Guhuza insinga ni iki?

Guhuza insinga nuburyo bwo gukoresha uburebure bwa diametre ntoya ya insinga yicyuma ifatanye hejuru yicyuma kijyanye no gukoresha ibicuruzwa, flux, kandi hamwe na hamwe hakoreshejwe ubushyuhe buri hejuru ya dogere selisiyusi 150. Ibyuma byoroshye birimo Zahabu (Au), Umuringa (Cu), Ifeza (Ag), Aluminium (Al) hamwe n'amavuta nka Palladium-Ifeza (PdAg) n'ibindi.

Gusobanukirwa Uburyo bwo Guhuza Uburyo hamwe nuburyo bukoreshwa muri Micro Electronics Inteko.
Uburyo bwo Guhuza Umuyoboro / Inzira: Inzira, Umupira wa Thermosonic & Ultrasonic Wedge Bond
Guhuza insinga nuburyo bwo gukora imiyoboro hagati yumuzunguruko (IC) cyangwa igikoresho gisa na semiconductor hamwe na pack yayo cyangwa gurşframe mugihe cyo gukora. Irakoreshwa kandi ubu kugirango itange amashanyarazi mumateraniro ya batiri ya Litiyumu-ion. Guhuza insinga mubisanzwe bifatwa nkigiciro cyinshi kandi cyoroshye muburyo bwa tekinoroji ya micrélectronique ihari, kandi ikoreshwa mubikoresho byinshi bya semiconductor byakozwe muri iki gihe.Hariho ni tekinike nyinshi zo guhuza insinga, zigizwe na: Thermo-Compression Wire Bonding:
Guhuza insinga ya Thermo-compression (ikomatanya hejuru yubusanzwe (ubusanzwe Au) hamwe munsi yingufu zifatika hamwe nubushyuhe bwo hejuru, ubusanzwe burenga 300 ° C, kugirango habeho gusudira), bwatangiye gukorwa mumwaka wa 1950 kugirango mikorobe ihuza imiyoboro, nyamara ibi byari byihuse gusimburwa na Ultrasonic & Thermosonic guhuza muri za 60 nkikoranabuhanga ryiganje. Guhuza Thermo-compression biracyakoreshwa muburyo bukoreshwa muri iki gihe, ariko muri rusange birindwa nababikora bitewe nubushyuhe bwo hejuru (akenshi bwangiza) ubushyuhe bukenewe kugirango ubashe gukora neza.Ultrasonic Wedge Wire Bonding:
Mu myaka ya za 1960 Ultrasonic wedge wire ihuza uburyo bwiganje muburyo bwo guhuza imiyoboro. Gukoresha umuvuduko mwinshi cyane (ukoresheje transducer yumvikana) mugikoresho cyo guhuza hamwe nimbaraga zo gufatira icyarimwe, byemerera insinga za Aluminium na Zahabu gusudira mubushyuhe bwicyumba. Ihindagurika rya Ultrasonic rifasha mu gukuraho umwanda (oxyde, umwanda, nibindi) hejuru yubusabane mugitangira cyuzuzanya, no mugutezimbere gukura hagati kugirango urusheho gutera imbere no gushimangira ubumwe. Imirongo isanzwe yo guhuza ni 60 - 120 KHz.Ubuhanga bwa ultrasonic wedge tekinike ebyiri zingenzi zikoreshwa muburyo bukomeye: Umuyoboro munini (uremereye) uhuza insinga za diametre 100µmFine (ntoya) guhuza insinga za <75µm diameter insingaUrugero rwibisanzwe bisanzwe bya Ultrasonic. ku nsinga nziza na hano ku nsinga nini. Guhuza insinga ya Ultrasonic ikoresha igikoresho cyihariye cyo guhuza cyangwa “wedge,” ubusanzwe cyubatswe muri Tungsten Carbide (kuri wire ya Aluminium) cyangwa Titanium Carbide (kuri wire ya Zahabu) bitewe nibisabwa hamwe na diameter; ceramic tipged wedges kubisabwa bitandukanye birahari kandi.Termosonic Wire Bonding:
Iyo hakenewe ubushyuhe bwinyongera (mubisanzwe kuri wire ya Zahabu, hamwe nintera ihuza intera iri hagati ya 100 - 250 ° C), inzira yitwa Thermosonic wire bonding. Ibi bifite ibyiza byinshi kurwego rwa gakondo ya thermo-compression, nkuko ubushyuhe bwo hasi busabwa (Au guhuza ubushyuhe bwicyumba byavuzwe ariko mubikorwa ntabwo byizewe nta bushyuhe bwiyongereye) .Guhuza umupira wa Termosonic:
Ubundi buryo bwo guhuza insinga za Thermosonic ni Ball Bonding (reba umupira uhuza umupira hano). Ubu buryo bukoresha ceramic capillary igikoresho cyo guhuza hejuru ya gakondo ya wedge kugirango uhuze imico myiza haba muri thermo-compression hamwe na ultrasonic guhuza nta nkomyi. Kunyeganyega kwa Thermosonic byemeza ko ubushyuhe bwimbere buguma ari buke, mugihe ihuriro ryambere, guhuza imipira yubushyuhe bwumuriro butuma insinga nuburinganire bwa kabiri bishyirwa mubyerekezo ibyo aribyo byose, ntabwo bihuye numurongo wambere, bikaba imbogamizi muguhuza insinga za Ultrasonic . Kubikorwa byikora, byinshi cyane, imipira yihuta cyane kurenza Ultrasonic / Thermosonic (Wedge), bigatuma umupira wa Thermosonic uhuza tekinoroji yiganjemo ikorana buhanga muri microelectronics mumyaka 50+ ishize.
Guhuza umugozi, ukoresheje kaseti ya metero nini, byiganje muri electronics ya RF na Microwave mumyaka mirongo (lente itanga iterambere ryinshi mugutakaza ibimenyetso [ingaruka zuruhu] hamwe ninsinga gakondo). Utubuto duto twa Zahabu, mubusanzwe bugera kuri 75µm z'ubugari na 25µm z'ubugari, duhujwe hakoreshejwe inzira ya Thermosonic hamwe nigikoresho kinini cyo guhuza imigozi ya wedge.Imyenda ya Aluminium igera kuri 2000µm z'ubugari na 250µm z'ubugari nazo zishobora guhuzwa n'inzira ya Ultrasonic, nkuko ibisabwa kumurongo wo hasi, ubucucike buri hejuru bwiyongereye.

Umugozi uhuza zahabu ni iki?

Guhuza insinga za zahabu nuburyo inzira ya zahabu ihujwe ningingo ebyiri mugiterane kugirango habeho guhuza cyangwa inzira ikoresha amashanyarazi. Ubushyuhe, ultrasonics, nimbaraga zose zikoreshwa mugukora ingingo zomugozi wumugozi wa zahabu. Igikorwa cyo gukora point de attachment gitangirana no gushiraho umupira wa zahabu kumutwe wigikoresho cyinsinga, capillary. Uyu mupira ukanda hejuru yubushuhe bushyushye mugihe ushyizemo imbaraga zidasanzwe zikoreshwa hamwe ninshuro ya 60kHz - 152kHz ya ultrasonic moteri hamwe nigikoresho.Imigozi ya mbere imaze gukorwa, insinga izakoreshwa muburyo bugenzurwa cyane uburyo bwo gukora imiterere ikwiranye na geometrie yinteko. Inkunga ya kabiri, bakunze kwita ubudozi, noneho ikorwa kurundi ruhande ukanda hasi hanyuma ugakoresha clamp kugirango ushishimure umugozi.

Guhuza insinga za zahabu bitanga uburyo bwo guhuza mubipaki bitwara amashanyarazi cyane, hafi yubunini burenze kubagurisha bamwe. Byongeye kandi, insinga za zahabu zifite kwihanganira okiside nyinshi ugereranije nibindi bikoresho byinsinga kandi byoroshye kurusha ibyinshi, ni ngombwa kubutaka bworoshye.
Inzira irashobora kandi gutandukana ukurikije ibikenewe n'inteko. Hamwe nibikoresho byoroshye, umupira wa zahabu urashobora gushyirwa kumwanya wa kabiri uhuza kugirango habeho umurunga ukomeye ndetse n '“yoroshye” kugirango wirinde kwangirika hejuru yikintu. Hamwe n'umwanya ufunganye, umupira umwe urashobora gukoreshwa nk'intangiriro yo guhuza imigozi ibiri, ugakora umurongo wa “V”. Iyo umugozi winsinga ugomba kurushaho gukomera, umupira urashobora gushyirwa hejuru yubudozi kugirango ube umurongo wumutekano, byongera ituze nimbaraga zinsinga. Porogaramu nyinshi zitandukanye nuburyo butandukanye bwo guhuza insinga ntizigira umupaka kandi birashobora kugerwaho hifashishijwe porogaramu ikora kuri sisitemu yo guhuza insinga za Palomar.
