Vim li cas thiaj muaj ntau dua thiab ntau tus pej xeem tau ua rau ntau - las txheej pob tw? Nov yog ib lo lus nug uas ntau tus phooj ywg muaj tam sim no. Tus editor qhia koj tias thaum PCB Circuit Coffic tau thawj zaug yug, lawv daim ntawv thov tsis loj. Lub sijhawm ntawd, tsis muaj ntau - txheej pob. Nrog rau kev loj hlob ntawm lub sijhawm, vim tias tau txais kev nce qib Circuit Court, cov ntim khoom siv hluav taws xob tau dhau los ua me thiab me dua. Yog li ntawd, qhov yuav tsum tau rau Circuit Cours nqa ntau cov hluav taws xob tau dhau los ua kev nce qib siab. Niaj hnub no, peb yuav coj koj los nkag siab txog qhov zoo ntawm multi- txheej pob laug:
Rau cov pcb tseem ceeb tshaj plaws, Cheebtsam muaj rau ntawm ib sab thiab cov xov hlau muaj cov tshuaj tiv thaiv sab nraud. Vim tias tsuas yog ib sab tuaj yeem tsim tawm, cov PCB no hu ua ob sab, yog li cov rooj zaum uas yog ob zaug, ua rau nws muaj kev haum rau ntau cov kev sib tw.
Rau cov khoom siv hluav taws xob zoo li hluav taws xob zoo li hluav taws xob, ib qho {{{0} {{{1} {{1} {Sided cov laug cam feem ntau yog txaus. Txawm li cas los xij, nrog cov kev txhim kho ntawm cov khoom hluav taws xob, qhov nyuaj ntawm cov hluav taws xob tau nce ntau dua, thiab cov qib siab yuav tsum tau muab tso rau pem hauv ntej rau kev ua haujlwm hluav taws xob ntawm PCBs. Yog hais tias ib -} {{5} - Cov laug cam tseem siv, lub ntim yuav loj, thiab cov hlau yuav nyuaj heev. Ntxiv mus, kev cuam tshuam ntawm hluav taws xob yog qhov nyuaj rau lis. Yog li mult - txheej pob zeb xwm txheej tawm.
Cov kev sib dhos ua kom ntev ntawm PCB multilayer cov laug cam yog siab. Loj me me; Kev sib txuas ntawm cov khoom siv hluav taws xob yog luv, uas ua kom nrawm nrawm kis ceev; Cov hlua hluav taws xob yooj yim; Rau siab - zaus circuences, ntxiv ib txheej av uas ua rau muaj kev cuam tshuam tsawg ntawm cov teeb liab thiab hauv av, ua rau muaj kev tiv thaiv zoo dua.
Cov kev siv hluav taws xob feem ntau tau siv cov txheej txheem ntau yog feem ntau plaub txheej lossis rau txheej txheej, tab sis tam sim no muaj tam sim no cov ntawv luam tawm Circuit Cours nrog 100 txheej.
