1. Ntiv tes plating
In PCB pov thawj, tsis tshua muaj hlau yog plated rau ntawm lub rooj tsavxwm ntug connector, board edge protruding contact los yog kub ntiv tes los muab kev sib cuag tsis tshua muaj thiab siab hnav tsis kam, uas yog hu ua ntiv tes plating los yog protruding zos plating.Cov txheej txheem yog raws li nram no:
1) tev tawm cov txheej thiab tshem tawm cov tin lossis tin txhuas txheej ntawm qhov sib cuag.
2) yaug nrog dej.
3) txhuam nrog abrasive.
4) ua kom diffuse hauv 10% sulfuric acid.
5) npib tsib xee plating thickness ntawm protruding hu yog 4-5 μ m.
6) Ntxuav kom tshem tawm cov dej ntxhia.
7) pov tseg ntawm kub soaking tov.
8) kub plating.
9) ntxuav.
10) ziab.
2. Ntawm plating
Muaj ntau txoj hauv kev los teeb tsa cov txheej txheem tsim nyog electroplating ntawm lub qhov phab ntsa ntawm lub substrate drilling, uas yog hu ua lub qhov phab ntsa ua kom muaj kev siv hauv kev lag luam.Kev lag luam noj cov txheej txheem ntawm nws cov ntawv luam tawm yuav tsum muaj ntau lub tank cia nruab nrab, txhua tus muaj nws tus kheej tswj thiab kev saib xyuas.Ntawm electroplating yog cov txheej txheem tsim nyog tsim nyog ntawm cov txheej txheem drilling.Thaum lub laum me ntsis laum los ntawm cov ntawv ci tooj liab thiab nws cov hauv paus substrate, lub tshav kub generated condenses lub insulating hluavtaws resin uas yog feem ntau ntawm cov substrate, thiab cov condensed resin thiab lwm yam drilling khib nyiab nyob ib ncig ntawm lub qhov thiab yog coated nyob rau hauv lub tshiab exposed lub qhov phab ntsa. nyob rau hauv cov ntawv ci tooj liab, thiab cov condensed resin tseem yuav tawm hauv ib txheej kub axis ntawm lub qhov phab ntsa ntawm lub substrate;Nws qhia tau hais tias tsis zoo adhesion rau feem ntau activators, uas yuav tsum tau kev txhim kho ntawm ib yam ntawm cov cuab yeej zoo ib yam li cov tshuaj ua ntawm stain tshem tawm thiab corrosion rov qab.
Ib txoj hauv kev zoo dua rau kev pov thawj PCB yog siv cov ntawv tshwj xeeb uas tsis tshua muaj viscosity number case, uas muaj zog adhesion thiab tuaj yeem yooj yim txuas rau feem ntau kub polished qhov phab ntsa, yog li tshem tawm cov kauj ruam ntawm qhov rov qab.
3.Cov menyuam txuas txuas xaiv plating
Cov pins thiab cov pins ntawm cov khoom siv hluav taws xob, xws li cov khoom sib txuas, sib txuas sib txuas, cov khoom siv hluav taws xob thiab cov ntawv luam tawm yooj yim, yog xaiv plated kom ua tiav kev sib cuag zoo thiab kev tiv thaiv corrosion.Txoj kev electroplating no tuaj yeem yog phau ntawv lossis tsis siv neeg.Nws yog kim heev kom tsis txhob xaiv plating rau txhua tus pin ib leeg, yog li batch vuam yuav tsum tau siv.Hauv kev xaiv cov txheej txheem plating, thawj txheej txheej ntawm cov yeeb yaj kiab inhibitor rau ntawm qhov chaw ntawm cov ntawv ci hlau uas tsis xav tau electroplating, thiab tsuas yog tso tseg electroplating ntawm cov ntawv ci tooj liab.
4.Txhuam plating
Txhuam plating yog siv tshuab electrostacking, uas tsuas yog nres electroplating nyob rau hauv ib qho chaw txwv thiab tsis muaj kev cuam tshuam rau lwm qhov chaw.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 dav hauvelectronic assembly rhiavlos kho cov kab hluav taws xob pov tseg.
