1oz Copper tuab npaum li cas?

Hauv kev lag luam luam tawm Circuit Board, txoj hauv kev tshaj plaws los qhia txog tooj liab tuab ntawm PCB yog nyob rau hauv ooj (oz). Vim li cas thiaj siv ib chav ntsuas qhov hnyav los qhia qhov tuab? Lus nug zoo! Yog hais tias 1oz (28.35 grams) ntawm tooj liab yog flattened kom tusyees npog 1 square feet ntawm qhov chaw (0.093 square meter), qhov tshwm sim thickness yuav yog 1.37mils (0.0348mm). Daim ntawv qhia kev hloov pauv rau cov ntsuas sib txawv tuaj yeem pom hauv qab no.

Kuv xav tau tooj liab ntau npaum li cas?

Los ntawm cov npoo dav, feem ntau PCBs yog tsim nrog 1oz tooj liab ntawm txhua txheej. Yog tias koj cov ntaub ntawv tsis suav nrog cov ntawv luam tawm lossis lwm yam tshwj xeeb, peb yuav xav tias 1oz ua tiav tooj liab hnyav ntawm txhua txheej tooj liab. Yog tias koj tus qauv tsim yuav tsum muaj qhov ntsuas hluav taws xob ntau dua, kev tiv thaiv, lossis impedance, cov tooj liab tuab yuav tsim nyog. Muaj ntau cov cuab yeej online uas tuaj yeem pab koj txiav txim siab seb qhov tuab, qhov dav lossis ntev npaum li cas koj cov kab yuav tsum tau ua kom ua tiav koj lub hom phiaj. Ob peb yam cuab yeej 3rd tog tau txuas hauv qab no. PCB Prime tsis koom nrog cov kws sau ntawv ntawm cov cuab yeej no.

 

Copper Distribution

Raws li txoj cai dav dav, tooj liab yuav tsum tau muab faib kom sib npaug li ntau tau thoob plaws hauv koj tus qauv tsim. Tsis tsuas yog hais txog tooj liab thickness ntawm txhua txheej, tab sis kuj yuav ua li cas nws faib thoob plaws txheej. Tau kawg, qhov no tsis yog ib txwm ua tau, tab sis khaws qhov no hauv siab thaum lub sijhawm teeb tsa.

Plating thiab etching yog cov txheej txheem organic hauv kev nkag siab tias tooj liab clad laminate yog submerged rau hauv ib lub vat ntawm cov tshuaj rau kev ua. Tsis muaj leej twg tswj tau qhov twg cov tooj liab raug tshem tawm los yog plated rau. Thaum lub sij hawm etch, cov duab npaj tau npog los tiv thaiv nws los ntawm etchant, tab sis cov tshuaj nyob rau hauv lub tank yaj cov tooj liab ntawm tus nqi sib txawv me ntsis nyob ntawm seb qhov twg cov yam ntxwv ntawm lub vaj huam sib luag, lub vaj huam sib luag tso rau hauv lub tank nws tus kheej, thiab qhov hnyav npaum li cas. los yog sparsely cov nta tooj liab raug faib.

Cov tshuaj tov nyob rau hauv lub plating thiab etching tank yog agitated thiab circulated thaum lub sij hawm ua kom txo tau cov inconsistencies; Txawm li cas los xij, lub vaj huam sib luag nrog ntau qhov sib txawv ntawm tooj liab tuaj yeem ua pov thawj teeb meem. Thaum lub sijhawm koj tsim, sim ua kom sib npaug ntawm koj cov tooj liab thoob plaws lub rooj tsavxwm es tsis muaj qhov qhib loj nrog cov yam ntxwv sib cais.

YUAV UA LI CAS YUAV TAU TXAIS PCB tooj liab THICKNESS

Xaiv qhov zoo tshaj plaws hnyav tooj liab thickness los siv rau lub plated los ntawm lub qhov (PTH) plays ib tug tseem ceeb yam tseem ceeb rau lub zuag qhia tag nrho kev cia siab ntawm lub luam Circuit Court board. Muaj ob lub ntsiab lus tseem ceeb los xav txog thaum txiav txim siab zoo PCB tooj liab tuab. Thawj yog lub peev xwm tam sim no ntawm lub thoob rau qhov tau txais cov cua sov tuaj. Qhov thib ob yog lub zog txhua yam txiav txim siab los ntawm tooj liab thickness, qhov loj thiab seb puas muaj kev txhawb nqa vias.

Cov neeg siv khoom feem ntau xav tsim PCBs nrog kev ua tau zoo ntawm tus nqi pheej yig. Thawj kauj ruam yog xaiv cov tooj liab uas haum rau koj hom PCB. Cov yam ntxwv tshwj xeeb ntawm cov tuab no yog qhov tseem ceeb hauv kev txiav txim siab ua haujlwm, kev ua haujlwm ntawm PCBs. Yog tias koj xav paub ntau ntxiv txog PCB tooj liab thickness xaiv los yog yuav ua li cas xaiv qhov zoo tshaj plaws haum koj tus qauv PCB, thov hu rau peb. Peb tsis tsuas yog muab cov lus qhia zoo xwb tab sis kev daws teeb meem tiav. Koj yuav tau txais cov PCB me me thiab ntse dua nrog kev ua tau zoo thiab kev ntseeg siab ntawm YMS.
