Nyob rau hauv kev tsim kho ntawm cov khoom siv hluav taws xob niaj hnub no, PCB luam tawm Circuit Board ua lub luag haujlwm tseem ceeb, thiab tus ntiv tes kub, yog qhov tseem ceeb ntawm kev sib txuas ntawm kev ntseeg siab, nws qhov zoo ntawm qhov chaw ncaj qha cuam tshuam rau kev ua haujlwm thiab kev pabcuam lub neej ntawm lub rooj tsavxwm.
Cov ntiv tes kub yog hais txog qhov kub kub ntawm lub npoo ntawm PCB, uas feem ntau yog siv los tsim kom muaj kev sib txuas hluav taws xob ruaj khov nrog lwm cov khoom siv hluav taws xob (xws li lub cim xeeb thiab motherboard, daim npav duab thiab tus tswv tsev interface, thiab lwm yam). Vim nws cov khoom siv hluav taws xob zoo heev, kev tiv thaiv corrosion thiab tsis tshua muaj kev sib cuag, kub yog dav siv nyob rau hauv xws li kev twb kev txuas qhov chaw uas yuav tsum tau nquag ntxig thiab tshem tawm thiab tswj lub sij hawm ntev stability.
Kub plating ntxhib nyhuv
Kev ua haujlwm tsis zoo ntawm hluav taws xob: Qhov ntxhib ntawm cov ntiv tes kub yuav ua rau muaj kev tiv thaiv kev sib cuag, ua rau muaj kev cuam tshuam ntau ntxiv hauv cov teeb liab kis tau tus mob, uas yuav ua rau cov ntaub ntawv tsis raug lossis kev sib txuas tsis ruaj khov.
Txo durability: Qhov ntxhib saum npoo yog yooj yim los sau cov plua plav thiab oxides, uas ua rau kom hnav cov txheej kub thiab txo qhov kev pab cuam lub neej ntawm cov ntiv tes kub.
Kev puas tsuaj rau cov khoom siv tsis zoo: Qhov chaw tsis sib xws tuaj yeem khawb qhov chaw sib cuag ntawm lwm tus neeg thaum lub sij hawm ntxig thiab tshem tawm, cuam tshuam qhov nruj ntawm kev sib txuas ntawm ob tog, thiab tej zaum yuav ua rau muaj kev cuam tshuam los yog tshem tawm.
Aesthetic poob: Txawm hais tias qhov no tsis yog qhov teeb meem ncaj qha ntawm kev ua tau zoo, cov tsos ntawm cov khoom kuj yog ib qho tseem ceeb ntawm qhov zoo, thiab kub plating ntxhib yuav cuam tshuam rau cov neeg siv khoom 'kev ntsuam xyuas tag nrho ntawm cov khoom.
Txaus siab rau qib zoo
Kub plating thickness: Feem ntau, kub plating thickness ntawm tus ntiv tes kub yuav tsum nyob nruab nrab ntawm 0.125μm thiab 5.0μm, tus nqi tshwj xeeb nyob ntawm daim ntawv thov kev xav tau thiab cov nqi txiav txim siab. Nyias heev yog yooj yim hnav, tuab heev yog kim heev.
Nto roughness: Ra (arithmetic txhais tau tias roughness) yog siv los ntsuas ntsuas, thiab cov qauv tau txais ntau yog Ra≤0.10μm. Cov qauv no ua kom muaj kev sib cuag hluav taws xob zoo thiab ua haujlwm ntev.
Txheej txheej uniformity: Cov txheej kub yuav tsum tau npog tsis sib xws yam tsis muaj qhov pom tseeb, raug tooj liab lossis npuas kom ntseeg tau tias qhov ua tau zoo ntawm txhua qhov chaw sib cuag.
Weld peev xwm thiab corrosion resistance test: ntsev tsuag tshuaj ntsuam, kub thiab high humidity xeem thiab lwm txoj kev los ntsuam xyuas cov corrosion kuj thiab ntev kev cia siab ntawm cov ntiv tes kub.
Cov kub-plated roughness ntawm kub ntiv tes PCB pawg thawj coj saib ncaj qha rau kev sib txuas kev ntseeg siab, kev pab lub neej thiab kev lag luam kev sib tw ntawm cov khoom siv hluav taws xob. Ua raws li cov qauv kev tsim khoom nruj thiab kev lees paub, thiab kev siv cov txheej txheem kub plating zoo yog qhov tseem ceeb los ua kom cov khoom ua tau zoo thiab cov neeg siv kev txaus siab.
Nrog rau kev nce qib ntawm cov thev naus laus zis, kev lag luam hluav taws xob tsim hluav taws xob tseem niaj hnub tshawb nrhiav ntau dua, tus phooj ywg zoo ib puag ncig thiab kev lag luam kub-plated hloov kom tau raws li cov kev xav tau siab dua ntawm cov khoom siv hluav taws xob yav tom ntej.
