Muaj ntau yam kev paub thiab kev paub txog kev kho vajtse hauv Is Taws Nem uas yooj yim heev.Zoo li lub teeb liab kev ncaj ncees, EMI, PS tsim yuav ua rau koj tsis meej pem.Tsis txhob maj nrawm, siv koj lub sijhawm nrog txhua yam.
Kab lus no tau mob siab rau cov neeg uas nyuam qhuav pib lossis tab tom pib tsim kho vajtse circuits, yog li koj tuaj yeem taug kev tsawg dua "deours" hauv "hardware circuit design".
1. Cov tswv yim dav dav
Tsim cov khoom siv hluav taws xob, lub hauv paus loj thiab cov qauv tsim kom pom, tab sis ua qhov no tsis yooj yim heev.Qee lub ntsiab lus loj yuav yog lawv cov thawj coj, cov kws qhia ntawv tau xav, lawv tsuas yog qhov tshwj xeeb ntawm kev siv lub tswv yim;tab sis kuj muaj qee tus tsim lawv tus kheej lub moj khaum, nws yog ib qho tsim nyog los txiav txim siab seb lub luag haujlwm ua tiav, thiab tom qab ntawd nrhiav seb puas muaj peev xwm ua tiav cov haujlwm zoo ib yam lossis zoo sib xws ntawm pawg thawj coj saib (kom paub siv cov txiaj ntsig ntawm lwm tus kom ntau li ntau tau. , cov kws tshaj lij engineers yuav paub yuav kawm li cas los ntawm cov txiaj ntsig ntawm lwm tus).
2. Nkag siab txog Circuit Court
Yog tias koj pom cov qauv siv, ces ua kev zoo siab, koj tuaj yeem txuag tau ntau lub sijhawm (nrog rau kev tsim ua ntej thiab tom qab kev debugging).Tam sim ntawd luam?TSIS TAU, los yog nyeem thiab nkag siab ua ntej, ntawm ib sab, tuaj yeem txhim kho peb txoj kev nkag siab ntawm Circuit Court, thiab tuaj yeem zam qhov yuam kev hauv kev tsim.
3. Puas tsis pom tus qauv siv?
Ua ntej txiav txim siab loj IC nti, nrhiav cov ntaub ntawv, saib seb nws qhov tseem ceeb tsis tau raws li lawv tus kheej xav tau, uas yog qhov tseem ceeb tsis lawv xav tau, thiab seb lawv puas tuaj yeem nyeem cov ntsiab lus tseem ceeb no, yog lub cim ntawm lub peev xwm ntawm tus kws kho vajtse, uas kuj yog. yuav tsum tau khaws cia maj mam dhau sijhawm.Thaum lub sijhawm no, ua tib zoo nug cov lus nug, vim tias qhov koj tsis nkag siab, lwm tus tuaj yeem yog lo lus los tsa koj, tshwj xeeb tshaj yog hauv kev tsim kho vajtse.
4. Peb lub ntsiab tsim ntawm cov khoom siv hluav taws xob
Schematic, PCB, daim nqi ntawm cov ntaub ntawv (BOM) rooj.
Schematic tsim yog los txhais cov tswv yim yav dhau los rau hauv Circuit Court schematic.Nws zoo ib yam li peb phau ntawv nyeem daim duab kos duab.PCB suav nrog lub rooj tsavxwm tiag tiag, uas yog raws li daim duab kos duab rau hauv daim ntawv teev npe (netlist yog tus choj ntawm daim duab kos duab thiab PCB), thiab cov khoom tshwj xeeb ntawm pob muab tso rau ntawm lub rooj tsavxwm, thiab tom qab ntawd raws li cov khoom siv. ya xov hlau (tseem hu ua pre-rub xov hlau) los txuas nws cov hluav taws xob teeb liab (xaiv).Tom qab ua tiav ntawm PCB layout thaiv, cov khoom siv twg yuav tsum tau sau tseg, yog li peb yuav siv BOM rooj.
5. Cov cuab yeej siv dab tsi?
Prote, tseem hu ua altimuml yooj yim pib, kuj nrov dua nyob rau hauv Suav teb, los tiv thaiv kev ua haujlwm dav dav tau txaus rau qhov pib ntawm tus tsim qauv siv.
Qhov tseeb, tsis muaj teeb meem nrog cov cuab yeej yooj yim protel lossis cov cuab yeej cadence nyuaj, kho vajtse tsim yog tib yam (protel kev ua haujlwm zoo ib yam li windwos, yog hom lus txib tom qab; thiab cadence khoom tswvyim & allegro yog hom lus txib ua ntej, siv rau protel, mam li hloov mus rau cov cuab yeej cadence, kev siv protel, thiab kev siv cov cuab yeej cadence, kev siv cov protel, kev siv cov cuab yeej cadence, kev siv cadence, kev siv cov cuab yeej cadence, kev siv cov cuab yeej cadence, siv cov cuab yeej cadence, Kev siv cov cuab yeej cadence dheev hloov mus rau cov cuab yeej cadence, yuav tsis siv rau qhov no).
