Ukuthuthukisa ukunamathela phakathi kwenjoloba evundleleni nensimbi kuyisayensi ehlukile, futhi kwesinye isikhathi kunzima ukufeza akessesion. Noma ngabe ukusebenza kwamabhondi okuqala kwesinye isikhathi kulungile, ukumelana nokugqwala kanye nokumelana nokumelana nokuqina komswakama kungenzeka kube mpofu ngemuva kokuguga. Ukusebenza kwe-Bonding kokuqala akusona isibikezeli esinembile sokusebenza kwe-Bonding ngemuva kokuguga. Ngaphezu kwalokho, izivivinyo ezijwayelekile zokuhlola elabhoratri azibonisi ngokuphelele ukubumbana kwangempela kwensimbi yemikhiqizo yenjoloba ekukhiqizeni.

Isibopho esivame kakhulu senjoloba iron-to-to-wire bond, kuleli cala empeleni empeleni yi-wire-plated wire, kanti ezinye izibopho zenjoloba zichazwe ngezansi. Lezi zinhlelo zokuhlola ezilandelayo noma imibono yokuhlola ingahle ithuthukise ubuhlobo phakathi kwenjoloba nensimbi.

1. NR

Imvamisa izibopho zenjoloba zemvelo zingcono kakhulu ku-wire yensimbi ekhonkolo.

2. Usawoti we-cobalt

Usawoti we-cobalt uvame ukwengezwa ekwakhiweni kwenjoloba ukuthuthukisa ukunamathela kwenjoloba kuya ku-wire wire. Ama-cobalt asawoti athinta ukukhiqizwa kwe-sulfide yethusi endaweni yokungena ngentambo, okusiza ukugcwala irabha kuya ocingweni, futhi athuthukise ukunamathela kokuqala nokuguga kwerabha ku-wire zethusi. Ukukhuphula inani lama-cobalt asawoti kunciphisa izakhiwo zokuguga futhi kusheshise i-sulfur Vulcanization. Eqinisweni, ukwandisa inani lama-cobalt asawoti kuthuthukisa ukubopha izibopho kokuqala kepha kunciphisa ukubopha imali ngemuva kokuguga komswakama. Ngakho-ke, ukuze ulinganise izakhiwo ezahlukahlukene, kuyadingeka ukukhetha inani elifanele likasawoti we-coballk, isibabule kanye ne-accelerator.

3. I-resorcinol formaldehyde resin ne-hexamethoxy melamine

Imvamisa i-resorcinol formaldehyde resin ne-hexamethoxy isetshenziswa ngosawoti we-coballk ukuthuthukisa ubuhlobo bokuqala kanye nokugunda okugulayo, ngoba i-hmmm ne-RF izokweqa eStu ngesikhathi senqubo yokuguguleka komswakama.

4. Isibabule esiphakeme kanye nokuphromotha okuphansi

Ukunamathela okuhle kwenjoloba kuya ku-wire yensimbi ekhokhwayo, okuqukethwe kwe-sulfur kwe-incoluble sohlelo lokuvuselela kufanele kube phezulu ngenkathi okuqukethwe ama-accelerator kufanele kube okuphansi, ngoba lokhu kuqinisekisa izinga eliphakeme lokwakheka kwe-CUX endaweni yocingo.

5. I-DCBS

Ku-Bonding System Rubber, i-DCBS iyisivinini esivame ukusetshenziswa, kunganciphisa ijubane le-vulcanization kangcono kunamanye ama-accelerator ashubile, futhi ngenxa yalokho asiza ukuthuthukisa ukusebenza kwe-bonding. Khulisa isilinganiso sama-sulfur / DCBs dosage, ungathuthukisa ukusebenza kokuqala kokubopha kanye nokusebenza kokuguga komswakama.

6. Silica

Engxenyeni yokubopha nge-wire bonding, i-carbon emhlophe emhlophe ivame ukusetshenziselwa ukufaka ingxenye yengxenye yekhabhoni emnyama, ngoba i-White Carbon Black ingakhuthaza isizukulwane se-ZNO esibonakalayo, ngaleyo ndlela sithuthukise izakhiwo zokubopha izibopho zokuqala kanye nezakhiwo ezibophayo ngemuva kokuguga.

7. I-Carbon Black N326

Ku-adhesive yensimbi yensimbi yokuhlobisa, i-N326 ihlala ikhethwe i-carbon emnyama, ngoba le carbon emnyama inganikeza amandla amahle aluhlaza kakhulu, ngisho nomthamo ophansi usengaba nokuqiniswa okuhle, futhi kulula ukungena ocingweni ukuze kuthuthukiswe umphumela ophoqelelayo.

8. Stearic acid kanye ne-zinc onide umphumela

Ezintweni ezinamathela ngebhondi, kakhulu i-stearic acid izonciphisa impahla yokunamathela ngemuva kokubopha ukuguga kokuguga, ikakhulukazi esimweni samanani aphezulu we-naphthenic cobalt. I-Stearic acid eningi kakhulu ingaba namandla ethusi ngakho-ke yiba nomthelela omubi ekubumbeni ngocingo. Imvamisa ifilimu ye-zinc onide eyakhiwe ebusweni bethusi incibilike yi-acid eqinile. Ukugwema lokhu, i-Stearic acid kufanele idliwe ngokushesha eVulcan kanti uZinc onide okhethiwe kufanele asebenze kakhulu ukuze akwazi ukusabela ngokushesha nge-stearic acid. Ngaphezu kwalokho, isilinganiso se-zinc oxide / i-stearic acid isilinganiso kufanele sibe phezulu.

9. Umphumela Wezimo Ze-Vulcanization

Ngemuva kokukhulisa amazinga okushisa we-vulcanization kusuka ku-130 ° C kuya ku-190 ° C, amandla okukhishwa enjoloba / wire ancipha ngokuqondile.

10. I-Peroxide Vulcanization kanye nosizo lokuxhumanisa

Ukusetshenziswa kwama-croslinkers kuzothuthukisa izakhiwo ezibophayo ze-peroxide avukuvule. Kwezinye izimo, okwandisa inani le-zinc methacrylate (sart 633), usizo lokuwela, kuthuthukisa izindawo zokubopha izintambo zezintambo zensimbi nge-aluminium, i-zinc noma i-brass sliating ebusweni kuya enjoloba.

11. Ku-neoprene kanye ne-wret wire wire bonding adhesive, ukunciphisa inani lesibabule, ngokuvamile izingxenye ezi-0,5 (isisindo), inani lesibabule ezibonakalayo ezinamathela emvelo ngokuvamile okungenani izingxenye ezi-3 (isisindo).

12. Ukwelashwa okungaphezulu kwensimbi

Ukuze uthole izakhiwo ezingcono zenjoloba kanye nensimbi, ingaphezulu lensimbi kufanele ligcinwe lihlanzekile futhi liphathwe kahle ngaphambi kokusebenzisa.
