1. Sebenzisa indlela enhle yokubeka phansi (Umthombo: Inethiwekhi Yokushisekela Ngogesi)
Qinisekisa ukuthi umklamo unama-bypass capacitor anele kanye nezindiza eziphansi. Uma usebenzisa isifunda esihlanganisiwe, qiniseka ukuthi usebenzisa i-decoupling capacitor efanelekile eduze kwetheminali yamandla phansi (okungcono indiza ephansi). Umthamo ofanele we-capacitor uncike kuhlelo lokusebenza oluthile, ubuchwepheshe be-capacitor kanye nemvamisa yokusebenza. Lapho i-bypass capacitor ibekwa phakathi kwamandla nezikhonkwane zomhlabathi futhi ibekwe eduze nephinikhodi ye-IC efanele, ukuhambisana nozibuthe kagesi nokuba sengozini kwesekethe kungathuthukiswa.
2. Nikeza amaphakheji engxenye ebonakalayo
Phrinta ibhili lezinto zokwakha (bom) ukuze uhlole izingxenye ezibonakalayo. Izingxenye ezibonakalayo azinawo amaphakheji ahlobene futhi ngeke zidluliselwe esigabeni sesakhiwo. Dala ibhili lezinto zokwakha, bese ubuka zonke izingxenye ezibonakalayo ekwakhiweni. Izinto kuphela kufanele zibe amasignali amandla kanye nomhlabathi, ngoba zibhekwa njengezingxenye ezibonakalayo, ezicutshungulwa kuphela endaweni ye-schematic futhi ngeke zidluliselwe ekwakhiweni kwesakhiwo. Ngaphandle kwalapho isetshenziselwe izinjongo zokulingisa, izingxenye eziboniswa engxenyeni ebonakalayo kufanele zithathelwe indawo yizingxenye ezihlanganisiwe.
3. Qiniseka ukuthi unohlu oluphelele lwedatha
Hlola ukuthi ingabe ikhona yini idatha eyanele embikweni webhili yezinto zokwakha. Ngemva kokudala umbiko webhili yempahla, kuyadingeka ukuhlola ngokucophelela futhi ugcwalise idivayisi engaphelele, umphakeli noma ulwazi lomkhiqizi kukho konke okufakiwe kwezingxenye.
4. Hlunga ngokwelebula yengxenye
Ukuze kube lula ukuhlungwa nokubonwa kwebhili yezinto zokwakha, qiniseka ukuthi izinombolo zezingxenye zinezinombolo ezilandelanayo.
5. Hlola isekethe yesango eleqile
Ngokuvamile, okokufaka kwawo wonke amasango angasasebenzi kufanele kube noxhumo lwesignali ukuze kugwenywe ukuntanta amatheminali okokufaka. Qiniseka ukuthi uhlole wonke amasekhethi esango angasasebenzi noma angekho, futhi konke okokufaka okungasebenzisi zintambo kuxhumeke ngokuphelele. Kwezinye izimo, uma itheminali yokufaka imisiwe, lonke uhlelo alukwazi ukusebenza ngendlela efanele. Thatha i-dual op amp evame ukusetshenziswa ekwakhiweni. Uma kusetshenziswa eyodwa kuphela yama-op amp ezingxenyeni ezikabili op amp IC, kuyanconywa ukuthi usebenzise enye i-op amp, noma ugxilise okokufaka kwe-op amp engasetshenzisiwe, futhi kusetshenziswe inzuzo yobunye efanelekile (noma enye inzuzo) ) Inethiwekhi yempendulo yokuqinisekisa ukuthi yonke ingxenye ingasebenza ngokujwayelekile.
Kwezinye izimo, ama-IC anamaphini antantayo angase angasebenzi kahle ngaphakathi kwebanga lokucaciswa. Ngokuvamile kuphela uma idivayisi ye-IC noma amanye amasango kudivayisi efanayo engasebenzi esimweni sokugcwala-uma okokufaka noma okukhiphayo kuseduze noma kumzila wamandla wengxenye, le IC ingahlangabezana nokucaciswa lapho isebenza. Ukulingisa ngokuvamile akukwazi ukuthwebula lesi simo, ngenxa yokuthi imodeli yokulingisa ngokuvamile ayixhumi izingxenye eziningi ze-IC ndawonye ukuze imodeli yomphumela wokuxhuma ontantayo.
6. Cabangela ukukhetha kwengxenye yokupakisha
Kuso sonke isigaba somdwebo wohlelo, izinqumo zengxenye yokupakishwa kanye nephethini yomhlaba okudingeka zenziwe esigabeni sokuhlela kufanele zicatshangelwe. Nazi ezinye iziphakamiso okufanele uzicabangele lapho ukhetha izingxenye ezisuselwe ekufakweni kwengxenye.
Khumbula, iphakheji ihlanganisa ukuxhunywa kwephedi kagesi kanye nobukhulu bemishini (x, y, no-z) bengxenye, okungukuthi, umumo wengxenye yomzimba namaphinikhodi axhumeka ku-PCB. Lapho ukhetha izingxenye, udinga ukucabangela noma yimiphi imikhawulo yokukhweza noma yokupakisha okungenzeka ibe khona ezingqimbeni ezingaphezulu neziphansi ze-PCB yokugcina. Ezinye izingxenye (njengama-polar capacitor) zingase zibe nemikhawulo ephezulu ye-headroom, edinga ukucatshangelwa kunqubo yokukhetha ingxenye. Ekuqaleni komklamo, ungaqala ukudweba uhlaka oluyisisekelo lwebhodi lesifunda, bese ubeka izingxenye ezinkulu noma ezibucayi (njengezixhumi) ohlela ukuzisebenzisa. Ngale ndlela, umbono we-virtual view webhodi lesifunda (ngaphandle kwezintambo) ungabonakala ngendlela enembile futhi ngokushesha, futhi ukuma okuhlobene nokuphakama kwengxenye yebhodi lesifunda kanye nezingxenye kunganikezwa ngokunembile. Lokhu kuzosiza ekuqinisekiseni ukuthi izingxenye zingafakwa ngokufanele emaphaketheni angaphandle (imikhiqizo yepulasitiki, i-chassis, i-chassis, njll.) ngemva kokuba i-PCB isiqoqwe. Shayela imodi yokubuka kuqala ye-3D kusukela kumenyu yamathuluzi ukuze uphequlule lonke ibhodi lesekethe
