Njengoko itekhnoloji iqhubela phambili kwaye izixhobo ziba nzima ngakumbi, ukuqinisekisa ukuba unikezelo lwamandla oluzinzileyo luya lubaluleke kakhulu.Oku kuyinyani ngakumbi kwi-6-layer PCBs, apho uzinzo lwamandla kunye nemiba yengxolo inokuchaphazela kakhulu ukuhanjiswa komqondiso obuthathaka kunye nosetyenziso lwe-voltage ephezulu. Kule posi yebhlog, siza kuphonononga iindlela ezahlukeneyo zokujongana nale miba ngempumelelo.

1. Qonda uzinzo lobonelelo lwamandla:

Uzinzo lonikezelo lwamandla lubhekiselele ekukwazini ukubonelela amandla ombane angaguqukiyo kwaye akhoyo kumacandelo e-elektroniki kwiPCB. Nakuphi na ukuguquguquka okanye utshintsho kumandla kunokubangela ukuba la malungu angasebenzi kakuhle okanye wonakaliswe. Ngoko ke, kubalulekile ukuchonga kunye nokulungisa nayiphi na imiba yozinzo.

2. Chonga iingxaki zengxolo yobonelelo lwamandla:

Ingxolo yonikezelo lwamandla lutshintsho olungafunekiyo kumbane okanye kumanqanaba angoku kwiPCB. Le ngxolo inokuphazamisana nokusebenza okuqhelekileyo kwamalungu anovakalelo, okubangela iimpazamo, ukungasebenzi kakuhle, okanye ukuthotywa kokusebenza. Ukuthintela iingxaki ezinjalo, kubalulekile ukuchonga kunye nokunciphisa imiba yengxolo yobonelelo lwamandla.

3. Itekhnoloji yokuthoba:

Esinye sezizathu eziphambili zokuzinza konikezelo lwamandla kunye neengxaki zengxolo kukumisa okungafanelekanga. Ukusebenzisa iindlela ezifanelekileyo zokubeka umhlaba kunokuphucula kakhulu uzinzo kunye nokunciphisa ingxolo. Qwalasela ukusebenzisa inqwelomoya eqinileyo yasemhlabeni kwi-PCB ukunciphisa amarhintyela aphantsi komhlaba kunye nokuqinisekisa ukubakho kwereferensi efanayo. Ukongezelela, ukusebenzisa iiplani zomhlaba ezihlukeneyo ze-analog kunye namacandelo edijithali kuthintela ukudibanisa ingxolo.

4. Ukuqhawula i-capacitor:

I-Decoupling capacitors ebekwe ngokucwangcisekileyo kwi-PCB yokufunxa kwaye ihluze ingxolo ephezulu, ukuphucula uzinzo. Ezi capacitors zisebenza njengemithombo yamandla yendawo, inika amandla ngokukhawuleza kumacandelo ngexesha leziganeko ezidlulayo. Ngokubeka i-decoupling capacitors kufuphi nezikhonkwane zamandla ze-IC, ukuzinza kwenkqubo kunye nokusebenza kunokuphuculwa kakhulu.

5. Inethiwekhi yokuhanjiswa kwe-impedance ephantsi:

Ukuyila i-low-impedance network distribution networks (PDNs) ibalulekile ekunciphiseni ingxolo yokunikezelwa kwamandla kunye nokugcina uzinzo. Cinga ukusebenzisa umkhondo obanzi okanye iinqwelomoya zobhedu kwiintambo zamandla ukunciphisa i-impedance. Ukongeza, ukubeka i-bypass capacitors kufutshane nezikhonkwane zamandla kunye nokuqinisekisa ukulandelwa kwamandla amafutshane kunokunyusa ngakumbi ukusebenza kwe-PDN.

6. Uhluzo kunye neteknoloji yokukhusela:

Ukukhusela imiqondiso ebuthathaka kwingxolo yonikezelo lwamandla, kubalulekile ukusebenzisa iindlela ezifanelekileyo zokucoca kunye nokukhusela. Sebenzisa isihluzo esisezantsi ukuthomalalisa ingxolo yefrikhwensi ephezulu ngelixa uvumela uphawu olufunekayo ukuba ludlule. Ukuphumeza imilinganiselo yokukhusela njengeenqwelo-moya eziphantsi komhlaba, i-copper cladding, okanye iintambo ezikhuselekileyo zinokunceda ukunciphisa ukudibanisa ingxolo kunye nokuphazamiseka kwimithombo yangaphandle.

7. Umaleko wamandla ozimeleyo:

Kwizicelo zombane ophezulu, kuyacetyiswa ukuba kusetyenziswe iindiza zamandla ezahlukeneyo kumanqanaba ombane ahlukeneyo. Oku kwahlula kunciphisa umngcipheko wokudityaniswa kwengxolo phakathi kweendawo ezahlukeneyo zombane, kuqinisekisa uzinzo lonikezelo lwamandla. Ukongeza, ukusetyenziswa kwetekhnoloji efanelekileyo yokuzahlula, njengeziguquli zodwa okanye ii-optocouplers, kunokuphucula ngakumbi ukhuseleko kunye nokunciphisa imiba enxulumene nengxolo.

8. Ukulinganisa kwangaphambili kunye nohlalutyo lwesakhiwo:

Ukusebenzisa izixhobo zokulinganisa kunye nokuqhuba uhlalutyo lwe-pre-layout kunokunceda ukuchonga ukuqina okunokubakho kunye nemiba yengxolo phambi kokugqiba uyilo lwePCB. Ezi zixhobo zivavanya ingqibelelo yamandla, imfezeko yomqondiso, kunye nemiba yokuhambelana kwe-electromagnetic (EMC). Ngokusebenzisa ubuchule boyilo obuqhutywa ngukulinganisa, umntu unokujongana nale miba ngokuqhubekayo kwaye andise uyilo lwePCB ukomeleza ukusebenza.

Ukuququmbela:

Ukuqinisekisa uzinzo lobonelelo lwamandla kunye nokunciphisa ingxolo yonikezelo lwamandla yingqwalasela ephambili yoyilo lwePCB oluyimpumelelo, ngakumbi kuthumelo lomqondiso olubuthathaka kunye nokusetyenziswa kwamandla ombane aphezulu. Ngokusebenzisa iindlela ezifanelekileyo zokumisa umhlaba, ukusebenzisa i-capacitors yokuqhawula, ukuyila amanethiwekhi okusabalalisa okuphantsi kwe-impedance, ukusebenzisa imilinganiselo yokucoca kunye nokukhusela, kunye nokuqhuba ukulinganisa okwaneleyo kunye nokuhlalutya, le miba ingaqwalaselwa ngokufanelekileyo kwaye unikezelo lwamandla oluzinzileyo noluthembekileyo luphunyeziwe. Gcina ukhumbula ukuba ukusebenza kunye nobude bePCB eyilwe kakuhle ixhomekeke kakhulu kwingqalelo kunikezelo lwamandla uzinzo kunye nokunciphisa ingxolo.
