Dab tsi yog qhov txawv ntawm kub -plated thiab silver-plated connectors lossis hu?

Electroplating yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws uas siv hauv kev tsim khoom niaj hnub no. Nrog kev loj hlob ntawm Is Taws Nem ntawm Yam (IoT), ntau thiab ntau cov khoom siv txuas nrog, muab kev nkag mus rau cov ntaub ntawv thiab cov ntaub ntawv tam sim. Txawm li cas los xij, qhov ua tau zoo thiab kev ntseeg tau ntawm txhua yam khoom siv hluav taws xob nyob ntawm qhov zoo ntawm kev sib txuas, tshwj xeeb tshaj yog cov plating siv rau ntawm qhov txuas lossis kev sib cuag. Kev plating kom zoo yog qhov tseem ceeb rau kev ua haujlwm ntawm cov cuab yeej txhim khu kev qha, thaum plating tsis zoo tuaj yeem cuam tshuam qhov kev ua tau zoo, kev siv tau, thiab ua haujlwm ntev ntawm lub cuab yeej.

Kub thiab nyiaj yog ob qho tib si plating txheej txheem siv rau plating cov khoom siv hluav taws xob xws li cov khoom sib txuas thiab kev sib cuag, ob qho tib si uas tsim cov kev sib raug zoo thiab kev sib txuas. Silver Plated Contacts thiab Kub Plated Contacts yog dav siv nyob rau hauv ntau yam lag luam. Ob leeg kub thiab nyiaj muaj kev ua haujlwm siab thiab corrosion kuj; Txawm li cas los xij, nyiaj tuaj yeem tsim sulfides (tarnish), thaum kub tuaj yeem yog qhov kev xaiv kim. Nyob rau hauv tsab xov xwm no, peb yuav tham txog qhov sib txawv ntawm cov nyiaj thiab kub connectors thiab thaum twg ib txheej yuav nyiam dua lwm yam.

Kub yog ib qho khoom kim heev (thiab tsis yog{0}}reactive) hlau uas tuaj yeem txhim kho kev sib txuas ntawm ntau yam kev siv hluav taws xob. Cov txiaj ntsig ntawm kev siv Gold Plating Contacts lossis Au Plated Contacts suav nrog:

1. Superior Corrosion Resistance

Kub muaj qhov ua tau zoo heev rau oxidation lossis corrosion piv rau lwm yam hlau. Nyob rau hauv cov xwm txheej uas cov connector hu yuav raug corrosive tshuaj los yog tej yam kev mob, Kub Plated Contacts yuav ua tau zoo oxidation thiab corrosion barrier. Yog li ntawd, kub-plated connectors yog ib qho kev xaiv zoo tshaj plaws rau cov ntawv thov uas cov khoom sib txuas lossis cov neeg sib txuas yuav raug cuam tshuam rau cov kab mob ntau dua.

Cov ntawv thov rau kub -plated connectors muaj xws li siab- ib puag ncig cov av noo los yog nquag thermal cycling, nrog rau cov uas raug corrosive ntsev los yog acids. Hauv cov ntawv thov xav tau ntau dua, hnyav Au Plated Contacts lossis txawm tias duplex kub tso nyiaj yuav tsum tau ua kom muaj kev pov hwm txaus los tshem tawm cov porosity hauv qhov tso nyiaj thiab tsim kom muaj kev tiv thaiv corrosion zoo.

2. High conductivity

Nrog rau tooj liab thiab nyiaj, kub yog qhov thib peb feem ntau conductive hlau nyob hauv lub ntiaj teb. Txawm li cas los xij, kub tsis tsim cov oxides lossis lwm cov tshuaj sib xyaw ua ke, yog li nws tuav nws cov conductivity siab txawm tias qhov kub thiab txias los yog thaum raug corrosive ib puag ncig. Kub lub siab thiab zoo ib yam conductivity ua kom ruaj khov tam sim no txawm nyob rau ntawm qhov tsawg voltages, ua rau nws yog ib qho kev xaiv zoo heev rau cov ntawv siv hluav taws xob uas millivolts thiab milliamps kis tau.

3. Txhim khu kev ruaj ntseg

Electroplated kub tuaj yeem ua alloyed nrog me me ntawm npib tsib xee lossis cobalt kom nce hardness ntawm cov kub ntshiab (<90 knoops) to up to 200 knoops. This hardened gold is often referred to as hard gold. When plated to a sufficient thickness (>50 μin) dhau ntawm electrolytic lossis electroless npib tsib xee puag, tawv kub muab cov txheej txheem ruaj khov uas tiv taus kev sib txuas ntau dua. Vim nws lub ntuj lubricity, Kub Plating Contacts tsis tshua muaj kev cuam tshuam los yog puas.

4. Kev ua haujlwm siab

Vim tias kub yog cov khoom siv hlau, nws yog qhov tsim nyog rau kev sib cuag tau yooj yim thiab cov springs. Kub lub ductility ua rau cov txheej txheem yuav tiv taus ntau yam kev sib cuag. Txawm li cas los xij, Au Plated Contacts lossis springs yuav tsum muaj cov khoom siv hauv paus tsim nyog los xyuas kom meej qhov chaw tiav raws li cov qauv tsim. Thaum electroplating hloov tau yooj yim hu los yog springs, nws yog feem ntau pom zoo kom siv ib tug engineered npib tsib xee (xws li npib tsib xee sulfamate) ua lub hauv paus rau cov kub plating.

5. Solderability

Kub plating yog qhov zoo tshaj plaws nto tiav rau kev tsim cov pob qij txha txhim khu kev qha. Nws tsuas yog xav tau ib qho me me rosin flux thiab tsis tas yuav muaj kua qaub ua kom tsis tu ncua ntub dej.Kub Plated Contactstuaj yeem plated mus rau ze li ntawm txhua lub substrate, nrog rau cov hlau tsis muaj steel hlau los yog cov khoom sib txuas, rau kev sib txuas tom ntej. Feem ntau, nyias, mos kub tso nyiaj ntawm 0.00001 nti ib sab yog txaus los tsim ib tug txhim khu kev qha, solderable kub hu, tab sis hnyav deposits kuj ua tau.

Thaum soldering rau kub electrodeposit, cov kub diffuses mus rau hauv lub solder sib koom los ntawm ib tug mechanism hu ua solid{0}}state diffusion. Kev saib xyuas yuav tsum tau ua kom ntseeg tau tias cov ntsiab lus kub hauv qhov sib koom ua ke tsis tshaj 3% los ntawm qhov hnyav, vim qhov no tuaj yeem ua rau embrittlement ntawm solder sib koom nws tus kheej.

6. Tsis yog-magnetic

Thaum kawg, kub tsis yog{0}}magnetic. Qhov no yog qhov zoo nyob rau hauv cov xwm txheej uas electromagnetic teb tuaj yeem ua rau cuam tshuam. Piv txwv li, kub plating tej zaum yuav haum rau connectors siv nyob rau hauv cov khoom kho mob xws li magnetic resonance imaging (MRI) scanners.
