Copper hlau tinning yog dav siv nyob rau hauv zus tau tej cov xov hlau, cables, thiab enameled xov hlau. Lub tin txheej yog ci thiab silvery dawb, uas tuaj yeem ua rau kom cov weldability thiab kho kom zoo nkauj ntawm tooj liab tsis cuam tshuam rau hluav taws xob conductivity. Nws tuaj yeem siv rau hauv kev lag luam hluav taws xob, rooj tog zaum, ntim khoom noj, thiab lwm yam Anti-oxidation, ua rau kom muaj kev zoo nkauj ntawm tooj liab workpieces. Tsis xav tau cov khoom siv electroplating, tsuas yog yuav tsum tau tsau, yooj yim thiab yooj yim, thiab tuaj yeem plated nrog tuab tin. [1]
Kev taw qhia tshwj xeeb
1. Tinned tooj liab hlau muaj zoo heev solderability.
2. Raws li lub sij hawm hloov, cov solderability tseem zoo thiab tuaj yeem khaws cia rau lub sijhawm ntev.
3. Qhov saum npoo yog du, ci thiab moist.
4. Kev ua haujlwm ruaj khov thiab txhim khu kev qha, ua kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo.
Lub cev thiab tshuaj ntsuas ntsuas
1. Kev nqus tshwj xeeb: 1.04 ~ 1.05
2. PH: 1.0 ~ 1.2
3. Cov tsos: tsis muaj xim tsis muaj pob tshab kua
txheej txheem ntws
Degreasing ntawm tooj liab qhov chaw - pickling los yog polishing - ob ntxuav - electroless tin plating - peb ntxuav - qhuav nyob rau hauv lub sij hawm nrog cua txias - kuaj.
Electroless tin plating: Ntxiv 8 ~ 10g / kg ntawm tin plating additives rau tin plating dej ua ntej siv. Qhov kub ntawm immersion tin yog ib txwm kub ~ 80 ℃, thiab lub sij hawm ntawm immersion tin yog 15 feeb. Thaum lub sij hawm txheej txheem ntawm tin plating, cov tshuaj plating yuav tsum maj mam nplawm los yog lub workpiece yuav tsum tau maj mam muab tig. . Rov qab soaking yuav ua rau kom lub thickness ntawm tin txheej.
Cov kev ceev faj
Cov tooj liab ua haujlwm tom qab micro-etching yuav tsum tau muab tso rau hauv cov tin plating tov nyob rau hauv lub sij hawm tom qab ntxuav los tiv thaiv cov tooj liab nto los ntawm oxidized dua thiab cuam tshuam qhov zoo ntawm txheej.
Thaum lub tinning efficiency poob, 1.0% tinning additive yuav muab ntxiv, thiab nws yuav siv tau tom qab stirring tusyees.
