(1) Nws yog qhov zoo tshaj plaws los tso rau cov cheeb tsam ntawm ib sab. Yog tias ob npaug {{{2} ated uted tso cov khoom siv yog qhov yuav tsum tau ua, cov pin hom yuav tsum muab tso rau hauv qab txheej, thiab nws yog qhov zoo tshaj plaws los tso cov khoom sib txuas ntawm ib sab. Nws yog tau tias lub tshav pob hluav taws xob yuav nyuaj rau qhov chaw thiab tsis muaj txiaj ntsig zoo rau cov txheej txheem saum npoo av ntawm cov txheej txheem ntawm cov duab duab kos duab PCB. Thaum muab tso rau ntawm ib sab, tsuas yog ib txheej lo lo ntxhuav yuav tsum tau siv rau ntawm ib sab ntawm Circuit Court Board kom txo cov nqi.
(2) kev npaj txoj hauj lwm thiab kev coj ntawm interface Cheebtsam. Feem ntau hais lus, raws li kev sib txuas ntawm cov Circuit Court Board thiab cov khoom sab nraud (hluav taws xob sib txuas), nws feem ntau yog npaj rau ntawm ntug kev Circuit Court, xws li cov chaw nres nkoj ntawm cov Circuit Court, xws li cov chaw nres nkoj ntawm cov kab ke. Yog tias muab tso rau hauv qhov chaw nruab nrab ntawm Circuit Court Board, nws yog qhov tseeb tsis muaj txiaj ntsig rau kev xaim hluav taws xob. Cov khoom sib txuas yog feem ntau tau npaj rau ntawm cov npoo ntawm Circuit Courner Board, xws li cov chaw nres nkoj serial thiab sib piv. Nws tseem ua tau tias kev sib txuas tsis tuaj yeem tsim vim muaj kev thaiv ntawm lwm cov khoom. Tsis tas li ntawd, thaum tso lub interface, them nyiaj rau cov kev taw qhia ntawm lub interface kom cov xov hlau txuas tau. Thaum muab lub interface, ua tib zoo mloog rau cov kev taw qhia ntawm lub interface thiab ntseeg tau tias nws yog qhov zoo coj tawm thiab deb ntawm cov Circuit Court Board. Txoj kev coj ncaj qha thiab khaws cia kom deb ntawm cov boardcuit Court board. Tom qab lub interface yog muab tso rau, hom ntawm interface yuav tsum tau qhia meej meej tias siv txoj hlua ntawm lub interface tivthaiv; Rau lub hwj chim cuam tshuam, qhov ntsuas hluav taws xob yuav tsum tau qhia kom tsis txhob muaj kev cuam tshuam nrog kev cuam tshuam nrog cov hluav taws xob hauv cov hluav taws xob. Rau lub hwj chim cuam tshuam, qhov ntsuas hluav taws xob yuav tsum tau qhia kom tsis txhob muaj kev cuam tshuam nrog kev cuam tshuam nrog cov hluav taws xob hauv cov hluav taws xob.
(3) Nws yog qhov zoo tshaj plaws kom muaj hluav taws xob cais daim ntaub ntawm siab- voltage cov cheebtsam thiab qis {voltage Cheebtsam. Uas yog hais, nws yog qhov zoo tshaj plaws kom muaj hluav taws xob cais daim ntaub ntawm siab {{{- voltage cov cheebtsam, yog li kom tsis txhob muaj qhov sib txawv ntawm cov qib voltage ntau. Tsis txhob muab cov khoom sib txuas nrog cov qib voltage ntau ua ke. Cov Cheebtsam Sib Koom Ua ke tau txais txiaj ntsig hluav taws xob, kev sib cais hluav taws xob, thiab anti {8}- kev cuam tshuam
(4) Nws yog qhov zoo tshaj plaws los tso cov khoom sib txuas nrog kev sib txuas hluav taws xob sib txuas ua ke. Nov yog lub tswvyim modular. ) Nws yog qhov zoo tshaj plaws los tso cov khoom sib txuas nrog kev sib txuas hluav taws xob ua ke. Nov yog lub tswvyim modular.
(5) rau cov khoom sib xyaw uas nquag ua suab nrov, xws li xov ntau li crystal oscillators, lawv yuav tsum tso ntau li ntau tau. Rau cov khoom sib xyaw uas nquag ua suab nrov, xws li cov xov dav thiab siab} cov twj siv hluav taws xob xws li cov khoom siv crystal, lawv lub moos tawm tswv yim lub chaw tsim nyog yuav tsum muab tso rau. Cov voj voog siab tam sim no thiab hloov hluav taws xob kuj tseem pheej nrov thiab muab tso rau ntawm lub moos tawm tswv yim ntawm CPU. Cov voj voog siab tam sim no thiab cov hluav taws xob hloov pauv, yog li cov khoom siv nrawm nrawm nrawm xws li cov teeb liab ceev teeb tsa zoo li cov logic tswj cov voj voog thiab khaws cov voj voog. Yog tias ua tau, nws raug nquahu kom siv cov tswj hwm tswj tau nrog lub zog hluav taws xob los sib cuam tshuam nrog kev cuam tshuam nrog kev ntseeg tau ntawm Circuit Court.
(6) Sim tso cov decoupling capacitors thiab lim capacitors ncig lub zog thiab nti. Kev npaj ntawm decoupling capacitors thiab lim capacitors yog txhawm rau txhim kho Circuit Court Board qhov kev ua haujlwm hluav taws xob. Decoupling capacitors thiab lim capacitors yuav tsum muab tso rau ib ncig ntawm lub zog muab thiab nti kom ntau li ntau tau. Qhov chaw zoo yog qhov tseem ceeb ntsuas los txhim kho -} sib cuam tshuam. Hauv kev siv cov kev siv, cov kev sib txuas, thiab xaim ntawm cov ntawv luam tawm hluav taws xob tuaj yeem ua rau muaj kev kub ntxhov, ua rau muaj kev kub ntxhov thiab ntau zaus hauv cov hluav taws xob. Tso lawv ntawm lub hwj chim muab thiab av kuj tseem tuaj yeem ua rau muaj kev tsis tseem ceeb ntawm cov phiaj xwm kev ua haujlwm tseem ceeb, ua rau muaj kev kub thiab ntau zaus hauv cov hluav taws xob. Ib qho 0.1 f decoupling capacitor tuaj yeem siv tau zoo lim tawm cov siab - zaus Ripples thiab spikes. Yog tias cov capinctor accitor siv rau ntawm Circuit Courruit Board, nws yuav tsum muab tso rau ze rau lub zog pin ntawm cov khoom siv. Muab qhov chaw tso rau saum npoo av capacitor ze rau lub hwj huam pin ntawm cov khoom siv. Rau lub zog hloov dua siab tshiab lossis cov tswv yim hluav taws xob tawm los yog zoo tshaj plaws rau nruab ib qho kev ntsuas 10 f lossis loj dua capacitor ntxiv ntxiv txhim kho lub zog zoo.
(7) Cov lej ntawm cov khoom siv yuav tsum tau npaj ze rau ntawm cov kab sib xyaw, nrog cov khoom sib xyaw, kev coj ua, thiab tsis sib piv nrog cov cheebtsam, vias, thiab cov ntaub qhwv. Kev txheeb xyuas ntawm cov khoom siv yuav tsum tau npaj ze rau cov ncej ntawm cov khoom sib xyaw, nrog cov khaub ncaws sib xyaw, kev coj ua zoo, thiab nyiag. Thawj tus pin ntawm cov khoom sib txuas lossis txuas qhia qhia cov kev taw qhia; Cov cim zoo thiab tsis zoo yuav tsum tau cim kom pom tseeb ntawm PCB thiab tsis pub them rau; Cov khoom siv fais fab hluav taws xob (xws li hloov dua siab tshiab, thiab hloov cov khoom siv hluav taws xob tsis txaus, thiab hloov cov chaw muaj peev xwm sib xyaw ntawm lawv ib sab. Tawm ntawm qhov chaw welding txaus rau ntawm periphery, thiab lwm yam.
