Munyika iri kukurumidza kushanduka yetekinoroji, kudiwa kwemidziyo yemagetsi idiki, yakareruka, uye ine simba rakawanda yakonzera kugadzirwa kwemultilayer printed circuit boards (PCBs).Aya mabhodhi ematunhu akaoma ave chikamu chakakosha chemagetsi emazuva ano, achivabvumira kuita mabasa akaoma zvinobudirira.Mune ino blog, isu tichaongorora mukati mekuoma kwema-multi-layer PCB uye kukurukura maitiro avo, mabhenefiti, uye zvakakosha mashandisirwo mumaindasitiri akasiyana.
Multilayer PCB, sezvinoreva zita racho, inoumbwa nezvikamu zvakawanda zvemaseketi.Kusiyana neyakajairwa imwe- kana mbiri-mativi maPCB ayo anogona chete kubata mashoma edunhu kuomarara, multilayer PCBs inogona kugarisa network yakakura yetrace, zvinongedzo, uye zvikamu.Izvo zvinosanganisira substrate zvinhu (kazhinji FR-4) uye akawanda akaturikidzana emhangura akapatsanurwa ne insulating layer.Aya akaturikidzana akabatanidzwa nemaburi madiki anonzi vias, achibvumira masaini uye simba kuyerera pakati pezvikamu zvakasiyana.
Zvakanakira zve multilayer PCB:
Iko kusanganiswa kwematanho akawanda muPCB dhizaini inopa akati wandei mabhenefiti.Chekutanga, multilayer PCBs inobvumira yakakwirira yedunhu density, ichiita kuti ive yakanakira compact yemagetsi zvishandiso senge ma smartphones, malaptop, uye zvinopfeka.Pamusoro pezvo, ivo vanopa zvirinani impedance control, kuderedza kupindira uye kugadzirisa chiratidzo chekuvimbika.Multilayer PCBs zvakare yakavandudza kupisa kupisa zvivakwa nekuda kwenzvimbo yavo yakakura, iyo inobatsira kutonhora kwakanaka kwezvikamu.Pamusoro pezvo, ivo vanoratidza yakagadziridzwa magetsi emagetsi kuenderana (EMC), kuderedza mukana wekuchinjika uye kuve nechokwadi chekuita kwakavimbika.
Zvishandiso zveakawanda-layer PCB:
Nekuda kwekusiyana kwayo uye akawanda mabhenefiti, multilayer PCBs anoshandiswa zvakanyanya munzvimbo dzakasiyana siyana.Muindasitiri yemotokari, anoshandiswa mumhando yepamusoro yekubatsira mutyairi masisitimu (ADAS), injini yekudzora zvikamu (ECUs) uye infotainment masisitimu.Iwo aerospace uye edziviriro zvikamu zvinotsamira pamultilayer PCBs kuita masisitimu ekutaurirana, radar uye masisitimu ekufambisa.Mundima yezvokurapa, anoshandiswa mumidziyo yakadai semichina yeMRI, ma ultrasound scanners uye michina yekutarisa varwere.Pamusoro pezvo, maPCB akawanda akakosha mumaindasitiri otomatiki, masisitimu emagetsi anovandudzwa, uye zvemagetsi zvevatengi.
Maonero eramangwana uye mhedziso:
Sezvo tekinoroji iri kuramba ichifambira mberi pamwero usati wamboitika, maPCB mazhinji ave chikamu chakakosha chenyika yemagetsi.Sezvo kudiwa kweminiaturization uye kushanda kwepamusoro kuri kuramba kuchiwedzera, basa rema PCB akawanda richaramba richikura.Vatsvagiri uye mainjiniya vanoramba vachiongorora zvinhu zvitsva uye matekiniki ekugadzira kuti vawedzere kuvandudza dhizaini nekuita kwePCB dzakawanda.
Muchidimbu, maPCB akawanda akachinja indasitiri yezvemagetsi nekupa compactness, mashandiro ari nani, uye kuvimbika.Ivo vakaita zvakakosha mukuvandudza kwezvidiki, zvinonyanya kushanda zvemagetsi zvigadzirwa zvinoumba hupenyu hwedu hwezuva nezuva.Sezvo isu tichienda kune yakangwara, yakabatana nyika, remangwana remultilayer PCBs rine mukana wakakura wekufambisa mberi tekinoroji.
