Qhov txawv ntawm Nickel-plated tooj liab thiab Tin-plated tooj liab yog dab tsi?

Muaj nuj nqi:Txhua yam txheej txheej muaj qhov zoo sib xws, uas tuaj yeem tiv thaiv corrosion (txhim kho lub peev xwm tiv thaiv oxidation) thiab ua lub luag haujlwm zoo nkauj.

Nickel-plated tooj liab:Tom qab electroplating, nws muaj tshuaj lom neeg ruaj khov nyob rau hauv cov huab cua thiab alkali tov, tsis yooj yim rau hloov xim, yog oxidized saum 600 degrees Celsius, muaj hardness siab, thiab yooj yim rau polish. Qhov tsis zoo yog porosity, thiab nto ntawm npib tsib xee-plated zoo li ci dua. Nws zoo nkaus li du rau tes. Nws kuj muaj zog adhesion thiab hnav tsis kam.

Tooj liab plating:Nws muaj cov tshuaj lom neeg ruaj khov siab, yuav luag insoluble hauv kev daws teeb meem ntawm sulfuric acid, nitric acid thiab hydrochloric acid, thiab muaj kev ua haujlwm zoo vuam. Tin plating tiv thaiv electromagnetic cuam tshuam. Cov tin-plated zoo li dawb, tsis zoo-zoo, thiab yuav muaj ib txheej ntawm grey tin ua npuas ncauj thaum koj kov lawv nrog koj txhais tes.

Daim ntawv thov:

Nyob ntawm daim ntawv thov, nickel lossis tin plating tuaj yeem xaiv.

1. Yog tias nws yog ib feem ntawm qhov tsos, feem ntau xaiv cov nickel plating, uas yog du thiab zoo nkauj, thiab tsis hloov xim tom qab ntsuas kub.

2. Yog tias nws yuav tsum muaj hluav taws xob muaj zog, qhov chaw ntawm cov tooj liab yuav tsum tau tinned.

3. Yog tias nws yog ib qho khoom siv sab hauv, xws li EMI daim thaiv npog ntawm PCB board, nws yog tag nrho cov tin-plated (chim plating), thiab qee cov txheej hauv qab yog npib tsib xee-plated ua ntej thiab tom qab ntawd tin-plated.

Cov hauv qab no yog ib qho kev sib piv ntawm cov kev hloov pauv ua ntej thiab tom qab tin plating thiab npib tsib xee plating ntawm tooj liab tuav:

1. Kev hloov pauv kev hloov pauv ua ntej thiab tom qab tooj liab bar tinning:

Daim duab 1: Lub conductivity ntawm tooj liab bar ua ntej tinning yog 98.6 feem pua ​​IACS

Daim duab 2: Lub conductivity ntawm tooj liab bar tom qab tinning yog ntau dua 98.6 feem pua ​​IACS, uas yog me ntsis siab tshaj qhov ua ntej tinning (qhov nruab nrab pob qhov rooj kuj hloov tau)

2. Kev hloov pauv kev ntsuas ua ntej thiab tom qab nickel plating ntawm tooj liab tuav:

Daim duab 3: Cov conductivity ntawm tooj liab bar ua ntej nickel plating yog 98.6 feem pua ​​​​IACS

Daim duab 4: Lub conductivity ntawm tooj liab bar tom qab npib tsib xee plating yog 75.8 feem pua ​​IACS, uas yog 22.8 feem pua ​​IACS qis dua qhov ua ntej tin plating.

Los ntawm cov kev ntsuam xyuas saum toj no ntawm kev hloov pauv ntawm cov tooj liab bar ua ntej thiab tom qab tin plating thiab npib tsib xee plating, nws tau pom tias thaum ob qho qauv ntawm cov tooj liab bar yog tib yam khoom, qhov conductivity ntawm tooj liab bar nto nce me ntsis tom qab. tin plating, thaum tooj liab bar nto ua hluav taws xob tom qab nickel plating. Tus nqi tau txo qis los ntawm 22.8 feem pua ​​​​IACS, uas yog, qhov kev ua tau zoo tau txo los ntawm 23 feem pua. Yog li ntawd, nws tau pom zoo tias qhov saum npoo ntawm cov tooj liab tau kho nrog tin plating raws li txoj cai zoo tshaj plaws. Yog tias koj yuav tsum xaiv cov txheej txheem nickel-plating nrog qhov ci zoo dua, cov tooj liab yuav tsum tau derated.
