1. Sebenzisa indlela enhle yesisekelo (umthombo: Inethiwekhi Yentshiseko Ye-elekthronikhi)

Qinisekisa ukuthi ukwakheka kunama-capacitors anele afanayo kanye nezindiza zomhlaba. Lapho usebenzisa umjikelezo ohlanganisiwe, qiniseka ukusebenzisa i-capacitor efanelekayo yokukhohlisa eduze kwe-poer terminal emhlabathini (mhlawumbe indiza emhlabathini). Amandla afanele eCapacitor ancike kwisicelo esithile, ubuchwepheshe beCapacitor kanye nemvamisa yokusebenza. Lapho i-Pass Capacitor ibekwe phakathi kwamakhoneni kagesi nezikhonkwane zomhlaba futhi ibekwe eduze kwe-IC PIN efanele, ukuhambisana kwe-electromagnetic kanye nokususwa kwesifunda kungalungiselelwe.

Phrinta umthethosivivinywa wezinto zokwakha (BOM) ukubheka izingxenye ezibonakalayo. Izakhi ezibonakalayo azinakupakishwa okuhambisana nakho futhi ngeke zidluliselwe esiteji sokuhlelwa. Dala uMthethosivivinywa Wezinto zokwakha, bese ubuka zonke izinto ezibonakalayo ekwakhiweni. Ukuphela kwezinto kufanele kube amasiginali anamandla nezimpawu zomhlaba, ngoba zithathwa njengezinto ezibonakalayo, ezicutshungulwa kuphela kwimvelo ye-schematic futhi ngeke zidluliselwe ekwakhiweni kwesakhiwo. Ngaphandle kokuthi isetshenziselwe izinhloso zokulingisa, izakhi eziboniswe engxenyeni ebonakalayo kufanele zithathelwe indawo ngezakhi ezihlanganisiwe.

3. Qiniseka ukuthi unedatha ephelele yohlu lwezinto ezibonakalayo

Bheka ukuthi ngabe kukhona idatha eyanele kuMbiko Wokubika Kwezinto zokwenziwa. Ngemuva kokudala uMthethosivivinywa Wezinto Zokwenziwa Kwezinto zokwenziwa, kuyadingeka ukuhlola ngokucophelela futhi uqedele idivaysi engaphelele, umhlinzeki noma imininingwane yomenzi kuzo zonke izinto ezifakiwe.

4. Hlunga ngokuya ngelebula lengxenye

Ukwenza lula ukuhlunga nokubuka kwenkokhelo yezinto zokwakha, qiniseka ukuthi izinombolo zezakhi zibaliwe.

I-5. Bheka umjikelezo wesango owedlulele

Ngokuvamile, okokufaka kwawo wonke amasango angenakuphinde kufanele kube nokuxhumeka kwesiginali ukuze ugweme ukuntanta ama-terminals wokufaka. Qiniseka ukuthi ubheke yonke imibuthano yesango engafuneki noma engekho, futhi konke okokufaka okungafundile kuxhunyiwe ngokuphelele. Kwezinye izimo, uma i-terminal yokufaka imisiwe, lonke uhlelo alukwazi ukusebenza kahle. Thatha i-amp e-dual op amp evame ukusetshenziswa ekwakhiweni. Ukube nje enye yama-amps e-OP Amps isetshenziswa ezingxenyeni ezimbili ze-OP AMP IC, kunconywa ukuthi usebenzise enye i-OP AMP, noma inhlabathi yokufaka kwe-OP AMP engasetshenziswanga, bese ufaka inzuzo efanelekile (noma enye inzuzo)) Inethiwekhi yempendulo ingasebenza ngokujwayelekile.

Kwezinye izimo, ama-ICS anezikhonkwane ezintantayo angeke asebenze kahle ngaphakathi kwebanga lokucaciswa. Imvamisa kuphela lapho idivaysi ye-IC noma amanye amasango kudivayisi efanayo ayisebenzi ngesimo esigcwele - lapho okufakwayo noma okuphumayo kuseduze noma kujantshi lwamandla engxenyeni, le nto ingahlangabezana nokucaciswa lapho isebenza. Ukulingisa kungakwazi ukuthwebula lesi simo, ngoba imodeli yokulingisa ngokuvamile ayixhumeki izingxenye eziningi ze-IC ndawonye ukuze ilingise imiphumela yokuxhuma esintantayo.

6. Cabanga ngokukhethwa kokupakishwa kwengxenye

Kuwo wonke umdwebo we-Schematic umdwebo, ukufakwa kwengxenye yezakhi nezinqumo zephethini lomhlaba okudingeka kwenziwe esigabeni sezakhiwo kufanele kubhekwe. Nawa ezinye iziphakamiso okufanele uzicabangele lapho ukhetha izakhi ezisuselwa ekuphangethweni kwengxenye.

Khumbula, iphakethe lifaka phakathi ukuxhumeka kwe-serlecal Pad kanye nobukhulu bemishini (x, y, no-z) yengxenye, okungukuthi, ukwakheka komzimba kwengxenye nezikhonkwane ezixhumeka kwi-PCB. Lapho ukhetha izakhi, udinga ukucubungula noma yimiphi imikhawulo yokukhwela noma yokupaka okungenzeka ikhona phezulu nangaphansi izingqimba ze-PCB yokugcina. Ezinye izakhi (njengama-capacitors e-polar) zingaba nemikhawulo ephezulu yekhanda, okudingeka kubhekwe kwinqubo yokukhetha ingxenye yengxenye. Ekuqaleni kokwakheka, ungaqala ukudweba i-Basic Bood Frame Shape, bese ubeka ezinye izinto ezinkulu noma ezibucayi (ezinjengezixhumi) ohlela ukuzisebenzisa. Ngale ndlela, umbono obonakalayo webhodi yokujikeleza (ngaphandle kwentambo) ungabonakala ngendlela enembile futhi ngokushesha, futhi ukuphakama okuhlobene nokuphakama kwengxenye ye-Contenced nengxenye ye-Contenent ye-Computer kanye nezakhi kunganikezwa zinembile. Lokhu kuzosiza ekuqinisekiseni ukuthi izakhi zingafakwa kahle ekuphangalaleni kwangaphandle (imikhiqizo yepulasitiki, i-chassis, chassis, njll.) Ngemuva kokuthi iPCB ihlanganiswe. Shayela imodi yokubuka kuqala ye-3D kusuka kumenyu yamathuluzi ukuze udlulise amehlo kulo lonke ibhodi yesekethe
