1. Immersion Kub yog dab tsi?
Yuav kom muab tso rau nws yooj yim, immersion kub yog siv cov tshuaj deposition los tsim ib tug hlau txheej nyob rau saum npoo ntawm lub Circuit Court board los ntawm ib tug tshuaj oxidation-txo cov tshuaj tiv thaiv.

2. Vim li cas peb thiaj yuav tsum muab kub tso rau hauv?
Cov tooj liab ntawm lub rooj tsav xwm hauv Circuit Court feem ntau yog tooj liab, thiab cov pob qij txha tooj liab tau yooj yim oxidized nyob rau hauv cov huab cua, uas yuav ua rau cov conductivity, uas yog, tsis zoo tin noj los yog kev sib cuag tsis zoo, thiab txo qhov kev ua tau zoo ntawm lub rooj tsav xwm Circuit Court.

Tom qab ntawd nws yog ib qho tsim nyog los ua qhov kev kho saum npoo ntawm cov tooj liab solder pob qij txha. Immersion kub yog los plate kub rau nws. Kub tuaj yeem thaiv cov tooj liab hlau thiab cua kom tiv thaiv oxidation. Yog li ntawd, Immersion Kub yog ib txoj kev kho rau saum npoo oxidation. Nws yog tshuaj lom neeg cov tshuaj tiv thaiv ntawm tooj liab. Qhov saum npoo yog them nrog txheej kub, kuj hu ua kub.

3. Cov txiaj ntsig ntawm kev kho saum npoo zoo li immersion kub yog dab tsi?
Qhov kom zoo dua ntawm cov txheej txheem immersion kub yog tias cov xim tso rau ntawm qhov chaw yog qhov ruaj khov thaum lub voj voog luam tawm, qhov ci ntsa iab zoo heev, txheej txheej yog du heev, thiab cov solderability zoo heev.

Immersion kub feem ntau muaj qhov tuab ntawm 1-3 Uinch. Yog li ntawd, lub thickness ntawm kub uas ua los ntawm qhov chaw kho mob txoj kev ntawm Immersion kub yog feem ntau thicker. Yog li ntawd, txoj kev kho saum npoo ntawm Immersion Kub feem ntau yog siv rau hauv cov laug cam, cov ntiv tes kub thiab lwm yam khoom siv hluav taws xob. Vim hais tias kub muaj zog conductivity, zoo oxidation kuj thiab ntev kev pab cuam lub neej.

4. Dab tsi yog qhov txiaj ntsig ntawm kev siv immersion kub Circuit Court boards?
1. Immersion kub phaj yog ci xim, zoo xim thiab txaus nyiam nyob rau hauv tsos.
2. Cov qauv siv lead ua tsim los ntawm immersion kub yog yooj yim rau vuam dua li lwm yam kev kho saum npoo, tuaj yeem ua tau zoo dua thiab ua kom zoo.
3. Vim hais tias lub immersion kub board tsuas muaj npib tsib xee thiab kub ntawm lub ncoo, nws yuav tsis cuam tshuam rau lub teeb liab, vim hais tias cov teeb liab kis tau tus mob nyob rau hauv daim tawv nqaij nyhuv yog nyob rau hauv lub tooj liab txheej.
4. Cov khoom siv hlau ntawm kub yog qhov ruaj khov, cov qauv siv lead ua yog denser, thiab cov tshuaj tiv thaiv oxidation tsis yooj yim tshwm sim.
5. Txij li thaum lub immersion kub board tsuas muaj npib tsib xee thiab kub ntawm lub ncoo, solder daim npog qhov ncauj ntawm lub Circuit Court thiab cov tooj liab txheej yog ruaj khov dua, thiab nws tsis yog ib qho yooj yim ua rau micro short circuits.
6. Qhov project yuav tsis cuam tshuam qhov kev ncua deb thaum them nyiaj.
7. Kev ntxhov siab ntawm cov phaj kub immersion yog yooj yim los tswj.

5. Immersion kub thiab kub ntiv tes
Cov ntiv tes kub yog qhov ncaj tshaj, lawv yog tooj dag, lossis cov neeg xyuas pib.

Yuav kom paub meej dua, vim tias kub muaj zog oxidation tsis kam thiab muaj zog conductivity, cov khoom txuas nrog lub cim xeeb ntawm lub cim xeeb stick yog plated nrog kub, ces tag nrho cov teeb liab kis tau los ntawm cov ntiv tes kub.

Vim tias cov ntiv tes kub yog tsim los ntawm ntau cov kab hluav taws xob daj, qhov saum npoo yog kub-plated thiab cov kab hluav taws xob sib txuas tau teem caij zoo li cov ntiv tes, yog li lub npe.

Nyob rau hauv layman cov ntsiab lus, tus ntiv tes golden yog qhov txuas ntawm lub cim xeeb stick thiab lub cim xeeb qhov, thiab tag nrho cov teeb liab kis tau los ntawm tus ntiv tes golden. Cov ntiv tes kub yog tsim los ntawm ntau cov kev sib cuag golden. Cov ntiv tes kub yog tiag coated nrog ib txheej ntawm kub ntawm tooj liab clad board los ntawm ib tug tshwj xeeb txheej txheem.

Yog li ntawd, qhov sib txawv yooj yim yog tias immersion kub yog txheej txheem kev kho mob saum npoo rau Circuit Court boards, thiab cov ntiv tes kub yog cov khoom uas muaj cov teeb liab sib txuas thiab conduction ntawm Circuit Court board.

Hauv kev ua lag luam tiag tiag, cov ntiv tes kub yuav tsis yog kub ntawm qhov chaw.

Vim yog tus nqi kub kub, feem ntau nco tau tam sim no hloov los ntawm tin plating. Tin cov ntaub ntawv tau nrov txij li xyoo 1990. Tam sim no, "golden fingers" ntawm motherboards, nco thiab graphics phaib yuav luag tag nrho ua los ntawm tin. Cov ntaub ntawv, tsuas yog ib feem ntawm cov ntsiab lus ntawm kev ua haujlwm siab ntawm cov servers / chaw ua haujlwm yuav txuas ntxiv kub-plated, uas yog ib txwm kim.
