Iyini I-Bonding Wire?

Intambo yokubopha iyintambo ehlanganisa izingcezu ezimbili zemishini, ngokuvamile evikela ubungozi. Ukuze ubophe izigubhu ezimbili, kufanele kusetshenziswe ucingo lokubopha, okuwucingo lwethusi oluneziqeshana zengwenya.

I-Gold wire bonding inikezela ngendlela yokuxhumana ngaphakathi kwamaphakheji asebenza ngogesi kakhulu, cishe ukuhleleka kobukhulu obukhulu kunamanye ama-solder. Ngaphezu kwalokho, izintambo zegolide zinokubekezelela okuphezulu kwe-oxidation uma kuqhathaniswa nezinye izinto zocingo futhi zithambile kuneningi, okubalulekile ezindaweni ezibucayi.

I-wire bonding iyinqubo yokudala ukuxhumana kukagesi phakathi kwama-semiconductors (noma amanye amasekhethi ahlanganisiwe) nama-silicon chips kusetshenziswa izintambo zokubopha, okuyizintambo ezinhle ezenziwe ngezinto ezifana negolide ne-aluminium. Izinqubo ezimbili ezivame kakhulu i-golden ball bonding kanye ne-aluminium wedge bonding.

Indlela yokwenza izintambo zokubopha?

Izinqubo zokukhiqiza izintambo ezibophayo:

Iqhaza Legolide Lokubopha Ngocingo Kwezogesi

Emhlabeni wezogesi, kunengxenye ebalulekile edlala indima ebalulekile ekuqinisekiseni ukusebenza nokuthembeka kwemishini kagesi - intambo yegolide. Le nto encane kodwa enamandla ibalulekile ekudaleni ukuxhumana okuyinkimbinkimbi ezingxenyeni ze-elekthronikhi, okuyenza ibe yinto ebalulekile ekwenziweni kwezinto ezihlukahlukene ze-elekthronikhi. Kule bhulogi, sizohlola umhlaba othakazelisayo wentambo yegolide, sihlole izici zayo, izinhlelo zokusebenza, kanye nendima ebalulekile eyidlalayo embonini yezogesi.

Intambo yegolide yokubopha intambo encane eyenziwe ngegolide elimsulwa esetshenziselwa ukwenza ukuxhumana kukagesi phakathi kwe-semiconductor die kanye nephakheji yesekethe ehlanganisiwe. I-conductivity yayo eyingqayizivele, ukumelana nokugqwala, nokuthembeka kuyenza ibe into ekhethwayo ekudaleni lokhu kuxhumana okubalulekile. Ukusetshenziswa kwentambo yegolide yebhondi kuqinisekisa ukuthi amasignali kagesi angageleza kahle nangempumelelo, okunomthelela ekusebenzeni okuphelele nasekuphileni isikhathi eside kwensiza kagesi.

Enye yezinto ezibalulekile zocingo lwegolide oluhlanganisayo oluyenza ibaluleke kakhulu embonini ye-elekthronikhi ukuqhutshwa kwayo okukhethekile. Igolide laziwa ngokusebenza kwalo okuphezulu, okusho ukuthi livumela amasiginali kagesi ukuba adlule ngokumelana okuncane. Lokhu kubalulekile ekuqinisekiseni ukuthi uxhumo olungaphakathi kwezingxenye ze-elekthronikhi lusebenza kahle futhi luthembekile, ekugcineni lube negalelo ekusebenzeni kukonke kwedivayisi. Ukwengeza, igolide limelana kakhulu nokugqwala, okulenza libe into efanelekile yocingo oluyisibopho njengoba likwazi ukumelana nezimo ezibucayi zemvelo izinto zikagesi ezingachayeka kuzo.

Ukufakwa kwentambo yegolide yebhondi kuhlukahlukene futhi kufinyelele kude, kudlula izimboni ezahlukahlukene. Kusukela kuma-electronics abathengi afana nama-smartphones, amaphilisi, namakhompyutha aphathekayo kuya kumishini yezimboni, ugesi wezimoto, nobuchwepheshe be-aerospace, intambo yegolide yebhondi idlala indima ebalulekile ekuqinisekiseni ukusebenza nokuthembeka kwemishini kagesi. Ukusetshenziswa kwayo ezinhlelweni zokusebenza ezinemba okuphezulu lapho ukuthembeka kubaluleke kakhulu kugcizelela ukubaluleka kwalokhu kwaziswa okuncane kodwa okubalulekile.

Enqubweni yokwenziwa kwezinto zikagesi, ukusetshenziswa kwentambo yegolide yokubopha kuyisinyathelo esibalulekile ekudaleni ukuxhumana okuyinkimbinkimbi okwenza idivayisi isebenze ngendlela ehlosiwe. Inqubo ihilela ukubopha ngokucophelela intambo yegolide ku-semiconductor die kanye nephakheji yesekethe ehlanganisiwe, ukuqinisekisa ukuthi ukuxhuma kukagesi kuvikelekile futhi kuthembekile. Le nqubo yokucophelela idinga ukunemba nobungcweti ukuze kuqinisekiswe ukuthi intambo yegolide yokubopha yenza umsebenzi wayo ngokungenasici.

Ukuthembeka kwentambo yegolide yokubopha kubaluleke kakhulu embonini yezogesi, lapho ukusebenza nokuhlala isikhathi eside kwezinto zikagesi kubaluleke kakhulu. Ukusetshenziswa kwentambo yegolide yebhondi kuqinisekisa ukuthi ukuxhunywa kukagesi ocingweni kuhlala kuzinzile futhi kuvikelekile, ngisho nasezimeni zokusebenza ezinzima. Lokhu kwethembeka kubalulekile ezinhlelweni zokusebenza lapho noma yikuphi ukwehluleka ekuxhumekeni kukagesi kungase kube nemiphumela emibi kakhulu, njengakumadivayisi ezokwelapha, ubuchwepheshe be-aerospace, kanye nogesi wezimoto.

Iqhaza lentambo yegolide yokubopha embonini ye-elekthronikhi idlulela ngalé kwezakhiwo zayo ezibonakalayo kanye nezicelo. Iphinde futhi imele isiphetho sobuchwepheshe obuthuthukile nobunjiniyela obunembayo, lapho yonke imakhroni yocingo lwegolide iklanywe ngokucophelela futhi yakhiwe ukuze ihlangabezane nezindinganiso eziqondile zomkhakha. Inqubekelaphambili eqhubekayo ekukhiqizeni nasekusetshenzisweni kwentambo yegolide yebhondi ibonisa ukuphishekela okungapheli kokwenza kahle embonini yezogesi, lapho ukwethembeka nokusebenza kungaxoxiswana ngakho.

Njengoba isidingo semishini ye-elekthronikhi emincane, esheshayo, futhi enokwethenjelwa kakhudlwana siqhubeka sikhula, indima yocingo oluyigolide iba ngobaluleke nakakhulu. Ukwenziwa okuncane kwezingxenye ze-elekthronikhi kanye nobunkimbinkimbi obukhulayo bezinto zikagesi zidinga izinto ezingahlangabezana nezidingo eziqinile zobuchwepheshe besimanje. Intambo yegolide yokubopha, enokwethenjelwa kwayo, ukwethembeka, kanye nokumelana nokugqwala, ibekwe kahle ukuze ihlangabezane nalezi zidingo futhi iqhubeke nokudlala indima ebalulekile ekuthuthukisweni kwemboni yezogesi.

Sengiphetha, intambo yegolide iyinto encane kodwa ebaluleke kakhulu edlala indima ebalulekile embonini yezogesi. I-conductivity yayo eyingqayizivele, ukwethembeka, kanye nokumelana nokugqwala kuyenza ibe yinto ekhethwayo ekwakheni ukuxhumana okuyinkimbinkimbi ngaphakathi kwezingxenye ze-elekthronikhi. Kusukela kuma-elekthronikhi omthengi ukuya kuzinhlelo zokusebenza zezimboni ezinemba okuphezulu, ukusetshenziswa kwentambo yegolide yebhondi kuqinisekisa ukuthi izinto zikagesi zisebenza ngokwethembeka nangempumelelo. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, indima yentambo yegolide izohlala ibalulekile ekulolongeni ikusasa lemboni yezogesi, lapho ukuphishekela ubuhle nokuthembeka kubaluleke kakhulu.
