Conductive adhesive inonamira yakakosha, inonyanya kuumbwa neresin uye conductive filler (senge sirivheri, goridhe, mhangura, nickel, tin uye alloys, kabhoni poda, graphite, nezvimwewo), inogona kushandiswa kusungirira mune microelectronic zvikamu uye kurongedza kugadzira. process zvinhu.

Kune akawanda marudzi e conductive adhesives.Zvinoenderana neakasiyana conductive particles, conductive adhesives inogona kukamurwa kuita simbi (goridhe, sirivheri, mhangura, aruminiyamu, zingi, simbi, nickel hupfu) -based uye kabhoni-based conductive adhesives.Pakati pezvinonamira zviri pamusoro apa, iyo conductive adhesive yakagadzirwa nesirivheri poda ine yakanakisa conductivity, inonamira uye kugadzikana kwekemikari, haizove yakashongedzwa muadhesive layer, uye iyo oxidation mwero mumhepo zvakare inononoka zvakanyanya kunyangwe iine oxidized. yakagadzirwa sirivheri oxide ichine yakanaka conductivity.Naizvozvo, mumusika, kunyanya mumidziyo yemagetsi ine yakakwirira kuvimbika zvinodiwa, conductive adhesives nesirivheri poda se conductive fillers ndiyo inonyanya kushandiswa.Mukusarudza kwematrix resin, epoxy resin yave sarudzo yekutanga nekuda kwehuwandu hwayo hwepamusoro hwemapoka anoshanda, kusimba kwakabatana kwepamusoro, kunamatira kwakanaka, yakanakisa michina zvivakwa, uye yakanakisa kusanganisa zvinhu.

Rinisirivha upfuinowedzerwa kune epoxy adhesive se conductive filler, yayo conductive mashandiro ndiko kusangana pakati pesirivheri poda.Pamberi pekunamatira conductive kupora uye kuomeswa, iyo sirivha yehupfu mu epoxy adhesive iripo yakazvimiririra uye haina kuratidza kuenderera mberi kune mumwe nemumwe, asi iri mune isiri-conductive uye insulating mamiriro.Mushure mekuporesa uye kuomeswa, semugumisiro wekuporeswa kwegadziriro, mashefu esirivha akabatanidzwa kune mumwe nemumwe mumaketani emaketani kuti aite network conductive, ichiratidza conductivity.Mushure mekuwedzera sirivha poda kune epoxy adhesive nekuita kwakanaka (huwandu hwekuomesera mumiririri uye mumiririri wekurapa ndeye 10% uye 7% ye epoxy resin mass, zvichiteerana), kuita kunoedzwa mushure mekurapa.Zvinoenderana nedhata yekuyedza, sezvo huwandu hwekuzadza kwesirivheri mune conductive adhesive inowedzera, vhoriyamu resistivity inoderera zvakanyanya.Izvi zvinodaro nekuti kana sirivheri yehupfu yemukati idiki kwazvo, huwandu hweresin muhurongwa hwakanyanya kupfuura iyo conductive filler sirivheri poda, uye iyo sirivheri poda yakaoma kubata kuti igadzire inoshanda conductive network, nekudaro inoratidza kupikisa kwepamusoro. .Nekuwedzera kweiyo sirivheri poda yekuzadza huwandu, kudzikira kweiyo resin kunowedzera kusangana kwesirivheri poda, iyo inobatsira pakugadzirwa kweiyo conductive network uye inoderedza vhoriyamu resistance.Kana huwandu hwekuzadza huri 80%, vhoriyamu resistivity iri 0.9 × 10-4Ω • cm, ine yakanaka conductivity, FYI.

Sirivha hupfuine inogadziriswa particle size (kubva 20nm-10um), akasiyana maumbirwo (spherical, padyo-spherical, flake) uye customized sevhisi density, SSA, nezvimwewo zviripo.

Kuti uwane rumwe ruzivo, ndapota usazeza kutibata.
