Ukuthenga abasebenzi ngesikhathi sokuthenga, banenkinga yokukhetha isixhumi, njengesidingo sokucabangela isivinini sokudlulisela, ubuqotho besignali, izinkinga zokusebenza, njengosayizi nokuma, kodwa isidingo esikhulu sokubangela ukukhathazeka kwethu ukunquma indlela yokuqeda isixhumi, lokhu kungenxa yokuthi izinhlelo zokusebenza eziningi zidinga uhlobo oluthile lobuchwepheshe ukuze lufane nezidingo zokuklama isixhumi, Ngakho-ke yiziphi ubuchwepheshe bokugcina besixhumi?
Ubuchwepheshe bokunqamula isixhumi ikakhulukazi buhlanganisa ubuchwepheshe be- through-hole terminating (THT), ubuchwepheshe be-surface mount terminating (SMT), ubuchwepheshe bokunqamula i-pin through-hole reflow welding, kanye nobuchwepheshe bokunqamula obuhambisana nokucindezela.Imininingwane imi kanje:
1, isixhumi ngokusebenzisa ubuchwepheshe bokuqeda imbobo (THT).
Ukunqanyulwa kwembobo kwakuvamile ezinsukwini zokuqala, izixhumi ezithinta noma eziholela emigodini ku-PCB.Izingxenye zembobo zifaneleka kangcono emikhiqizweni enokwethenjelwa kakhulu edinga ukuxhumana okuqinile phakathi kwezendlalelo ze-PCB.
2, ubuchwepheshe be-surface mount end (SMT) ubuchwepheshe
Ukusetshenziswa kokuqedwa kwe-surface-mount yalobu buchwepheshe, isixhumi singafakwa ngqo phezu kwe-PCB kanye ne-manual welding endaweni, futhi singasebenzisa izindlela zokuphinda zifakwe / ze-wave soldering kufanele zimiswe endaweni.
3, iphinikhodi yesixhumi ngokusebenzisa ubuchwepheshe bokuphela kwe-hole reflow welding
I- through hole reflow welding end technology yesixhumi igcwaliswa ikakhulukazi ngemishini ezenzakalelayo, ngaphandle kwenqubo ye-manual kanye ne-wave soldering.Izixhumi azigxili ngokukhululekile emigodini yepuleti futhi zibekwe ngaphansi komshini ukuze i-solder enoketshezi igeleze ibuyele epuletini ngezinga lokushisa eliphezulu.Ngenxa yesenzo se-capillary, i-solder paste encibilikisiwe idonsa i-solder epuleti futhi ingene emgodini, yenza isibopho esihlala njalo phakathi kwe-solder paste kanye nemikhondo yokuxhuma, bese i-solder esele isusiwe.
4, ingcindezi yesixhumi ehambisana nobuchwepheshe bokuphela
Ukunqanyulwa kokulinganisa ukucindezela kuvame ukuthengiswa, okusiza ukwehlisa izindleko eziphelele zezinhlelo zokusebenza zesixhumi, futhi ngokuvamile kuyanconywa ukusebenzisa lezi zinhlobo zezixhumi ngamathuluzi athile ukuze kuqinisekiswe ukuthi izinto zifakwa ngokulinganayo futhi endaweni yazo ngokugcwele.
