RO4360G2 PCB Prototype Kugadzira
Rogers RO4360G2 yakagadzirwa zvakananga kubvisa kukanganiswa uku. Se thermoset laminate yakazadzwa ne hydrocarbon ceramic, inopa Dielectric Constant yakakwira zvisingawanzoitiki (Dk ye6.15) asi inoshanda zvakafanana ne FR-4 yakajairwa. Kune zvikwata zviri kutsvaga kugadzira Rogers RO4360G2 5G PCB yakavimbika, chinhu ichi chinopa kugadzikana kwemagetsi kwebhodhi redunhu rakadhindwa rine frequency yakakwira pasina matambudziko akaoma anokonzerwa nekugadzirisa kwePTFE kwetsika.
Kumbira Mutengo weRO4360G2 Engineering
Muenzaniso weRO4360G2 unoshanduka nekukurumidza unobatsira chete kana chivakwa chacho chadzorwa nechivakwa chakakosha chimwechete chichazoshandiswa gare gare. Saka peji rino rinosimbisa mafaira emuenzaniso, kuomesa stackup, RF-critical dimensions, kuongorora uye kuchinja kubva pachinhu chekutanga kuenda pakugadzirwa.
Zviri Mukati
Sei Uchifanira Kusarudza Dr 6.15 ye5G Miniaturization?
Mukugadzirwa kwemafrequency eredhiyo, saizi chaiyo yedunhu re resonant (senge patch antenna array kana power divider) inoenderana zvakanyanya ne square root ye substrate's dielectric constant.
Nekuchinja kubva pane zvakajairwa zveDk 3.5 RF kuenda kuRO4360G2's Drk ye6.15, mainjiniya ehardware vanogona kuderedza saizi yemuviri yemaRF structures avo neinenge 20% kusvika 30%. Kudzvanywa kwenzvimbo uku kwakakosha zvikuru kune ma densely packed active antenna units (AAUs). Uyezve, chinhu ichi chinochengetedza Dissipation Factor yakaderera (Df = 0.0038 pa10 GHz), zvichiita kuti nzira dzesignal dzakanyatsorongeka dzisakanganiswa nekurasikirwa kwakanyanya kweinsertion.
Magadzirirwo eCore Thermomechanical
Kushanda kwemagetsi hakurevi chinhu kana bhodhi rikakundikana panguva yekunamira kana kuiswa mumunda. RO4360G2 yakazara neceramic, zvichiita kuti ive yakasimba zvikuru kana tichienzanisa negirazi rakarukwa.
| Paramende yakakosha | Kukosha (Zvakajairika) | Mhedzisiro muKugadzira & Kushandisa |
|---|---|---|
| Dielectric Constant (Dk) | 6.15 ± 0.15 | Inoderedza tsoka yemuviri; inoda kuchekwa kwetrace kwakanyatsojeka kuti isvike pazvinangwa zve50-ohm impedance. |
| Dissipation Factor (Df) | 0.0038 @ 10 GHz | Kurasikirwa kwakaderera kwekupinza, kuchengetedza kuvimbika kwechiratidzo chemagetsi emagetsi nema transceivers. |
| Z-Axis CTE | 28 ppm/°C | Inoenderana nekuwedzera kwemhangura; inoita kuti simbi irambe yakasimba panguva yekuyerera kwemvura (PTH) panguva yekuyerera kwayo. |
| Kuchengetedza Kwemhepo | 0.81 W/m/K | Inobatsira mukubvisa kupisa kubva kuzvinhu zvinoshanda zveRF surface-mount zvinobudirira. |
Kunyura Zvakadzika: Kupfuura Kusvibiswa kwePlasma Mukugadzira
Kana ukabvunza chero mainjiniya weCAM kuti chii chinononotsa kugadzirwa kwebhodhi re microwave, mhinduro yacho ndeyekuti "PTFE kuburikidza nekugadzirira." Kana CNC drill bit ikacheka nePTFE, kupisa kwekukweshana kunoita kuti zvinhu zvipararire mukati memukati memhangura. Kubvisa smear iyi kunoda sodium etchants ine chepfu zvakanyanya kana kuvharira mutsetse wekugadzira nekuisa mapaneru mukamuri re plasma re vacuum.
Nekuti RO4360G2 igirazi-reinforced hydrocarbon thermoset, hainyungudike kana kusviba sePTFE.
Fekitori yeRogers RO4360G2 PCB ine hunyanzvi inomhanya zvikuru inogona kuboora, kubvisa tsvina, uye kuisa mabhodhi aya ichishandisa nzira dzakafanana dzemakemikari dzinoshandiswa paFR-4. Iyi "FR-4 processability" ndiyo pfuma yakavanzika yezvinhu izvi. Inoderedza zvakanyanya nguva yekugadzira uye inoderedza zvakananga mutengo wemuenzaniso weRogers RO4360G2 PCB, zvichibvumira timu dzeR&D kuti dziite nekukurumidza uku dzichichengetedza RF tolerances dzakasimba.
Kudzora Kusagadzikana Kwechokwadi
RO4360G2 PCB prototyping inonyanya kubatsira kana dhizaini ichida mhinduro nekukurumidza nezvekuvakwa kweDk RF ine simba risati rasvika pakushandisa maturusi evhoriyamu. Prototype iyi inofanira kusimbisa mageometry uye ma assembly interfaces ayo akaoma kuchinja gare gare. Highleap Electronics ndiyo mugadziri wePCB uye muunganidzi wekuvaka kwakatsanangurwa pano. Rogers nemazita egiredhi anotsanangurwa anoratidza zvinhu zvakatsanangurwa uye haasi tsananguro yekugadzira zvinhu zveHighleap. Kunyange hazvo kugadzirira maburi kuri nyore, RF etching isingakanganwiri. Dk ye6.15 zvinoreva kuti ma traces anofanira kunge akatetepa zvakanyanya. Kukanganisa kwe1-mil over-etch paDk 6.15 material kuchakonzera kusawirirana kwakanyanya kwe impedance pane pabhodhi reDk 3.5. Vacuum etching lines neLaser Direct Imaging (LDI) zvinosungirwa kuchengetedza trace side walls dzakamira zvakanaka. Kune magadzirirwo achifunga nezvekuvakwa kwakasiyana kwe heat-transfer, TC600 electrical and thermal build review inofanira kushandisa application-specific stackup and cooling interface.
Kudzora Warpage muHybrid RF Stackups
Kuti bhajeti reprojekiti riwedzere kunaka, hazviwanzoitiki kushandisa RO4360G2 pazvikamu zvese zvebhodhi rekutaurirana rakaoma. Pane kudaro, vagadziri vanogadzira ma "hybrid stackups"—vachiisa zvinhu zveRogers pazvikamu 1 ne2 zve "microwave routing", ukuwo vachishandisa High-Tg FR-4 (yakaita seIsola 370HR) inodhura zvishoma pazvikamu zvemagetsi, pasi, uye digital logic.
Zvisinei, kugadzirisa pamwe chete hydrocarbon yakazara neceramic ne epoxy FR-4 kunounza njodzi huru yemakanika: Asymmetric Warpage (Mhedzisiro yeMbatatisi-Chip).
Masisitimu akasiyana eresin ane maGirazi ekuchinja tembiricha (Tg) akasiyana uye anonyungudutsa viscosities. Kana press cycle ikakwira nekukurumidza, FR-4 prepreg inogona kuyerera nepo Rogers prepreg ikaramba yakasimba. Kana bhodhi ratonhora, mwero wekudzikama kwekupisa unokonzera kuti panel ikotama zvine simba. Semugadziri wePCB weChina Rogers RO4360G2 ane ruzivo, Highleap Electronics inodzivirira izvi nekushandisa asymmetric press padding uye maresipi ethermal ramp akagadzirwa zvakanyanya, zvichiita kuti kugadzirwa kwebhodhi risina ma layer akawanda kuite kuti panels dzakatsetseka dzive dzakagadzirira kuungana.
Kushanda pamwe chete neTurnkey RO4360G2 Supplier
Kuwana chigadzirwa chakavimbika che sub-6 GHz kana mmWave inzira ine matanho maviri: kugadzirwa nemazvo kunoteverwa nekuiswa kwezvikamu zvisina dambudziko. Chero zvimedu zve solder pasi pe RF amplifier pad ine simba guru zvinogona kubvisa circuit uye kukonzera kupisa kwakanyanya.
Tinokurudzira zvikuru kuchengetedza zvikamu zvese zviri zviviri pasi pedenga rimwe chete kudzivirira kusawirirana kwemutengesi. Paunenge uchitsvaga mupi weRogers RO4360G2 PCB ane kurasikirwa kwakaderera, iva nechokwadi chekuti ane kugona kusimbisa bhodhi risina chinhu uye majoini ekupedzisira ekusolder. KuHighleap Electronics, sevhisi yedu yakazara yekugadzira PCB yeRogers RO4360G2 inobatanidzwa zvine hungwaru nemitsetse yedu yekugadzira PCBA yepamusoro . Tinoshandisa 3D X-Ray (AXI) inspection kuti tione kuti thermal-grounding coverage yakavharwa sei maererano nehurongwa hwekuongorora uye kuiswa kweRF component chaiyo.
Kunyangwe muchida prototype inokurumidza yekugadzira array itsva kana kugadzirwa kwehuwandu hwezvivakwa zve5G, timu yedu yeinjiniya yakagadzirira kuongorora mafaira enyu eGerber uye zvinodiwa pastackup.
