- Gucukura inyuma ni ubuhe?
Gusubira inyuma ni ubwoko bwihariye bwumwobo wimbitse. Mu gukora ibibaho byinshi, nkimbaho-12-lager, dukeneye guhuza igice cya mbere kugeza ku cyiciro cya cyenda. Mubisanzwe, dukuramo umwobo (drill imwe) hanyuma tukarohama umuringa.in Mubyukuri, dukeneye igorofa ryambere kugirango duhuze kuri etage ya 9, hamwe na etage ya 10 kugeza ku igorofa rya 12 kuko nta murongo uhuza ibimenyetso byubuturo. Amashanyarazi ava muri umuringa muto, kandi inkingi ubwayo yerekana.Nuko rero, uruganda rwa PCB ruzasiga ingingo nto. Uburebure bwa Stub bwiyi stub bwitwa b agaciro, muri rusange muri 50-150um.
2.Ibyiza byo gucukura inyuma
1) kugabanya kwivanga urusaku
2) Kunoza Ubunyangamugayo
3) Icyapa cyaho kigabanuka
4) Kugabanya imikoreshereze yashyinguwe umwobo no kugabanya ingorane zumusaruro wa PCB.
3. Imikoreshereze yo gucukura inyuma
Subira kuri Drill Loll ntabwo yari afite aho ihuriye cyangwa ingaruka z'igice cy'imyuga, irinda ko ubushakashatsi bwihuse bwo kwanduza ibimenyetso, ibimenyetso, ibiganiro, kugoreka, kunesha umwuka bifite ingaruka nini ku bunyangamugayo.
4. Ihame ryakazi ryo gucukura
Igihe urufunguzo rufunze rurimo gucukura, micro ubungubu iyo imyitozo ifite umuyoboro urufunguzo rw'umuringa azashimangira ubujyakuzimu bw'isahani, hanyuma imyitozo izahagarara iyo ubujyakuzimu bugerwaho.
5.Gukemura ibibazo
1) Tanga PCB hamwe nu mwobo. Koresha umwobo wibikoresho kugirango ushyire PCB hanyuma ugacukura umwobo;
2) Amashanyarazi ya PCB nyuma yo gucukura umwobo, hanyuma akadoda umwobo hamwe na firime yumye mbere yuko electraplating;
3) kora ibishushanyo byo hanze kuri PCB ya electhlaplated;
4) Gukora amashusho ya electraplating kuri PCB nyuma yo gukora icyiciro cyo hanze, hanyuma ukore icyapa cyumye cyumwobo uhagaze mbere yicyitegererezo;
5.
6) Karaba umugongo nyuma yo gucukura kugirango ukureho ibishishwa bisinze inyuma.
6. Ibiranga tekiniki byo gucukura isaha
1) Ubuyobozi bukomeye (benshi)
2) Mubisanzwe ni 8 - 50
3) Ubunini: hejuru ya 2.5mm
4) Ubunini bwa diameter ni kinini
5) Ingano yinama ni nini
6) Imyumbati ntarengwa ya drill yambere ni> = 0.3mm
7) Inzego zo hanze nke, igishushanyo mbonera cya kare kugirango umwobo
8) Umwobo winyuma mubisanzwe 0.2mm nini kuruta umwobo ukeneye gucukurwa
9) Kwihanganira ubujyakuzimu ni +/- 0.05mm

7.Ibisanzwe byo gutunganya isahani yo gucukura
Ibikoresho byitumanaho, seriveri nini, ibikoresho bya elegitoroniki, igisirikare, aeropace nibindi bice. Mugihe igisirikare na Aerospace ari inganda zumvaga, nyuma yinyuma yinyuma iteganijwe n'ikigo cy'ubushakashatsi, mu gihe cy'iterambere ry'igisirikare na aerospace. Ubushinwa, none abakora ibikoresho by'itumanaho.
