Yuav ua li cas nkag siab txog Circuit Board wiring daim duab? Ua ntej tshaj plaws, cia peb nkag siab txog cov yam ntxwv ntawm daim ntawv thov Circuit Court daim duab:
① Feem ntau ntawm daim ntawv thov circuits tsis kos daim duab hauv Circuit Court thaiv, uas tsis zoo rau kev lees paub ntawm daim duab kos duab, tshwj xeeb tshaj yog rau cov pib los soj ntsuam cov haujlwm hauv Circuit Court.
②Rau cov neeg pib tshiab, nws yog qhov nyuaj rau kev txheeb xyuas daim ntawv thov circuits ntawm kev sib xyaw ua ke dua li kev txheeb xyuas cov circuits ntawm cov khoom sib cais. Qhov no yog lub hauv paus chiv keeb ntawm tsis to taub lub internal circuits ntawm integrated circuits. Qhov tseeb, nws yog qhov zoo los nyeem daim duab lossis kho nws. Nws yog qhov yooj yim dua li cov khoom sib txuas sib txuas.
③Rau kev sib xyaw ua ke ntawm daim ntawv thov circuits, nws yooj yim dua los nyeem daim duab qhia thaum koj muaj kev nkag siab dav dav ntawm cov khoom siv hluav taws xob hauv kev sib txuas thiab kev ua haujlwm ntawm txhua tus pin. Qhov no yog vim tias tib hom kev sib xyaw ua ke muaj qhov tsis tu ncua. Tom qab paub txog lawv cov kev sib koom ua ke, nws yog ib qho yooj yim los soj ntsuam ntau qhov sib xyaw ua ke daim ntawv thov circuits nrog tib txoj haujlwm thiab ntau hom. Cov txheej txheem thiab kev ceev faj ntawm IC daim ntawv thov daim duab kos duab paub txog txoj hauv kev thiab kev ceev faj rau kev tsom xam ntawm kev sib xyaw ua ke feem ntau suav nrog cov ntsiab lus hauv qab no:
(1) Kev nkag siab txog kev ua haujlwm ntawm txhua tus pin yog tus yuam sij rau kev txheeb xyuas daim duab. Txhawm rau kom nkag siab txog kev ua haujlwm ntawm txhua tus pin, thov mus saib hauv phau ntawv qhia kev siv hluav taws xob sib xyaw ua ke. Tom qab paub txog kev ua haujlwm ntawm txhua tus pin, nws yog qhov yooj yim los soj ntsuam cov qauv kev ua haujlwm ntawm txhua tus pin thiab kev ua haujlwm ntawm cov khoom. Piv txwv li: Paub tias tus pin ① yog tus pin input, ces lub capacitor txuas nrog hauv koob nrog tus pin ① yog lub input coupling circuit, thiab Circuit Court txuas nrog tus pin ① yog lub input circuit.
(2) Peb txoj hauv kev kom nkag siab txog lub luag haujlwm ntawm txhua tus pin ntawm ib qho kev sib koom ua ke Muaj peb txoj hauv kev kom nkag siab lub luag haujlwm ntawm txhua tus pin ntawm ib qho kev sib txuas: ib qho yog los tham txog cov ntaub ntawv tseem ceeb; Lwm qhov yog los soj ntsuam cov duab hauv Circuit Court thaiv ntawm cov kev sib xyaw ua ke; Qhov thib peb yog los soj ntsuam daim ntawv thov Circuit Court ntawm kev sib xyaw ua ke Cov yam ntxwv ntawm txhua tus pin raug txheeb xyuas. Txoj kev thib peb yuav tsum muaj lub hauv paus kev txheeb xyuas Circuit Court zoo.
(3) Cov kauj ruam txheeb xyuas Circuit Court Integrated daim ntawv thov Circuit Court tsom xam cov kauj ruam yog raws li nram no:
① DC Circuit Court tsom xam. Cov kauj ruam no feem ntau yog txhawm rau txheeb xyuas qhov hluav taws xob sab nraum lub hwj chim thiab hauv av pins. Lus Cim: Thaum muaj ntau lub hwj huam mov pins, nws yuav tsum paub qhov txawv ntawm qhov kev sib raug zoo ntawm cov khoom siv fais fab, xws li seb nws puas yog lub hwj huam mov ntawm lub pre-theem thiab tom qab-theem circuit, los yog lub hwj chim mov pin ntawm sab laug. thiab txoj cai channel; rau ntau qhov av Cov pins kuj yuav tsum tau muab cais ua li no. Nws yog ib qho tseem ceeb rau kev kho kom paub qhov txawv ntau lub hwj chim pins thiab hauv av pins.
② Kev tsom xam kis tau tus mob. Cov kauj ruam no tsuas yog tsom mus rau sab nraud Circuit Court ntawm cov teeb liab input pins thiab cov zis pins. Thaum lub voj voog sib xyaw ua ke muaj ntau lub tswv yim thiab cov zis tawm pins, nws yog ib qho tsim nyog yuav tsum paub seb nws puas yog tus pin tso zis ntawm theem pem hauv ntej lossis hauv qab theem Circuit Court; rau lub dual-channel Circuit Court, paub qhov txawv cov tswv yim thiab cov zis pins ntawm sab laug thiab txoj cai.
③ Kev tshuaj xyuas cov kab hluav taws xob sab nraum lwm tus pins. Piv txwv li, txhawm rau txhawm rau paub qhov tsis zoo cov tswv yim pins, vibration damping pins, thiab lwm yam, kev tshuaj xyuas ntawm cov kauj ruam no yog qhov nyuaj tshaj plaws. Rau cov pib tshiab, nws yog ib qho tsim nyog yuav tsum tau cia siab rau cov ntaub ntawv ua haujlwm tus pin lossis cov duab hauv Circuit Court thaiv.
④ Tom qab muaj qee lub peev xwm ntawm kev lees paub cov duab, kawm los sau cov kev cai ntawm circuits sab nraum cov pins ntawm ntau yam kev ua haujlwm sib xyaw ua ke, thiab ua raws li txoj cai no, uas yog qhov tseem ceeb rau kev txhim kho qhov ceev ntawm kev paub cov duab. Piv txwv li, txoj cai ntawm sab nraud Circuit Court ntawm tus pin input yog: txuas mus rau qhov tso zis davhlau ya nyob twg ntawm lub yav dhau los Circuit Court los ntawm ib tug coupling capacitor los yog ib tug coupling Circuit Court; txoj cai ntawm sab nraud Circuit Court ntawm cov zis tus pin yog: txuas mus rau lub input davhlau ya nyob twg ntawm lub tom ntej Circuit Court los ntawm ib tug coupling Circuit Court.
⑤Thaum txheeb xyuas cov teeb liab amplification thiab kev ua cov txheej txheem ntawm kev sib txuas hauv Circuit Court, nws yog qhov zoo tshaj plaws los sab laj nrog cov duab thaiv hauv Circuit Court ntawm kev sib xyaw ua ke. Thaum txheeb xyuas cov duab thaiv hauv Circuit Court, koj tuaj yeem siv cov xub taw qhia hauv cov kab hluav taws xob xa mus kom paub seb lub voj voog twg lub teeb liab tau nthuav dav lossis ua tiav, thiab qhov kawg teeb liab yog tawm los ntawm tus pin twg.
⑥ Paub txog qee cov ntsiab lus tseem ceeb thiab tus pin DC voltage txoj cai ntawm kev sib txuas ua ke yog qhov tseem ceeb heev rau kev saib xyuas hauv Circuit Court. Lub DC voltage ntawm qhov tso zis ntawm OTL Circuit Court yog sib npaug rau ib nrab ntawm DC kev khiav hauj lwm voltage ntawm lub integrated circuit; DC voltage ntawm cov zis ntawm OCL Circuit Court yog sib npaug rau 0V; DC voltages ntawm ob qhov kawg tso tawm ntawm BTL Circuit Court yog sib npaug, thiab nws yog sib npaug rau ib nrab ntawm DC kev khiav hauj lwm voltage thaum powered los ntawm ib lub hwj chim mov. Lub sij hawm yog sib npaug rau 0V. Thaum lub resistor txuas ntawm ob tus pins ntawm ib qho kev sib txuas, tus resistor yuav cuam tshuam rau DC voltage ntawm ob tus pins no; Thaum ib lub kauj txuas ntawm ob tus pins, DC voltage ntawm ob tus pins sib npaug. Thaum lub sij hawm tsis sib npaug, lub kauj yuav tsum qhib; Thaum lub capacitor txuas ntawm ob tus pins lossis RC series Circuit Court, DC voltage ntawm ob tus pins yeej tsis sib npaug. Yog tias lawv sib npaug, lub capacitor tau tawg.
⑦ Raws li qhov xwm txheej ib txwm muaj, tsis txhob txheeb xyuas lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm cov khoom siv hluav taws xob hauv kev sib txuas, uas yog qhov nyuaj heev.
