Kugadzira PCB yeRO4835T yeTin RF Cores

Kugadzirwa kwePCB muRO4835T kunonyatsoenderana nechikamu chepakati chakatetepa che stackup. Kana jira re dielectric rava rakatetepa, kunyoreswa, kutsanangurwa kwemhangura uye ukobvu hwekupedzisira hwakadzvanywa zvinova zvakakosha kune mhedzisiro yeRF. RO4835T inobatsira kana jira reRF richifanira kufamba mukati me multilayer stack pasina kushandisa ukobvu hwe microwave core yakajairika. Saka sarudzo yekutenga yakabatana ne board architecture: dense radio modules, phased-array feed networks, compact transceivers uye high-layer RF boards dzinoda thin controlled dielectrics, short vertical transitions uye stable inner-layer routing.

Highleap Electronics inogadzira ma prototypes eRO4835T uye ma multilayer ekugadzira ane ongororo ye stackup yakakora, spread-glass control, bondply selection, registration compensation uye optional assembly. Highleap Electronics inotarisa padambudziko rekuvaka rakatetepa pane kudzokorora tsananguro yakajairika yeRF laminate.

Matanda akawanda eRO4835 akatetepa anoda kutariswa zvakanyanya pakukora kwe dielectric kwakapedzwa uye kunyoreswa kwe layer. Saka hurukuro yekugadzira inotarisa pahukama huripo pakati pekuvakwa kwe dielectric yakatetepa, copper geometry, lamination uye impedance verification.

Nei Makori Matete eRF Akakosha Mukugadzirwa kwePCB Dzakasiyana-siyana

Dielectric yemukati yakatetepa inogona kudzikira kuburikidza nehurefu, kuisa reference plane pedyo ne stripline inodzorwa uye kubvumira RF layers kuti dzishande pamwe chete ne digital, power uye control circuitry mubhodhi rimwe chete. Inogonawo kuvandudza routing density muma compact modules. Mabhenefiti aya anongoitika chete kana dhizaini ichishandisa core thin thin thin kubva pakutanga; kutsiva core thin layout kunonoka kunogona kuchinja impedance, coupling uye copper geometry.

Ruzivo rwemagetsi rwakanangana nekukora

Data reRO4835T rinoburitswa nehukuru hwepakati. Magadzirirwo e2.5, 3, 4 uye 5 mil haafanirwe kutorwa sechinhu chimwe chinochinjika. Kodhi chaiyo yepakati neyendarira inofanira kubatanidzwa pa stackup, nekuti modhi, hupamhi hwemutsara uye mhedzisiro ye lamination zvinoenderana nekugadzirwa ikoko. Kufamba pakati pekuvaka kwakatetepa nezvimwe kunofanirwa kuongororwa zvichienderana nekugadzirwa kwebhodhi reRO4835 RF , nezvinodiwa zvakasiyana zvekukora uye kubatana.

Sei girazi rakapararira richibatsira asi risingabvisi kuchinja kwemaitiro

Kugadzirwa kwegirazi rakapararira kunogona kuderedza musiyano we resin negirazi remunharaunda zvichienzaniswa nekuruka kwakaomarara. Izvi zvinotsigira nzira yeRF yakanaka, asi hazvibvisi kukanganiswa nekukora kwapera, copper profile kana kufamba kwemifananidzo. Mugadziri wefield solver anofanira kushandisa dhizaini chaiyo, uye chinyorwa chekutanga chinofanira kubatanidza mhinduro yakafanotaurwa ne stack yakavakwa.

Kuti uwane ruzivo rwakakura pamusoro pemagadzirirwo, ona gwara reHighleap rekushandisa PCB stackup.

Chimiro chezvinhu: zita rechigadzirwa cheRogers rinoshandiswa kuratidza laminate yakatarwa yekuvaka PCB. Highleap Electronics inopa kugadzirwa nekubatanidzwa kwePCB, nepo laminate ichiwanikwa uye ichisimbiswa yoga.

Kugadzira PCB Yakatetepa yeRO4835T Pasina Matambudziko Ekunyoresa

Dambudziko guru remufekitori nderekuchengetedza RF layer yakatetepa yakarongeka uye yakagadzikana kuburikidza nemifananidzo, kubatana uye kupisa kwakawanda. Kugadziriswa kwemukati melayer, nzira yekushandisa, copper balance uye press sequence zvinofanirwa kuongororwa zvisati zvaitwa panelization. Dhizaini ine sequential lamination, blind vias kana multiple thin RF cores inoda bhajeti rekunyoresa kwega kwega cycle, kwete imwe final outline tolerance.

Sarudzo dzeEtch nemhangura pazvikamu zvitete

Nzvimbo yakatetepa ye dielectric inowanzo gadzira geometry yakamanikana yemutsara. Ukobvu hwekupedzisira hwemhangura, chimiro cherutivi uye plating zvinofanirwa kuiswa mu impedance model. Dhirowa inofanira kutaura kana chinhu chakakosha chiri mutsetse wakapedzwa, impedance kana critical coupling gap. Kana firita kana coupler iri pachikamu chemukati, kuongorora zvakananga kunova kwakaoma mushure mekunyungudika, saka zvinyorwa zve inner-layer AOI uye zvinyorwa zvechinyorwa chekutanga zvinova zvakakosha. Highleap inobata core yakatetepa sechinhu chakatsanangurwa chekugadzira pane kungoshandisa resipi yakajairika ye multilayer. Etch compensation, kunyoresa uye finished thin thin count zvinoongororwa zvichienderana nehukuru hweRF husati hwaburitswa artwork. Kukosha kwepfuma chaiyo yezvinhu kunofanirwa kuongororwa zvichienderana nemagwaro emutengesi aripo egiredhi rakatarwa uye kuvaka.

Kana bhodhi richishandisa nzira dzinopfuura imwe chete dzekudhindisa, Highleap inoongorora chivakwa ichi ichipesana ne hybrid lamination uye multilayer PCB manufacturing pane kufunga nezve standard HDI route.

Apo RO4835T Inowedzera Kukosha muCompact RF Products

RO4835T yakasimba muzvigadzirwa apo RF core yakatetepa inochinja magadzirirwo epakeji: mamodule ephased-array, macompact radios, mafirita emukati mechikamu, ma antenna feeds akakora uye mabhodhi e mixed-signal ane RF routing yakavharirwa. Inogona kuwedzera kuomarara kusingadiwe kune antenna board iri nyore ine zvikamu zviviri kana dhizaini inogona kushandisa RO4835 thin core pasina kukanganisa saizi ye enclosure kana kuburikidza ne performance.

Chitupa chechinyorwa chekutanga

Chinyorwa chekutanga cheRO4835T chinobatsira chinofanira kuratidza ukobvu hwakavakwa, kunyoreswa kwemukati mechikamu, geometry yemutsara wakakosha, kuburikidza nemhando uye mhinduro yemagetsi. Kana bhodhi riine RF assembly, hukama hunofanira kusvika pakuburitswa kwakabatana, chinongedzo kana module. Uchapupu uhwu hunova hwaro hwekudzokorora kugadzirwa uye kudzora shanduko.

Ongororo yeRO4835T Stackup, Prototype uye Rutsigiro rweKugadzira

Pakeji yepurojekiti inofanira kusanganisira ukobvu hwepakati chaihwo, copper code, bonding layers, final board thickness, controlled impedance kana RF geometry, kuburikidza ne structure, lamination sequence uye quantity. Zvinhu zvinotsiviwa kana shanduko ku bondply zvinofanirwa kuendeswa kuti zvibvumidzwe nekuti zvinogona kuchinja final dielectric spacing uye resin distribution. Kana building yakaburitswa ichida bonding layer iyi, zvinodiwa zveRO4460G2 bondply stackup ndezve mu finished-thickness review.

Highleap inogona kupa kugadzirwa kwemaprototype, kugadzirwa kwehuwandu hushoma uye kugadzirwa kwekudzokorora, ichiteverwa nekuwana zvikamu uye kuunganidzwa kwePCB kana zvichidikanwa. Nguva yekutungamira inosimbiswa mushure mekunge kuvakwa kwepakati nepakati kwaongororwa. Kune mamodules akakora, hurongwa hwekugadzira hunofanirwa kuongororwa pamwe chete nebhodhi nekuti BGA escape, RF shielding, connector placement uye reflow support zvinogona kukanganisa magadzirirwo e multilayer.

Mibvunzo yakatetepa

Ko RO4835T inogona kutsiviwa neRO4835 yakajairwa pasina kugadziridzwa patsva here? Kwete otomatiki. Ukobvu hwepakati nedata rakaburitswa zvinoenderana nekuvakwa kwaro.

Ko musimboti wakatetepa kupfuura yose ndiyo yakanakisisa nguva dzose here? Kwete. Kubatsira kwemagetsi nekurongedza kunofanira kupfuura kushivirira kwakasimba, kubata uye kunyoresa. Kuti uwane mutengo weRF wakatetepa, sanganisira stackup yakazara, ukobvu hwechinangwa, mhangura, kushivirira impedance uye huwandu. Kana dhizaini iine chinodiwa chechikamu kana kureba kwakasimba zvisingawanzoitiki, tarisa zvinhu izvozvo mudhirowa yekugadzira.

Ko RO4835T ingangoshandiswa chete pazvikamu zvakasarudzwa? Ehe, chero bedzi sisitimu yekubatanidza ne full stack zvikaenderana pamwe chete.
