Dab tsi Kev Paub Yuav Tsum Tau Los Tsim Lub Rooj Tswjhwm Saib Circuit Court

Kev tsim ntawm lub rooj tsavxwm Circuit Court yuav tsum muaj ntau yam, xws li lub sijhawm xaim, vuam, qhov, kab routing thiab lwm yam teeb meem, tsim nyog layout ntawm lub rooj tsavxwm Circuit Court yuav tsum tau tsim raws li cov kev xav tau ntawm cov neeg siv khoom, cov khoom sib txawv daim ntawv thov thaj chaw rau pcb cov khoom yuav tsum tau. kuj txawv, tshooj no luv luv qhia txog plaub lub ntsiab lus uas yuav tsum tau paub txog kev tsim ntawm Circuit Board:

(1) Raws li ib txwm muaj, lub teeb liab cable dav yog 0.3mm(12mil), lub hwj chim cable dav yog 0.77mm(3{{10}}}mil) los yog 1.27mm (50mil); Qhov kev ncua deb ntawm cov xaim thiab xaim thiab nruab nrab ntawm cov xaim thiab lub ncoo yog ntau dua lossis sib npaug ntawm 0.33mm (13mil). Hauv kev siv tswv yim, yog tias muaj kev tso cai, qhov kev ncua deb yuav tsum raug txiav txim siab kom nce; Thaum lub ntho kheej yog qhov siab, ob lub xov hlau tuaj yeem siv tau ntawm cov xov hlau, qhov dav ntawm cov xov hlau yog 0.254mm (10mil), thiab cov xov ntawm cov xov hlau tsis tsawg tshaj 0.254mm (10mil). Nyob rau hauv cov xwm txheej tshwj xeeb, thaum tus pin ntawm lub cuab yeej yog ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntu tuaj yeem raug txo kom tsim nyog;

(2) Cov kev cai yooj yim ntawm PAD (PAD) thiab lub qhov hloov pauv (VIA) yog: txoj kab uas hla ntawm lub ncoo yog ntau dua 0.6mm dua li txoj kab uas hla ntawm lub qhov; Piv txwv li, universal pin-type resistors, capacitors thiab integrated circuits, thiab lwm yam, txais yuav disk / qhov loj 1.6mm /0.8mm (63mil / 32mil), qhov (socket), tus pin thiab diode 1N40{ {18}}7, thiab lwm yam., txais yuav 1.8mm / 1.{20}}mm (71mil / 39mil), hauv kev siv tswv yim, yuav tsum tau txiav txim siab raws li qhov tseeb ntawm qhov loj me, Yog tias muaj kev tso cai, tuaj yeem tsim nyog nce qhov loj ntawm lub ncoo; Lub mounting aperture ntawm cov khoom tsim los ntawm PCB pawg thawj coj saib yuav tsum yog li ntawm 0.2 ~ 0.4mm (8-16mil) loj dua qhov loj ntawm cov khoom siv pins;
(3) Los ntawm qhov (VIA) feem ntau 1.27mm/0.7mm(50mil/28mil); Thaum lub nthe ntom ntom yog qhov siab, lub qhov loj tuaj yeem raug txo qis, tab sis tsis yog txiav txim siab me, tuaj yeem txiav txim siab siv 1.} Hli / 0.6m (40mil / 24mil / 24mil);
(4) Sib nrug ntawm PAD, hlau thiab qhov PAD thiab VIA: Ntau dua lossis sib npaug rau 0.3mm(12mil) PAD thiab PAD: Ntau dua lossis sib npaug rau 0.3mm(12mil) ncoo thiab TRACK: Ntau dua lossis sib npaug rau 0.3mm(12mil) TRACK thiab TRACK: Ntau dua lossis sib npaug rau {{10}}.3mm(12mil) PAD thiab VIA: Ntau dua lossis sib npaug rau 0.254mm(10mil) PAD thiab PAD: Ntau dua lossis sib npaug rau 0.254mm(10}mil) PAD thiab TRACK: Ntau dua lossis sib npaug rau 0.254mm (10mil) TRACK thiab TRACK: Ntau dua los yog sib npaug rau 0.254mm (10mil) Taug qab thiab taug qab: Ntau dua lossis sib npaug rau 0.254mm (10mil)
