Kugadzirwa kwePCB yeRO4725JXR
Kugadzirwa kwePIM shoma kunodarika kurira kwelaminate. Nzvimbo dzemhangura, maplating, kuchenesa, maconnector interfaces, mechanical hardware uye mabatirwo azvo zvese zvinofanirwa kudzorwa kuitira kuti bhodhi reantenna rapera risaise manyuko ekudzivirira anopinda mukati memodulation.
Mufananidzo 1. Kugadzirwa kweRogers RO4725JXR PCB
Kugadzirwa kwePCB yeRO4725JXR yemabhodhi eantenna e-low-PIM kunoenderana nekuchengetedza nzvimbo dzeRF uye ma interfaces emakanika akafanana. PIM yakaderera imhando yekupedzwa kwekubatanidza, saka kusarudzwa kwelaminate, geometry yemhangura, kupedzisa, kuchena uye ma interfaces ekubatanidza zvinofanirwa kushanda pamwe chete. Kugadzirwa kwePCB yeRogers RO4725JXR kunosarudzwa kumabhodhi eantenna uko PIM yakaderera, kufanana kwemapaneru, uye maitiro eRF anodzokororwa zvakakosha. RO4725JXR ilaminate yeDk 2.55 antenna-grade inoshandiswa mu base-station, distributed antenna, uye array antenna designs. Rogers documentation inoisa RO4725JXR yekuderedza PIM uye kurasikirwa kwakaderera kwekuisa, nekushanda kwePIM kwakaderera kuri nani pane -160 dBc pasi pemamiriro ekuyedza akataurwa. Highleap Electronics inoongorora laminate callout, copper system, panel layout, plating, solder finish, connector areas, uye inspection records usati waburitswa.
Zviri Mukati
Chimiro chezvinhu: Peji rino rine chekuita nekugadzirwa kwePCB uchishandisa zvinhu zvakatarwa zveRogers. Highleap Electronics inogadzira bhodhi rakapedzwa nePCBA; kugadzirwa kwelaminate uye kutengeswa kwezvinhu zviri kunze kwechikamu chedu chebasa.
Kana RO4725JXR iriyo Antena PCB Material Yakakodzera
RO4725JXR inoshandiswa kuma antenna boards anoda kurasikirwa kwakaderera, maitiro e dielectric akagadzikana, kugadziriswa kusina lead, uye kudzora kungwarira kwe intermodulation. Inonyanya kukosha kune ma base-station antennas, distributed antenna systems, RF feed networks, uye outdoor communication hardware uko kakukanganisika kadiki munzira iripo kunogona kukanganisa mashandiro ekupedzisira eRF.
Sarudzo yezvinhu inofanira kuenderana nezvinodiwa zveantenna. Kana chigadzirwa chichaedzwa kuti chionekwe sePIM, dhizaini yePCB neRFQ zvinofanirwa kuona chinangwa, connector interface, surface finish, copper features, cleansing requirements, uye kana mutengesi ari iye ane basa rekubatanidza. Izvi zvakakosha kupfuura kungotumidza laminate chete. Kana antenna material shortlist ichisanganisirawo RO4533, RO4533 antenna laminate comparisons inofanira kushandisa frequency model yakasiyana uye board specifications.
PIM yakaderera inoenderana nekuchena kwekugadzira, kwete zita reLaminate chete
Kune mabhodhi eantenna, laminate ine PIM shoma ndiyo chete nzvimbo yekutanga. Passive intermodulation inogona kukanganiswa nekusagadzikana kudiki uye kusapindirana kwesimbi isina kukwana, kusanganisira copper plating isingaenderane, nzvimbo dzakasvibiswa dzekubatana, rough connector pads, crackled solder joints, burrs, loose hardware, kana uneven surface finish. Ndosaka kugadzirwa kweRO4725JXR kuchifanira kubatwa senzira yeRF inodzorwa pane kurongeka kwePCB ine layer mbiri. Kana AD250C yakanyoreswawo se antenna, kuvaka kweAD250C low-PIM antenna kunoda zvinodiwa zvayo zve dielectric geometry, copper uye connector.
Chinhu chakakosha pakugadzirwa kweRF current path chinofanira kunge chiri nzira yeRF current. Highleap inotarisa maficha emhangura, maburi akaiswa plated, ma connector launch pads, ma solder mask clearances, nzira dzemupendero, mapaneru ekubata, nzvimbo dze connector soldering, uye chero hardware interface inogona kuva nonlinear contact. Burr diki pamucheto, launch pad yakakwenywa, kana residue yakatenderedza connector land zvingasaita seyakakomba mukutarisa kwakajairika, asi zvinogona kukosha kana antenna yakapedzwa yaongororwa yePIM.
Kana antenna iri chikamu che base-station, DAS, repeater, kana outdoor RF unit, RFQ inofanira kutaura chinangwa chePIM, rudzi rweconnector, test frequency, power level, acceptance method, uye kana Highleap iri kutaura nezvekugadzirwa kwePCB chete kana kuti PCB assembly . Ruzivo urwu runoshandura mashandisirwo anoita mutengesi kuchenesa, kurongedza, kudzivirira connector pad, soldering, uye outgoing inspection.
- Taura chinangwa chePIM chinodiwa uye nzira yekuyedza usati wataura kuti chigadzirwa chapedzwa chichaedzwa riini nePIM.
- Dzivirira nzvimbo dzinotanga kusunganidzwa pamwe nenzvimbo dzinosangana nechinhu kubva pakukwenya, masara, maburi, uye kubata zvisina kunaka.
- Ongorora midziyo yekubatanidza uye majoini ekugadzira pamwe chete nemaitiro ekugadzira bhodhi risina chinhu, kwete mushure mekuendeswa kwePCB.
Zvimiro zveRO4725JXR zvine chekuita nekugadzirwa kwePIM shoma

Manufacturing Process Controls
Nzira yekushanda inofanira kusarudzwa zvinhu zvisati zvaburitswa kuti zvigadzirwe. Zvakajairika zvinodzora zvinosanganisira kusimbiswa kwezvinhu, kuongorora kwemukati mechikamu, kuongorora lamination, mhando yekuboorera, kugadzirira maburi pamadziro, copper plating, solder mask registration, surface finish, routing accuracy, electrical test, uye final inspection. Highleap inoongorora maficha eantenna, copper definition, surface finish uye drilling ichifunga nezvezvinodiwa zve PIM yakaderera. Kana bvunzo ye PIM ichidikanwa, nzira yekugamuchira inofanira kuenderana nehardware yakaunganidzwa kwete bhodhi chete. Hunhu chaihwo hwezvinhu hunofanira kuongororwa zvichienderana nemagwaro emutengesi aripo iye zvino egiredhi rakatarwa uye kuvaka.
Pakugadzirisa PIM shoma zvakare, chengetedza kupedzisa kwenzvimbo kwakatenderwa, nzira yekuchenesa, kuvakwa kwemhangura, interface yekubatanidza uye zvinyorwa zvezvinhu zvinopinda. Kuchinja kwemaitiro kunofanirwa kuongororwa zvichienderana nenzira imwecheteyo yekukodzera RF pane kugamuchirwa kwebhodhi chete.
RFQ Package uye Zvinyorwa zveKugadzira
Mashandisirwo akajairika anosanganisira ma antenna e base-station, phased arrays, DAS hardware, RF feed networks, low-PIM passive boards, uye antenna subassemblies uko shanduko diki dzemaitiro dzinogona kukanganisa mashandiro eRF esystem.
Tumira mafaira eGerber, data rekuboorera, bhodhi, ukobvu hweRO4725JXR, huremu hwemhangura, kupedzisa kwenzvimbo, manotsi emasiki ekusolder, zvinodiwa papaneru yeantenna, ruzivo rwekubatanidza, zvinotarisirwa nePIM, huwandu, uye purogiramu yekugadzira.
Kune RO4725JXR low-PIM builds, humbowo hunobatsira hunogona kusanganisira kuteverwa kwezvinhu, zvinyorwa zvepamusoro-soro, kudzora kuchena, kuongorora kwemakanika uye nzira yekuyedza yeRF inoshandiswa kugamuchirwa kwelow-PIM. Magwaro acho anofanira kufukidza mamiriro ebhodhi-ku-connector uye simbi-interface anogona kukanganisa kubatanidzwa kwapera. Kune RFQ, sanganisira antenna drawing, frequency band, PIM target, stackup, finish, connector details uye huwandu. Izvi zvinopa mugadziri muganhu wakajeka wekugadzira uye wekuyedza.
