Sanibonani nonke, yimina mhleli.Into eyodwa idinga ukusebenzisa isixhumi ukuze ixhumane nenye into, ngakho-ke kunezixhumi eziningi zebhodi nebhodi ezisizungezile, futhi wonke umuntu uyazi kangcono.Namuhla, ngizoza ngizofunda nawe ukuthi yiziphi izici zobuchwepheshe izixhumi zebhodi ukuya ebhodini ezinazo, kanje:
1. Okokuqala nje, “okuthambile”, ukuxhumana okuguquguqukayo, ukufakwa okulula, kanye nokuqaqa okulula.
2. Ukuphakama okuphansi kakhulu kwesixhumi sebhodi ukuya ebhodini ukunciphisa ubukhulu bomzimba
3. Isakhiwo sokuxhumana sinokumelana okukhulu kwemvelo.Akuyona nje kuphela eguquguqukayo, kodwa futhi yamukela "uxhumano oluqinile" ngokuthembeka okuphezulu kokuxhumana ukuze kuthuthukiswe amandla ahlangene wesokhethi kanye nepulaki.Kulula ukusebenzisa izingxenye zensimbi ezingaguquki kanye nezingxenye zokuxhumana.Indlela yokukhiya, kuyilapho ithuthukisa amandla enhlanganisela, iyenza ixhumeke kakhulu futhi ikhiphe lapho ikhiyiwe
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 eyinhloko enkulu ekuxhumekeni kwe-miniaturization
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.
