drill ya kabiri) .Nuko rero bita imyitozo yinyuma, ariko mubisanzwe ntabwo ari umwitozo usukuye cyane, kuko inzira izakurikiraho izahindura electrolysis kumuringa muto, hamwe ninama ya drill ubwayo irerekanwa. Kubwibyo, uruganda rwa PCB ruzasiga ingingo nto. Uburebure bwa STUB bwiyi STUB bwitwa B agaciro, mubusanzwe buri hagati ya 50-150um.
2.Ibyiza byo gucukura inyuma
1) kugabanya kwivanga kw urusaku
2) kuzamura ubunyangamugayo bwibimenyetso
3) uburebure bwa plaque yaho buragabanuka
4) kugabanya ikoreshwa ryimyobo ihumye kandi bigabanya ingorane zumusaruro wa PCB.
3. Gukoresha gucukura inyuma
Tugarutse ku myitozo imyitozo ntaho yari ihuriye cyangwa ingaruka zumwobo, irinde gutera kugaragariza ibimenyetso byihuta byohereza ibimenyetso, gutatanya, gutinda, nibindi, bizana ibimenyetso "kugoreka" ubushakashatsi bwerekanye ko nyamukuru ibintu bigira ingaruka kuri sisitemu yerekana ibimenyetso byerekana uburinganire, ibikoresho bya plaque, hiyongereyeho ibintu nkumurongo wohereza, umuhuza, ipaki ya chip, umwobo uyobora bigira ingaruka nini mubusugire bwibimenyetso.
4. Ihame ryakazi ryo gucukura inyuma
Iyo urushinge rwa drillage rurimo gucukura, micro ya micro ikorwa mugihe urushinge rwimyitozo ruhuye numuringa wumuringa hejuru yicyapa cyibanze bizatera uburebure bwa plaque, hanyuma imyitozo izakorwa ukurikije ubujyakuzimu bwashyizweho, kandi imyitozo izahagarikwa mugihe ubujyakuzimu bugeze.
5.Gusubiza inyuma uburyo bwo kubyaza umusaruro
1) gutanga PCB hamwe nu mwobo wigikoresho. Koresha umwobo wibikoresho kugirango ushire PCB hanyuma ucukure umwobo;
2) amashanyarazi PCB nyuma yo gucukura umwobo, no gufunga umwobo na firime yumye mbere yo gutanga amashanyarazi;
3) gukora ibishushanyo mbonera byo hanze kuri PCB amashanyarazi;
4) kuyobora amashanyarazi kuri PCB nyuma yo gukora igishushanyo mbonera, no gukora firime yumye ifunga umwobo uhagaze mbere yo gushushanya amashanyarazi;
5) koresha umwobo uhagaze ukoreshwa numwitozo umwe kugirango ushire umwitozo winyuma, hanyuma ukoreshe icyuma cyimyitozo kugirango usubize inyuma umwobo wa electroplating ukeneye gusubira inyuma;
6) koza inyuma yo gucukura nyuma yo gucukura inyuma kugirango ukureho ibisigazwa bisigaye mu gucukura inyuma.
6. Ibiranga tekiniki biranga isahani yo gucukura inyuma
1) Ikibaho gikomeye (benshi)
2) Mubisanzwe ni 8 - 50
3) Ubunini bwibibaho: hejuru ya 2,5mm
4) Uburebure bwa diameter ni bunini
5) Ingano yubuyobozi ni nini
6) Umurambararo ntarengwa wa diameter ya myitozo ya mbere ni> = 0.3mm
7) Umuzunguruko wo hanze ugereranije, igishushanyo mbonera cya kwaduka
8) Umwobo winyuma mubusanzwe ufite 0.2mm nini kuruta umwobo ugomba gucukurwa
9) Kwihanganira ubujyakuzimu ni +/- 0.05mm
10) Niba imyitozo yinyuma isaba gucukura kugeza kuri M, ubunini bwikigereranyo hagati ya M na m-1 (urwego rukurikiraho rwa M) bizaba byibuze 0.17mm
7.Ikoreshwa ryibanze rya plaque yinyuma
Ibikoresho byitumanaho, seriveri nini, ibikoresho bya elegitoroniki yubuvuzi, igisirikare, ikirere nizindi nzego. Kubera ko igisirikare n’ikirere ari inganda zoroshye, Indege yimbere mu gihugu isanzwe itangwa nikigo cyubushakashatsi, ubushakashatsi niterambere ryiterambere rya sisitemu ya gisirikari nindege cyangwa inganda za PCB zifite ingufu zikomeye za gisirikare nindege.Mu Bushinwa, icyifuzo cyindege kiva mubitumanaho inganda, none uruganda rukora ibikoresho byitumanaho rugenda rutera imbere.
