Mugadziri weChina Taconic CER-10 PCB | Kugadzira Nekukurumidza

Kuwana mutengesi akavimbika wemabhodhi eRF ane frequency yakakura idambudziko guru kumapoka ekutenga zvishandiso. Taconic CER-10, ine dielectric constant yayo yakanyanya ye10.0, yakakosha pakuita kuti zvikamu zve microwave zvive zvishoma senge patch antennas uye power dividers zvive zvishoma. Zvisinei, nekuda kwekugadzirwa kwayo kwePTFE yakazara neceramic, mafekitori mazhinji ePCB anoramba kuitora, haana zvinhu zviripo, kana kuti haakwanise kusangana nemhedzisiro ye impedance inodiwa pakushanda kweRF. Mainjiniya anofunga nezveRO3206 sesarudzo yakasiyana ye high-Dk laminate anofanira kuenzanisa ma datasheets chaiwo uye zvirambidzo zvekugadzira pane kufunga kuti zvinhu zvakasiyana zve high-Dk zvinogona kuchinjana.

Unoda mubatsiri wekugadzira anonzwisisa mamiriro ezvekutengeserana uye ehunyanzvi ekugadzirwa kwemagetsi eDK RF. Semugadziri weChina Taconic CER-10 PCB anotungamira , Highleap Electronics inopa mitengo yakananga kubva kufekitori, prototyping nekukurumidza, uye kugona kwakasimbiswa kwekugadzira zvinhu zvakawanda. Tine zvinhu zvakagadzirwa, michina yepamusoro, uye rutsigiro rweinjiniya rwekutumira ma microwave boards ako nenguva uye nebhajeti.

Kumbira Mutengo weTaconic CER-10 Fabrication

Kugona kweTaconic CER-10 High Dr PCBs

Pakutsvaga mugadziri webhodhi redunhu rakadhindwa reCER-10, vatariri vekutenga nevatungamiriri vemidziyo yemagetsi vanofanirwa kuziva miganhu chaiyo yekugadzirisa zvinhu mufekitori. Isu takashongedzerwa zvakakwana kuti tikwanise kugadzirisa zvinodiwa zvePTFE laminates zvakazadzwa neceramic.

Kugona kwedu kwekutanga kwekugadzira Taconic CER-10 high dk PCB kunosanganisira:

• Layer Count: Zvikamu zviviri kusvika makumi maviri zvichikwira (kusanganisira zvivakwa zvakaoma zvehybrid).
• Min Trace/Space: 3 mil / 3 mil (kuburikidza neLaser Direct Imaging kuti uwane RF geometries chaiyo).
• Kushivirira kweImpedance: ±5% kusvika ±10% (yakasimbiswa nePolar Instruments uye TDR testing).
• Zviremu zvemhangura: 0.5 oz kusvika 1 oz (inodzorwa zvakasimba kudzivirira kuchekwa kwezvisaririra).
• Surface Inopedzisa: Kunyudza Sirivha, ENEPIG, ENIG, uye OSP (yakagadzirirwa kurasikirwa zvishoma kwekuisa).

Kugadzirisa Mutengo Wako weTaconic CER-10 PCB Prototype

Ma laminate ane mafrequency akakwirira anomiririra chikamu chikuru chemutengo wako weBill of Materials (BOM). Kushandisa Taconic CER-10 pachikamu chimwe nechimwe chebhodhi rine ma layer masere kutambisa bhajeti rako zvakanyanya kana chikamu chepamusoro chete chiine chiratidzo cheRF.

Kuti tideredze zvakanyanya mutengo weTaconic CER-10 PCB prototype yako, timu yedu yeinjiniya inonyanya kugadzira dhizaini yehybrid stackup isina kuenzana. Isu tinoshandisa CER-10 inodhura chete kune zvikamu zvakakosha zvekunze, uye tinoibatanidza neTg FR-4 inodhura, ine mutengo wakaderera (yakadai seIsola 370HR) yedhijitari yako yemukati uye mapurani emagetsi. Nekuongorora sarudzo yako yepamusoro yePCB laminate , tinogona kuderedza mitengo yezvinhu zvako zvekubikisa nekusvika ku40% uku tichichengetedza kugadzikana kwakakwana kwepaneru uye mashandiro eRF.

Kukurumidza Kuchinja Kwekugadzira Mabhodhi eMicrowave eCER-10

Nguva yekutenga zvinhu zvitsva inokosha zvikuru mumakambani ekutaurirana nendege. Kumirira kwemavhiki kuti fekitari iwane zvinhu zvitsva kubva kunze kwenyika hazvigamuchirwi.

Sefekitori yeTaconic CER-10 ceramic PCB yagara iripo, tine zvinhu zvakawanda zvema laminates anozivikanwa ane ma frequency akawandisa, kusanganisira ukobvu hwakasiyana hweTaconic CER-10. Izvi zvinotibvumira kutanga kugadzira bhodhi rako rema microwave reCER-10 nekukurumidza mushure mekubvumidzwa neDFM. Kunyangwe uchida prototype yekukurumidza kusimbisa dhizaini itsva ye antenna kana mubatsiri akavimbika wekugadzira zvinhu zvakawanda, mitsetse yedu yekugadzira mabhodhi akawanda yakagadziridzwa kuti ikurumidze pasina kukanganisa mwero wemhando yeIPC Class 2 kana Class 3.

Kudzora Kusapindirana Kwakasimba paDk 10.0 Laminates

Chinangwa chose chekusarudza bhodhi reTaconic CER-10 high dielectric ndechekuita kuti circuit miniaturization ive shoma. Nekuti DDK yakakura 10.0, physical trace width inodiwa kuti usvike pachinangwa che50-ohm characteristic impedance chakamanikana zvikuru—kazhinji kacho kanenge kadiki pane hupamhi hunodiwa pastandard FR-4. Iyi miniaturization yakanyanya inounza njodzi huru mukugadzirwa kweRF: trace undercut.

Musungo weTrapezoidal Etching

Mukugadzirwa kwemabhodhi edunhu akadhindwa, mabhodhoro ekugadzira makemikari anodya mhangura yakafumurwa kuti igadzire maronda. Zvisinei, mvura yekucheka haingocheki chete; inochekiwo mumativi emadziro emutsara wemhangura. Pabhodhi redhijitari rakajairwa, kuchekidzwa kudiki kwemativi kunogamuchirwa. Asi pamutsetse we microwave weCER-10 microscopic, kuchekidzwa kwe 0.5 mil kunoshandura mutsetse weRF wakakora zvakakwana kuita trapezoid. Izvi zvinoshandura capacitive coupling yemutsara, zvichichinja impedance ne5 kusvika 10 ohms uye zvichikonzera kufa kwechiratidzo (Return Loss) mu radar yako kana antenna module.

Mhinduro yeLDI neVacuum Etching

Kuti tidzivise izvi uye kuti tive nechokwadi chekuti zvinobatana neRF simulation software yenyu, Highleap Electronics haikwanise kudzivirira kusvibiswa kwemask efirimu. Isu tinoshandisa Laser Direct Imaging (LDI) chete kune ese maRF routing layers ane frequency high-frequency. LDI inoshandisa laser ine collimated zvakanyanya kuti itsanangure trace geometry zvakananga pa photoresist nemazvo. Uyezve, mitsetse yedu ye vacuum etching inokurumidza kudhonza etching fluid kubva pamusoro pemhangura, ichidzivirira kemikari kuti isagare pamadziro etrace sidewalls. Musanganiswa uyu unotibvumira kuchengetedza madziro emhangura akamira zvakanaka, achisvika ±5% impedance tolerances pamagadzirirwo eRF akapfava.

DFM Constraint: Copper Weight vs. Trace Precision

Nekuti kushivirira kwe etching kwakakosha zvikuru pazvinhu zveDk 10.0, tinosimbisa mitemo yakasimba yeDesign for Manufacturability (DFM) maererano nehuremu hwemhangura. Tinokurudzira zvikuru mainjiniya ehardware kuti vatsanangure mhangura ye0.5 oz (18 µm) kana 1 oz (35 µm) yeRF layers dzavo. Isu tinoramba magadzirirwo anotsanangura mhangura inorema ye2 oz kana inorema paCER-10 routing layers. Etching mhangura yakakora inoda kugara ichishandiswa nemakemikari, zvichiita kuti zvisakwanise kudzivirira kukanganiswa kwakanyanya kwemativi emadziro pamitsetse yakamanikana.

Kuongororwa kweTDR uye Kuvimbiswa Kwemhando

Hatisiyi mashandiro eRF yako kuti aitike netsaona. Tisati tacheka panel imwe chete, mainjiniya edu eCAM anoshandisa macalculator ePolar Instruments impedance kuti aongorore hupamhi hwetrace yako zvichienderana nezvinhu zvedu chaizvo zvekugadzira zvemufekitori. Kana paine kugadziriswa kunodiwa kuti usvike pachinangwa chako che50-ohm, tichakupa mushumo westackup wakabhadharwa kuti ubvumidzwe. Mushure mekugadzirwa, tinoedza makuponi e physical impedance tichishandisa michina yeTime Domain Reflectometry (TDR). Batch yega yega yekugadzira inotumirwa nemushumo weTDR wakakwana, ichikupa humbowo hwakanyorwa hwekuti mabhodhi ako e-high-Dk anosangana nezvaunoda chaizvo.

Basa Rekugadzira PCB reTaconic CER-10 Rakazara

Kugadzirisa PTFE kunoda michina yakasarudzika iyo isina mabhodhi eFR-4. Kana fekitori ikaedza kubatanidza Teflon pasina kugadziriswa kwakakodzera, mhangura inobviswa, zvichiita kuti circuits dzivhurike panguva yekubatanidzwa kwekupedzisira.

Kana ukashandisa sevhisi yedu yekugadzira Taconic CER-10 PCB, unenge uchibatana nekambani inoshandisa mitsetse yekugadzira ine mafrequency akawanda. Isu tinoshandisa makamuri eplasma evacuum mumba uye maitiro ekugadzira makemikari ekugadzira PTFE yakazadzwa neceramic kuburikidza nemadziro kuti inamatire mhangura zvakanaka. Ongorora kugona kwedu kwePCB yepamusoro-soro kuti uone kuti tinovimbisa sei maburi akavimbika (PTH) pamidziyo yakaoma zvikuru.

Turnkey PCBA kubva kuTaconic CER-10 RF PCB Supplier

Kubata ma microwave boards anonzwa kumeso kune vatengesi vakasiyana-siyana injodzi huru yekufambisa. Zvishandiso zvePTFE zvinogona kukuvara pakubata, uye kukwenya kamwe chete pane trace yakakosha yeRF panguva yekutumira kunogona kukanganisa module inodhura.

Kuti tipe mhinduro chaiyo yechokwadi, Highleap Electronics inoshanda semupi weTaconic CER-10 rf PCB. Tinoshandura purojekiti yenyu kubva pamitsetse yedu yekugadzira bhodhi isina chinhu zvakananga kunzvimbo yedu yekugadzira PCBA yemuchadenga . Nekuchengeta purojekiti yenyu pasi pedenga rimwe chete, tinobvisa kutenderedza kwemutengesi. Tinoshandisa 3D X-Ray (AXI) inspection kuti tive nechokwadi chekuti thermal grounding iri pasi pematransceivers enyu eRF ane simba guru.
