Lub hauv paus ntsiab lus thiab tswj cov ntsiab lus ntawm ENIG

Kev kho saum npoo ntawm ENIG yog ib qho ntawm cov txheej txheem kev kho mob saum npoo av hauv kev lag luam hluav taws xob, uas tuaj yeem ua rau saum npoo ntawm cov laug cam muaj qhov ua tau zoo, tiv thaiv corrosion, thiab oxidation tsis kam. Txoj hauv kev tseem ceeb kom ua tiav cov txiaj ntsig no yog tsim cov txheej txheem ntawm cov ntawv hlau rau ntawm qhov chaw ntawm lub rooj tsav xwm luam tawm los ntawm immersion plating, uas plays lub luag haujlwm tiv thaiv thiab ntxiv dag zog.

Ua ntej, qhov saum npoo ntawm lub rooj tsavxwm luam tawm yuav raug ntxuav los ntawm cov txheej txheem xws li polishing, tu, thiab tshem tawm cov roj stains, yog li cov ntawv hlau txuas ntxiv tom ntej tuaj yeem ua tau zoo dua rau ntawm qhov chaw. Tom qab ntawd, ib txheej ntawm npib tsib xee thiab txheej kub yog electrolytically tso rau ntawm lub rooj tsavxwm tooj liab. Nickel thiab tooj liab muaj kev sib raug zoo zoo thiab tuaj yeem ruaj khov ntawm tooj liab, thaum kub yog cov hlau muaj txiaj ntsig zoo nrog cov muaj zog tiv thaiv oxidation thiab corrosion, thaum tseem tiv thaiv cov tsub zuj zuj ntawm inert tshuaj.

Thaum lub sij hawm immersion txheej txheem, lub Rooj Tswjhwm Saib tau ib tug tshuaj tiv thaiv nrog ib tug hlau tov kom maj mam txo cov hlau ions xws li kub thiab tooj liab nyob rau hauv cov tshuaj, depositing nyob rau saum npoo ntawm lub luam Circuit Court board los ua ib tug txheej ntawm hlau ntawv. Lub deposition thickness thiab cov duab tuaj yeem hloov kho raws li qhov xav tau. Cov ntawv ci hlau tawv yog cov khoom siv tiv thaiv zoo tshaj plaws uas tuaj yeem tiv thaiv cov ntawv luam tawm hauv Circuit Court los ntawm kev cuam tshuam los ntawm cov pa roj, kua, thiab hluav taws xob cov teeb liab, yog li kev tswj xyuas lub neej zoo thiab kev ruaj ntseg ntawm cov ntawv luam tawm Circuit Board.

Tom qab kub plating kev kho mob, qhov saum npoo ntawm lub rooj tsav xwm Circuit Court yuav ua du, tiaj tus, ci iab, thiab muaj qhov zoo weldability thiab corrosion kuj. Vim qhov zoo tshaj plaws conductivity ntawm cov ntawv hlau, kev sib kis tau zoo ntawm cov ntawv luam tawm Circuit Board kuj tau txhim kho zoo. Nyob rau tib lub sijhawm, cov ntawv hlau hlau kuj tseem tuaj yeem ua cov txheej txheem sib txuas zoo ntawm cov rooj sib tham hauv Circuit Court thiab lwm yam khoom siv, kev sib txuas zoo dua, thiab txhim kho kev ntseeg tau thiab ruaj khov ntawm cov khoom siv hluav taws xob.

ENIG nto kev kho mob yog cov txheej txheem kho saum npoo uas tuaj yeem tsim cov txheej txheem ntawm cov hlau sib txuas rau saum npoo ntawm cov laug cam, yog li txhim kho lawv cov conductivity, corrosion kuj, thiab kev ntseeg tau. Lub hauv paus ntsiab lus ntawm ENIG nto kev kho mob yog tsuas yog siv cov tshuaj electrochemical los tso cov hlau rau ntawm qhov chaw ntawm lub substrate, tsim cov hlau sib txuas.

Tus nqi ntawm ENIG nto kev kho mob yog tus nqi siab, tab sis nws muaj ntau yam kev siv thiab tuaj yeem siv rau hauv thaj chaw xws li hluav taws xob, khoom siv sib txuas lus, kev lag luam tsheb, khoom siv kho mob, thiab lwm yam. Hauv kev lag luam hluav taws xob, ENIG nto kho mob yog dav siv. hauv kev tsim cov ntawv luam tawm Circuit Board (PCBs). Hauv cov khoom siv sib txuas lus, kev kho kub saum npoo yog feem ntau siv los txhim kho kev ua haujlwm ntawm cov suab nrov qis amplifiers.

Cov kev cai rau kev kho saum npoo ntawm ENIG yog nruj heev, thiab kev tswj hwm nruj ntawm kev kho mob yuav tsum tau ua kom nws zoo. Qhov no suav nrog kev tswj hwm yam xws li kev ua haujlwm kub, concentration, thiab sijhawm. Nyob rau tib lub sijhawm, kev tswj hwm nruj yog xav tau rau cov khoom lag luam ua tiav kom ntseeg tau tias lawv ua tau raws li ntau yam kev xav tau tshwj xeeb.

ENIG nto kev kho mob ntawm cov ntawv luam tawm hluav taws xob tuaj yeem muab kev txhawb nqa zoo thiab lav rau kev ua haujlwm ntawm cov khoom siv hluav taws xob ib txwm muaj, ua rau saum npoo ntawm cov ntawv luam tawm Circuit Court boards muaj kev ua tau zoo thiab kev pabcuam lub neej. Los ntawm kev siv cov thev naus laus zis no, kev ua haujlwm zoo thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob kuj tseem yuav ua kom zoo dua qub.
