Copper Thickness ntawm PCB: Nkag siab 1-Ounce Thickness

Yog tias koj nyob hauv kev lag luam luam tawm Circuit Board (PCB) kev lag luam, tej zaum koj yuav ntsib cov lus nug: "Qhov tuab ntawm 1 ooj tooj liab ntawm PCB li cas?" Qhov no yog cov lus nug uas siv tau vim tias qhov tuab ntawm tooj liab ntawm PCB muaj qhov cuam tshuam tseem ceeb rau nws txoj haujlwm thiab kev ua haujlwm tag nrho ua lub luag haujlwm tseem ceeb.Nyob rau hauv no blog ncej, peb yuav delve rau hauv lub ntsiab lus thiab muab koj nrog tag nrho cov tsim nyog cov ntsiab lus hais txog 1 oz tooj liab thickness ntawm PCB.

Ua ntej peb nkag mus rau hauv qhov tshwj xeeb, cia peb ua ib kauj ruam rov qab thiab nkag siab lub tswv yim ntawm qhov hnyav tooj liab ntawm PCB.Thaum peb tham txog qhov hnyav tooj liab, peb tab tom hais txog qhov tuab ntawm txheej tooj liab siv los ua PCB. Chav ntsuas ntawm qhov hnyav tooj liab yog ounces (oz). Nws yuav tsum raug sau tseg tias lub thickness ntawm tooj liab yog proportional rau nws qhov hnyav, uas yog, raws li qhov hnyav nce, lub thickness kuj yuav nce.

Tam sim no cia peb tsom mus rau 1 ooj tooj liab. Lo lus "1 ooj ntawm tooj liab" yog hais txog 1 ounce ib square feet ntawm tooj liab siv hauv kev tsim PCB.Cias muab, lub thickness ntawm 1 ooj ntawm tooj liab ntawm PCB yog kwv yees li 1.37 mils los yog 0.00137 ntiv tes, uas yog sib npaug rau 34.8 microns. Qhov kev ntsuas no yog tus qauv kev lag luam thiab siv ntau yam kev siv.

Lub thickness ntawm 1 ooj ntawm tooj liab ntawm PCB yog qhov zoo tagnrho rau ntau daim ntawv thov uas xav tau lub zog nruab nrab thiab cov teeb liab conductivity.Nws cuam tshuam qhov sib npaug zoo tshaj plaws ntawm kev ua tau zoo thiab kev siv nyiaj. Txawm li cas los xij, nws yuav tsum nco ntsoov tias cov ntawv thov sib txawv yuav xav tau qhov hnyav tooj liab sib txawv. Thaum 1 oz tooj liab muaj ntau yam, lwm yam kev xaiv xws li 2 oz lossis 0.5 oz tooj liab yuav zoo dua rau cov xwm txheej tshwj xeeb.

Tam sim no peb tau tham txog qhov tuab ntawm 1 ounce ntawm tooj liab, cia peb tshawb xyuas qee yam tseem ceeb uas txiav txim siab xaiv qhov hnyav ntawm tooj liab ntawm PCB.Ua ntej, nws nyob ntawm qhov xav tau ntawm lub zog ntawm lub voj voog. Yog hais tias lub Circuit Court yuav tsum tau nqa high tam sim no, ib tug thicker txheej ntawm tooj liab yuav tsum tau los xyuas kom meej txaus conductivity thiab tiv thaiv kom txhob muaj cua sov ntau dhau. Ntawm qhov tod tes, kev siv hluav taws xob qis dua tuaj yeem siv cov txheej tooj liab nyias.

Qhov thib ob, qhov zaus ntawm cov teeb liab nqa los ntawm PCB kuj cuam tshuam rau kev xaiv ntawm qhov hnyav tooj liab.Cov zaus ntau dua yuav tsum muaj cov txheej tooj liab tuab dua kom txo cov teeb liab poob thiab tswj cov teeb liab kev ncaj ncees. Qhov no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv high-speed digital circuits thiab xov tooj cua zaus siv.

Tsis tas li ntawd, cov neeg kho tshuab lub zog thiab nruj ntawm PCB raug cuam tshuam los ntawm qhov hnyav ntawm tooj liab.Thicker tooj liab txheej muab kev txhawb nqa zoo dua thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj thaum tuav, sib dhos thiab ua haujlwm.

Tag nrho cov nyob rau hauv tag nrho cov, lub thickness ntawm 1 ooj ntawm tooj liab ntawm ib tug PCB yog kwv yees li 1.37 mils los yog 0.00137 nti.Nws yog tus qauv ntsuas dav siv hauv kev lag luam rau ntau yam kev siv. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum xav txog cov kev cai tshwj xeeb ntawm PCB thiab qhov xwm txheej ntawm lub voj voog kom txiav txim siab qhov hnyav tshaj plaws tooj liab. Cov yam ntxwv xws li kev xav tau ntawm lub zog, lub teeb liab zaus, thiab lub zog txhua yam tuaj rau hauv kev ua si thaum txiav txim siab qhov no.

Hauv cov ntsiab lus, Paub txog qhov tuab ntawm 1 ooj tooj liab ntawm PCB yog qhov tseem ceeb rau txhua tus neeg koom nrog hauv kev lag luam PCB.Nws pab ua kom paub kev txiav txim siab txog kev tsim thiab kev tsim khoom, kom ntseeg tau tias kev ua haujlwm zoo ntawm lub voj voog. Yog li, lwm zaus ib tug neeg nug koj "Yuav ua li cas tuab yog 1 ooj ntawm tooj liab ntawm PCB?" koj muaj tag nrho cov kev paub uas koj xav tau los muab lawv cov lus teb raug.
