Kub Au Coated Contacts: Ua tiav Kev Lag Luam Txheej Txheem

Kub Au Coated Contacts yog cov khoom siv hluav taws xob sib txuas ua los ntawm txheej txheej txheej (feem ntau yog tooj liab, tooj liab alloy, npib tsib xee{0}}raws li alloy, thiab lwm yam) nrog txheej txheej siab -purity kub (Au) lossis kub alloy. Siv ob qho tib si electroless kub plating los yog cov txheej txheem electroplating, cov txheej kub yog sib npaug rau qhov sib cuag, txhim kho kev sib cuag, tiv thaiv corrosion, thiab hluav taws xob conductivity. Kub-plated contacts yog siv dav hauv cov khoom siv hluav taws xob, hluav taws xob, thiab cov khoom siv hluav taws xob tshiab uas xav tau kev ntseeg siab thiab kev tiv thaiv qis.

Lub ntsiab kom zoo dua ntawm Kub Plating Contacts stems los ntawm lub cev thiab tshuaj lom neeg cov khoom ntawm kub (Au):

1. Kev siv hluav taws xob zoo heev
Kub muaj ib tug resistivity ntawm kwv yees li 2.44 μΩ·cm, tsuas yog me ntsis siab dua nyiaj (1.59 μΩ·cm). Nws tuav tsis tshua muaj kev tiv thaiv txawm nyob rau hauv qhov chaw ntub thiab corrosive.

2. Kev tiv thaiv corrosion heev
Kub yog qhov ruaj khov heev nyob rau hauv huab cua, noo noo, tshuaj tsuag ntsev, thiab ntau yam acidic ib puag ncig, ua kom tsis muaj oxidation.

Kev Ntsuas Tshuaj Tsuag: Kub-plated txheej Ntau dua lossis sib npaug ntawm 0.5 μm tuab tuaj yeem dhau 48-96 teev ntsev tshuaj tsuag yam tsis pom qhov pom kev xeb.

3. Hnav tsis kam thiab ruaj khov
Txawm hais tias kub yog qhov muag muag, alloying (xws li tawv kub plating nrog ntxiv ntawm cobalt los yog npib tsib xee) tuaj yeem ua rau nws cov Vickers hardness mus rau 130-200 HV, ua rau nws lub neej kev pab cuam.

4. Zoo heev Solderability
Au-plated contacts tuaj yeem txuas ncaj qha nrog tin soldering, silver soldering, lossis kub xovxwm vuam, muab cov dej ntub dej zoo thiab txo qhov kev pheej hmoo ntawm cov pob qij txha txias.

5. Kev sib raug zoo ntawm Thickness thiab hluav taws xob kev ua tau zoo

Nyias kub plating (0.05-0.1 μm): Haum rau cov teeb liab terminals; tus nqi qis tab sis nruab nrab hnav tsis kam.

Thick kub plating (0.5-2.5 μm): Tsim nyog rau kev siv ntau zaus plugging thiab unplugging lossis hnyav ib puag ncig, ua kom muaj kev sib cuag.

Kev tsim cov txheej txheem rau kub-plated hluav taws xob tiv tauj yuav tsum tau muaj siab precision thiab sib xws. Cov kauj ruam tseem ceeb suav nrog:

1. Kev npaj substrate

Xaiv lub siab -copper conductivity, tooj liab alloys (xws li tooj dag, beryllium tooj liab), los yog nickel alloys.
Mechanically polish los yog precision stamp rau saum npoo kom paub meej qhov ntev ntev raws li cov qauv tsim (hauv ± 0.01 hli).

2. Nto Pretreatment

Degreasing: Tshem cov roj thiab ua cov khoom seem.
Pickling: Tshem tawm oxide zaj duab xis.
Ua kom muaj zog: Txhim kho kub txheej adhesion.

3. Nickel primer

Ib txheej 1-2 μm npib tsib xee feem ntau yog siv ua ntej kub plating los tiv thaiv kev sib txawv ntawm cov substrate thiab txheej kub thiab tswj cov txheej kub purity.

4. Kub Plating

Hard Gold Plating: Rau Kub Plated Relay Contacts uas nquag ntsaws thiab unplugged.
Mos Kub Plating: Rau hluav taws xob tiv tauj kub plated uas yuav tsum tau soldering.

Lub plating tuab yog tswj tau meej, feem ntau siv online X-ray thickness ntsuas nrog qhov tseeb ntawm ± 0.01 μm.

5. Tshaj tawm -Kev Ua Haujlwm thiab Kev Ntsuas

Kev kuaj ntsev ntsev, kev sib txhuam thiab kev hnav, thiab kev sib cuag tiv thaiv yog ua.
Kev tiv thaiv kev tiv thaiv ib txwm: Tsawg dua lossis sib npaug li 10 mΩ.

1. Kev tiv thaiv qis qis
Kub tsis tsim cov oxide zaj duab xis rau ntawm qhov chaw, tswj kev ruaj ntseg teeb liab kis tau tus mob txawm nyob rau hauv qis tam sim no. Nws yog qhov tsim nyog rau cov ntawv thov uas xav tau cov teeb liab siab ncaj ncees, xws li 5G kev sib txuas lus, ntsuas qhov tseeb, thiab cov khoom siv kho mob.

2. Zoo heev Environmental Resistance
Txawm tias nyob rau hauv siab - kub thiab siab - qhov chaw av noo ntawm 85℃thiab 85% av noo, kev ua haujlwm degradation ntawm Kub Plating Copper Rivets yog qhov tsawg, nrog lub neej ntev tshaj 10 xyoo.

3. Adaptable rau nquag ntsaws thiab tsis tshua muaj tam sim no
Thick Gold Flash Plating Contacts tswj kev tiv thaiv kev hloov pauv tsawg dua 5 mΩ tom qab 5,000 txog 10,000 ntsaws thiab tshem tawm mus, txo cov nqi kho mob.

4. Txo cov nqi tu thiab kev poob qis
Hauv kev lag luam automation, kev tsheb ciav hlau, thiab kev siv hluav taws xob tshiab, kev siv cov Kub Plated Bimetal Contacts tuaj yeem txo qis sijhawm thiab kho cov nqi los ntawm kev sib cuag tsis zoo.

5. Kev txhim kho tag nrho cov kev ntseeg tau
Nyob rau hauv siab -voltage connectors rau lub zog tshiab tsheb thiab aerospace kev sib txuas lus systems, ruaj khov kev sib cuag ncaj qha txiav txim siab system kev ruaj ntseg thiab ua hauj lwm tas mus li.
