Arlon 25N PCB Kugadzira | Mugadziri weMicrowave Board

Pakugadzira mashandisirwo ema microwave, ma antenna ane phased-array, uye nzira dzekugamuchira ruzha rushoma, mainjiniya ehardware vanoda substrate inopa kurasikirwa kwakaderera zvakanyanya uye kugadzikana kwechikamu kwakanyanya. Arlon 25N sisitimu yepamusoro yakarukwa yegirazi-yakasimbiswa, ine cross-linked thermoset resin yakagadzirirwa zvakananga nzvimbo idzi dzinoda RF. Nekupa kushanda kwepamusoro kwekupisa uye kwemakanika zvichienzaniswa nePTFE yechinyakare, inovhara musiyano uripo pakati pekunyatsojeka kwemagetsi uye kugona kugadzirwa kwakavimbika.

Nekuti inoshanda zvakafanana neFR-4 yakajairwa uku ichipa hutachiona hwemasaini e microwave, Arlon 25N ndiyo sarudzo yepamusoro yekugadzira RF yakawanda uye inodhura zvishoma. Semugadziri wePCB weArlon 25N wekuChina ane ruzivo , Highleap Electronics yakagadzira gwara iri kuti ikubatsire kugadzirisa mitengo yako yekuunganidza zvinhu, kukurumidzisa nguva yako yekutungamira, uye kuve nechokwadi chekuti zvigadzirwa zvako zve microwave zvakabatana zvakanaka.

Magadzirirwo ehunyanzvi eArlon 25N Microwave Laminate

Kusiyana nezvinhu zvine simba repamusoro-soro zvinongoshandiswa chete pakuita kuti zvinhu zvisashande zvakanaka (seTaconic CER-10 ), Arlon 25N yakagadzirwa kuti iite kuti zviratidzo zvishande zvakanaka. Nekuti i thermoset resin, haikanganisike ne "cold flow" kana expansion yeZ-axis thermal inowanzo shandiswa neTeflon laminates yakachena.

Kana mainjiniya edu eCAM akaongorora dhizaini yenyu, tinogadzirisa mitsetse yedu yekugadzira zvichibva pane izvi zvakakosha zvedatasheet metrics:

• Dielectric Constant (Dk): 3.28 ± 0.05 (pa10 GHz). Iyi DD yakasimba zvikuru inowanzoongororwa nemainjiniya pamwe chete nemidziyo yemuchadenga yakaita se laminate ine PTFE yakaderera-kurasikirwa ye antenna feeds dzakaoma.
• Dissipation Factor (Df): 0.0025 (pa10 GHz). Inovimbisa kurasikirwa kwakanyanya kwekuisa, ichichengetedza simba remasaini mumagetsi ekudzivirira ruzha rwakaderera (LNA).
• Glass Transition Temperature (Tg): >250°C. Kusimba kwekupisa uku kwakanyanya kunoita kuti bhodhi rikwanise kurarama nekufamba kwenguva refu kweSMT pasina lead pasina kuchenesa kana kusimudza mapedhi.

Kushivirira Kwekunyorwa Kwemavara Madiki Kwemagadzirirwo Akawanda

Chipingamupinyi chikuru chekugadzirwa kwebhodhi rema microwave rakadhindwa kudzora upamhi hwema trace. Kunyangwe kuchinja kwema microscopic mu upamhi hwema trace, ukobvu hwemhangura, kana kuchekwa kwe etch zvinochinja zvakanyanya hunhu hwe impedance. Bhati rema chemical etching rinobvisa mitsetse iyi zviri nyore, zvichiita kuti trapezoidal trace profile inokonzera kuratidzwa kwakanyanya kwechiratidzo.

Kuti tive nechokwadi chekuti software yenyu yeRF simulation inoshanda zvakanaka, tinoshandisa Laser Direct Imaging (LDI) uye vacuum etching technologies. Tinoshandisawo mitemo yakasimba ye millimeter-wave processing standards kuArlon 25N sezvatinoita pakugadzira mabhodhi e radar emotokari e77GHz akaita seIsola Astra MT77 . Tinokurudzira vagadziri kuti vatsanangure 0.5 oz (18 μm) kana 1 oz (35 μm) base copper, sezvo mhangura inorema inoda makemikari akasimba anobvisa maRF traces mashoma.

Kubatsira kweThermoset: Kuburikidza nePlating uye Kugadzikana

Chinhu chikuru chinobatsira Arlon 25N PCB ndechekuti inogona kugadzirwa pasi pefekitori. Kusiyana nema PTFE laminates anonyungudika seTaconic RF-60A , Arlon 25N haidi vacuum plasma desmear yakasarudzika kana sodium wet etching ine njodzi kuti igadzirire madziro ekushandisa copper plating. Inoshandisa nzira dzakajairwa dze alkaline permanganate desmear seFR-4 yakajairika, ichideredza zvakanyanya njodzi dzekugadzira uye kudzivirira kuputika kwePTH.

Uyezve, sisitimu ye resin ine cross-linked inopa kugadzikana kwakanyanya. Patinocheka mapuraneti emhangura akakora panguva yekugadzira multilayer, Arlon 25N inodzivirira kuderera kwakanyanya kweanisotropic kunokanganisa PTFE composites dzakapfava dzakadai seTaconic TLX-8 . Izvi zvinotibvumira kuchengetedza kushivirira kwakanyanya kwekunyoresa pane RF stackups dzakaoma, dzakasimba.

Dhizaini yeHybrid Stackup Kuti Iwedzere Mutengo weArlon 25N

Nekuti ma microwave laminates asingadhuri zvakanyanya anodhura zvakanyanya kupfuura masisitimu e epoxy akajairwa, kuvaka bhodhi rese rine zvidimbu gumi neArlon 25N hakuwanzo dhura mari yakawanda kunze kwekunge dhizaini yese ichishanda munzira ye microwave.

Mhinduro yemuindasitiri iyi imhando yehybrid stackup isina kuenzana. Tinochengetera Arlon 25N chete yeRF signal layers dzakakosha tichiibatanidza nedigital layers dzakavimbika zvikuru. Nekuti Arlon 25N ithermoset resin, ine curving kinetic profile inoenderana zvikuru nehigh-speed digital laminates seIsola I-Speed ​​​​uye high-Tg FR-4. Kuenderana uku kunotibvumira kugadzirisa bhodhi zvakanaka, tichidzikisa mari yako yese ye bare board ne40-60% zvichienzaniswa ne pure monolithic RF stackups pasina kukonzera asymmetric warpage.

Nguva dzekutungamira dzemuenzaniso uye Kusimbiswa kweImpedance

Kune mainjiniya eRF, prototype inokurumidza haibatsiri kana ikatadza kushanda sezvakamboitwa. Kubudirira kweprototype yepamusoro kunoda musanganiswa wekuwanikwa kwezvinhu zviripo uye kuongororwa kwakasimba kwemagetsi epamberi. Tinoderedza kunonoka kwecheni yekugovera nekuchengetedza ukobvu hweArlon hwakajairwa, zvichitibvumira kutanga kugadzira nekukurumidza mushure mekubvumidzwa kweDFM.

Uyezve, jiometri yezita haina kukwana pamabhodhi e microwave. Tinorayira kuti Time Domain Reflectometry (TDR) iongororwe kune ese ma high-frequency builds. Tinoedza makuponi akakodzera akavakirwa papaneru yako chaiyo yekugadzira kuti tipe chiyero chaicho chemitsetse yekutumira yakagadzirwa. Kutumirwa kwega kwega kweprototype kunosanganisira package yekusimbisa yakanyorwa inosanganisira kuyerwa kweTDR impedance uye ongororo ye stackup cross-section.

Gungano reTurnkey reArlon 25N PCBs

Kana Arlon 25N PCB yakagadzirwa yabuda muchitoro, kuburitswa kwega kwega kwega kwechinhu kunounza njodzi. Nzvimbo dzeRF dzinogona kubatwa nekukwenywa, kukuvara kwemucheto, uye kupisa kusingadzoreki. Kune zvigadzirwa zveRF zvepamusoro, turnkey assembly—apo kugadzirwa, kuwanikwa kwezvikamu, kuiswa kweSMT, uye kuongororwa zvinotarisirwa pasi pedenga rimwe chete—ndiyo nzira yakachengeteka uye inoshanda zvakanyanya yekutenga.

Kugona kwedu kwakabatanidzwa kwe turnkey kwemabhodhi e RF ane frequency yakakwira kunosanganisira:

• Kuiswa kweSMT kwakaringana: Kururama chaiko kwekutenderera uye kwenzvimbo dzekubatanidza ma edge-launch, network dzakanyatso patsanurwa, uye nzira dzakafanana dzekugadzira mabheramu.
• Kugadzirisa Kupisa Kwakagadziriswa: Kuyerera kwemvura kunodzora nitrogen kuti mvura irambe ichinyorova zvakanaka pasina kudzvanya substrate zvakanyanya.
• Kuongorora kwe3D X-Ray neAOI: Kuongorora nemaziso hakugone kusimbisa majoini akavanzwa. Tinoshandisa 3D X-ray (AXI) kuona zvikanganiso zviri pakati pemapakeji asina kuvharwa, akabatana, uye akarongeka pasi pemapakeji akagumiswa pasi (QFNs, LGA modules) uye ma RF modules akadzivirirwa.

Nekuchengetedza chivakwa chose pasi pechimiro chimwe chete chemhando yepamusoro, turnkey assembly inoderedza njodzi dzekugadzirisa, inoita kuti goho rirambe riripo, uye inopa shanduko inokurumidza uye yakasimbiswa kubva pabhodhi risina chinhu kuenda kune subsystem yeRF yakagadzirira kugadzirwa.
