Sanibonani nonke, yimina mhleli.Into eyodwa idinga ukusebenzisa isixhumi ukuze ixhumane nenye into.Ngakho-ke, kunezixhumi eziningi zebhodi kuya ebhodini ezisizungezile, futhi wonke umuntu uyazi kangcono.Namuhla, umhleli uzofunda nawe ukuthi yiziphi izici zobuchwepheshe izixhumi zebhodi ukuya ebhodini ezinazo, kanje:
1. Okokuqala, "ithambile", uxhumano oluguquguqukayo, kulula ukuyifaka futhi kulula ukuyihlakaza.
2. Ukuphakama okuphansi kakhulu kwesixhumi sebhodi ukuya ebhodini ukuze kufezwe injongo yokunciphisa ukujiya komzimba.
3. Isakhiwo sokuxhumana sinokumelana okukhulu kwemvelo.Akuyona nje kuphela eguquguqukayo, kodwa futhi isebenzisa "uxhumano oluqinile" ngokuthembeka okuphezulu kokuxhumana ukuze kuthuthukiswe amandla ahlangene wesokhethi kanye nepulaki.Kulula ukusebenzisa izingxenye zensimbi ezingaguquki kanye nezingxenye zokuxhumana.Indlela yokukhiya, ngenkathi ithuthukisa amandla enhlanganisela, iyenza ixhumeke kakhulu futhi ikhiphe lapho ikhiya
4. Ukuze kuhlangatshezwane nezidingo zenqubo ye-SMT, indawo yokushisela esibulalayo yawo wonke umkhiqizo idingeka ngokuqinile ukuze ibe ne-coplanarity enhle.
5. Isixhumi sebhodi ukuya ebhodini emincane kakhulu sibeka phambili izidingo ezintsha zenqubo ye-electroplating.Ungaqinisekisa kanjani ukuthi ukujiya kwegolide komkhiqizo kanye nomthelela we-tinning akukhuphuki uthayela, sekuyinkinga enkulu kakhulu ekuhlanganiseni okuncane kwesixhumi
6. Isixhumi sebhodi ukuya ebhodini singakhelwa umklamo wesekethe womshini olula.Ngokuhlinzeka ngodonga oluvikelayo endaweni engaphansi yesixhumi, i-PCB board trace kanye netheminali yensimbi ingahanjiswa futhi ifakwe izintambo endaweni engaphansi yesixhumi ngaphandle kokuxhumana, okuzuzisa kakhulu ukwenziwa kancane kwebhodi le-PCB.
7. Ukuhlanganisa isiqondiso senqubo.Ngokuthuthuka kwezikhathi, ziya ngokuya zisetshenziswa izixhumi ezincane.Ngakho-ke, lapho uhlanganisa, kufanele uqondanise i-engeli yesingeniso bese uyicindezela phansi kanzima ukuze ugweme ukulimala komkhiqizo okubangelwa ukugudluka nokucindezela.
