Ku antswisa ku namarhela exikarhi ka rhaba leyi nga ni vulcanized ni nsimbi i sayense leyi hambaneke, naswona minkarhi yin’wana swa tika ku fikelela ku namarhela lokunene. Hambi loko matirhelo yosungula ya bonding minkarhi yin’wana yari kahle, bonding, corrosion resistance xikan’we naku lwisana na ku dyuhala ka ndzhongho swinga va swiri kahle endzhaku ka ku dyuhala. Matirhelo yosungula ya bonding ahi xikombiso xa ntiyiso xa matirhelo ya bonding endzhaku ka ku dyuhala. Ku engetela kwalano, swikambelo swa standard bonding eka laboratory aswi kombisi hiku hetiseka ku hlanganisiwa ka xiviri ka rhaba na nsimbi ya switirhisiwa swa rhaba eka vuhumelerisi.

Xihlanganisi lexi tolovelekeke xa rhaba-ku-ya-eka-metal i bond ya rhaba-ku-ya-eka-wire, leyi eka xiyimo lexi entiyisweni ku nga waya lowu pfanganisiweke na koporo, naswona swin’wana leswi hlanganisiweke swa rhaba-ku-ya-eka-metal swi hlamuseriwile laha hansi. Swikimi kumbe miehleketo ya swikambelo leswi landzelaka swi nga antswisa ku hlangana exikarhi ka rhaba na nsimbi.

1. NR .

Hi ntolovelo rhaba ya ntumbuluko yi boha ku antswa eka waya wa nsimbi lowu pfanganisiweke ni koporo.

2. Minyu ya cobalt .

Ti salts ta cobalt titala ku cheriwa eka ti formulations ta rhaba kuva ti antswisa ku namarhela ka rhaba kuya eka brass-plated steel wire. Ti cobalt salts ti khumba vuhumelerisi bya copper sulfide ehenhla ka wire, leswi pfunetaka ku 'anchor' rhaba kuya eka waya, naswona ti antswisa ku namarhela kosungula na ku dyuhala ka rhaba kuya eka waya lowu pfanganisiweke na brass. Ku engetela nhlayo ya munyu wa cobalt swihunguta swivumbeko swa ku dyuhala ka ndzhongho naswona swi hatlisisa sulphur vulcanization. Entiyisweni, ku engetela nhlayo ya munyu wa cobalt swi antswisa ku hlangana ko sungula kambe swi hunguta ku hlangana endzhaku ka ku dyuhala ka ndzhongho. Hikokwalaho, leswaku kuta ringanisiwa swivumbeko swohambana hambana, swa laveka ku hlawula nhlayo leyi faneleke ya munyu wa cobalt, sulphur na accelerator.

3. Resorcinol formaldehyde resin na melamine ya hexamethoxy .

Hi ntolovelo resorcinol formaldehyde resin na hexamethoxy melamine switirhisiwa na munyu wa cobalt ku antswisa ku bohana kosungula na ku boha ku boha, hikuva HMMM na RF swita crosslink in situ hi nkarhi wa maendlelo ya vulcanization ku sirhelela sisiteme eka ku khuluka ka ndzhongho.

4. Sulphur ya le henhla na ku tlakusa ka le hansi .

Eka ku namarhela kahle ka rhaba kuya eka waya wa nsimbi leyi pfanganisiweke na copper, nhlayo ya sulphur leyinga khulukiki eka sisiteme ya vulcanization yifanele kuva e henhla kasi nhlayo ya accelerator yifanele kuva yiri ehansi swinene, tani hileswi leswi switiyisisaka levele yale henhla ya CUXS formation ehenhla ka wire.

5. DCBS .

Eka rhaba ya bonding system, DCBS i accelerator leyi tirhisiwaka ngopfu, yinga hunguta rivilo ra vulcanization ku antswa kutlula ti sub-sulfur amide accelerators tin’wana, naswona xisweswo yi pfuneta ku antswisa matirhelo ya bonding. Ku engetela ratio ya sulphur / DCBS dosage, swinga antswisa matirhelo ya bonding yosungula xikan’we na matirhelo ya bonding ya ku dyuhala ya ndzhongho.

6. Silica .

Eka wire bonding compound, white carbon black yitala kutirhisiwa ku siva xiphemu xa carbon black, hikuva white carbon black yinga hlohletela ku tumbuluxiwa ka ZnO eka interface, hindlela yaleyo swi antswisa swivumbeko swosungula swa bonding xikan’we na swivumbeko swa bonding endzhaku ka ku dyuhala.

7. Khaboni ya ntima N326 .

Eka nsimbi ya wire bonding adhesive, N326 yitala ku hlawuriwa carbon black, hikuva carbon black leyi yinga nyika adhesive matimba ya kahle swinene ya rihlaza, hambi kuri eka mpimo wale hansi wa ha kota ku va na ku tiyisisiwa lokunene, naswona swa olova ku nghena eka waya ku tlakusa mbuyelo wa bonding.

8. Vuyelo bya stearic acid na zinc oxide .

Eka bonding adhesive material, stearic acid yotala swinene yita hunguta adhesive material endzhaku ka ndzhongho bonding, ngopfu ngopfu eka nhlayo yale henhla ya naphthenic cobalt. Stearic acid yotala swinene yingava na corrosive eka brass naswona hikokwalaho yina mbuyelo wo biha eka wire bonding. Hi ntolovelo zinc oxide film leyi vumbiwaka eka vuandlalo bya brass yi n’okisiwa hi stearic acid. Ku papalata leswi, stearic acid yifanele ku dyiwa hiku hatlisa eka vulcanization naswona zinc oxide leyi hlawuriweke yifanele kuva yiri na reactive yale henhla leswaku yita kota ku endla reaction hiku hatlisa na stearic acid. Ku engetela kwalano, zinc oxide/stearic acid ratio yifanele kuva yiri e henhla.

9. Vuyelo bya swiyimo swa vulcanization .

Endzhaku ko engetela mahiselo ya vulcanization kusuka eka 130°C kuya eka 190°C, matimba yo humesa ya rhaba/wire ya hunguteka hi linear.

10. peroxide vulcanization na xipfuno xo hlanganisa .

Ku tirhisiwa ka ti co-crosslinkers swita antswisa swivumbeko swa bonding swa peroxide vulcanized rubbers. Eka swiyimo swin’wana, ku engetela nhlayo ya zinc methacrylate (Saret 633), xipfuno xo hlanganisa, swi antswisa swivumbeko swa ku boha ka tintambhu ta nsimbi hi aluminiyamu, zinc kumbe plating ya koporo ehenhla ka rhaba.

.

12. Vutshunguri bya le henhla bya nsimbi .

Leswaku ku kumiwa swivumbeko swo antswa swa rhaba na nsimbi swo boha, vuandlalo bya nsimbi byi fanele ku hlayisiwa byi basile naswona byi tshunguriwa kahle loko byi nga si tirhisiwa.
