Lub xub ntiag ntawm kub nyob rau hauv Circuit Court Board tuaj yeem txiav txim siab los ntawm cov hauv qab no:
Kev soj ntsuam txuj ci
X-Tshav Fluorescence spectroscopy (XRF): Tsis txhob nrhiav kev puas tsuaj uas tuaj yeem txheeb xyuas qhov tuab thiab muaj pes tsawg leeg ntawm cov txheej kub.
Zog dispersive x-ray spectroscopy (Edx): Tsim nyog rau cov ntsiab lus kub ntawm cov kab lus thiab cov ntsiab lus sib cuag.
Inductively txuas hniav ntshav ntau lub zog hluav taws xob (ICP-ms): Muaj siab paub txog cov hlau Cheebtsam xws li nyiaj, platinum, thiab palladium.
Kub Muaj Cov Circuit Court Board Hom
Sinking Kub phaj: cov cam ncoo muaj kub, cov qauv siv lead ua kom tuab, thiab nws tsis yooj yim oxidized.
Kub Plated Phaj: Qhov saum npoo yog coated nrog nyuaj kub (au co alloy), uas muaj qhov muaj zog hnav tsis kam thiab siv tau nyob rau hauv cov ntiv tes sib ze zoo xws li kub ntiv tes.
Tsis yog kub-plated phaj: ua los ntawm high-purity kub lub caij, txawm hais tias tsis yog suav, nws tseem muaj nqi.
Raug Daim Ntawv Teev Lus
Txawb xov tooj Motherboard: txhua lub xov tooj muaj kwv yees li 0.4 kilograms kub (noj 1 tuj ntawm cov xov tooj siv piv txwv).
Khoos phib tawj Motherboard: Cov ntsiab lus kub kub, tshwj xeeb tshaj yog cov qauv kub siab.
Tus ntiv tes precision interface (xws li kub ntiv tes): tau txais cov kub kub ultrasonic, lub hardness mus txog 200hv, thiab cov hnav tsis kam ntawm 5 zaug.
Kuaj cov kev ceev faj
Nws yog ib qho tsim nyog kom paub qhov txawv ntawm "nyuaj kub" (alloy) thiab "Kub Kub" (nrog cov qub kub), nrog cov qub kub thiab tau siv ntau dua hauv cov kev tshwm sim-resistant scenuctarios.
Cov txheej txheem kho deg ntawm cov Circuit Court (xws li Tin txau, plating, thiab cov nyiaj tso quav kub) tuaj yeem cuam tshuam rau cov txiaj ntsig nrhiav tau. Nws yog
Pom zoo los tshuaj xyuas nws raws cov txheej txheem tshwj xeeb.
1, tus qauv muag rau kev txheeb xyuas seb lub tshav ci hluav taws xob yog kub-plated
Firstly, peb tuaj yeem txiav txim siab ua haujlwm txiav txim siab seb lub Circuit Court Board yog kub-plated los ntawm kev saib nws cov xim. Feem ntau, saum npoo ntawm cov nyiaj kub-plated Circuit Court yuav tshwm nyiaj daj, thaum tsis pom nyiaj Circuit Court kuj tshwm sim nyiaj dawb, lossis lwm yam xim. Txawm li cas los xij, nws yuav tsum tau sau tseg tias cov xim tsis yog qhov kev txiav txim siab meej, raws li qee lub tsho muaj yees, ua rau tsis paub meej.
Thib ob, koj tuaj yeem hnov nws cov qauv los ntawm kov cov Circuit Court Board. Kub Plated Circuit Cots feem ntau muaj cov qauv zoo dua thiab ntau dua cov cim tseem ceeb tshaj li cov laug cam tsis tau pom. Ntawm chav kawm, cov qauv no xav tau qee qhov kev paub thiab sib piv los ua kom raug txiav txim siab.
2, siv tshuaj lom neeg cov tshuaj lom zem yog txiav txim siab yog tias Circuit Court Board yog kub-plated
Ntxiv rau cov hau kev tsis sib haum, tshuaj lom neeg kuj tseem siv tau los ua kev txiav txim. Piv txwv li, qee tee ntawm acid etching tus neeg sawv cev tuaj yeem raug hluav taws xob rau ntawm lub tooj liab txheej yog qhov nyuaj rau kev ua kom ncaj ncees los ntawm etching tus neeg sawv cev. Yog tias lub tooj liab txheej yog qhov nyuaj rau corrode, nws yog qhov yuav yog tias Circuit Court Board yog cov nyiaj kub-plated. Txawm li cas los xij, thov nco ntsoov tias siv tshuaj lom neeg yuav tsum ceev faj kom tsis txhob muaj kev puas tsuaj rau Circuit Courruit Board.
3, txiav txim siab seb lub Circuit Courch Board yog kub-plated los ntawm cov cuab yeej kuaj
Cov cuab yeej xws li multimeters lossis clamp gauges kuj tseem siv tau rau kev kuaj. Yog tias cov xov hlau hlau ntawm cov hlau Circuit Court kev ua tau zoo ua haujlwm zoo, tom qab ntawd Circuit Court Board yog qhov yuav ua rau kub-plated. Cov qauv no yog qhov raug yog, tab sis yuav tsum muaj qee yam kev paub txog kev ua haujlwm thiab kev ua haujlwm.
4, paub qhov txawv rau cov phiaj xwm plating kub ntawm Circuit Court
Cov txheej txheem ua plating kub rau cov pob zeb circuit Court tsuas yog suav nrog cov electroplating thiab immersion. Cov kub hluav taws xob feem ntau yog ua ua ntej ua cov npog ntsej muag, txheej txheej plating ib txheej ntawm npib tsib xee, nrog cov txheej hlau, nrog cov txheej hlau los tooj liab kub; Thiab cov nyiaj tso tawm kub yog nqa tawm tom qab ua cov npog ntsej muag, los ntawm cov tshuaj tiv thaiv kab tshuaj rau cov kub ua rau cov hlua khi, thiab cov hlau txheej yog tooj liab kub. Muaj qee yam sib txawv ntawm ob qho ntawm cov txheej txheem, qauv, thiab kev ua tau zoo. Yog li ntawd, thaum txawv txawm tias cov Circuit Courcuit Courner yog kub-Plated, kev txiav txim siab tuaj yeem ua los ntawm kev sib txuas ntawm cov txheej txheem saum toj no.
5, Cov Circuit Court board part nrog cov ntsiab lus kub tshaj plaws
Nyob rau hauv Circuit Court laug cam, cov seem nrog cov ntsiab lus kub siab yog feem ntau muaj kev cuam tshuam hauv kev cuam tshuam, slots, thiab cov thom khwm. Cov chaw no feem ntau yog them nrog qee cov micrs tuab txheej ntawm kub kom txhim kho conduction thiab corrosion tsis kam. Feem ntau cov ntiv tes xoo ntiv tes, uas yog hais txog cov neeg hlau txuas nrog rau cov motherboard modules lossis daim npav cim npe, yog feem ntau yog cov khoom siv kub kom ntseeg tau tias tsis yog oxidized.
