Dab tsi yog Kub Plated Pcb Board

Muaj ntau yam txheej txheem kev kho mob saum npoo rau PCB boards, xws li tshuaj tiv thaiv oxidation, tin spraying, txhuas-dawb txau tin, immersion kub, immersion tin, immersion silver, hard kub plating, tag nrho board kub plating, kub ntiv tes, nickel palladium kub OSP thiab lwm yam. Yog li dab tsi yog txheej txheem pcb kub plating?

Kub plating tseem hu ua "nyuaj kub". Tus nqi ua ntawm kub-plated PCB Circuit Court boards kuj yog siab. Raws li ib txwm muaj, muaj ntau thiab ntau daim ntawv thov ntawm tin spraying. Txawm li cas los xij, raws li kev sib koom ua ke ntawm IC tau nce siab thiab siab dua, qhov ntau thiab denser IC pins yog. (Piv txwv li: cov khoom siv nco nco), ntau thiab ntau cov laug cam yog xaiv cov txheej txheem kub plating. PCB kub plating yog tsuas yog los ntawm electrolysis los yog lwm yam electroplating chemical txoj kev los mus txuas kub hais rau saum npoo ntawm lub Circuit Court board los ua ib tug nyias txheej ntawm kub. Vim muaj zog adhesion ntawm kub plating, qhov zoo tshaj plaws ntawm cov txheej txheem pcb kub plating yog nws cov hardness siab thiab muaj zog hnav tsis kam.

Qhov txawv ntawm kub plating thiab immersion kub txheej txheem:

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 tsis kam thiab lub neej ntev, thiab feem ntau yog siv nyob rau hauv cov laug cam, kub ntiv tes boards, thiab lwm yam. Qhov tseem ceeb tshaj qhov sib txawv ntawm kub-plated boards thiab immersion kub. Cov laug cam yog kub-plated yog kub 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). 1), cov kub-plated yuav yog dawb me ntsis (xim 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 nquag rau luv luv Circuit Court ntawm kub hlau. 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 zoo dua, thiab immersion kub feem ntau yog siv, thiab qhov tshwm sim ntawm lub ncoo dub tom qab sib dhos yog feem ntau tsis tshwm sim los ntawm immersion kub. Lub flatness thiab kev pab cuam lub neej ntawm immersion kub phaj yog zoo dua li ntawm cov kub-plated phaj.

6- txheej txheej PCB kub plating txheej txheem:

Cov kua nplaum xiav-coated: Tsuas yog nthuav tawm lub ntsej muag ntawm lub rooj tsavxwm uas yuav tsum tau plated nrog npib tsib xee-kub, thiab lub peev xwm conductive yuav tsum ua raws li cov kev taw qhia ntawm lub rooj tsavxwm; Reel kua nplaum: Tsis txhob siv cov ntawv kub reel los tiv thaiv cov nplaum nplaum los ntawm cov kua nplaum; Sab saum toj phaj → Pickling: Tshem tawm tooj liab nto oxidation txheej; dej ntxuav → sib tsoo pawg thawj coj saib: txhawm rau ntxuav cov tooj liab ntxiv thiab tshem tawm qhov tsis xws luag ntawm tooj liab; Kev ntxuav dej → DI dej ntxuav → nickel plating → dej ntxuav → DI dej ntxuav → dej ntxuav → kub plating → recycling → ob-theem dej ntxuav → board tshem tawm → xiav kua nplaum tearing → board ntxhua khaub ncaws → ntxuav tsheb
