Yuav Ua Li Cas Xaiv Cov Copper Thickness Rau Thick Copper Pcb?

1.Vim li cas tooj liab thickness txiav txim siab kab hauv qab ntawm pcb kev ntseeg tau?
Tej zaum koj yuav tsis tau them nyiaj ntau rau lub thickness ntawm cov tooj liab txheej ntawm lub pcb, tab sis nws yeej txiav txim siab npaum li cas tam sim no cov khoom muaj peev xwm tiv taus, siab npaum li cas lub tshav kub tiam, thiab ntev npaum li cas nws lifespan yuav ua tau.
Cia peb muab ib qho piv txwv yooj yim--
Copper thickness=ntau txoj kab ntawm txoj kev loj
Muaj ob peb txoj hauv kev (tooj liab yog nyias dhau), ua rau muaj kev sib tsoo thiab cua sov hnyav;
Muaj ntau txoj kab (tuab tooj liab), txawm tias tsis muaj kev cuam tshuam, tus nqi siab thiab kev ua haujlwm nyuaj dua.

Cov tuab tooj liab luam tawm Circuit Board yog yuav luag tus qauv hauv cov teb xws li lub zog tshiab, lub zog cia, siab - lub zog tsav, thiab cov khoom siv fais fab. Shenzhen Pulin Circuit muaj cov txheej txheem paub tab thiab kev xa khoom hauv kev tsim khoom loj ntawm 3-oz ~ 6oz tuab tooj liab PCBs, thiab tau muab cov kev daws teeb meem rau ntau pua lub siab tam sim no thiab cov haujlwm tshiab zog.

2.Dab tsi yog cov qauv rau pcb tooj liab thickness?
Hauv kev lag luam pcb, tooj liab tuab feem ntau qhia hauv ounces (oz), uas feem ntau yog hais txog qhov hnyav ntawm cov ntawv ci tooj liab ib square feet.

Hloov mus rau thickness raws li nram no:

Tip: In the industry, printed circuit boards with a size of ≥ 2oz are commonly referred to as thick copper plates, while printed circuit boards with a size of>10oz yog suav tias yog ultra tuab daim hlau.

3.Extended lifespan 3. Qhov twg yog tuab tooj liab luam Circuit Court boards siv? Kuv puas tuaj yeem siv nws?
Txhawm rau txiav txim siab seb koj xav tau cov tooj liab pcb tuab, koj tuaj yeem xa mus rau cov xwm txheej hauv qab no:
Current>5A thiab ntev Circuit Court
Muaj cov khoom siv fais fab uas muaj cua sov hnyav rau ntawm lub rooj tsavxwm
Cov khoom yuav tsum tau khiav ntawm tag nrho cov load rau lub sij hawm ntev
Lub ambient kub yog siab thiab yuav tsum tau rau cua sov dissipation

Common applications:
Muaj fais fab mov, photovoltaic inverter, lub zog cia system
Tshiab zog tsheb OBC, BMS, siab-voltage faib chav tsev
High power motor drive, charging station, rail transit power supply
Cov tub rog tshwj xeeb thiab cov cuab yeej siv dav hlau

4. Kev cuam tshuam ntawm tooj liab thickness ntawm kev ua haujlwm
Cov tooj liab tuab tuaj yeem tsis tsuas yog nce lub peev xwm nqa tam sim no, tab sis kuj txo qhov kub thiab txias thiab ua kom ntev kev pab cuam lub neej. Rau ib qho piv txwv yooj yim:

Nyob rau hauv tib lub 10A tam sim no, qhov kub nce ntawm 3oz tooj liab tuab tuaj yeem txo los ntawm ntau dua 20℃piv rau 1oz tooj liab tuab, uas yog qhov tseem ceeb rau lub neej ntawm cov khoom siv hluav taws xob.

Kev sib piv Table:

Yuav ua li cas yog tias muaj ntau txoj kev xaiv rau tooj liab thickness? (Cov Lus Qhia Txog Tus Neeg Siv Khoom)
Txawm hais tias tuab tooj liab muaj ntau yam txiaj ntsig, nws tsis tas yuav yog qhov tuab zoo dua. Tej teeb meem uas yuav tshwm sim muaj xws li:
1. Tus nqi nce: Copper foil consumables, electroplating lub sij hawm, thiab cov nqi ua tau nce tag nrho.
2. Cov kev txwv ntawm kev sib txuas: Qhov tuab ntawm cov tooj liab, qhov kev txwv ntau dua muaj nyob ntawm qhov tsawg kawg nkaus kab dav / qhov sib txawv.
3. Cov duab nraaj tsawg zuj zus: etching nyuaj siab, thiab cov npoo yog qhov tsis zoo.
4. Ntau lub sij hawm xa tuaj: tuab tooj liab lamination thiab lub sijhawm ua haujlwm ntev dua, feem ntau 1-3 hnub ntev dua li cov ntawv luam tawm hauv Circuit Court.
