Dab tsi yog PCB Tooling qhov?
Tooling qhov ntawm PCB yog hais txog kev txiav txim siab txog qhov tshwj xeeb ntawm PCB los ntawm qhov hauv cov txheej txheem tsim PCB, uas yog ib qho tseem ceeb heev hauv cov txheej txheem tsim PCB.Kev ua haujlwm ntawm qhov chaw nrhiav qhov yog qhov ua tiav thaum lub rooj tsav xwm luam tawm tau ua.PCB tooling qhov positioning txoj kev ...Nyeem ntxiv -
Rov qab Drilling txheej txheem ntawm PCB
Qhov rov qab drilling yog dab tsi?Back drilling yog ib hom tshwj xeeb ntawm qhov tob qhov drilling.Hauv kev tsim cov txheej txheem ntau lawm, xws li 12-txheej boards, peb yuav tsum tau txuas thawj txheej rau cuaj txheej.Feem ntau, peb laum ib lub qhov (ib qho kev xyaum) thiab tom qab ntawd tso cov tooj liab.Ua li no, ...Nyeem ntxiv -
PCB Circuit Board Design Points
Puas yog PCB ua tiav thaum qhov kev teeb tsa tiav thiab tsis pom muaj teeb meem nrog kev sib txuas thiab sib nrug?Cov lus teb, tau kawg, tsis yog.Ntau tus pib, txawm tias suav nrog qee tus kws tshaj lij engineers, vim lub sijhawm txwv lossis tsis siab ntev lossis tsis ntseeg siab, nyiam nrawm, tsis quav ntsej ...Nyeem ntxiv -
Vim li cas Multilayer PCB Yog Cov Txheej Txheem?
PCB board muaj ib txheej, ob txheej thiab ntau txheej, uas tsis muaj kev txwv ntawm cov txheej txheem ntawm ntau txheej txheej.Tam sim no, muaj ntau tshaj 100 txheej ntawm PCB, thiab ntau txheej PCB yog plaub txheej thiab rau txheej.Yog li vim li cas tib neeg hais tias, "vim li cas PCB multilayers m ...Nyeem ntxiv -
Kub nce ntawm Printed Circuit Board
Qhov ncaj qha ua rau PCB kub nce yog vim muaj cov khoom siv hluav taws xob hluav taws xob dissipation, cov khoom siv hluav taws xob muaj qhov sib txawv ntawm cov hluav taws xob dissipation, thiab cov cua kub sib txawv nrog lub zog dissipation.2 phenomena ntawm kub nce nyob rau hauv PCB: (1) lub zos kub nce los yog ...Nyeem ntxiv -
