1.2 Txheej Blossom

Qhov tshwm sim ntawm burrs ntawm lub workpiece thaum lub sij hawm electroplating yog ib qho txhaum. Muaj ntau yam uas tuaj yeem ua rau pob, thiab lawv yuav tsum tau kho qhov sib txawv.

(1) Substrate defects, corrosion marks, thiab txheej tsim nyob rau hauv cov cheeb tsam no yuav paj, thiab nyob rau hauv loj heev, lub txheej yuav tsis tsim. Qhov txhaum no tsis tuaj yeem daws tau los ntawm electroplating.

(2) Yog hais tias cov roj los yog xeb stains ntawm lub workpiece tsis raug tshem tawm tag nrho, cov txheej ntawm cov khoom no yuav paj, tev tawm, los yog ua tsis tiav rau txheej txheej. Ntev npaum li cov roj thiab xeb tshem tawm muaj zog, nws tuaj yeem zam tau.

(3) Tom qab cov kua qaub etching ntawm lub workpiece, yog tias nws tsis tau ntxuav kom huv si, nws yuav nkag mus rau hauv lub plating tank, thiab cov kua qaub seem yuav nyob twj ywm ntawm lub workpiece, ua rau nws tawg. Txhim kho kev tu kom huv tuaj yeem tshem tawm nws.

(4) Yog hais tias lub workpiece tsis ntxuav kom huv si tom qab plating, passivation kev kho mob yuav ua. Cov zaj duab xis passivation ntawm qhov seem ntawm cov tshuaj plating yog nquag mus rau tawg, thiab ntxiv dag zog ntxuav tuaj yeem tshem tawm.

(5) Cov additive yog undiluted thiab nkag mus rau hauv lub plating tov tsis muaj sij hawm txaus los yaj thiab diffuse, ua rau ib tug milky xim thiab ua rau lub txheej kom tawg. Cov tshuaj ntxiv yuav tsum tau diluted thiab tuaj yeem zam tau los ntawm kev ntxiv rau hauv lub tank nrog nplawm.

(6) Lub workpiece yog dai kom nruj heev, thiab txheej txheej ntawm qhov chaw uas nws npog ib leeg tsis muaj qhov ci, tsim lub paj zoo li tus qauv ntawm sab zoo thiab tsis zoo. Txo tus naj npawb ntawm workpieces tuaj yeem tiv thaiv kev ua haujlwm tsis zoo.

(7) Qhov kev ncua deb ntawm cov anode thiab anode tshaj 300mm, thiab cov kab hluav taws xob tau muab faib rau hauv qhov sib txawv ntawm ob lub anodes, ua rau cov paj dawb zoo li cov qauv ntawm sab zoo thiab tsis zoo. Yog tias qhov sib nrug ntawm qhov anode raug tswj ntawm 300 hli, qhov tshwm sim no yuav tsis tshwm sim.

(8) Kev sib cuag ntawm tus anode tooj liab nuv thiab tus ncej pas nrig yog qhov tsis zoo, thiab cov khoom siv hluav taws xob hauv zos ntawm cov khoom ua haujlwm yog qhov ua rau paj tsim. Txav mus rau lub anode los ua hluav taws xob thiab tshem tawm qhov yuam kev.

(9) Yog tias qhov ntev anode tsis txaus, lub workpiece tshaj qhov ntev ntawm anode, thiab cov kab hluav taws xob tsis tuaj yeem ncav cuag qhov ntau dhau, nws kuj yog qhov ua rau cov pos huab.
