ITEQ IT-88GMW PCB-1

Radar PCB yemotokari ye76–81 GHz chimiro che electromagnetic, mechanical datum, uye maitiro ekugadzira panguva imwe chete. Patch array, feed network, RFIC launch, ground fence, shield cavity, radome spacing, copper profile, dielectric thickness, uye solder-mask boundary zvese zvinobatanidzwa mukupindura kwekupedzisira kwe antenna. Nekuda kweizvozvo, laminate haigone kubvumidzwa yakazvimirira kubva pa geometry inoishandisa.

ITEQ inoisa IT-88GMW semhando yepamusoro-soro, ine Tg RF laminate uye mhuri ye prepreg ye radar yemotokari refu, yepakati, uye pfupi mubhendi re76–81 GHz, pamwe chete ne mmWave yakasarudzwa, antenna, microwave-link, uye aerospace applications. Ruzivo rweruzhinji rweITEQ runoratidza Dr 3.02 neDf 0.0013 pa10 GHz, Tg 185°C neTMA, T288 inopfuura maminetsi makumi matanhatu, uye maitiro akagadzikana e dielectric nekupisa. Nhamba idzodzo dzinoratidza kirasi yezvinhu; haisi rezenisi yekupinda 3.02 mu 77 GHz model pasina hukama hwakanangana nekuvakwa.

Nei Bhodhi reRadar re77 GHz Risingakwanise Kuonekwa seRF Yakayerwa

Pa77 GHz, wavelength yenzvimbo isina chinhu inenge 3.9 mm uye wavelength inotungamirirwa paPCB inoshanda ipfupi. Kukanganisa kwakakura kusingaonekwe zvakanaka pabhodhi redhijitari kunogona kumiririra chikamu chakakosha chewavelength. Mugumisiro wacho haugumiri pakuchinja kudiki kweimpedance. Inogona kufambisa resonance yepatch, kushandura phase balance mu array, kushandura amplitude inounzwa kune zvinhu zvakasiyana-siyana, kuwedzera cross-polarized radiation, kana kukanganisa beam.

Ndosaka bhodhi reradar risingafaniri kugara nhaka manotsi ekugadzira kubva kubhodhi reRF rine frequency yakaderera. Zviyero zvakakosha zvinosanganisira ukobvu hwe dielectric hwakapedzwa pasi pe antenna, hupamhi hwepamusoro nehwepasi hwemutsara wega wega wekudyisa, slope yecopper sidewall, copper roughness, local resin content, glass-weave orientation, mask registration, cavity height, radome air gap, uye package-to-line transition. Mufananidzo webhodhi unofanirwa kusiyanisa kuti ndeapi eizvi ari ma mechanical dimensions akajairika uye ndeapi ari electrical characteristics.

shanduka Nei 77 GHz iri nyore kunzwisisa Maitiro ekuidzora
Ukobvu hwe dielectric pasi pe radiating layer Inoshandura permittivity inoshanda, line impedance, patch resonance, coupling, uye phase velocity. Omesa ganda rakanyatsogadzirwa kana kuti rakagadziriswa; taura ukobvu hwakapedzwa uye nzira yekuyera nayo; batanidza zvikamu zvepakati neRF coupons.
Geometry yemutyairi wemifananidzo Kucheka kwemadziro uye kupinza pamusoro/pasi pemadziro kunoshandura upamhi hunoshanda uye kugoverwa kwemagetsi. Shandisa impedance artwork compensation, tsanangura huremu hwemhangura uye foil profile, ongorora upamhi hwepamusoro/pasi pane zvinhu zvinomiririrwa.
Kuoma kwemhangura Kushanda kweganda kunotevera pamusoro pemhangura; kuomarara kunowedzera kurasikirwa neconductor uye kunogona kuchinja chimiro. Taura VLP yakatenderwa kana foil yakaenzana neprofile inoyerwa uye kuvakwa kwemutengesi, kwete chete chirevo chekuti "low profile."
Kurukwa kwegirazi uye kugoverwa kweresin Local Dk anisotropy inogona kugadzira kusawirirana kwechikamu uye kusiyana kwechinhu kusvika kune chimwe chinhu. Ongorora maitiro egirazi, nzira yekutsvedza, zviri mukati me resin, sarudzo dzemagirazi akapararira, uye nzira yekutsvedza mapaneru; simbisa chivakwa chakaburitswa.
Chifukidzo cheSolder nengano Kuisa magetsi pamusoro pemupendero we feed kana antenna kunogona kudzima chimiro. Gadzira nzira dzakajeka dzekuchengetedza data pazvigamba, ma couplers, ma resonators, ma launcher, uye ma calibration; kudzora kunyoresa.
Nhare, gomba, uye nzvimbo yepakati pe radome Zvinhu zvesimbi ne dielectric zviri pedyo ne antenna zvinoshandura mamiriro emuganhu nemwaranzi. Tevedzera imba chaiyo uye radome; tsanangura madhatamu emakanika uye torara yekutora; simbisa mamodule akaunganidzwa.

Kushivirira kugoverwa kwekuita, kwete kugona kwakajairika

Mugadziri anogona kukwanisa kugadzira chidimbu chakamanikana kana kuti dielectric yakatetepa, asi dhizaini yacho inogona kusaburitswa kana shanduko inobvumidzwa ikashandisa antenna-frequency kana phase budget. Chikwata chemainjiniya chinofanira kugovera resonance shift inobvumidzwa, insertion-loss change, uye phase error pakati pezvinhu, etch, lamination, assembly, housing, uye tembiricha. Ndipo chete panogona kushandurwa system targets kuita shop-floor controls.

Semuenzaniso, kushivirira kureba kwechigamba hakufanirwe kusarudzwa kubva patafura yakajairwa yehupamhi hwemutsara. Inofanira kubva mukuongorora kwekunzwa kwemagetsi: kutsvaira zviyero zvechigamba, ukobvu hwe dielectric, Dk, ukobvu hwemhangura, uye muganhu wemasiki; ziva mavariables anofambisa frequency yepakati kana beam zvakanyanya; wobva waisa miganhu yekugadzira inoshanda kune mavariables iwayo. Nzira imwecheteyo inofanira kushandiswa kune branch-line dividers, series feeds, corporate feeds, transitions, uye maficha anoenderana.

Tanga neRadar Module Architecture

Sarudzo yezvinhu inochinja nekugadzirwa kweradar. Module ine chip imwe chete ine maantenna papakeji ine basa rakasiyana rePCB kubva pabhodhi-level patch array inopihwa neRFIC. Saizvozvowo, cascaded multi-chip array, bhodhi reantenna rakasiyana rakabatana nedhijitari control board, uye dhizaini yeantenna-in-package zvinogadzira zvinodiwa zvakasiyana pahuwandu hwelayer, hybrid bonding, connector launches, thermal paths, uye calibration.

Magadzirirwo emodule Njodzi huru dzePCB Kutarisa pakusarudza IT-88GMW
Chigamba chebhodhi-level chine RFIC paPCB imwecheteyo Kushivirira kwe dielectric ye antenna, RFIC launch, feed-network phase balance, shield/radome coupling. Shandisa antenna chaiyo sechigadzirwa; dzora kuchengetedza masiki, foil profile, kufamba kwelamination, uye datums dzekuunganidza.
Akasiyana antenna uye mabhodhi ekugadzirisa Kutangisa bhodhi kubva kune rimwe bhodhi kuenda kune rimwe bhodhi kana kuti coax, kugadzirisa michina, kudzokorora kwekubatanidza, kuenderera mberi kwenzira yekudzoka.

Ngatiite ongororo yeDFM/DFA kwauri tobva tadzoka kwauri nemushumo. Unogona kurodha mafaira ako zvakachengeteka kuburikidza newebhusaiti yedu. Tinoda ruzivo runotevera kuti tikupe mutengo:

    • Gerber, ODB++, kana .pcb, spec.
    • BOM rondedzero kana iwe uchida kusangana
    • uwandu
    • Kuchinja nguva
Pamusoro pekugadzira PCB, isu tinopa huwandu hwakakwana hwemagetsi masevhisi, anosanganisira PCB dhizaini, PCBA, uye turnkey mhinduro. Kunyangwe iwe uchida rubatsiro neprototyping, dhizaini yekusimbisa, kutsvagisa chikamu, kana kugadzirwa kwakawanda, isu tinopa yekupedzisira-kusvika-kumagumo rutsigiro kuti uve nechokwadi chekubudirira kweprojekiti yako.

Kune masevhisi ePCBA, ndapota ipa BOM yako (Bhiri reZvinhu) uye chero mirairo yegungano. Isu tinopawo DFM/DFA ongororo yekukwidziridza zvigadziriso zvako zvekugadzira uye kusangana, kuve nechokwadi chekuita kwakatsetseka kwekugadzira.






    Quick Note: Chikwata chedu chinokutumira email munguva pfupi mushure mekutumira. Kuti uve nechokwadi chekuti wagamuchira mhinduro yedu, tinokurudzira kutarisa SPAM/JUNK FOLDER yako kana usingaone meseji yedu muinbox yako.
