Lub hauv paus ntsiab lus ntawm laser electroplating rau hluav taws xob cua sov raj
PCB kev tsim khoom yog tsim los ntawm ntau txheej txheej, txheej txheej, kev ua haujlwm, thiab kev sib koom ua ke. Nrog rau txoj kev loj hlob sai ntawm microelectronics technology, lub tswv yim thiab kev tsim ntawm cov duab kos duab tau raug txhawb kom siv ntau qhov me me, qhov nrug nqaim, thiab cov xov hlau zoo hauv kev tsim cov ntawv luam tawm. Qhov no ua rau PCB manufacturing technology nyuaj dua, tshwj xeeb tshaj yog thaum qhov piv ntawm cov qhov nyob rau hauv multi-layer boards tshaj 5: 1 thiab qhov tob qhov muag tsis pom qhov dav siv nyob rau hauv laminated boards ua pa ntsug electroplating txheej txheem tsis tau raws li cov kev cai ntawm high-zoo. thiab kev ntseeg siab ntawm kev sib tshuam qhov. Lub ntsiab yog vim li cas rau qhov no yuav tsum tau soj ntsuam los ntawm lub hauv paus ntsiab lus electroplating hais txog qhov tam sim no tis raws li txoj cai. Thaum lub sij hawm electroplating tiag tiag, nws tau pom tias qhov kev faib tawm tam sim no hauv lub qhov nthuav tawm lub duav nruas zoo li lub duav, ua rau qhov kev faib tawm tam sim no hauv lub qhov yuav maj mam txo los ntawm lub qhov ntug mus rau qhov chaw, uas ua rau muaj ntau ntawm tooj liab deposition ntawm qhov chaw. thiab qhov ntug. Nws tsis tuaj yeem ua kom ntseeg tau tias cov txheej tooj liab nyob hauv nruab nrab ntawm lub qhov uas xav tau tooj liab yuav tsum ncav cuag tus qauv tuab. Qee lub sij hawm, cov txheej tooj liab yog nyias nyias lossis tsis muaj txheej tooj liab, uas tuaj yeem ua rau tsis muaj kev puas tsuaj thaum muaj xwm txheej hnyav, Ua rau muaj ntau ntau cov txheej txheem ntau lawm. Txhawm rau daws cov teeb meem zoo hauv kev tsim khoom loj, tam sim no thiab cov kev daws teeb meem ntxiv yog tam sim no siv los daws qhov teeb meem ntawm qhov sib sib zog nqus electroplating. Nyob rau hauv lub siab nam piv PCB tooj liab electroplating txheej txheem, feem ntau ntawm lawv yog pab los ntawm high-zoo additives, ua ke nrog nruab nrab cua stirring thiab cathode txav, nyob rau hauv kuj tsis tshua muaj tam sim no ceev tej yam kev mob los mus nce lub electrode tshuaj tiv thaiv cheeb tsam nyob rau hauv lub qhov, thiab cov nyhuv. ntawm electroplating additives tuaj yeem pom. Tsis tas li ntawd, cathode txav tau zoo heev rau kev txhim kho qhov sib sib zog nqus plating muaj peev xwm ntawm cov txheej txheem plating thiab ua kom cov polarization ntawm plating daim, qhov tsim tus nqi ntawm cov siv lead ua nuclei thiab grain loj hlob tus nqi yog sib sib zog nqus compensated thaum lub sij hawm electrodeposition txheej txheem ntawm txheej, yog li tau txais. high toughness tooj liab txheej.
