Mukugadzirwa kwakanyatsogadzirwa kwezvigadzirwa zvemagetsi zvemazuva ano, PCB yakadhindwa yedunhu bhodhi inoita basa repakati, uye Gold Finger, sechikamu chinokosha chekubatana kwepamusoro-soro, hutano hwayo hwepamusoro hunobata zvakananga kushanda uye hupenyu hwebasa rebhodhi.
Chigunwe chegoridhe chinoreva bhara rekusangana negoridhe pamucheto wePCB, iro rinonyanya kushandiswa kumisikidza yakagadzikana yemagetsi kubatana nezvimwe zvinhu zvemagetsi (senge memory uye mamaboard, giraidhi kadhi uye host interface, nezvimwewo). Nekuda kwekunaka kwayo kwemagetsi conductivity, corrosion resistance uye kushomeka kwekubata kuramba, goridhe rinoshandiswa zvakanyanya munzvimbo dzakadai dzekubatanidza dzinoda kugara dzichiiswa nekubvisa uye kuchengetedza kugadzikana kwenguva refu.
Gold plating rough effect
Kudzikira kwekuita kwemagetsi: Iyo yakakasharara yemunwe wegoridhe ichawedzera kuramba kubata, zvichikonzera kuwedzera attenuation mukufambiswa kwechiratidzo, izvo zvinogona kukonzera kukanganisa kwekufambisa data kana kusagadzikana kubatana.
Yakaderedzwa kusimba: Iyo yakakasharara iri nyore kuunganidza huruva uye okisidhi, iyo inomhanyisa kupfeka kweiyo goridhe layer uye inoderedza hupenyu hwebasa remunwe wegoridhe.
Yakakuvadzwa michina zvivakwa: Iyo isina kuenzana nzvimbo inogona kukwenya nzvimbo yekubatana yerimwe bato panguva yekuiswa nekubvisa, zvichikanganisa kusimba kwekubatana pakati pemapato maviri, uye inogona kukonzera yakajairika kuiswa kana kubviswa.
Aesthetic inodzikira: kunyangwe iri risiri dambudziko rakananga rekuita kwehunyanzvi, kutaridzika kwechigadzirwa zvakare kwakakosha kuratidzwa kwemhando, uye hutsinye hwegoridhe huchakanganisa kuongororwa kwevatengi kwechigadzirwa.
Chiyero chinogamuchirwa chemhando
Ukobvu hwekuisa goridhe: Kazhinji, ukobvu hwegoridhe hwechigunwe chegoridhe hunodiwa kuve pakati pe0.125μm uye 5.0μm, kukosha chaiko kunoenderana nezvinodiwa zvekushandisa uye kufunga kwemitengo. Kuonda zvakanyanya kuri nyore kupfeka, kukora zvakanyanya kunodhura.
Kushata kwepamusoro: Ra (arithmetic zvinoreva roughness) inoshandiswa sechiyero chekuyera, uye inowanzogamuchira mwero iRa≤0.10μm. Iyi chiyero inovimbisa kubata kwakanaka kwemagetsi uye kusimba.
Coating kufanana: Iyo goridhe layer inofanirwa kuvharwa zvakaenzana pasina mavara ari pachena, kuratidzwa kwemhangura kana mabubble kuti ive nechokwadi chekuita kunoenderana kweimwe neimwe nzvimbo yekusangana.
Weld kugona uye corrosion kuramba bvunzo: munyu wekupfapfaidza bvunzo, tembiricha yakakwira uye yakakwira humidity bvunzo uye dzimwe nzira dzekuyedza kuramba kwekuora uye kuvimbika kwenguva refu kwechigunwe chegoridhe.
Iyo goridhe-yakaiswa roughness yeGoridhe chigunwe PCB board yakanangana nekuvimbika kwekubatanidza, hupenyu hwebasa uye kukwikwidza kwemusika wezvigadzirwa zvemagetsi. Kuomerera kune akasimba ekugadzira zviyero uye nhungamiro yekugamuchira, uye kushandiswa kwemhando yepamusoro yegoridhe maitiro akakosha pakuita kuti chigadzirwa chishande uye kugutsikana kwemushandisi.
Nekufambira mberi kwetekinoroji, indasitiri yekugadzira zvemagetsi iri kuramba ichiongorora dzimwe nzira dzakasimba, dzinochengetedza nharaunda uye dzehupfumi dzakaputirwa negoridhe kuti dzisangane nepamusoro zvinodiwa zvemagetsi emangwana.
