Chii chinonzi multi-layer circuit board, uye ndezvipi zvakanakira multi-layer PCB redunhu bhodhi?Sezvinoratidzwa nezita racho, multi-layer circuit board zvinoreva kuti bhodhi redunhu rine zvidimbu zvinopfuura zviviri zvinogona kunzi multi-layer.Ndakaongorora kuti bhodhi redunhu rakapetwa kaviri rakaita sei, uye bhodhi redunhu rakawanda rinopfuura zvidimbu zviviri, zvakadai sezvikamu zvina, zvidimbu zvitanhatu, Uriri hwesere uye zvichingodaro.Ehe, mamwe magadzirirwo ane matatu-layer kana mashanu-layer maseketi, anonziwo akawanda-layer PCB wedunhu mabhodhi.Yakakura kupfuura iyo conductive wiring dhizaini yeaviri-layer board, iwo akapatsanurwa akapatsanurwa ne insulating substrates.Mushure memutsetse wega wega wemaseketi kudhindwa, imwe neimwe dhizaini yemaseketi inoputirwa nekudzvanya.Mushure meizvozvo, maburi ekuchera anoshandiswa kuona mafambisirwo pakati pemitsetse yega yega.
Kubatsira kwe-multi-layer PCB circuit boards ndeyokuti mitsetse inogona kugoverwa muzvikamu zvakawanda, kuitira kuti zvigadzirwa zvakanyatsojeka zvinogona kugadzirwa.Kana zvidiki zvigadzirwa zvinogona kuitwa neakawanda-layer mabhodhi.Zvakadai se: nharembozha yedunhu mabhodhi, diki mapurojekita, marekodha ezwi uye zvimwe zvigadzirwa zvakakura.Uye zvakare, akawanda akaturikidzana anogona kuwedzera kuchinjika kwedhizaini, kutonga kuri nani kwekusiyanisa impedance uye imwe-inopera impedance, uye kubuda kuri nani kwemamwe masaini ma frequency.
Multilayer circuit boards chigadzirwa chisingadzivisiki chekugadzirwa kwekombiyuta yemagetsi munzira yekukurumidza, yakawanda-inoshanda, hukuru hukuru uye huwandu huduku.Nekuenderera mberi kwekuvandudza tekinoroji yemagetsi, kunyanya kushandiswa kwakadzama uye kwakadzama kwemaseketi akakura uye ekupedzisira-akakura-akabatanidzwa, maseketi akadhindwa akawanda ari kukurumidza kusimudzira munzira yehudzvinyiriri hwepamusoro, kunyatsojeka, uye nhamba dzepamusoro. ., Gomba bofu rakavigwa gomba rakakwirira ndiro ukobvu aperture reshiyo uye mamwe matekinoroji kuzadzisa zvinodiwa pamusika.
Nekuda kwekudiwa kwemaseketi ekumhanya-mhanya mukombuta uye maindasitiri emuchadenga.Izvo zvinodiwa kuti uwedzere kuwedzera dhizaini yekurongedza, pamwe nekuderedzwa kwehukuru hwezvikamu zvakapatsanurwa uye kukurumidza kusimudzira kwemicroelectronics, michina yemagetsi iri kusimukira munzira yekudzikisa ukuru uye kunaka;nekuda kwekuganhurirwa kwenzvimbo iripo, hazvibviri kune rimwe-side-side uye kaviri-sided akadhindwa mabhodhi Kuwedzera kuwedzera kwekusangana kwegungano kunowanikwa.Nokudaro, zvakakosha kufunga nezvekushandisa zvakanyanya kudhindwa maseketi pane maviri-sided layers.Izvi zvinogadzira mamiriro ekubuda kwemultilayer circuit board.
