1. Ukuqulunqwa kweSlots ngexesha lenkqubo yoyilo lwePCB kubandakanya:

Ukuncamathisela okubangelwa kukwahlulwa kwamandla okanye iinqwelomoya; Xa zininzi izinto ezahlukeneyo zoncedo okanye amabala kwi-PCB, akunakwenzeka ukuba zabele inqwelomoya epheleleyo kwinethiwekhi nganye yokuhambisa amandla kunye nenethiwekhi yomhlaba. Indlela eqhelekileyo yeyokwahlulahlula okanye iCandelo loMkhosi okanye ulwahlulo lomhlaba kwiindiza ezininzi. I-Slots zenziwa phakathi kwezahlulo ezahlukeneyo kwindiza enye.

Imingxunya incinci kakhulu ukuba ibe yi-slots (ngokusebenzisa imingxunya ibandakanya iipads kunye ne-vias); Xa imingxunya idlula kungqingqwa okanye ungqimba lwamandla ngaphandle koqhagamshelo lombane, kufuneka ishiywe ishiywe ngokusebenzisa imingxunya yokuzahlula kombane; Kodwa xa imingxunya xa imingxunya isondelelene kakhulu, i-rickacr rings ngaphezulu, i-slots ezenzi.

2. Ifuthe lokutyibilika kwi-EMC ye-EMC yenguqulo yePCB

Ukuhlelwa kuya kuba nefuthe elithile kwi-EMC yeBhodi yePCB. Le mpembelelo isenokuba yinto engeyiyo okanye ilungile. Okokuqala kufuneka siqonde ukuhanjiswa kwangoku kwezimbo zomqondiso wesantya esiphezulu kunye nemiqondiso esezantsi. Kwisantya esisezantsi, ukuhamba ngokuhamba ecaleni kwendlela yokunganyangeki. Umzobo ongezantsi ubonisa indlela xa isantya esisezantsi sihamba ukusuka kwi-A ukuya kwi-B, ukubuya kwayo kwi-BIDS kwindiza yomhlaba ukuya kumthombo. Ngeli xesha, ukuhanjiswa okukhoyo okwangoku.

Kwisantya esiphezulu, ifuthe lokukhuphela indlela yokubuya komqondiso liya kudlula kwimpembelelo yokuxhathisa. I-Eight-Isantya sokubuyela kwisantya siya kuhamba ecaleni kwendlela ephantsi. Ngeli xesha, ukusasazwa komphezulu wangoku kunqabile, kwaye umqondiso wokubuya ugxilwe phantsi komgca womqondiso kwinqwaba.

Xa kukho iisekethe ezingahambelani kwi-PCB, "Ukwahlulahlula umhlaba" kuyafuneka, oko kukuthi, iinqwelomoya zomhlaba zisekwe ngokwahlukeneyo ngokubonakalayo, imiqondiso yedijithali, isantya esiphezulu, kunye ne-SEPE-SPHEY NOKHUSELEKO NOKUGQIBELA. Ukusuka ekuhanjisweni kwesantya esiphezulu sesantya esiphezulu kunye nesantya esiphezulu esinikezwe apha ngasentla, inokuqondwa ngokulula ukuba isiseko esahlukileyo sinokuthintela isuti yesekethe ingenzi isketsi engahambelaniyo kunye nokuthintela i-coupel yomhlaba oqhelekileyo.

Kodwa ngaphandle kwezimpawu zesantya esiphakamileyo okanye imiqondiso esezantsi, xa imigca yomqondiso kwindiza yamandla okanye kwindiza emiselweyo, iingxaki ezininzi ziya kwenzeka, kubandakanya:

Ukwandisa indawo yangoku iloop yonyusa i-coop engasebenziyo, yenza iziphumo zijongeka lula kuOscillate;

Kwimigca ephezulu yesantya esiphezulu efuna ulawulo olungqongqo olungqongqo kwaye liyenziwa ngokwemodeli ye-stripline, imodeli yomhluzi iya kutshatyalaliswa ngenxa yokutsala inqwelomoya okanye inqwelomoya okanye iphantsi kwimpazamo enkulu. iingxaki zesondo;

Ukonyusa umthamo wokuphuma ube yindawo kwaye ithethwe kukuphazamiseka ekuphazamiseni kwimimandla yemagnetic yendawo;

I-voltaged ye-voltancy floctency ihhlisekileyo kwi-Loop engasebenziyo yeyokuphuhliswa kwemida yemitha, kwaye imisebe ye-Pro eqhelekileyo iveliswa kwiintambo zangaphandle;

Yongeza ukubakho kwe-rossancy ye-rosstalk ephezulu kakhulu kunye nezinye iziphaluka ebhodini.

Xa kukho iisekethe ezingahambelani kwi-PCB, "Ukwahlulahlula umhlaba" kuyafuneka, oko kukuthi, iinqwelomoya zomhlaba zisekwe ngokwahlukeneyo ngokubonakalayo, imiqondiso yedijithali, isantya esiphezulu, kunye ne-SEPE-SPHEY NOKHUSELEKO NOKUGQIBELA. Ukusuka ekuhanjisweni kwesantya esiphezulu sesantya esiphezulu kunye nesantya esiphezulu esinikezwe apha ngasentla, inokuqondwa ngokulula ukuba isiseko esahlukileyo sinokuthintela isuti yesekethe ingenzi isketsi engahambelaniyo kunye nokuthintela i-coupel yomhlaba oqhelekileyo.

Yonyusa ukubakho kwe-frequng certalk ye-rosstalk ephezulu kunye nezinye iziphaluka ebhodini

I-3. Iindlela zokuyila i-PCB zokutyibilika

Ukulungiswa kwee-rooves kufuneka kulandele le migaqo ilandelayo:

Kwimigca ephezulu yesantya esiphezulu efuna ulawulo olungqongqo, ukulandelwa kwabo akuvumelekanga ngokungqongqo ekunqamlezweni ngokwahlukeneyo ukuphepha ukubangela ukunqunyulwa kwengqibelelo;

Xa kukho iskekethe elingahambelaniyo kwi-PCB, ukwahlulwa komhlaba kufuneka kwenziwe, kodwa ukwahlukana akufuneki kubangele imigca yesantya esiphezulu ukuwela i-wiring yahlula-hlukeneyo, kwaye zama ukungabinamiziselo ephantsi.

Xa i-rateng kwiindawo ezihamba kwiindawo ezingenakuthintelwa, ibhulorho kufuneka yenziwe;

Isinxibelelanisi (sangaphandle) akufuneki sibekwe kumhlaba ophantsi. Ukuba kukho umahluko omkhulu onokubakho phakathi kwenqaku lenqaku kwaye inqaku le-B kwi-thermar ephantsi kumzobo, imida yemodyuli eqhelekileyo inokufakwa kwi-leble yangaphandle;

Xa uyila i-PCBS yeZifundo eziNgxibezini eziNgxibezi, ngaphandle kokuba kukho iimfuno ezizodwa, kuya kufuneka uqiniseke ukuba inethiwekhi yomhlaba ijikeleze iPIN nganye. Unokucwangcisa kwakhona iNethiwekhi yePlanethi kwaye ucwangcise izikhonkwane ukuze uqinisekiswe ukuqhubeka kwendiza ephantsi kwaye kuthintele ukuveliswa kwe-slotting
