Daim ntawv thov ntawmtuab cig circuit Coffic BoardRouting cov neeg tawm tsam yog feem ntau xav hauv cov hauv qab no:
Kev tiv thaiv kev tiv thaiv thiab kev ua kom zoo
Cov mis rau xam cov hlau tsis kam yog: r=p × cheeb tsam
R=p × cheeb tsam
Ntawm lawv, qhov tsis kam ntawm tooj liab ntawm 25℃yog 1.724. Los ntawm kev kho cov hlau dav thiab tuab (xws li 0.03mm rau 1oz tooj liab thickness), lub peev xwm tsis kam ntawm qhov ntev tau muab xam. Piv txwv li, thaum lub tuab ntawm lub tooj liab txheej yog 1oz, cov hlau dav yog 1 hli, thiab qhov ntev yog 10cm, qhov tsis kam yog kwv yees li 0.05 ω.
Tam sim no nqa tau muaj peev xwm thiab tswj hwm
Tuab cov pob txha circuit tseem txo qis kev tiv taus kev tiv thaiv thiab kev nce nqi ntawm tooj liab ntawv ci (feem ntau tshaj li 35 μ m). Piv txwv li, nyob rau hauv high - zaus puag ncig hluav taws xob tsim, kev tsis sib haum xeeb yuav ua rau lub teeb liab kev ua kom pom. Los ntawm kev ua kom zoo dua cov hlau dav (pom zoo ntau dua lossis sib npaug nrog 10cm), tsawg dua los yog sib npaug ntawm 10cm), tsawg dua lossis sib npaug lossis sib luag ntawm cov kev hloov pauv tuaj yeem tswj tau zoo.
Cov Ntawv Thov Kev Pab Cuam tiag tiag
Sampling Resistor: Hauv lub zog hluav taws xob, ib qho ntsuas hluav taws xob, 0.05 ω piv txwv resistor tuaj yeem tsim kho cov kev ntsuas kom raug rau cov kev hloov pauv me me.
Kev kub ceev teeb liab kis tus kis: nyob rau hauv high - zaus circuits tuaj yeem zam cov cim kev xav thiab kev caij tsheb ciav hlau, kom cov ntaub ntawv kev ruaj ntseg.
Cov cuab yeej siv tam sim no: tuab cov kab ke tooj liab nrog cov qauv hluav taws xob muaj zog tuaj yeem nqa qhov ceev dua tam sim no, txo cov cua kub thiab tsis kam poob.
