[Abstract] Pa nthawiyi, pofuna kuonetsetsa kusonkhana ndi kusakanikirana kwakukulu kwa ntchito zamagetsi zagalimoto, ndikukwaniritsa chitukuko cha zomangamanga zatsopano zamagetsi zamagetsi, mawonekedwe osankhidwa omwe amasankhidwa amakhala ndi kusakanikirana kwakukulu (osati kokha kufalitsa kwambiri magetsi amakono komanso apamwamba, komanso kufalitsa ma siginecha otsika komanso otsika kwambiri), sankhani magawo osiyanasiyana olumikizirana ndi ntchito zosiyanasiyana ndi maudindo osiyanasiyana kuti muwonetsetse kuti moyo wautumiki wa cholumikizira usakhale wotsika kuposa moyo wautumiki. zamagalimoto abwinobwino, mkati mwazololedwa zolakwika Kutumiza kokhazikika kwamagetsi ndi ma sign owongolera kuyenera kutsimikiziridwa;zolumikizira zimalumikizidwa kudzera m'ma terminals, ndipo ma terminals achimuna ndi achikazi amapangidwa ndi zitsulo zopangira zitsulo.Ubwino wa kugwirizana kwa terminal umakhudza mwachindunji kudalirika kwa ntchito zamagetsi zagalimoto.
1 Mawu Oyamba
Mawaya otengera mawaya omwe amatumizidwa pakadali pano muzolumikizira zama waya nthawi zambiri amadindidwa kuchokera kuzitsulo zamkuwa zapamwamba kwambiri.Mbali imodzi ya matheminali iyenera kumangirizidwa ku chipolopolo cha pulasitiki, ndipo gawo lina likhale lolumikizidwa ndi magetsi ku malo okwererako.Aloyi yamkuwa Ngakhale imakhala ndi makina abwino, magwiridwe ake amachitidwe amagetsi siwokwanira; Nthawi zambiri, zida zokhala ndi magetsi abwino zimakhala ndi zida zamakina, monga malata, golide, siliva, ndi zina zotero.Chifukwa chake, plating ndiyofunikira kwambiri kuti ma terminal apereke madulidwe ovomerezeka amagetsi ndi zida zamakina nthawi imodzi.
2 Mitundu ya Plating
Chifukwa cha ntchito zosiyanasiyana za ma terminals ndi malo osiyanasiyana ogwiritsira ntchito (kutentha kwambiri, kusinthasintha kwa kutentha, chinyezi, kugwedezeka, kugwedezeka, fumbi, ndi zina), malo osankhidwa omwe amasankhidwa amakhalanso osiyanasiyana, nthawi zambiri chifukwa cha kutentha kosalekeza, makulidwe a plating, mtengo, kuphatikizira Chigawo choyenera cha plating chokwerera ndikusankha malo okhala ndi zigawo zosiyanasiyana zomangira kuti akwaniritse kukhazikika kwa ntchito yamagetsi.
3 Kufananiza Zovala
3.1 Malo okhala ndi malata
Kuyika malata nthawi zambiri kumakhala kukhazikika kwa chilengedwe komanso kutsika mtengo, motero kumagwiritsidwa ntchito kwambiri, ndipo pali zigawo zambiri zomangira malata zomwe zimagwiritsidwa ntchito mosiyanasiyana, monga malata akuda, malata owala, ndi malata otentha.Poyerekeza ndi zokutira zina, kukana kuvala kumakhala koyipa, kuchepera kwa 10 kukweretsa, ndipo kukhudzana kumachepa ndi nthawi ndi kutentha, ndipo nthawi zambiri amagwiritsidwa ntchito m'malo ozungulira 125 ° C.Popanga ma terminals okhala ndi malata, mphamvu yolumikizana kwambiri ndi kusamuka pang'ono kuyenera kuganiziridwa kuti zitsimikizire kukhazikika kwa kukhudzana.
3.2 Silver Plated Terminals
Silver plating nthawi zambiri imakhala ndi ntchito yabwino yolumikizirana, imatha kugwiritsidwa ntchito mosalekeza pa 150 ° C, mtengo wake ndi wokwera mtengo kwambiri, ndikosavuta kuchita dzimbiri mumlengalenga pamaso pa sulfure ndi chlorine, molimba kuposa plating ya malata, ndipo resistivity yake ndi pang'ono. apamwamba kuposa kapena ofanana ndi tini, chotheka cha electromigration chotheka chimatsogolera mosavuta ku zoopsa zomwe zingachitike pa cholumikizira.
3.3 Malo opaka golide
Malo opaka golide amakhala ndi kukhudzana kwabwino komanso kukhazikika kwa chilengedwe, kutentha kosalekeza kumatha kupitilira 125 ℃, ndipo kumakhala ndi kukana kwamphamvu kwambiri.Golide wolimba ndi wolimba kuposa malata ndi siliva, ndipo ali ndi mphamvu yolimbana ndi mikangano, koma mtengo wake ndi wokwera, ndipo si malo onse omwe amafunikira plating ya golide.Mphamvu yolumikizana ikakhala yochepa ndipo plating wosanjikiza wavala, plating ya golide ingagwiritsidwe ntchito m'malo mwake.Pokwerera.
4 Kufunika kwa Terminal Plating Application
Sizingachepetse kudzimbirira kwa zinthu zotsalira, komanso kupititsa patsogolo mphamvu yoyikapo.
4.1 Chepetsani kukangana ndikuchepetsa mphamvu yolowetsa
Zinthu zazikulu zomwe zimakhudza kugundana kwapakati pakati pa ma terminals ndi izi: zakuthupi, zovuta zapamtunda, ndi chithandizo chapamwamba.Zinthu zomaliza zikakhazikika, kugundana kwapakati pakati pa ma terminals kumakhazikika, ndipo roughness yake imakhala yayikulu.Pamene pamwamba pa chotchingacho chagwiritsidwa ntchito ndi zokutira, zokutira, makulidwe a zokutira, ndi kumaliza kwa zokutira zimakhala ndi zotsatira zabwino pa coefficient ya mikangano.
4.2 Pewani ma oxidation ndi dzimbiri pambuyo poti plating yawonongeka
Mkati mwa nthawi 10 zogwira ntchito populagi ndi kutulutsa, ma terminals amalumikizana wina ndi mnzake kudzera muzosokoneza.Pakakhala kukakamiza kolumikizana, kusamuka kwachibale pakati pa ma terminals achimuna ndi akazi kumawononga plating pamwamba pa terminal kapena kukanda pang'ono panthawi yosuntha.Kutsata kumabweretsa makulidwe osagwirizana kapena kuwonekera kwa zokutira, zomwe zimapangitsa kusintha kwa makina, zokopa, kumamatira, kuvala zinyalala, kusamutsa zinthu, ndi zina zambiri, komanso kutulutsa kutentha. Nthawi zambiri zomangira ndi kutulutsa, zimawonekera kwambiri. zokanda pamwamba pa terminal.Pansi pa ntchito ya nthawi yayitali komanso chilengedwe chakunja, terminal ndi yosavuta kulephera.Zimakhala makamaka chifukwa cha dzimbiri zobwera chifukwa cha okosijeni kayendedwe ka waung'ono wachibale wa kukhudzana pamwamba, kawirikawiri 10 ~ 100μm wachibale kayendedwe;kusuntha kwachiwawa kungayambitse kuvala koyipa pakati pa malo olumikizana, kugwedezeka pang'ono kungayambitse dzimbiri, kugwedezeka kwamafuta ndi zikoka za chilengedwe zimafulumizitsa njirayi.
5 Mapeto
Kuwonjezera plating wosanjikiza ku terminal sikungangochepetse dzimbiri pamwamba pa zinthu zomaliza, komanso kuwongolera mphamvu yoyikapo.Komabe, kuti apititse patsogolo ntchito ndi chuma, plating wosanjikiza makamaka amatanthauza zinthu zotsatirazi: akhoza kupirira kutentha kwenikweni kutentha kwa terminal;kuteteza zachilengedwe , zosawononga;mankhwala okhazikika;kukhudzana kotsimikizika kwa terminal;kuchepetsa kukangana ndi kuvala kutchinjiriza;mtengo wotsika.Pamene chilengedwe chamagetsi cha galimoto yonse chikukhala chovuta kwambiri ndipo nthawi ya mphamvu yatsopano ikubwera, pokhapokha pofufuza nthawi zonse teknoloji yopangira zigawo ndi zigawo zikuluzikulu zomwe zingatheke kuwonjezereka kwachangu kwa ntchito zatsopano.
