I-conductive paste yesilivere ecocekileyoii powders zesilivere eziqhubayoyimathiriyeli yepolymer edibeneyo edibeneyo, eyintlama exutywe ngoomatshini eyenziwe ngomgubo wesilivere owenziwe ngesinyithi, isiseko seresin, isinyibilikisi kunye nezongezo.

I-slurry yesilivere ye-conductive ine-conductivity egqwesileyo yombane kunye nokusebenza okuzinzileyo.Yenye yezinto ezibalulekileyo ezisisiseko kwintsimi ye-elektroniki kunye ne-microelectronic technology.Isetyenziswa ngokubanzi kwisekethe edibeneyo ye-quartz yekristale ye-elektroniki, indibano yesekethe yefilimu engqingqwa, izixhobo kunye nezinye iinkalo.

I-conductive paste yesilivere yahlulwe yangamacandelo amabini:

I-1) I-polymer silver conductive paste (ebhakiweyo okanye ephiliswe ukwenza ifilimu, kunye ne-organic polymer njengesigaba sokudibanisa);

2) I-Sintered silver conductive paste (i-sintering ukwenza ifilimu, iqondo lobushushu le-sintering ngaphezulu kwe-500 ℃, umgubo weglasi okanye i-oxide njengenqanaba lokubopha)

Iindidi ezithathu zesilivere ye-conductive paste zifuna iintlobo ezahlukeneyo zeengqungquthela zesilivere okanye indibaniselwano njengezahlulo eziqhubayo, kunye neendlela ezahlukeneyo zokwakheka kwinqanaba ngalinye zifuna amaqhekeza e-Ag ahlukeneyo njengezinto ezisebenzayo ezisebenzayo.Injongo kukusebenzisa ubuncinane be-Ag powders phantsi kwefomula ethile okanye inkqubo yokwenza ifilimu ukuze kuphunyezwe ukusetyenziswa okuphezulu kombane kunye ne-thermal conductivity ye-Ag, enxulumene nokuphucula ukusebenza kwefilimu kunye neendleko.

I-conductivity ye-polymer igxininiswe ngokukodwa yi-conductive filler powder yesilivere, kwaye inani layo liyiyo yokugqiba ukusebenza kwe-conductive paste yesilivere.Impembelelo yomxholo we-powder yesilivere kwi-volume resistivity ye-conductive paste yesilivere inokunikwa kwiimvavanyo ezininzi, isiphelo kukuba umxholo we-particle yesilivere yeyona nto ingcono kakhulu kwi-70% ukuya kwi-80%.Iziphumo zovavanyo zihambelana nomthetho.Oku kungenxa yokuba xa umxholo we-powder yesilivere uncinci, amathuba okuba amaqhekeza adibanisane amancinci amancinci, kwaye i-network conductive ayilula ukwenza;xa umxholo umkhulu kakhulu, nangona amathuba oqhagamshelwano lwamasuntswana aphezulu, umxholo we-resin uncinci, kwaye i-resin edibanisa amaqhekeza esilivere inamathele, okwenza umphumo wokudibanisa uncitshiswe ngokuhambelanayo, ukuze ithuba leengqungquthela zidibanisane. kuncitshisiwe, kwaye uthungelwano lokuqhuba nalo luhlwempuzekile.Xa umxholo wokuzalisa ufikelela kwisixa esifanelekileyo, i-conductivity yenethiwekhi ingcono ukuba ibe neyona nto incinci yokuxhathisa kunye neyona nto inkulu. 

Ifomyula enye yereferensi yesilivere eqhubayo:

Ifomula 1:

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

Umgubo wesilivere: 70% -80%

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

I-Epoxy resin: i-arhente yokunyanga yi-1.0: (0.2~0.3)

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

Izinyibilikisi eziphezulu zokubilisa: ibutyl anhydride acetate, diethylene glycol butyl ether acetate, diethylene glycol ethyl ether acetate, isophorone

Esona sicelo siphambili sobushushu obuphantsi kunye nesiqhelo sokunyanga iglue yesilivere: ineempawu zobushushu obuphantsi bokunyanga, amandla okubopha okuphezulu, ukusebenza kombane okuzinzileyo, kwaye ilungele ukuprintwa kwesikrini, ukuhlangana kombane kunye ne-thermal conductivity kwizihlandlo zesiqhelo zokunyanga ubushushu, njenge. iikristale zequartz, i-infrared pyroelectric detectors, i-piezoelectric ceramics, i-potentiometers, iityhubhu ezikhanyayo kunye nokukhusela, ukulungiswa kweesekethe, njl.

Ukukhethwa kwe-agent ephilisayo kuhambelana nobushushu bokunyanga kwe-epoxy resin.Iipolyamines kunye ne-polythiamines zisetyenziselwa ukunyanga kumaqondo obushushu aqhelekileyo, ngelixa i-acid anhydrides kunye ne-polyacids zisetyenziswa ngokubanzi njengeejenti zokunyanga ukunyanga kumaqondo obushushu aphezulu.Iiarhente ezahlukeneyo zokunyanga zineempendulo ezahlukeneyo zokuhlangana.

Umthamo we-ejenti yokunyanga: ukuba inani le-ejenti yokunyanga lincinci, ixesha lokunyanga liya kwandiswa kakhulu okanye kube nzima ukunyanga;ukuba i-arhente yokuphilisa kakhulu, iya kuchaphazela ukuqhutyelwa kwe-paste yesilivere kwaye ayihambisani nokusebenza.

Kwinkqubo ye-epoxy kunye ne-ejenti yokunyanga, indlela yokukhetha i-diluent efanelekileyo inxulumene nombono womyili wefomula, njengokuqwalasela: ixabiso, isiphumo sokuhlanjululwa, ivumba, ubulukhuni benkqubo, ukuxhathisa ubushushu benkqubo, njl.

I-dosage ye-diluent: ukuba i-dosage ye-diluent incinci kakhulu, isantya sokunyibilika se-resin siya kucotha kwaye intlama iya kuba ne-viscous kakhulu;ukuba idosi ye-diluent inkulu kakhulu, ayihambisani nokuguquguquka kwayo kunye nokunyangwa.
