Yintoni ibhodi yesekethe enamaleko amaninzi, kwaye zeziphi iingenelo zebhodi yesekethe ye-multi-layer PCB?Njengoko igama libonisa, ibhodi yesekethe ye-multi-layer ithetha ukuba ibhodi yesekethe enemigangatho engaphezu kwembini ingabizwa ngokuba yi-multi-layer.Ndiye ndahlalutya ukuba yintoni ibhodi yesekethe enamacala amabini ngaphambili, kwaye ibhodi yesekethe ye-multi-layer ingaphezulu kwamaleko amabini, njengemigangatho emine, imigangatho emithandathu, umgangatho wesibhozo njalo njalo.Ewe kunjalo, ezinye iziyilo zineentambo ezintathu okanye ezinemijikelezo emihlanu, ekwabizwa ngokuba ziibhodi zesekethe zePCB ezinomaleko amaninzi.Enkulu kunomzobo we-wiring we-conductive webhodi leebhodi ezimbini, iileyile zihlukaniswe ngama-substrates e-insulating.Emva kokuba uluhlu ngalunye lweesekethe luprintwe, uluhlu ngalunye lweesekethe lugqitywe ngokucinezela.Emva koko, imingxuma yokugaya isetyenziselwa ukuqonda ukuqhuba phakathi kwemigca yoluhlu ngalunye.
Inzuzo yeebhodi zeesekethe ze-PCB ezininzi kukuba imigca ingasasazwa kwiileya ezininzi, ukwenzela ukuba iimveliso ezichanekileyo zinokuyilwa.Okanye iimveliso ezincinci zinokuqondwa ngamabhodi anemigangatho emininzi.Ezinjena: iibhodi zesekethe yefowuni ephathwayo, iiprojektha ezincinci, iirekhoda zelizwi kunye nezinye iimveliso ezinobunzima obukhulu.Ukongeza, iileya ezininzi zinokunyusa ukuguquguquka koyilo, ulawulo olungcono lwe-impedance yokwahlula kunye ne-impedance enesiphelo esinye, kunye nesiphumo esingcono kwezinye iifrikhwensi zomqondiso.
Iibhodi zeesekethe ze-Multilayer ziyimveliso engenakuphepheka yokuphuhliswa kobuchwepheshe be-elektroniki kwicala lesantya esiphezulu, i-multi-function, umthamo omkhulu kunye nomthamo omncinci.Ngophuhliso oluqhubekayo lwetekhnoloji ye-elektroniki, ngakumbi ukusetyenziswa okubanzi kunye nobunzulu beesekethe ezihlanganisiweyo ezinkulu kunye nezinkulu kakhulu, iisekethe eziprintiweyo ezininzi zikhula ngokukhawuleza kwicala loxinzelelo oluphezulu, ukuchaneka okuphezulu, kunye namanani aphezulu. ., Umngxuma oyimfama wangcwatywa umngxuma ipleyiti ukutyeba ubukhulu aperture ratio kunye nobunye ubugcisa ukuhlangabezana neemfuno zemarike.
Ngenxa yemfuno yeesekethe zesantya esiphezulu kwikhompyuter kunye ne-aerospace kumashishini.Kufunwa ukunyusa ngakumbi ubuninzi bokupakisha, kunye nokunciphisa ubungakanani bamacandelo ahlukeneyo kunye nophuhliso olukhawulezayo lwe-microelectronics, izixhobo zombane ziphuhliswa kwindlela yokunciphisa ubungakanani kunye nomgangatho;ngenxa yokunciphisa indawo ekhoyo, akunakwenzeka kwiibhodi eziprintiweyo ezinecala elinye kunye necala eliphindwe kabini Ukunyuka okungaphezulu koxinzelelo lwendibano kufezekiswa.Ngoko ke, kuyimfuneko ukuqwalasela ukusebenzisa iisekethe eziprintiweyo ezingaphezulu kunemigangatho ephindwe kabini.Oku kudala iimeko zokuvela kweebhodi zeesekethe ezininzi.
