1. PCB los ntawm lub qhov plating
Muaj ntau txoj hauv kev los tsim ib txheej ntawm plating uas ua tau raws li qhov yuav tsum tau ua ntawm lub qhov phab ntsa ntawm lub substrate. Qhov no yog hu ua lub qhov phab ntsa ua kom ua haujlwm hauv cov ntawv thov kev lag luam. Nws cov PCB board manufacturers siv ntau qhov nruab nrab cia tso tsheb hlau luam hauv cov txheej txheem ntau lawm. Txhua lub tank cia Lub tank muaj nws tus kheej tswj thiab tu cov cai. Los ntawm-qhov electroplating yog cov txheej txheem tsim nyog tsim nyog ntawm cov txheej txheem drilling. Thaum lub laum me ntsis xyaum los ntawm cov ntawv ci tooj liab thiab cov substrate hauv qab no, lub tshav kub generated melts lub insulating hluavtaws resin uas tsim lub hauv paus ntawm feem ntau substrates, cov molten resin thiab lwm yam drilling fragments Nws yog deposited nyob ib ncig ntawm lub qhov thiab coated nyob rau hauv lub tshiab raug lub qhov. phab ntsa hauv cov ntawv ci tooj liab, uas yog qhov ua rau muaj kev phom sij rau cov plating tom ntej.
Lub molten resin tseem yuav tawm hauv ib txheej ntawm cov axis kub ntawm lub qhov phab ntsa ntawm lub substrate, uas qhia tau hais tias tsis zoo adhesion rau feem ntau activators, uas yuav tsum tau tsim ib chav kawm ntawm cov tswv yim zoo li stain tshem tawm thiab etchback chemistry. Ib txoj hauv kev uas tsim nyog rau tus qauv ntawm cov ntawv luam tawm Circuit Board yog siv cov ntawv tshwj xeeb uas tsim los ntawm cov viscosity number case los tsim cov nplaum nplaum thiab cov txheej txheem zoo heev ntawm cov phab ntsa sab hauv ntawm txhua lub qhov. Nyob rau hauv txoj kev no, tsis tas yuav siv ntau cov txheej txheem kev kho mob, tsuas yog ib daim ntawv thov kauj ruam, ua raws li thermal curing, tuaj yeem tsim cov txheej txheem txuas ntxiv rau sab hauv ntawm txhua lub qhov phab ntsa, nws tuaj yeem ncaj qha electroplated yam tsis muaj kev kho mob ntxiv. Cov cwj mem no yog cov khoom siv cob qhia uas muaj zog adhesion thiab tuaj yeem yooj yim sib txuas rau feem ntau thermally polished qhov phab ntsa, yog li tshem tawm cov kauj ruam ntawm etch rov qab.
2. Reel linkage hom xaiv plating
Cov pins thiab pins ntawm cov khoom siv hluav taws xob, xws li cov khoom sib txuas, kev sib txuas sib txuas, cov khoom siv hluav taws xob, thiab hloov pauv FPCB boards, yog tag nrho cov plated kom tau txais kev sib cuag zoo thiab kev tiv thaiv corrosion. Txoj kev electroplating no tuaj yeem yog phau ntawv lossis tsis siv neeg, thiab nws yog qhov kim heev los xaiv txhua tus pin ib tus zuj zus rau plating, yog li cov vuam loj yuav tsum tau siv. Feem ntau, ob qhov kawg ntawm cov ntawv hlau dov mus rau qhov yuav tsum tau muaj tuab yog xuas nrig ntaus, ntxuav los ntawm cov tshuaj lom neeg lossis cov txheej txheem, thiab tom qab ntawd xaiv xaiv zoo li npib tsib xee, kub, nyiaj, rhodium, khawm lossis tin-nickel alloy, tooj liab-nickel alloy, Nickel. - txhuas alloy, thiab lwm yam rau kev nruam plating. Nyob rau hauv txoj kev electroplating ntawm kev xaiv plating, ua ntej ntawm tag nrho cov, ib txheej ntawm resisting zaj duab xis yog coated rau ib feem ntawm cov hlau tooj liab ntawv ci phaj uas tsis tas yuav tsum tau plated, thiab tsuas yog xaiv tooj liab ntawv ci ib feem yog plated.
3. Ntiv tes plating
Cov hlau tsis tshua muaj yuav tsum tau plated rau ntawm lub rooj tsavxwm ntug connector, lub rooj tsavxwm ntug protruding tiv tauj los yog tus ntiv tes kub los muab kev tiv thaiv qis dua thiab hnav tsis kam. Cov txheej txheem no yog hu ua ntiv tes kab plating lossis protruding feem plating. Kub feem ntau yog plated rau ntawm cov kev sib cuag ntawm ntug txuas nrog npib tsib xee plating ntawm txheej sab hauv. Cov ntiv tes kub los yog ib feem ntawm lub ntug ntawm lub rooj tsavxwm siv phau ntawv los yog tsis siv neeg plating tshuab. Tam sim no, cov kub plating ntawm qhov txuas txuas lossis cov ntiv tes kub tau plated nrog pog thiab cov hlau lead, Plated nyees khawm hloov.
Cov txheej txheem yog raws li nram no:

1. Tshem tawm cov txheej txheem kom tshem tawm cov tin lossis tin-lead txheej ntawm cov kab sib txuas.
2. Yaug nrog dej ntxuav.
3. txhuam nrog abrasives.
4. Kev ua kom dej yog submerged hauv 10% sulfuric acid.
5. Lub thickness ntawm npib tsib xee plating ntawm cov protruding hu yog 4-5μm.
6. Ntxuav thiab tshem tawm cov dej ntxhia.
7. Kev kho cov tshuaj kub nkag.
8. Kub plating.
9. Kev ntxuav.
10. Qhuav.
4. Txhuam plating
Nws yog cov txheej txheem electrodeposition, thiab tsis yog txhua qhov chaw yog immersed hauv electrolyte thaum lub sij hawm electroplating txheej txheem. Nyob rau hauv cov txheej txheem electroplating no, tsuas yog ib cheeb tsam tsuas yog electroplated, thiab nws tsis cuam tshuam rau tus so. Feem ntau, cov hlau tsis tshua muaj plated ntawm xaiv qhov chaw ntawm lub rooj tsav xwm luam tawm, xws li cov chaw xws li board edge connectors. Txhuam plating yog siv ntau zaus hauv kev kho cov khib nyiab pov tseg hauv cov khw muag khoom siv hluav taws xob. Qhwv ib qho tshwj xeeb anode (anode uas tsis muaj tshuaj lom neeg, xws li graphite) hauv cov khoom nqus dej (paj rwb) thiab siv nws los nqa cov tshuaj plating mus rau qhov chaw uas yuav tsum tau plating.
