I-conductive silver paste ehlanzekileconductive silver powdersiyinhlanganisela ye-polymer ehambisa izinto, okuyingxube yemishini yokunamathisela eyakhiwe nge-metal conductive silver powder, i-base resin, i-solvent kanye nezithasiselo.

I-conductive silver slurry ine-conductivity kagesi enhle kakhulu nokusebenza okuzinzile.Ingenye yezinto ezibalulekile eziyisisekelo emkhakheni we-elekthronikhi kanye nobuchwepheshe be-microelectronic.Isetshenziswa kabanzi ezingxenyeni ze-elekthronikhi ze-quartz crystal ehlanganisiwe, umhlangano wesifunda sefilimu ewugqinsi, i-instrumentation neminye imikhakha.

I-conductive silver paste ihlukaniswe izigaba ezimbili:

1) I-polymer silver conductive paste (ebhakiwe noma yelashwe ukuze yakhe ifilimu, ene-organic polymer njengesigaba sokubopha);

2) Sintered silver conductive unama (sintering ukwakha ifilimu, sintering izinga lokushisa phezu 500 ℃, ingilazi powder noma oxide njengesigaba bonding)

Izigaba ezintathu zesiliva conductive paste zidinga izinhlobo ezahlukene zezinhlayiya zesiliva noma izinhlanganisela njengezigcwalisi ze-conductive, futhi ngisho nokwakheka okuhlukile esigabeni ngasinye kudinga izinhlayiya ze-Ag ezihlukile njengezinto ezisebenzayo ezisebenzayo.Injongo ukusebenzisa inani elincane le-Ag powders ngaphansi kwefomula ethile noma inqubo yokwenza ifilimu ukuze kufinyelelwe ukusetshenziswa okuphezulu kwe-Ag's conductivity kagesi kanye ne-thermal, okuhlobene nokuthuthukiswa kokusebenza kwefilimu nezindleko.

I-conductivity ye-polymer inqunywa ngokuyinhloko i-conductive filler silver powder, futhi inani layo liyisici esinqumayo sokusebenza kwe-conductive silver paste.Umthelela wokuqukethwe kwe-powder yesiliva kumthamo we-resistivity we-conductive silver paste unganikezwa ekuhlolweni okuningi, isiphetho siwukuthi okuqukethwe kwezinhlayiya zesiliva kungcono kakhulu ku-70% kuya ku-80%.Imiphumela yokuhlolwa ihambisana nomthetho.Lokhu kungenxa yokuthi lapho okuqukethwe kwe-powder yesiliva kukuncane, amathuba okuba izinhlayiya ezithintana nomunye zincane, futhi inethiwekhi ye-conductive akulula ukwakha;lapho okuqukethwe kukukhulu kakhulu, nakuba amathuba okuxhumana kwezinhlayiyana aphezulu, okuqukethwe kwe-resin kuncane kakhulu, futhi i-resin exhuma izinhlayiya zesiliva iyanamathela, okwenza umphumela wokuxhuma uncishiswe ngokufanayo, ukuze ithuba lezinhlayiya ezithintana zodwa. incishisiwe, futhi inethiwekhi ye-conductive nayo impofu.Lapho okuqukethwe kokugcwalisa kufinyelela inani elifanele, ukuqhutshwa kwenethiwekhi kungcono kakhulu ukuba ne-resistiveivity encane kakhulu kanye ne-conductivity enkulu kakhulu. 

Ifomula yereferensi yokuqala yokunamathisela okusiliva okuqhubayo:

Ifomula 1:

I-conductive silver paste reference formula 2: i-conductive silver powder, i-E-44 epoxy resin, i-tetrahydrofuran, i-polyethylene glycol

I-Silver powder: 70% -80%

I-Epoxy resin: i-tetrahydrofuran ingu-1: (2-3)

I-Epoxy resin: umenzeli olaphayo ngu-1.0: (0.2~0.3)

I-Epoxy resin: i-polyethylene glycol ingu-1.00: (0.05-0.10)

Izincibilikisi zamaphuzu aphezulu abilayo: i-butyl anhydride acetate, i-diethylene glycol butyl ether acetate, i-diethylene glycol ethyl ether acetate, isophorone

Ukusetshenziswa okuyinhloko kokushisa okuphansi nokujwayelekile okuphulukisa i-glue yesiliva ye-conductive: inezici zokushisa okuphansi kokuphulukisa, amandla okubopha okuphezulu, ukusebenza kukagesi okuzinzile, futhi ilungele ukuphrinta kwesikrini, ukubopha kagesi kanye ne-thermal conductivity ezikhathini zokushisa ezijwayelekile zokuphulukisa ukushisela, njenge amakristalu e-quartz, ama-infrared pyroelectric detectors, i-piezoelectric ceramics, potentiometers, amashubhu e-flash nokuvikela, ukulungiswa kwesekethe, njll. Angaphinde asetshenziselwe ukuxhumanisa i-conductive embonini ye-instrumentation yomsakazo, esikhundleni sokunamathisela kwe-solder ukuze kuzuzwe ukubopha okuqhutshwayo.

Ukukhethwa kwe-ejenti yokwelapha kuhlobene nezinga lokushisa lokuphulukisa le-epoxy resin.Ama-polyamines nama-polythiamines ngokuvamile asetshenziselwa ukwelapha emazingeni okushisa avamile, kuyilapho ama-acid anhydride nama-polyacids ngokuvamile asetshenziswa njengezinto zokwelapha ekwelapheni emazingeni okushisa aphezulu.Ama-ejenti okwelapha ahlukene anemiphumela ehlukene yokuxhumanisa.

Umthamo we-ejenti yokwelapha: uma inani le-ejenti yokwelapha lincane, isikhathi sokuphulukisa sizonwetshwa kakhulu noma kube nzima ukuselapha;uma i-ejenti yokwelapha kakhulu, izothinta ukuqhutshwa kwe-paste yesiliva futhi ayihambisani nokusebenza.

Kuhlelo lwe-epoxy kanye ne-ejenti elaphayo, indlela yokukhetha i-diluent efanelekile ihlobene nomqondo womklami wefomula, njengokucabangela: izindleko, umphumela wokuhlanjululwa, iphunga, ubulukhuni besistimu, ukumelana nezinga lokushisa kwesistimu, njll.

Umthamo we-Diluent: uma umthamo we-diluent uncane kakhulu, isivinini sokuqedwa se-resin sizohamba kancane futhi ukunamathisela kuzovame ukuba ne-viscous kakhulu;uma umthamo we-diluent mkhulu kakhulu, awuhambisani nokushintshashintsha kwawo kanye nokwelapha.
