Kwi-copper cladding, ukuze kuphunyezwe umphumo ofunekayo wokugquma ubhedu, kufuneka sinikele ingqalelo kule miba: 1. Ukuba kukho izizathu ezininzi kwi-PCB, njenge-SGND, AGND, GND, njl., ngokwezikhundla ezahlukeneyo ze-PCB, owona mhlaba ubaluleke kakhulu usetyenziswa njengesalathiso sokugubungela ngokuzimeleyo ubhedu, umhlaba wedijithali. kunye nomhlaba we-analog.Akukho nto ingako yokuthetha malunga nokugquma ubhedu ngokwahlukileyo.Ngexesha elifanayo, ngaphambi kokugubungela ubhedu, imigca yonikezelo lwamandla ehambelanayo iqala ukuqiniswa: 5.0V, 3.3V, njl. Ngale ndlela, izakhiwo ezininzi ezinokukhubazeka zemilo eyahlukeneyo zenziwe.

2. Ukudibanisa indawo enye yezizathu ezahlukeneyo, indlela yokudibanisa nge-0 ohm ukumelana okanye ubuhlalu bamagnetic okanye inductance. 3. Ukufakwa kobhedu kufutshane ne-crystal oscillator.I-crystal oscillator kwisekethe ngumthombo we-high-frequency emission source.Indlela yokunxiba ubhedu malunga ne-crystal oscillator, kwaye emva koko ugaye igobolondo le-crystal oscillator ngokwahlukileyo. 4. Isiqithi (indawo efileyo) ingxaki, ukuba ucinga ukuba inkulu kakhulu, ngoko ayiyi kubiza imali eninzi ukuchaza umhlaba ngokusebenzisa kwaye uyongeze. 5. Ekuqaleni kocingo, ucingo lomhlaba kufuneka luphathwe ngokulinganayo, kwaye ucingo lomhlaba kufuneka luhanjiswe kakuhle xa luhamba.Awukwazi ukuthembela ukongezwa kwe-vias emva kokugquma ubhedu ukuphelisa isikhonkwane somhlaba soqhagamshelwano.Esi siphumo sibi kakhulu. 6. Kungcono ukuba ungabi neekona ezibukhali ebhodini ( 7. Musa ukuthululela ubhedu kwindawo evulekileyo yocingo kwinqanaba eliphakathi kwebhodi le-multi-layer.Kuba kunzima kakhulu kuwe ukwenza olu bhedu lugalele "umhlaba olungileyo". 8. Izinyithi ngaphakathi kwesixhobo, ezifana nezitshixo zokushisa zetsimbi, imivalo yokuqinisa isinyithi, njl., Kufuneka "isekelwe kakuhle". 9. Ibhloko yensimbi yokutshatyalaliswa kobushushu ye-stabilizer ye-voltage emithathu kufuneka ibekwe kakuhle.Ibhanti yokuzahlula emhlabeni kufuphi ne-crystal oscillator kufuneka isekelwe kakuhle.Ngelizwi nje: ukuba i-copper cladding kwi-PCB ijongiwe ngokufanelekileyo, ngokuqinisekileyo iya kuba "yinzuzo ngaphezu kweengozi".Inokunciphisa indawo yokubuya yomgca wesignali kunye nokunciphisa ukuphazamiseka kwe-electromagnetic yesiginali ukuya ngaphandle.
