Dab tsi yog qhov txawv ntawm kub plating thiab immersion kub

Immersion kub adopts txoj kev ntawm tshuaj deposition. Ib txheej txheej yog tsim los ntawm cov tshuaj tiv thaiv redox. Feem ntau, lub thickness yog thicker.

Kub plating siv lub hauv paus ntsiab lus ntawm electrolysis, tseem hu ua electroplating. Feem ntau lwm yam kev kho hlau saum npoo kuj tseem electroplated.

Hauv kev siv cov khoom siv tiag tiag, 90 feem pua ​​​​ntawm cov phaj kub yog cov phaj kub immersion, vim tias cov hlau tsis zoo ntawm cov phaj kub plated yog nws qhov tsis txaus, thiab nws kuj yog qhov laj thawj ncaj qha vim li cas ntau lub tuam txhab tso cov txheej txheem kub plating!

Cov txheej txheem kub immersion tso ib lub npib tsib xee-kub txheej nrog cov xim ruaj khov, ci ntsa iab zoo, cov txheej txheem du thiab zoo solderability ntawm qhov chaw ntawm cov ntawv luam tawm. Yeej nws tuaj yeem muab faib ua plaub theem: kev kho ua ntej (roj tshem tawm, micro-etching, ua kom, tom qab dipping), nickel immersion, kub immersion, tom qab kho (khoom kub ntxuav, DI ntxuav, ziab). Lub thickness ntawm immersion kub yog nyob nruab nrab ntawm 0.025-0.1um.

Kub yog siv nyob rau hauv kev kho deg ntawm Circuit Court boards, vim hais tias kub muaj zog conductivity, zoo oxidation kuj, thiab lub neej ntev. Nws feem ntau yog siv rau hauv cov laug cam, cov ntiv tes kub, thiab lwm yam. Qhov tseem ceeb tshaj plaws ntawm qhov sib txawv ntawm cov laug cam thiab cov laug cam yog cov kub-plated yog tawv kub ( hnav-resistant), immersion kub yog mos kub (tsis hnav- resistant).

1. Cov qauv siv lead ua tsim los ntawm immersion kub thiab kub plating yog txawv. Lub thickness ntawm immersion kub yog ntau thicker tshaj qhov kub plating. Immersion kub yuav golden daj, uas yog daj ntau dua kub plating (qhov no yog ib txoj hauv kev kom paub qhov txawv kub plating thiab immersion kub). a), cov kub-plated yuav yog dawb me ntsis (xim ntawm npib tsib xee).

2. Cov qauv siv lead ua tsim los ntawm immersion kub thiab kub plating yog txawv. Piv nrog kub plating, immersion kub yog yooj yim dua rau vuam thiab yuav tsis ua rau vuam tsis zoo. Qhov kev ntxhov siab ntawm cov phaj kub immersion yog yooj yim rau kev tswj, thiab rau cov khoom nrog kev sib txuas, nws yog qhov zoo dua rau kev ua haujlwm ntawm kev sib txuas. Nyob rau tib lub sijhawm, nws yog qhov tseeb vim tias immersion kub yog softer dua kub plating, yog li cov ntiv tes kub ntawm immersion kub phaj tsis hnav-resistant (qhov tsis zoo ntawm immersion kub phaj).

3. Lub immersion kub board tsuas muaj nickel-kub ntawm lub ncoo. Kev sib kis ntawm cov teeb liab hauv cov nyhuv ntawm daim tawv nqaij yog nyob rau hauv cov txheej tooj liab thiab yuav tsis cuam tshuam rau lub teeb liab.

4. Piv nrog kub plating, immersion kub muaj ib tug denser siv lead ua qauv thiab tsis yooj yim rau oxidation.

5. Nrog rau qhov yuav tsum tau ua ntawm Circuit Court board ua kom raug, cov kab dav thiab qhov sib nrug tau mus txog hauv qab 0.1mm. Kub plating yog ua rau luv luv ntawm cov xov hlau kub. Lub immersion kub phaj tsuas muaj npib tsib xee kub ntawm lub ncoo, yog li nws tsis yog yooj yim los tsim ib tug luv luv Circuit Court ntawm kub hlau.

6. Lub immersion kub board tsuas muaj npib tsib xee-kub ntawm lub ncoo, yog li kev sib xyaw ua ke ntawm lub npog ntsej muag ntawm lub voj voog thiab cov txheej tooj liab muaj zog dua. Qhov project yuav tsis cuam tshuam qhov sib nrug thaum them nyiaj.

7. Rau cov laug cam uas xav tau ntau dua, cov kev xav tau ntawm flatness yog qhov zoo dua, thiab feem ntau siv immersion kub. Immersion kub feem ntau tsis tshwm sim dub ncoo tshwm sim tom qab sib dhos. Lub flatness thiab kev pab cuam lub neej ntawm immersion kub phaj yog zoo dua li ntawm cov kub-plated phaj.
