Ekuhlanganisweni kwethusi, ukuze kuzuzwe umphumela oyifunayo wokufakwa kwethusi, sidinga ukunaka lezo zinkinga: 1. Uma kunezizathu eziningi ku-PCB, njenge-SGND, AGND, GND, njll., ngokuya ngezikhundla ezihlukene zendawo ye-PCB, "umhlabathi" obaluleke kakhulu usetshenziswa njengenkomba yokumboza ngokuzimela ithusi, umhlabathi wedijithali. kanye nomhlabathi we-analog.Akukho okuningi ongakusho mayelana ne-copper coating ngokwehlukana.Ngesikhathi esifanayo, ngaphambi kokugqoka kwethusi, imigqa yokuhlinzeka amandla ehambisanayo iqala ukuqiniswa: 5.0V, 3.3V, njll.

2. Ukuze uthole uxhumano lwephuzu elilodwa lezizathu ezahlukene, indlela yokuxhuma ngo-0 ohm ukumelana noma ubuhlalu kazibuthe noma inductance. 3. I-Copper cladding eduze ne-crystal oscillator.I-crystal oscillator kumjikelezo iwumthombo wokuphuma kwemvamisa ephezulu.Indlela yokufaka ithusi ezungeze i-crystal oscillator, bese ugaya igobolondo le-crystal oscillator ngokuhlukana. 4. Inkinga yesiqhingi (indawo efile), uma ucabanga ukuthi sikhulu kakhulu, ngeke kubize imali eningi ukuchaza umhlabathi bese uyengeza. 5. Ekuqaleni kwe-wiring, ucingo oluphansi kufanele luphathwe ngokulinganayo, futhi ucingo oluphansi kufanele luhanjiswe kahle lapho luhamba.Awukwazi ukuthembela ekwengezweni kwe-vias ngemuva kokumbozwa ngethusi ukuze uqede iphinikhodi eliphansi ukuze uxhumeke.Lo mphumela mubi kakhulu. 6. Kungcono ukuthi ungabi namakhona abukhali ebhodini ( 7. Ungathululi ithusi endaweni evulekile ye-wiring engxenyeni ephakathi yebhodi le-multi-layer.Ngoba kunzima kakhulu kuwe ukwenza leli thusi lithele "umhlabathi omuhle". 8. Izinsimbi ngaphakathi kwedivayisi, njengamasinki okushisa ensimbi, imigoqo yokuqinisa insimbi, njll., kumele "zisekelwe kahle". 9. Ibhulokhi yensimbi yokukhipha ukushisa ye-voltage stabilizer eneziphetho ezintathu kufanele ibe nesisekelo esihle.Ibhande lokuhlukanisa phansi eliseduze ne-crystal oscillator kufanele libe nesisekelo esihle.Ngamafuphi nje: uma ukugqokwa kwethusi ku-PCB kusetshenzwa kahle, kuzoba "izinzuzo ezingaphezu kobubi".Inganciphisa indawo ebuyayo yomugqa wesiginali futhi inciphise ukuphazanyiswa kwe-electromagnetic yesiginali ngaphandle.
