Zvinogona kukodzera panodiwa nebhajeti yekurasikirwa, asi mutengo unofanirwa kuratidza gadziriro chaiyo yegomba, nzira yekuisa lamination/bonding, kuvaka mhangura uye hurongwa hwekuongorora.

3. Chii Chinoita Kuti Kugadzira Rogers PCB Kudhure Zvikuru

Kupfuura mutengo wezvinhu zvakagadzirwa, matanho akawanda ekugadzira anowedzera mutengo wakanangana neRogers PCBs:

Kushandiswa kwezvishandiso zvekuboorera. Malaminate akazadzwa neceramic eRogers (RO4000, RO3000) ane zvidimbu zveceramic zvakasimba zvinokurumidzisa kupera kwezvishandiso zvekuboorera. Zvishandiso zvakaoma uye kugadzirwa kwezvinhu zvinogona kuwedzera kupera kwezvishandiso uye kukanganisa kufambira mberi kwekuboorera. Hupenyu chaihwo hwezvishandiso hunoenderana nekuvakwa kwebhodhi, huwandu hwemaburi uye marongero ekushanda, saka mutengo wemutengesi unofanirwa kuratidza hurongwa hwekuboorera hwakaburitswa pane kuwedzera hupenyu hwezvishandiso.

Kusviba kweplasma. Zvinhu zveRogers zvakagadzirwa nePTFE (RO3000, RT/duroid) hazvipindure nemakemikari e desmear akajairwa e permanganate. Kusviba kweplasma uchishandisa musanganiswa wegasi reCF₄/O₂ kunodiwa kuchenesa madziro emaburi uye kuita kuti pamusoro payo pave ne copper plating. Haasi mafekitori ese ePCB ane kugona kwe plasma desmear - ayo anobhadharisa mari yakawanda padanho rekuita. Zvinhu zveRO4000 series zvinogona kushandisa standard chemical desmear, zvichidzivirira cost adder iyi.

Saizi yemapaneru uye mashandisirwo awo. Mapaneru eRogers anowanikwa muhukuru hushoma hwemapaneru pane FR4 (paneru yakajairika yeRogers: 12 × 18 inches kana 18 × 24 inches, zvichienzaniswa neFR4 inowanikwa muhukuru hunenge hwese). Kana saizi yebhodhi rako isingagare zvakanaka pahukuru hwepaneru yeRogers huripo, marara ezvinhu anowedzera uye mutengo wepabhodhi rimwe nerimwe unokwira. Kugadzirisa mapaneru ebhodhi ehukuru hwepaneru yeRogers kunogona kuderedza marara ne10–20%.

Nguva yekutora zvinhu zvinotengeswa neRogers inokanganiswa nemutengo. Standard FR4 inowanikwa nevanhu vakawanda. Zvinhu zveRogers, kunyanya magiredhi ePTFE uye ukobvu hushoma, zvinogona kuda nguva yekuwedzera kutenga kubva kuRogers Corporation kana kune vanoitengesa. Maodha ekukurumidza anodhura mitengo yepamusoro. Mafekitori anochengetedza kuwanikwa kwezvinhu zveRogers anogona kutaura nguva pfupi yekutora zvinhu pasina muripo wekuwedzera - ichi chinhu chakakosha pakusarudza mugadziri weRogers PCB.

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

4. Maitiro Ekuderedza Mutengo weRogers PCB: 7 nzira dzinoshanda dzekutonga mitengo

Nzira 1: Shandisa Rogers FR4 hybrid stackup. Isa Rogers chete paRF signal layers uye FR4 papower, ground, uye digital layers. Iyi ndiyo imwe sarudzo inogona kushandiswa kudzora mutengo — kuchengetedza zvinhu ne30–50% pabhodhi rine layers 6. Ona gwara redu reRogers FR4 hybrid PCB kuti uwane rumwe ruzivo nezve stackup design.

Nzira yechipiri: Sarudza RO4000 pane RO3000/RT/duroid kana frequency yako ichibvumira. Kana frequency yako yekushanda iri pasi pe15–20 GHz, RO4350B kana RO4003C ingangosangana nebhajeti yako yekurasikirwa nechikamu chidiki chemutengo wezvimwe zvinoshandiswa nePTFE. Shandisa insertion loss simulation uchienzanisa zvinhu pafrequency yako usati wasarudza sarudzo inodhura zvakanyanya.

Nzira 3: Gadzirisa mashandisirwo epaneru. Shanda nemugadziri wePCB yako kuti mugadzire mapaneru ebhodhi renyu kuti rikwane zvakanyanya pahukuru hwepaneru reRogers riripo. Kutenderedza marongerwo ebhodhi 90° kana kugadzirisa miganhu yebhodhi ne 1–2 mm dzimwe nguva kunogona kukwana koramu kana mutsetse wepaneru, zvichideredza mutengo wezvinhu pabhodhi rega rega ne 10–20%.

Nzira 4: Sarudza ukobvu hwakajairika hweRogers. Rogers ine ukobvu hwakasiyana hwepakati hwakakura (10, 20, 30, 60 mil yeRO4350B). Ukobvu husina kujairika hunoda maodha elamineti akagadzirwa nemaoko ane nguva yakareba yekutungamira uye huwandu hwakanyanya. Gadzira stackup yako zvichienderana neukobvu hwakajairika huripo kudzivirira muripo wezvinhu zvakagadzirwa nemaoko.

Nzira 5: Deredza huwandu hwema layer. Ma layer mashoma zvinoreva kuti zvinhu zveRogers hazvina zvakawanda. Ongorora kana hybrid ine layer 4 inogona kutsiva dhizaini yeRogers ine layer 6 nekubatanidza pasi nemagetsi uye kusimbisa nzira yedhijitari paFR4 layers.

Nzira 6: Kubatanidza maodha. Kugadzirwa kweRogers PCB kune mitengo yakatarwa (kutenga zvinhu, kugadzira lamination, impedance test fixture). Huwandu hwemaodha makuru hunoderedza mitengo iyi. Kana zvaunoda pagore zvichitsigira, tauriranai nezvemaodha ekota yega yega pane kutenga zvinhu zvidiki kakawanda.

Nzira 7: Batana nefekitori inochengeta zvinhu zveRogers. Mafekitori anochengetedza zvinhu zveRogers anodzivisa nguva yekutenga zvinhu zveRogers kwemavhiki mana kusvika masere uye mari yekuwedzera inosanganisirwa. Kutenga zvinhu zvakawanda kunogona kuvandudza mitengo yezvinhu, asi mutengo chaiwo unoenderana negiredhi rakatenderwa, kuvakwa, huwandu, uye nzira iripo yekugovera zvinhu.

5. Rogers PCB Mitengo Mienzaniso Nekushandisa

Aya ndiwo marudzi anoratidza - mitengo chaiyo inoenderana nehuremu hwemhangura, kupera kwenzvimbo, zvinodiwa zve impedance, huwandu hwemaburi, uye mugadziri. Chinhu chakakosha: ma hybrid stackups anogara achipa mutengo wakaderera payuniti yega yega pahuwandu hwemavhoriyamu kunze kwemabhodhi madiki, akareruka uko kuvaka kweRogers 2-layer kwatove kukwikwidzana nemari. Highleap inoparadzanisa kuvaka kuita zvinhu zveinjiniya, zvekushandisa, zvekugadzira, zvekuongorora uye zvekuunganidza pakuongorora mutengo. Kuderedza mitengo kunoshanda zvakanyanya kana kuchidzivirira ma RF-critical layers uye kubvisa kuomarara kusingakoshi munzvimbo dzisiri dzengozi. Kukosha kwepfuma chaiyo yezvinhu kunofanirwa kuongororwa zvichienderana nemagwaro emutengesi aripo egiredhi rakatarwa uye kuvaka.

6. Tora mutengo weRogers PCB kubva kuHighleap

Kuwanikwa kweRO4350B, RO4003C, RO4835, uye ukobvu hwakajairika kunosimbiswa paRFQ; nguva yekutungamirwa kwezvinhu inosiyana zvichienderana negiredhi, ukobvu, mhangura, uye huwandu hwekuodha. Zvakanakira mitengo yeRogers PCB:

Kutsvaga zvinhu. Kutsvaga zvinhu kuburikidza nenzira dzakanyorwa dzekupa zvinhu zvegiredhi rakatarwa. Mitengo yezvinhu zvinoenderana nehuwandu inotumirwa kune vatengi. Macores akafanana uye bondply muzvinhu zvekutanga kugadzirwa nekukurumidza. Kutsvaga zvinhu zvine mvumo kunovimbisa kuti zvinhu zveRogers zvechokwadi - hapana njodzi ye laminate yenhema kana isina kutsanangurwa.

Kugadziriswa kwemhando yepamusoro ye "hybrid stackup". Chikwata chedu chemainjiniya chinoongorora dhizaini yako uye chinokurudzira musanganiswa wezvinhu usingadhuri zvakanyanya - kuona zvikamu apo FR4 inogona kutsiva Rogers pasina kuderedza mashandiro eRF. Ongororo iyi inopihwa padanho rekutaura, usati wazvipira kudhizaini.

Kugadziriswa kwekushandiswa kwemapaneru. Tinoongorora sarudzo dzemapaneru ebhodhi rako tichienzanisa nehukuru hwemapaneru eRogers aripo uye tinokurudzira kugadziriswa kwemagadzirirwo ayo anowedzera kugona kwezvinhu.

Matanho emitengo yehuwandu. Muenzaniso (5–50 pcs), matanho ekugadzira asati agadzirwa (50–500 pcs), uye matanho emitengo ekugadzira (500+) ane zvidzikiso zvehuwandu. Zvibvumirano zvekutenga zvinhu zvebhuraketi zviripo zvekugadzira zvakare. Kune dhizaini isina kusimbiswa, Rogers prototyping isati yatengwa inogona kugadzirisa njodzi dzekuvaka zvisati zvafungidzirwa kuti mitengo yehuwandu yapera.

Kumbira mutengo weRogers PCB — sanganisira rudzi rwezvinhu zveRogers, huwandu hwezvikamu, saizi yebhodhi, zvinodiwa zve impedance, huwandu, uye zuva rekutumira. Tinodzosera kupatsanurwa kwakadzama kwemitengo mukati memaawa makumi maviri nemana. Kuti muone mutengo wakafanana, chengetai zvirevo zvakafanana pakati pevatengesi. RFQ inofanira kutaura zviyero, stackup, copper, finish, hole technology, zvinodiwa zve impedance, huwandu uye kuyedzwa kuitira kuti mitengo yakaderera isavanze chivakwa chakasiyana.
