Uguquko lwezisekelo zemishini yokuhlola i-semiconductor AOI: I-Granite inokucindezelwa kokudlidliza okuphezulu okungama-92% kune-cast iron.

.
Emkhakheni wokukhiqiza ama-semiconductor, okokusebenza kwe-automatic Optical inspection (AOI) kudlala indima ebalulekile ekuqinisekiseni ikhwalithi yamashiphu. Ngisho nokuthuthukiswa okuncane ekuboneni kwayo kungaletha uguquko olukhulu kuyo yonke imboni. Isisekelo semishini, njengengxenye eyinhloko, sinomthelela omkhulu ekunembeni kokutholwa. Eminyakeni yamuva nje, uguquko lwezinto eziyisisekelo luye lwahlasela imboni. I-Granite, ngokusebenza kwayo okuvelele kokucindezela ukudlidliza, kancane kancane ithathe indawo yezinto zensimbi ezisansimbi evamile futhi yaba intandokazi entsha yempahla yokuhlola ye-AOI. Ukusebenza kahle kwayo kokucindezela ukudlidliza kukhuphuke ngo-92% uma kuqhathaniswa nensimbi ekhonjiwe. Yikuphi ukuthuthuka kwezobuchwepheshe kanye nezinguquko zemboni ezilele ngemuva kwale datha? .
Izidingo eziqinile zokudlidliza kumpahla yokuhlola ye-semiconductor AOI
Inqubo yokukhiqiza ama-semiconductor chips isingene enkathini ye-nanoscale. Ngesikhathi senqubo yokuhlola i-AOI, ngisho nokudlidliza okuncane kakhulu kungabangela ukuchezuka emiphumeleni yokuhlola. Ukuklwebheka okuhle, ama-voids nokunye ukukhubazeka okungaphezulu kwe-chip kuvame ukuba ku-micrometer noma ezingeni le-nanometer. Amalensi okubona okokusebenza okutholayo adinga ukuthwebula le mininingwane ngokunemba okuphezulu kakhulu. Noma yikuphi ukudlidliza okudluliselwa isisekelo kuzobangela ukuthi ilensi inyakaze noma inyakaze, okuholela ekutholweni kwesithombe esilufifi futhi ngaleyo ndlela kuthinte ukunemba kokubonwa kokukhubazeka.
Izinto zensimbi ezisansimbi zake zasetshenziswa kakhulu ezisekelweni zemishini yokuhlola ye-AOI ngenxa yokuthi zinamandla athile nokusebenza kokucubungula, futhi izindleko ziphansi uma kuqhathaniswa. Kodwa-ke, mayelana nokucindezelwa kokudlidliza, insimbi ekhonjiwe inamaphutha asobala. Isakhiwo sangaphakathi se-cast iron siqukethe inani elikhulu lamashidi e-graphite, alingana nama-voids amancane ngaphakathi futhi aphazamise ukuqhubeka kwezinto. Lapho okokusebenza kusebenza futhi kukhiqiza ukudlidliza, noma kuphazanyiswa ukudlidliza kwemvelo kwangaphandle, amandla okudlidliza awakwazi ukuncishiswa ngokuphumelelayo kunsimbi ekhonjiwe kodwa aboniswa njalo futhi abekwe phezulu phakathi kweshidi legraphite ne-matrix, okuholela ekusakazekeni okuqhubekayo kokudlidliza. Ukuhlola okuhlobene kukhombisa ukuthi ngemuva kokuthi isisekelo se-cast iron sijatshuliswe ukudlidliza kwangaphandle, isikhathi sokudlidliza singahlala amasekhondi ambalwa, okuzoba nomthelela ongathi sína ekutholeni ukunemba ngalesi sikhathi. Ngaphezu kwalokho, i-elastic modulus ye-cast iron iphansi kakhulu. Ngaphansi kwesenzo sesikhathi eside sezinto zokusebenza amandla adonsela phansi kanye nengcindezi yokudlidliza, ijwayele ukuguquguquka, iqinise ukudluliswa kokudlidliza. .
Imfihlo ngemuva kokwenyuka okungu-92% ekusebenzeni kahle kokucindezelwa kokudlidliza kwezisekelo zegwadle

I-Granite, njengohlobo lwetshe lemvelo, yenze isakhiwo sangaphakathi esiminyene kakhulu nesifanayo ngokusebenzisa izinqubo ze-geological phakathi namakhulu ezigidi zeminyaka. Ngokuyinhloko yakhiwa amakristalu amaminerali afana ne-quartz ne-feldspar ehlangene eduze, futhi izibopho zamakhemikhali phakathi kwamakristalu ziqinile futhi zizinzile. Lesi sakhiwo sinikeza i-granite ikhono elivelele lokucindezela ukudlidliza. Uma ukudlidliza kudluliselwa kusisekelo segranite, amakristalu amaminerali ngaphakathi kuyo angaguqula ngokushesha amandla okudlidliza abe amandla okushisa futhi awachithe. Ucwaningo lubonisa ukuthi ukufiphala kwegwadle kuphakeme ngokuphindwe izikhathi eziningana kunokwensimbi ecijile, okusho ukuthi ingakwazi ukumunca amandla okudlidliza kahle, inciphise ubude nobude besikhathi sokudlidliza. Ngemuva kokuhlolwa kochwepheshe, ngaphansi kwezimo ezifanayo zokudlidliza, isikhathi sokunciphisa ukudlidliza kwesisekelo segwadle singama-8% kuphela aleso lensimbi ekhonjiwe, futhi ukusebenza kahle kokucindezela ukudlidliza kwenyuke ngo-92%. .
Ukuqina okuphezulu kanye ne-modulus ephezulu yokunwebeka ye-granite nakho kunomthelela omkhulu. Ukuqina okuphezulu kuqinisekisa ukuthi isisekelo mancane amathuba okuba siwohloke lapho sithwala isisindo sezinto zokusebenza kanye nemithelela yamandla angaphandle, futhi ngaso sonke isikhathi sigcina isimo sokusekela esizinzile. Imodulus enwebekayo ephezulu iqinisekisa ukuthi isisekelo singabuyela ngokushesha esimeni saso sangempela uma singaphansi kokudlidliza, sinciphisa ukunqwabelana kokudlidliza. Ukwengeza, i-granite inokuzinza okuhle kakhulu kokushisa futhi ayithinteki ekushintsheni kwezinga lokushisa kwemvelo, igwema ukwanda kokushisa kanye nokuguqulwa kokuncipha okubangelwa ukushintshashintsha kwezinga lokushisa, ngaleyo ndlela iqinisekise ukuqina kokusebenza kokucindezela ukudlidliza. .
Uguquko Lwemboni kanye Namathemba Alethwa yizisekelo zegwadle
Imishini yokuhlola ye-AOI enesisekelo segwadle ithuthukise ngokuphawulekayo ukunemba kwayo kokutholwa. Ingahlonza ngokuthembekile iziphambeko kuma-chips anosayizi omncane, yehlise izinga lokungahluleli libe phakathi kuka-1% futhi ithuthukise kakhulu izinga lokukhiqiza lokukhiqizwa kwama-chip. Khonamanjalo, ukuzinza kwezisetshenziswa kuthuthukisiwe, kwehliswa isibalo sokuvalwa kokulungiswa okubangelwa izinkinga zokudlidliza, ukwelula isikhathi sesevisi yezinto zokusebenza, nokwehliswa kwazo zonke izindleko zokusebenza. .
