Izinkinga ezijwayelekile zekhwalithi yomsebenzi we-SMT okufaka izingxenye ezingekho, izingcezu eziseceleni, izingxenye zenzuzo, ukuchezuka, izingxenye ezilimele, njll.
1. Izimbangela eziyinhloko zokuvuza kwesichibi yilezi ezilandelayo:
① Ukuphakelwa kwengxenye yesiphakeli akukho endaweni.
② Indlela yomoya yomlomo wokumunca ingxenye ivinjiwe, umbhobho wokumunca wonakele, nobude bombhobho wokumunca abulungile.
③ Indlela yegesi ye-vacuum yemishini inephutha futhi ivinjiwe.
④ Ibhodi lesifunda liphelile futhi likhubazekile.
⑤ Akukho ukunamathisela kwe-solder noma ukunamathisela kwe-solder okuncane kakhulu kuphedi yebhodi lesifunda.
⑥ Inkinga yekhwalithi yengxenye, ukujiya komkhiqizo ofanayo akuhambisani.
⑦ Kunamaphutha kanye nokweqiwa ohlelweni lokushaya ucingo lomshini we-SMT, noma ukukhetha okungalungile kwamapharamitha wokuqina kwengxenye ngesikhathi sohlelo.
⑧ Izici zomuntu zisuswe ngephutha.
2. Izinto eziyinhloko ezidala ukuthi i-SMC resistor iphenduke kanye nezingxenye ezisemaceleni zimi kanje
① Ukuphakelwa okungavamile kwengxenye yesiphakeli.
② Ubude bomlomo wokumunca wekhanda elikhuphukayo abulungile.
③ Ubude bekhanda elifakwayo abulungile.
④ Usayizi wembobo yokuphakela yengxenye yomluko mkhulu kakhulu, futhi ingxenye iyajika ngenxa yokudlidliza.
⑤ Isiqondiso sempahla eyinqwaba efakwe kumluko siyahlehliswa.
3. Izici eziyinhloko eziholela ekuphambukeni kwe-chip yilezi ezilandelayo
① Izixhumanisi ze-XY axis zezingxenye azilungile uma umshini wokubeka uhlelwa.
② Isizathu sokumunca ithiphu ukuthi into ayizinzile.
4. Izinto eziyinhloko eziholela ekulimaleni kwezingxenye ngesikhathi sokubekwa kwe-chip zimi kanje:
① I-thimble yokumisa iphezulu kakhulu, ukuze indawo yebhodi lesekethe iphakame kakhulu, futhi izingxenye ziyampintsha ngesikhathi sokukhuphuka.
② Izixhumanisi ze-z-axis zezingxenye azilungile uma umshini wokubeka uhlelwa.
③ Umthombo womlomo wokumunca wekhanda elikhuphukayo ubhajwe.
