Intshayelelo kumsebenzi weeNgqungquthela zeMetal kwiiBhloko zeTerminal
Imisebenzi yeengubo ingahlulwahlulwa ibe ziindidi ezintathu: imisebenzi yokukhusela, imisebenzi yombane, kunye nemisebenzi yoomatshini/yenkqubo.
1. Umsebenzi wokukhusela (ukumelana nokugqwala kunye nokuqina)
Lo ngumsebenzi osisiseko nobaluleke kakhulu wokugquma.
- Ukuthintela i-substrate oxidation kunye nokugqwala: I-Copper ingenza i-copper oxide okanye i-copper sulfide xa ivezwe emoyeni ofumileyo okanye kwiindawo ezine-sulfur. Ezi compounds azinawo amandla okuqhuba kakuhle kwaye zinokwenza umaleko wokukhusela, nto leyo ekhokelela ekwandeni ngequbuliso kokumelana nokuchukumisa, okunokubangela ukufudumala okanye ukungasebenzi kakuhle kwesekethe. I-coating isebenza "njengesithintelo" esixineneyo, esahlula i-substrate kwindawo engaphandle.
- Ukuphucula ukulungelelana nokusingqongileyo: Kwiimeko ezahlukeneyo zokusetyenziswa (ezifana nobushushu obuphezulu kunye nokufuma, i-salt spray, kunye neegesi zeekhemikhali zoshishino), ukukhetha i-coating efanelekileyo kunokuphucula kakhulu ukumelana nokugqwala kwee-terminals. Umzekelo, i-nickel okanye i-chromium plating isebenza kakuhle kakhulu kwiindawo zoshishino ezinzima.
2. Umsebenzi wombane (ukuqinisekisa ukusebenza kombane)
- Ukuzinzisa nokunciphisa ukumelana nokudibana: Ukubonelela ngomphezulu ongenakuxhathisa kakhulu: izinto ezifana netin nesilivere zinomoya oqhuba kakuhle kwaye azinawo umoya ongcolileyo, nto leyo enika indlela ezinzileyo nengenakuxhathisa kakhulu ukuhamba kombane.
- Iifilimu ze-oxide eziqhekezayo ezikhuselayo: Iingubo ezininzi (ingakumbi i-tin kunye ne-tin alloys) zithambile. Xa ii-terminals zikrwelwe okanye izikrufu ziqinisiwe, ingubo inokuguqulwa nge-microscopic kunye nokuhamba, ibhoboze ucingo okanye ifilimu ye-oxide kumphezulu we-terminal yokudibana, ivumela ukunxibelelana ngqo kwentsimbi kunye nesinyithi (oko kukuthi, "ukudibana kwesinyithi"), okunciphisa kakhulu ukumelana nokudibana.
- Ukugcina uzinzo lombane ixesha elide: Iingubo ezisemgangathweni ophezulu zinokugcina imeko yazo yomphezulu ngokuhamba kwexesha, zithintele ukuxhathisa okubangelwa kukugqwala kwaye ziqinisekise uqhagamshelo lombane oluzinzileyo kulo lonke ixesha lobomi bemveliso.
Imisebenzi yoomatshini kunye nokucubungula
Ukuphucula ukuWeldability: Kwiiterminal ezifuna ukuwelda (ezifana neeterminal zePCB), ukuplata kubalulekile. Ukuplata kwe-alloy ye-tin kunye ne-tin-lead kune-solderability egqwesileyo, okuqinisekisa ukuba amalungu e-solder akhawuleza, aqinile, kwaye athembekile. Ukuplata kwe-copper ecocekileyo kuyawohloka kakhulu emva kokunyibilika komphezulu, kwaye ukuplata kubonelela ngomphezulu ohlala ixesha elide otyibilikayo.
Ukuphucula Ukumelana Nokuguguleka: Iiterminal zihlala zisebenza ngokufaka iplagi okanye ukukhupha iplagi okanye ukuqinisa izikrufu ngexesha lokusetyenziswa. Iingubo eziqinileyo ezifana ne-nickel okanye i-chrome plating zinokunyusa ngokufanelekileyo ubulukhuni bomphezulu, zinciphise ukuguguleka kokufakwa ngokuphindaphindiweyo, kwaye zandise ubomi benkonzo. Zikwathintela ukuvezwa kwezinto ezingaphantsi ezibolayo ngenxa yokuguguleka.
Nciphisa ukungqubana komphezulu woqhagamshelwano: Iiplating ezithile (ezifana netin) zineempawu zokuzithambisa ngokwazo, zenza ukuqina kwezikrufu kube lula, i-torque izinze ngakumbi, kwaye zinciphisa ukungqubana phakathi kweentsimbi.
