Matambudziko akajairika emhando yebasa reSMT anosanganisira zvikamu zvisipo, zvidimbu zveparutivi, zvikamu zvekuchinja, kutsauka, zvikamu zvakakuvadzwa, nezvimwe.
1. Zvikonzero zvikuru zvekubuda kwechigamba ndeizvi:
① Kudyisa kwechikamu chekudyisa hakusi panzvimbo.
② Nzira yemhepo yechikamu chekusveta muromo yakavharwa, iyo yekusveta muromo yakakuvadzwa, uye kureba kweiyo suction nozzle haina kururama.
③ Iyo vacuum gasi nzira yemidziyo yakashata uye yakavharika.
④ Bhodhi redunhu rapera uye rakaremara.
⑤ Iko hakuna solder paste kana kushoma solder paste padhi redunhu bhodhi.
⑥ Dambudziko remhando yechikamu, ukobvu hwechigadzirwa chimwe chete hachina kuenderana.
⑦ Pane zvikanganiso uye zvakasiirwa mukufona chirongwa cheSMT muchina, kana kusarudzwa zvisirizvo kwechikamu cheukobvu paramita panguva yechirongwa.
⑧ Zvinhu zvevanhu zvakabviswa netsaona.
2. Zvinhu zvikuru zvinoita kuti SMC resistor itendeuke uye mativi emativi ndeaya anotevera
① Kudyisa zvisina kujairika kwechikamu chekudyisa.
② Kureba kwemuromo wekusveta wemusoro unokwira hauna kunaka.
③ Hurefu hwemusoro unokwira hauna kunaka.
④ Saizi yegomba rekudyisa rechikamu chakarukwa chakakurisa, uye chikamu chinotendeuka nekuda kwekudengenyeka.
⑤ Kutungamira kwezvinhu zvakawanda zvakaiswa mubraid zvinodzoserwa kumashure.
3. Zvinhu zvikuru zvinotungamirira kukutsauka kwechiputi zvinotevera
① Iyo XY axis coordination yezvikamu haina kurongeka kana muchina wekuisa wakarongwa.
② Chikonzero chetip suction nozzle ndechekuti zvinhu hazvina kugadzikana.
4. Zvinhu zvikuru zvinotungamira mukukuvadzwa kwezvikamu panguva yekuiswa kwechip ndezvizvi:
① Iyo yekumisikidza thimble yakakwira zvakanyanya, zvekuti chinzvimbo chedunhu bhodhi chakanyanya kukwirira, uye zvikamu zvinodzvanywa panguva yekukwira.
② Iyo z-axis inorongedzerwa yezvikamu haina kurongeka kana muchina wekuisa wakarongwa.
③ Iyo yekusveta nozzle chitubu chemusoro unokwira chakanamira.
