Kev sib piv ntawm cov yam ntxwv thiab daim ntawv thov ntawm ci tin thiab mist tin hauv tin plating

1. Kev sib piv ntawm cov yam ntxwv ntawm ci tin thiab mist tin

1) Cov yam ntxwv ntawm ci tin

Qhov zoo: ci tin plating vim yog qhov sib ntxiv ntawm tus neeg sawv cev gloss hauv cov tshuaj plating, ua rau cov txheej txheem crystallization ntau dua. Cov qauv zoo crystalline no pab txhim kho lub gloss thiab kev zoo nkauj ntawm qhov chaw. Nrog zoo gloss thiab muaj kev cuam tshuam, nws tsis yooj yim los tawm cov ntiv tes. Thiab tus nqi muaj qhov zoo dua.

Disadvantages: Kev siv lub teeb ci tin lub teeb, cov hlau muaj ntau cov organic teeb meem ua rau tsis zoo weldability, tsis zoo vuam kev ua tau zoo txhais tau hais tias nws yog ib qho yooj yim los tsim tin whiskers ntawm kub kub, yuav tsim ib tug luv luv Circuit Court ntawm conductors, cuam tshuam rau hluav taws xob kev ua tau zoo. Nyob rau tib lub sijhawm, qhov kub thiab txias kuj tsis zoo, yooj yim hloov xim ntawm qhov kub thiab txias.

2) Cov yam ntxwv ntawm cov hmoov av tin

Qhov zoo: Mist tin yog zoo dua li ci tin weldability thiab tin tsis kam (saib daim duab hauv qab no), pos huab tin vim qhov ntxhib crystallization, feem ntau kuj muaj qhov kub thiab txias zoo dua, pos huab tin siv lead ua qauv zoo dua rau kev tswj xyuas kev ncaj ncees ntawm cov qauv ntawm kub kub, txo oxidation thiab deformation. Cov tin ci ntsa iab tsis yooj yim los tshwm rau theem nrab melting, ci tin tej zaum nyob rau hauv lub cub tawg yuav tshwm sim cov tsos ntawm melting tin txheej.

Disadvantages: Lub txheej txheej yog matte los yog pos huab nyhuv, tsis tshua muaj gloss, kuj ntxhib crystallization, yooj yim tawm cov ntiv tes, tab sis kuj ntshai ntawm khawb, weldability yog zoo, tus nqi kuj yog siab.

2. Generalized daim ntawv thov scenario sib piv

Ci tin plating feem ntau yog siv rau cov ntawv thov uas yuav tsum tau ua kom zoo nkauj thiab zoo nkauj, thiab tsim nyog rau cov ntawv thov uas xav tau kom muaj kev cuam tshuam saum npoo los yog tsom rau cov tsos zoo, xws li cov khoom sib txuas hauv cov khoom zoo nkauj lossis cov khoom siv hluav taws xob. Nyob rau tib lub sijhawm, cov txheej txheej ntawm cov tin ci kuj muaj cov khoom siv hluav taws xob zoo thiab kev ua haujlwm vuam, thiab tseem tsim nyog rau lub sijhawm uas muaj hluav taws xob siab thiab kev sib cuag tsis zoo.

Qhov saum npoo ntawm cov pos nphuab yog matte lossis pos huab, thiab tsis muaj gloss zoo li cov tin ci. Cov txheej no feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau txo qis kev xav lossis txhim kho adhesion, xws li cov khoom hauv cov cuab yeej kho qhov muag, lossis cov khoom siv kho kom zoo nkauj uas yuav tsum tau ua kom tsis muaj gloss.

Hauv cov ntsiab lus, kev xaiv ntawm cov txheej txheem tinning nyob ntawm cov kev thov tshwj xeeb, xws li kev zoo nkauj, hluav taws xob conductivity, weldability thiab qhov xav tau los txo qhov kev xav ntawm qhov chaw. Thaum xaiv cov txheej txheem tinning, cov kev ua tau zoo thiab kev siv ib puag ncig ntawm cov khoom kawg yuav tsum tau txiav txim siab.
