I-SMD izoba nezinkinga ezihlukahlukene zekhwalithi ezenzekayo, isibonelo, ingxenye yohlangothi lwe-solder engenalutho esontekile, imboni ebizwa ngokuthi lesi simo setshe lesikhumbuzo.
Omunye umkhawulo wengxenye wasonta kanjalo okubangela lesikhumbuzo solder ezingenalutho, kuba ezihlukahlukene izizathu ukwakheka.Namuhla, sizochaza izimbangela zalesi simo kanye nezinyathelo ezithile zokuthuthukisa.
1.Iphrinta yokunamathisela ye-solderayisicaba, enye ingxenye yephedi iyithayela eningi, enye ingxenye encane ithini
Lona umkhawulo wangaphambili we-patch wabangela, ngenxa yokuphrinta kokunamathisela kwe-solder ongalingani, ukuphrinta kwe-solder unamathisele emikhawulweni yomibili ye-pad akuyona inani elifanayo, okuholela ngemuva kwesikhathi sokuchithwa kwe-welding akufani, okubangela ukungezwani akufani, futhi ngaleyondlela enye ingxenye yasonteka ukuze yenze i-solder engenalutho.
Indlela engcono kakhulu yokuthuthukisa lokhu ukwengeza i-SPI ngemuva komshini wokuphrinta we-solder unama, zama ukuthola ukuphrinta okubi, ukugwema ukugeleza kuya ekushiseleni bese kuba nenkinga, ukuze isikhathi sokusebenza kabusha sidle futhi izindleko ziphezulu.
2.Khetha bese ubeka umshiniukukhweza iziphetho zombili azishintshile noma azihlangani
Ngemva kweUmshini we-SMDimunca ukubekwa kwengxenye, ingase ibangele ukuthi umlomo wombhobho wokumunca umunce ukuchezuka noma ikhamera ifunde ukunemba kokubekwa kwenombolo kancane ukuze iphambuke ngenxa yokuphakelayo kweflaya, ngaleyo ndlela kuholele ekubekweni kwe-offset, isiphetho sephedi sithunyelwe ngaphezulu, isiphetho esisodwa okuthunyelwe okuncane ukuze kuvezwe ku-pad ngaphandle, ngaleyo ndlela kuholele esikhathini sokushisela kabusha lapho isikhathi sokuncibilika esishisayo sihlukile, isikhathi sokukhuphuka se-tin sihlukile, okuholela ekucindezelekeni okuhlukene, okubangela ukungqubuzana.
Indlela yokuthuthukisa le nkinga, ngakolunye uhlangothi ukugcina iflaya ye-mounter nekhamera njalo, ukugwema ukumunca nokubeka ukuchezuka.ngakolunye uhlangothi, kunesabelomali sokuthola aUmshini we-SMT AOI, thola ikhwalithi yokubeka.
3.Reflow soldering umshiniinkinga yokusetha ijika lokushisa kwesithando somlilo
I-Reflow soldering ngokwayo inezindawo ezine zokushisa, indima ehlukene yendawo yokushisa ihlukile, ekushiseni nasesiteji sokushisa okuqhubekayo, ezinye izingxenye zingase zibekwe eduze kwezingxenye eziphakeme, ngaleyo ndlela zibangele ukuthi uhlangothi olulodwa lushiswe kabi, ekungeneni kwesiteji sokushisa ukushisa, izinga lokushisa lihlukile okuholela ku-solder unama ukushisa isikhathi sokuncibilika kwehlukile, ukubonakala kwesikhumbuzo sokuma kwe-welding engenalutho.
Izizathu ezintathu ezingenhla ziyizimbangela ezivamile zezingxenye ezisontekile zethebhulethi emile engenalutho, uma inqubo yokukhiqiza, lesi simo singavela kulezi zici zokuxazulula inkinga.
