I-1. Khetha I-SCH noma i-PCB igama lefayela (ngesiNgisi nangamadijithi) bese ufaka igama lesandiso.
2. Umdwebo wesikimu uqala ukuklama ubukhulu begridi, ubukhulu bomdwebo, khetha uhlelo lwe-metric, engeza izinto ezinhle zelabhulali. Dweba imidwebo, izingxenye, nolayini ngokuya ngamamojula asebenzayo wesekethe ngendlela yokuthi kube lula ukubona umgomo. Ngokuya ngangokunokwenzeka iyunifomu, enhle, ungahambi ngocingo ngaphakathi kwengxenye, unake ukungahambi ngocingo phakathi kwephini, ngoba lokhu akulona uxhumano lukagesi. Kungcono ukungavumeli izingxenye ezimbili ziphine zixhumeke ngqo, ngemuva kokudweba kungabalwa ngokuzenzakalela (izidingo ezikhethekile ngaphandle), bese ufaka inani elihambisanayo lokuqamba, kungcono ukushintsha inani lokuqanjwa libe elibomvu, elinesibindi, ukuze kube kwehlukaniswe nelebuli. Ukube bekungcono ukubeka ilebuli kanye nenani lokuphakama endaweni efanelekile, okujwayelekile kwesobunxele ilebula, ilungelo liyinani eliqokiwe, noma ngaphezulu ilebula, alikho inani elingezansi ngezansi. Inqubo yokonga okwejwayelekile! Okokuqala, qiniseka ukuthi umdwebo wesikimu ulungile ngokuphelele, hlola i-ERC ukuthola iphutha, bese uphrinta isheke. Okwesibili, kungcono ukuthola umgomo wesifunda, kumandla aphezulu naphansi; Okwamanje okuncane; I-Analog, idijithali; Isiginali yesayizi; Usayizi wamandla emabhuloki wokuhleleka okulula ngemuva.
3. Umtapo wolwazi we-PCB womtapo wezincwadi ojwayelekile nendawo yawo yomtapo wolwazi ejwayelekile ayinakho ukukhiqizwa kokuhlanganiswa kwezinto, kufanele unake ukudweba ukubuka okuphezulu, unake usayizi, usayizi wephedi, isikhundla, inombolo, usayizi wembobo, isiqondisi, (indlela yokuphrinta usayizi omuhle ). Igama ngesiNgisi, okulula ukukubona okuhle kakhulu, kungcono ukukhombisa usayizi ohambisanayo, ukuze ngokuzayo ukuthola (kungasebenzisa igama nosayizi ohambelana nefomu letafula kugcine). Okwe-diode ejwayelekile, i-triode kufanele inake ukuvezwa kwelebula, kungcono ukuba nochungechunge olufanayo lwe-diode, iphakethe le-triode kulabhulali yabo, njenge-9011-9018, 1815, D880, njll. (I-LED), i-RAD0.1, i-Rb.1 /.2, nezinye izinto ezijwayelekile ezingekho kulabhulali ejwayelekile kufanele zifakwe kulabhulali yazo. Ejwayele ifomu lokumaka lezinto ezivamile (ama-resistors, ama-capacitors, ama-diode, ama-triode).

4. Khiqiza itafula lenethiwekhi kumdwebo wesikimu ngaphakathi kwephakeji yokwengeza, gcina, isheke le-ERC, ukhiqize isheke lohlu lwezinto. Khiqiza amatafula enethiwekhi.
5. Setha i-PCB, khetha uhlelo lwe-metric, bamba bese ubona ubukhulu begridi, yakhela ifreyimu yangaphandle ngokuya ngezidingo (khombisa noma udwebe wedwa), bese ufaka indawo yomgodi wokulungisa, ubukhulu ( Izikulufo ze-3.0mm zingasebenzisa iphedi lomgodi wangaphakathi elingu-3.5mm, izikulufo eziyi-2.5 zingasebenzisa imbobo yangaphakathi emi-3), onqenqemeni lwephedi, usayizi womgodi, indawo ehleliwe.
Faka imitapo yolwazi oyidingayo.
6. Ukuhlelwa kwetafula lenethiwekhi yokushaya, shayela ngezingxenye, shintsha ingxenye yosayizi wephedi, usethe imithetho yezintambo, ungashintsha ubukhulu belebuli, ukujiya, ufihle inani eliqokiwe. Bese ubeka futhi ukhiye izingxenye ezidinga izikhundla ezikhethekile kuqala. Ngemuva kwalokho ngokwesakhiwo semodyuli esebenzayo, (i-SCH ingasetshenziswa ekukhetheni kokushintshela ekukhetheni kwe-PCB), imvamisa ungasebenzisi i-X, Y ekubuyiseleni ingxenye, kepha ngokujikeleza kwesikhala, noma ukhiye we-L, (ngoba ezinye izinto azikwazi ibuyiselwe emuva, njengebhulokhi ehlanganisiwe, ukudluliswa, njll.). Okwimodyuli esebenzayo faka izinto zokuqala zesikhungo, noma izingxenye, bese ubeka ohlangothini lwezinto ezincane, (njengebhulokhi ehlanganisiwe ibekwa phambili, bese ufaka ibhulokhi eqondile futhi ehlanganisiwe izingxenye ezimbili ezixhunywe ngqo, faka nebhulokhi elihlanganisiwe iphini ixhunywe ngezinto, nezinto ezifanayo ndawonye, ​​ngokusemandleni amahle kakhulu futhi zifuna ukubheka ukusebenziseka ngemuva kokunamathiselwe). Vele, ezinye izinto ezikhethekile kufanele zibekwe kuqala, njengama-capacitors wokuhlunga nama-oscillator e-crystal kufanele abekwe eduze kwezinye izingxenye kuqala. Nezakhi eziphazamisa yonke le nto futhi ziqhelelanise nayo. Amamojula wamandla aphezulu futhi aphansi kufanele ahlukaniswe ngaphezu kuka-6.4mm. Naka indawo lapho kusetshenziswa khona usinki wokushisa, izixhumi nezilungisi. Gcwalisa kungasetshenziswa ezindaweni lapho kungenziwa khona izintambo. Futhi cabanga ukushabalalisa ukushisa, izinto ezishisayo.

Resistor kanye diode ukubekwa: ihlukaniswe enezingqimba futhi mpo:
1) Flat: lapho inani lezinto zesekethe lincane, nosayizi webhodi lesifunda likhulu, ngokuvamile kungcono ukusebenzisa iflethi; Okokumelana okungaphansi kwe-1 / 4W flat, ibanga phakathi kwamaphakethe amabili ngokuvamile liyi-4/10 inches, futhi ukumelana ne-1 / 2W flat, ibanga phakathi kwamaphakethe amabili ngokuvamile liyi-5/10 inches; Diode flat, 1N400X series rectifier, usually take 3/10 inch; 1N540X ochungechungeni wokulungisa kabusha ithubhu, imvamisa kuthatha ama-intshi angama-4 ~ 5/10.
2) mpo: lapho inani lezinto zesekethe lingaphezulu, nobukhulu bebhodi lesifunda bungebukhulu, ukusetshenziswa okujwayelekile kokuma mpo, mpo lapho ibanga phakathi kwamaphakethe amabili ngokuvamile lithatha i-1 kuye ku-2/10 inches.
7. Ukuxhuma izintambo: qala ngokusetha okuqukethwe emithethweni, amandla e-VCC, amandla we-GND neminye imigqa emikhulu yamanje ingasethwa iphuzu elibanzi (0.5mm-1.5mm), ngokuvamile i-1mm ingadlula i-1A yamanje. Isikhala esikhulu somugqa wamandla kagesi singasethelwa endaweni enkulu, imvamisa i-1mm ingu-1000V. Setha, indwangu yokuqala i-VCC, i-GND neminye imigqa ebalulekile. Qaphela umehluko phakathi kwamamojula. Kungcono ukwengeza eminye imigqa kuphaneli elilodwa. Izimbobo kungenzeka zingabi phezulu noma zibheke phezulu. Ngokuvamile, azikho izintambo phakathi kwama-solder pads wamabhulokhi ahlanganisiwe. Izintambo ezibanzi ezinomsinga ophakeme zingadonselwa kusendlalelo le-solder ukuze kufakwe i-tin ngemuva. Sebenzisa i-Angle degree engu-45 ukwenza izintambo.
8. Shintsha umugqa ngesandla: shintsha ububanzi bemigqa ethile, ikona, isichibi sezinyembezi noma iphedi yokushisela (kufanele kwenziwe ipaneli eyodwa), beka ithusi, ubhekane nocingo lomhlabathi.
9. Hlola i-DRC, i-EMC, njll., Bese ungaphrinta isheke, ukuqhathanisa ithebula lenethiwekhi. Ukuhlolwa kohlu lwezinto.
10. Faka imodeli (ngokuvamile esikrinini ku).
11. I-potentiometer ivamise ukuguqulwa ngokwewashi ukuze inyuke (i-voltage, yamanje, njll).
12. Imvamisa ephezulu (> 20MHz) ngokuvamile isisekelo semultipoint eminingi. <10MHz noma <1MHz iphoyinti elilodwa lokugxila. Phakathi nendawo kunendawo exubile.
13. Njengoba kudingeka, akuwona wonke amadivayisi okufanele afakwe emaphaketheni ajwayelekile, angahlanganiswa noma ashiselwe phezulu.
14. Lapho kuxhunywa izintambo ibhodi ephrintiwe, isikhundla sezingxenye ebhodini kufanele sinqunywe kuqala, bese kufanele kubekwe ucingo lwensimbi nolayini wamandla. Lapho uhlela izintambo zesiginali enejubane eliphezulu, kungcono ukubheka izintambo zesiginali enejubane eliphansi. Izikhundla zezingxenye zihlelwe ngokuya ngamandla kagesi, ukulingisa kwedijithali, isivinini, okwamanje nokunye. Ngaphansi kwezimo eziphephile, intambo kagesi kufanele isondele emhlabathini ngangokunokwenzeka. Ukunciphisa indawo yendandatho yemisebe eyehlukile kuyasiza ukunciphisa ukuphazamiseka kwesekethe. Lapho ama-logic circuits asheshayo, aphakathi naphakathi edinga ukubekwa ebhodini lesifunda, amasekethe wejubane eliphezulu kufanele abekwe eduze komphetho wesixhumi, futhi ama-logic wejubane eliphansi namasekethe wememori kufanele abekwe kude nesixhumi. Lokhu kunenzuzo ekwehliseni ukuhlangana kwe-impedance okuvamile, imisebe nokuphazamiseka. Ukwenza isisekelo kuyinto ebaluleke kakhulu. Cishe ngesikhathi sokuba nesipele, noma ezinye izinyathelo ezilula zokuphahlazeka, amafayela alimele ukwenza isipele.
