yintoni i-pcm kunye ne-pcb

Ubunjineli bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bobuchwephesha bukhula ngesantya esimangalisayo.Ngokunyuka kwezixhobo zombane ezifana nee-smartphones, iilaptops, kunye nethekhnoloji enxibekayo, ukubaluleka kweebhodi zeesekethe eziprintiweyo (PCBs) akunakugxininiswa kakhulu.Nangona kunjalo, kuhlala kukho ukubhideka phakathi kwe-PCB kunye ne-PCM, ebangela ukuba abantu abaninzi bazisebenzise ngokutshintshanayo.Ke, yintoni umahluko phakathi kwala magama mabini kwaye yiyiphi indima abayidlalayo kubunjineli bombane?

Ziziphi ii-PCM?

I-PCM imele i-Pulse Code Modulation, indlela esetyenziswa ukumela ngedijithali kunye nokubethelela imiqondiso ye-analog.Le ndlela iqhele ukusetyenziselwa ukurekhoda kunye nokudlala kwakhona.Inkqubo ye-PCM ibandakanya ukuguqula isignali ye-analog, njengezandi zesandi, zibe kuthotho lwee-1s kunye no-0s ezinokudlalwa emva koko phantse ngesandi esifana nesandi somgangatho we-analog yasekuqaleni.Umlinganiselo wesampulu yokuguqulwa kwe-PCM uphakathi kwe-8 kHz kunye ne-192 kHz, kwaye ubunzulu be-bit ngesampulu nganye buphakathi kwe-16 kunye ne-32 bits.

Yintoni iBhodi yeSekethe eprintiweyo?

Ibhodi yesekethe eprintiweyo (PCB) yibhodi esebenzisa iingoma zokuqhuba, iipads, kunye nezinye iimpawu ezifakwe kumaphepha obhedu alaminated kwi-non-conductive substrate ukuxhasa ngoomatshini kunye nokudibanisa ngombane amacandelo e-elektroniki.Ezi bhodi zizinto ezisisiseko kwiinkqubo ezininzi ze-elektroniki, zibonelela ngeqonga elizinzileyo le-analog kunye neesekethe zedijithali.Ii-PCB zinokuba calanye, zinamacala amabini okanye zine-multi-layered, kuxhomekeke kubunzima kunye nokusebenza kwenkqubo yombane.

Umahluko phakathi kwePCM kunye nePCB

I-PCM kunye ne-PCB ziitekhnoloji ezahlukeneyo ezisebenza kwiinkalo ezahlukeneyo zobunjineli bombane.I-PCM bubuchule obusetyenziswa ukubethelela kunye nokucacisa iisignali ze-analog, ngelixa i-PCB iyinxalenye ebonakalayo yezindlu kwaye idibanisa amacandelo e-elektroniki.IiPCM zibalulekile ekurekhodweni kweteknoloji, ngelixa iiPCB zibalulekile kwiinkqubo ezininzi zombane.

Omnye umahluko ophambili phakathi kweePCM kunye neePCB yindima eziyidlalayo kwiinkqubo zombane.Ii-PCM zisetyenziselwa ukubamba ngokuchanekileyo, ukugcina kunye nokudlala izibonakaliso zesandi, ngelixa ii-PCB zisetyenziselwa ukuxhasa amacandelo e-elektroniki kunye neesekethe, ukubonelela ukuzinza komatshini kunye nokudibanisa kombane kwiinkqubo ezininzi ze-elektroniki.Kwakhona, ii-PCBs zinokumaleko amaninzi kwaye zintsonkothe, ngelixa i-PCM iqhele ukuba yitekhnoloji elula kakhulu.

Omnye umahluko obalulekileyo phakathi kwe-PCM kunye neePCB kukwakheka kunye nokwakheka kwazo.I-PCM iqulethe uluhlu lwee-1 kunye nee-0 ezimele umqondiso we-analog, ngelixa i-PCB yindibano yomzimba eyenziwe ngamashiti obhedu, i-substrates e-non-conductive, kunye nezinye iinqununu zesekethe eziprintiweyo.Enye yeyedijithali kwaye enye yeyomzimba, ebonisa ubume bokusebenza kwePCM kunye nojongano lwePCB.

Isishwankathelo, i-PCM kunye ne-PCB zitekhnoloji ezimbini ezahlukeneyo ngokupheleleyo kwicandelo lobunjineli be-elektroniki.Ii-PCM zidlala indima ebalulekileyo ekurekhodweni komsindo kunye nokulungiswa komqondiso, ngelixa ii-PCBs zingumqolo weenkqubo ezininzi ze-elektroniki.Ngelixa itekhnoloji zimbini zabelana ngokufana kwindlela yazo yokwenziwa kolwazi kunye nokusetyenziswa kweempawu zedijithali, zisetyenziswa ngokwahlukileyo kubunjineli bombane.

Ukuqukumbela, thatha umzuzwana ukuqonda indima ebalulekileyo edlalwa ziiPCB kwiinkqubo zombane.Ngaphandle kweli candelo lisisiseko, izixhobo zombane ezifana nee-smartphones, iilaptops okanye izixhobo zombane zasekhaya azinakukwazi ukusebenza njengoko zisenza namhlanje.Ke qiniseka ukuba unika ii-PCBs zakho ingqalelo eziyifaneleyo kwaye uqiniseke ukuba ziwulungele umsebenzi!
