Basic qauv ntawm kab rov tav electroplating system rau hluav taws xob cua sov raj
Cov txheej txheem ntawm kev tso cov PCB yog hloov los ntawm ntsug mus rau qhov sib npaug mus rau qib plating kua. Ntawm no, PCB yog cathode, raws li cov yam ntxwv ntawm kab rov tav electroplating. Qee qhov kab rov tav electroplating tshuab siv ob hom kev siv tam sim no: cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Los ntawm qhov kev xav ntawm kev khiav hauj lwm qhov yooj yim, nws yog ib qho kev siv cov khoom siv hluav taws xob. Lub conductive roller nyob rau hauv kab rov tav electroplating system tsis tsuas yog ua hauj lwm raws li ib tug cathode, tab sis kuj muaj lub luag hauj lwm ntawm conveying PCBs. Txhua lub tshuab hluav taws xob yog nruab nrog lub caij nplooj ntoos hlav, uas yog tsim los ua kom tau raws li qhov xav tau ntawm electroplating sib txawv thicknesses ntawm PCBs ({{0}}}10-500mm). Txawm li cas los xij, thaum lub sij hawm electroplating, txhua qhov chaw uas tuaj yeem cuam tshuam nrog cov tshuaj plating yuav raug coated nrog tooj liab, thiab lub kaw lus yuav tsis ua haujlwm ntev. Yog li ntawd, feem ntau ntawm cov kab rov tav electroplating tshuab tam sim no tsim tau tsim nrog cathodes uas tuaj yeem hloov mus rau anodes, thiab cov txheej txheem cathodes tuaj yeem siv los electrolyze thiab yaj cov tooj liab ntawm plated rollers. Rau kev tu lossis hloov lub hom phiaj, tus qauv electroplating tshiab kuj tseem siv rau hauv cov cheeb tsam uas nquag hnav thiab tsim kua muag kom yooj yim tshem tawm lossis hloov. Lub anode yog lub pob tawb titanium insoluble nrog ib qho kev hloov pauv loj, muab cais rau ntawm qhov chaw sab saud thiab qis ntawm PCB, muaj 25 hli txoj kab uas hla spherical soluble tooj liab nrog cov ntsiab lus phosphorus ntawm 0.004-0.006 feem pua. Qhov kev ncua deb ntawm cathode thiab anode yog 40mm.
Cov txheej txheem plating ntws nrawm nrawm rau hauv qhov chaw kaw plating da dej, alternating rov qab thiab tawm, nce thiab nqis. Cov dej ntws ntawm cov txheej txheem plating yog ua tiav los ntawm lub kaw lus uas muaj lub twj tso kua mis thiab lub nozzle. Thiab nws tuaj yeem ua kom qhov sib xws ntawm cov txheej txheem plating ntws. Cov tshuaj plating yog vertically txau mus rau PCB, tsim cov phab ntsa ntws tawm dav hlau vortex ntawm PCB nto. Lub hom phiaj kawg yog kom ua tiav cov dej ntws sai ntawm cov txheej txheem plating ntawm ob sab ntawm PCB thiab los ntawm qhov, tsim cov eddy tam sim no. Tsis tas li ntawd, lub tank tau nruab nrog lub tshuab pom, uas siv lub mesh ntawm 1.2 microns los lim tawm cov impurities uas tsim los ntawm cov txheej txheem electroplating, kom ntseeg tau tias kev huv thiab tsis muaj kuab paug plating.
