Mutengesi weTaconic RF-60A Antenna PCB | Turnkey Assembly

Kana tichigadzira mafirita ema microwave, ma amplifiers emagetsi, uye ma network e antenna feed ane phased array, zvikwata zve hardware zvinotarisana nebhajeti rakasimba rekuchengetedza masaini. Ma laminates eFR-4 akajairika anounza kurasikirwa kusingagamuchirwi kwekuisa uye kuchinja kwechikamu pama frequency akakwira. Kuti zviratidzo zvirambe zvakajeka, mainjiniya anotsanangura ma substrates akavakirwa paPTFE seTaconic RF-60A. Ne dielectric constant ye6.15, inopa chiyero chakanaka pakati pe circuit miniaturization uye kushanda kwemagetsi kusingarasikirwe zvakanyanya.

Zvisinei, kusarudza zvinhu zvakakodzera ingori danho rekutanga. Kushanda kwebhodhi rako kunoenderana nekugona kwefekitori kudzora magadzirirwo emagetsi, mhando yekuboorera, uye kuvimbika kweplating pane Teflon substrate isina makemikari. Kuwana mugadziri wePCB weChina Taconic RF-60A anokwanisa zvinoreva kushanda pamwe chete nekambani yekugadzira PTFE PCB inodzivirira RF yako kubva pakurongeka kwayo kwekutanga kuburikidza nekugadzirwa kwakawanda. KuHighleap Electronics, tinobatanidza musiyano uripo pakati pekufananidzira kwemagetsi nekugadzirwa kwemuviri.

Tumirai RF-60A Project yenyu kuti muiongorore paDFM

Magadzirirwo ehunyanzvi eRF-60A Microwave Printed Circuit Board

Bhodhi reRF-60A rakadhindwa mu microwave rakavakirwa paPTFE yakagadzirwa negirazi rakasimbiswa yakagadzirwa zvakanangana neRF applications dzinoshanda zvakanaka. Kana mainjiniya vakasarudza zvinhu izvi kubva mu microwave dielectric materials portfolio yedu yepamusoro , vanovimba nedatasheet metrics chaiyo kuti vave nechokwadi chekugadzikana kwechikamu uye kuvimbika kwekupisa.

• Dielectric Constant (Dk): 6.15 ± 0.15 (pa10 GHz). Kukwidziridzwa uku kweDk kunobvumira kuderedzwa kwakanyanya kwecircuit zvichienzaniswa nezvinhu zvakajairwa zveDk 3.5, zvichiita kuti ive yakakodzera ma compact RF modules.
• Dissipation Factor (Df): 0.0028 (pa10 GHz). Inoita kuti zvinhu zve microwave zvisashande zvakanaka uye network dzekudya zvisashande zvakanaka.
• Thermal Conductivity: 0.41 W/mK. Yakagadzirirwa kubata zvinodiwa zvekuparadza kupisa kwema amplifiers eRF anoiswa pamusoro anoshandiswa mu misangano yakaoma yebhodhi renhare.
• Kunyura kwemvura: 0.02%. Mvura ine dielectric constant inovhiringidza zvakanyanya. Mwero uyu wekudzikira kwekunyudzwa kwemvura unovimbisa kushanda kwakasimba kweimpedance kunyangwe munzvimbo dzakavharirwa antenna dzekunze.

Zvipingamupinyi muRF-60A Low Loss Board Production

Kugadzira Taconic RF-60A high frequency PCB yakasiyana zvikuru nekugadzira standard rigid FR-4. Muumbirwo wePTFE wegirazi rakarukwa wechinhu ichi unoramba kushandiswa kwemakemikari kwakajairika. Kuti uve nechokwadi chekuti bhodhi rako rinoenderana neHFSS kana CST simulations yako, fekitori ine hunyanzvi inofanira kugona matanho matatu akakosha ekugadzira.

1. Kunyora Trace uye Kunyatsoongorora LDI

Nekuti Dk yeRF-60A iri 6.15, ma RF traces ako e50-ohm achava matete zvakanyanya pane ari paDk substrate iri pasi. Bhati remakemikoro rinocheka zviri nyore rinocheka mitsetse iyi isingaonekwe, richidya mativi emhangura. Izvi zvinogadzira trapezoidal trace profile iyo inoshandura hunhu hwe impedance uye inokonzera kuratidzwa kwakanyanya kwechiratidzo.

Kuti tidzivise izvi panguva yekugadzira RF-60A low loss board, Highleap inoshandisa Laser Direct Imaging (LDI) chete pane kushandisa masks efirimu echinyakare panguva yekugadzira PCB yedu ye millimeter-wave . LDI inovimbisa mativi etrace side akatarwa zvakakwana ane ±10%. Uyezve, tinokurudzira zvikuru vagadziri kuti vatsanangure 0.5 oz (18 μm) kana 1 oz (35 μm) base copper. Heavy copper (2 oz kana kupfuura) inoda makemikari ekucheka kwenguva refu ayo asingadzivisiki anobvisa ma microwave traces akatetepa.

2. PTFE Metallization uye Plasma Desmear

Teflon haina makemikari uye haipindi mvura mumuviri (inodzinga mvura). Kana fekitari ikaboora bhodhi reRF-60A yorifambisa nepakati petambo yesimbi isina electroless copper, mhangura yemvura inobuda nepakati uye inobviswa pamadziro. Izvi zvinotungamira kumatanho akavhurika anouraya kana bhodhi rikabatwa nekupisa panguva yeSMT reflow.

Kubudirira kwekugadzira Taconic RF-60A circuit board kunoda kushanda kwakasimba kwefluoropolymer. Tisati taisa plating, tinoisa mapaneru akaboorwa mukamuri re plasma re vacuum, tichiisa ioni musanganiswa chaiwo weCF4 neOxygen gases. Iyi plasma ine simba guru inorova PTFE, ichiisa madziro emaburi mu microwave kuti igadzire nzvimbo inonyungudika. Izvi zvinovimbisa kuti palladium catalyst uye copper plating inotevera zvinonamira zvakachengeteka ku via barrel, zvichizadzisa IPC Class 3 manufacturing standards.

3. Kuyera mativi ekunyora akawanda

Kunyangwe fiberglass yakarukwa ichisimbiswa, PTFE polymer inoramba iine kushushikana kukuru kwemukati memuchina kubva mukuita kwayo kwekunamira pafekitori yezvinhu zvakagadziriswa. Munguva yekugadzira bhodhi rakagadzirwa nehupamhi hwepamusoro , patinocheka mapuraneti emhangura akaremara kuti tigadzire circuitry yako, kushushikana uku kwakavakirwa mukati kunoburitswa zvine simba, zvichiita kuti zvinhu zviderere zvishoma nezvishoma.

Pakuenzanisa ma ultra-fine RF traces pakati pe 8 kana 10 layers, kusabhadharwa kunokonzera shrinkage kuburikidza nekubuda kwe breakouts uye kusanyoresa zvakanaka kwe layers. Mainjiniya edu eCAM anogadzirisa izvi nekumhanyisa first-article test panels kuti averenge chaiwo X/Y dimensional scaling factors. Aya ma compensation ratios anoshandiswa zvakananga kuGerber artwork yako usati wasangana neLDI, zvichiita kuti layer-to-layer alignment ive yakakwana.

MaHybrid Stackups: Kuderedza Mutengo Wako weTaconic RF-60A PCB Fabrication

Ma PTFE laminates ane ma frequency akawandisa anomiririra chikamu chikuru chemari yako yeBOM. Kushandisa RF-60A pachikamu chimwe nechimwe chebhodhi rine ma layer masere kutambisa mari yako yekutenga kana chikamu chepamusoro chete chiine chiratidzo che microwave.

Kuti tiverenge mitengo ye hybrid RF stackup yenyu uye kuderedza zvakanyanya mutengo weTaconic RF-60A PCB yekugadzira, isu tine hunyanzvi mu asymmetric hybrid stackup engineering. Isu tinoshandisa RF-60A yezvinhu zvinodhura chete kune zvakakosha zvekunze, uye tinozvibatanidza neTg FR-4 inodhura, ine mutengo wakaderera uye ine simba repamusoro kune yako yemukati digital logic uye power planes. Nekushandisa maresipi e thermal press akagadzirwa, anononoka-ramp, tinobatanidza zvinhu izvi zvakasiyana zvakakwana pasina kukonzera asymmetric warpage.

Nguva dzekutungamira dzeTaconic RF-60A Microwave PCB Prototype

Nguva yekutenga zvinhu zvitsva inokosha zvikuru muchikamu chekutaurirana. Kumirira kwemavhiki kuti fekitari iwane zvinhu zvitsva kubva kune vanotenga zvinhu zvekunze kwenyika hazvigamuchirwi. Tine ongororo yezvakagadzirwa zvePTFE laminates dzinozivikanwa, zvichitibvumira kutanga prototype yako yeTaconic RF-60A microwave PCB mushure mekunge DFM yabvumidza.

Hatisiyi mashandiro eRF yako kuti aitike netsaona. Isu tinoenzanisa upamhi hwetrace yako nefactory etching factors yedu chaiyo tichishandisa ma microwave etching protocols uye Polar Instruments impedance calculator. Mushure mekugadzira, tinoedza physical impedance coupons tichishandisa Time Domain Reflectometry (TDR) equipment. Batch yega yega yekugadzira inotumirwa neTDR test report yakazara, ichipa humbowo hwakanyorwa kuti mabhodhi ako e-high-Dk anosangana nezvinodiwa zvako zve50-ohm.

Kuungana kweTurnkey kubva kuTaconic RF-60A RF PCB Factory

Kubvisa mabhodhi ePTFE anonzwa kubva kumugadziri webhodhi asina chinhu kuenda kune imwe imba yekusangana kunounza njodzi huru dzekutakura zvinhu. Kubata mavanga pamutsetse weRF unonyanya kukosha kunogona kuchinja nyore nyore impedance, zvichiparadza mashandiro emodule.

Kuti vasanyanya kutenderedza vatengesi, Highleap Electronics inoshanda sefekitori yakazara yeTaconic RF-60A RF PCB uye semutengesi weTaconic RF-60A antenna PCB. Isu tinoshandura purojekiti yenyu kubva pamitsetse yedu isina bhodhi kuenda kune yedu turnkey surface mount technology (SMT) lines zviri nyore.

Nekuchengetedza purojekiti yenyu pasi pedenga rimwe chete, tinogadzira ma profiles e thermal reflow akagadzirirwa anoremekedza substrate yePTFE uye tinoshandisa 3D X-Ray (AXI) inspection kuti tive nechokwadi chekuti thermal ground haina void pasi pezvinhu zvine simba guru reRF. Bata timu yedu yeinjiniya nhasi kuti utumire mafaira ako eGerber neBOM.
