Ukubaluleka kwee-PCB eziQhelekileyo kakhulu kwiMveliso yee-Elektroniki
Njengoko izixhobo ze-elektroniki ziqhubeka nobunzima kwaye zifuna ngokukhawuleza izinga lokudluliselwa kwesiginaliii-PCB ezisebenza rhoqo ziye zaba yinxalenye ebalulekileyo kuphuhliso lwe isicelo esisebenza kakuhleskulo lonke icandelo lemveliso.
I-frequency ephezulu ibhodi yesekethe eprintiweyoIi-PCB (ii-PCB) ziye zaba yinto ebaluleke kakhulu kwimveliso ye-elektroniki, zibonelela ngeempawu ezahlukeneyo ezibalulekileyo. Ngokwenyani, ii-PCB ezisebenza rhoqo zisasaza ngokufanelekileyo amaza e-electromagneticngelahleko encinci kwaye uqinisekise ukuhamba kwesignali yesantya esiphezuluIimpawu eziphambili ezinxulumene nee-PCB ezisebenza rhoqo ziquka:
Iphantsi Into yokusasazaIi-PCB ezisebenza rhoqo zihlala zibonisa i-dissipation factor ukusuka kwi-0.0019 ukuya kwi-0.025, nto leyo eqinisekisa ukuba zincinci kakhulu. ukulahleka kwesiginali kunye nokugcina izinga lokudluliselwa kwesiginalis.
Iphantsi I-Dielectric ConstantEzi PCBs zine-dielectric constant ephantsi nezinzileyo, ezenza kube lula ukuguda ukuhanjiswa kwamaza rhoqokunye nokunciphisa ukulibaziseka kwesiginali.
Ukumelana neekhemikhali: Amandla ee-PCB ezisebenza rhoqo okumelana neekhemikhali abaluleke kakhulu, okuqinisekisa ukumelana nokugqwala kunye nokufaneleka kwiindawo ezinomngcipheko omkhulu weekhemikhali.
Ukufunxwa Komswakama Ophantsi: Ngenxa yokuba amanzi awafunxwa ngesantya esiphantsi, ii-PCB ezisebenzisa ubuninzi zilungele ukusetyenziswa kwiindawo ezimanzi nezifumileyo.
Iphantsi Uzinzo olunemilinganiselo: Ii-PCB ezisebenza rhoqo ziyaziwa ngokugcina ubungakanani bazo kwaye zingachaphazeleki kutshintsho lobushushu bendalo.
Ngenxa yezi mpawu, ukusetyenziswa kwazo kuxhaphakile. Nangona kunjalo, abayili be-PCB kufuneka baqinisekise ukuba la manyathelo alandelayo alandelwa ngononophelo xa kuyilwa ii-PCB ezisebenza rhoqo:
Misela i-PCB imvamisa yesiginaliKubalulekile ukumisela iimfuno ze-voltage kunye namandla, ukwahlulahlula nayiphi na inqwelo-moya yamandlas, kwaye uvavanye ukulungelelaniswa kwemiqondiso eyahlukeneyo. Ukongeza, ukunciphisa amanqanaba okunyamezela kunye nokunciphisa amanqanaba engxolo zizinto ezibalulekileyo ekufuneka ziqwalaselwe.
Ukufakwa kwebhodiucwangciso: Iimfuno ze umaleko we-stackupkufuneka kucwangciswe ngononophelo, kuthathelwa ingqalelo izinto ezithile kunye nemida yazo.
Ucwangciso lomgangatho: I-PCB kufuneka yahlulwe ibe ngamacandelo, kwaye ukuhlukaniswa okufanelekileyo kugcinwe kwiindawo ezinecandelo ledijithali kunye nele-analog ukuthintela ukuphazamiseka.
Amandla kunye inqwelo-moya yasemhlabenis: Nje ukuba uyilo lwe-PCB luchaziwe, ukuqonda isicwangciso somhlaba kubalulekile. Ukwahlulahlula iplani yomhlaba kubalulekile, kwaye ukufaka i-resistor kunye nomkhondo wesignali ukuphucula indlela yokubuya kubalulekile.
Nciphisa ubungakanani beepateni zomhlaba: Ii-PCB ezisebenzisa amaxesha amaninzi zihlala zineziqwenga ezincinci. Ukunciphisa indawo kunceda ukunciphisa umthamo we-parasitekwaye yonyusa amandla oomatshini.
Indlela isignali yefrikhwensis: Imiqondiso ye-frequency ephezulu iyaziwa ngokuvelisa imitha ephezulu. Ukuhanjiswa ngempumelelo kwemiqondiso ye-frequency kunokuthintela ukuphazamiseka phakathi kwemiqondiso.
Sebenzisa umthetho we-3W: Ukunamathela kumthetho we-3W kuqinisekisa ukuba ukuthembeka kwesignali kuyagcinwa, nto leyo emisela umahluko phakathi kweempawu kunye nokunciphisa isiphumo sokudibanisa.
Sebenzisa umgaqo we-20H: Ukudibanisa phakathi kweenqwelo-moya zomhlaba kunye nezamandla kunokubangela umngcipheko kuyilo lwakho. Umgaqo we-20H uqinisekisa ukuba ubukhulu phakathi kwamandla akufutshane kunye neenqwelo-moya zomhlaba bukhulu kuneenqwelo-moya zamandla.
Ukusetyenziswa kwee-PCB eziQhelekileyo kakhulu
Ukusetyenziswa kwee-PCB ezisebenzisa amaxesha amaninzi kuyanda, apho izicelo ziquka:
Iinkqubo zonxibelelwano kwizixhobo zokucoca, isikhulisis, isikhululo sokunyusas, kunye umamkelis.
Izicelo zomkhosi zokuvelisa iimbumbulu kunye nemipu.
Inkqubo yeradarezikhokela iinqwelo-moya kwaye zithintela iingozi.
Izixhobo zokuxilonga nokubeka iliso ezibalulekileyo kumsebenzi obalulekileyo kushishino lwezonyango.
Ukuququmbela
Ii-PCB ezisebenza rhoqo zibalulekile ekwenzeni ii-PCB ze-elektroniki, zibonelela ngeempawu eziqinileyo ezenza ukuba zibe lukhetho olukhethwayo kwizixhobo ze-elektroniki. Zidlala indima ebalulekileyo kwizicelo ezisebenza kakuhle kwaye zikulungele ukuba zibaluleke ngakumbi ngenxa yobunzima obukhulayo bezixhobo ze-elektroniki kunye nemfuno yamanqanaba okudlulisa isignali ngokukhawuleza.
