Ngenqubo yokusebenza kwe-SMT Chip,umjikelezo omfushaneyinto engcono kakhulu yokusebenza kabi. Ibhodi yesekethe ye-PCBA ezuziwe ayikwazi ukusetshenziswa ngokujwayelekile. Okulandelayo yindlela evamile yokuhlola yesifunda esifushane se-PCBA Board.

1. Kunconywa ukusebenzisa i-Analyzer Emjikelezayo Emfushane ukuhlola isimo esingesihle.

2. Uma kwenzeka inani elikhulu lemibuthano emifushane, kunconywa ukuthatha ibhodi yesekethe ukusika izintambo, bese kuba namandla endaweni ngayinye ukubheka izindawo ezinemibuthano emifushane ngamunye ngamunye.

I-3. Kunconywa ukusebenzisa i-multimeter ukuthola ukuthi umjikelezo osemqoka umzuzwana? Njalo lapho isichibi le-SMT seliqediwe, i-IC idinga ukusebenzisa i-multimeter ukuthola ukuthi ngabe ukuhanjiswa kwamandla nangokwesekeli kunciphisiwe?

4. Khanyisa inethiwekhi yesifunda emfushane kumdwebo we-PCB, hlola isikhundla ebhodini lesekethe lapho umjikelezo omfushane kungenzeka kakhulu, futhi unakekele ukuthi ngabe kukhona umjikelezo omfushane ngaphakathi kwe-IC.

6 Uma kwenzeka umjikelezo omfushane, ukunqamulani kokutholwa kobubanzi kazibuthe kuzokwenza kube lula ukuthola i-chip kwibhodi yesekethe.
