Kugadzirwa kweTMM10i PCB uye DFM

Kugadzirwa kweTMM10i PCB kune kusimbiswa kwakasimba kweDFM nekuti hunyanzvi hudiki uye maitiro ezvinhu zvinogona kuratidza kusasimba mukuita kweCAM kwakajairika. Ongororo inobatsira ndeye mukaha uripo pakati pekudhirowa kwakaburitswa uye hwindo rekuita rinogona kudzokororwa. Kureba kwekambani: Highleap Electronics inogadzira uye inounganidza PCB yakapedzwa. Giredhi reRogers rakataurwa papeji rino rinozivisa laminate yakatarwa; Highleap haigadziri kana kutengesa Rogers laminates. Kana mainjiniya eRF vachida kuderedza zvakanyanya tsoka ye antenna yechigamba, power amplifier, kana cavity filter, vanoda substrate ine dielectric constant (Dk) inosvika 10. Kunyange zvazvo brittle alumina ceramic yaishandiswa kare pakuita izvi, Rogers TMM10i inopa imwe nzira inoshanda zvikuru: thermoset hydrocarbon resin yakazara neceramic inopa isotropic Dk ye9.80 uku ichichengetedza flat form factor yebhodhi redunhu rakadhindwa. Kufanana kwemazita kunoita kuti zvinodiwa zvekugadzira TMM10 compact-circuit zvakakodzera kuongororwa zvakajeka usati watanga kuchinja kwekutenga.

Zvisinei, kunyange hazvo kugadzira bhodhi re microwave reTMM10i thermoset musoftware yekufananidza kuri nyore, kugadzira kwacho kwakaoma zvikuru. Nekuti zvinhu zvacho zvakakora uye zvinokwesha, dzimba dzebhodhi dzemazuva ano dzinowanzo paradza maturusi avo eCNC uye mapaneru akachekwa pakutanga. Kubudirira kugadzira PCB ye microwave yeRogers TMM10i kunoda mugadziri anonzwisisa zvakanyanya miganhu yemakanika e laminates ane ceramic yakawanda.

Kumbira Ongororo yeTMM10i DFM

Sei Uchifanira Kusarudza Rogers TMM10i yeDk 9.80 Microwave Designs?

Mazhinji ma laminates ane mafrequency akakwira, kusanganisira FR-4 yakajairwa uye akawanda maturusi ePTFE, anoshandisa fiberglass yakarukwa kuti itsigire chimiro. Izvi zvinogadzira anisotropic effect—zvichireva kuti dielectric constant inosiyana zvishoma zvichienderana nekuti chiratidzo cheRF chinofamba here pamwe chete neX, Y, kana Z axis.

TMM10i yakagadzirwa zvakasiyana isina girazi rakarukwa. Izvi zvinoita kuti chinhu chacho chive chakasiyana zvachose. Kune mainjiniya anogadzira maumbirwo akaomarara e3D waveguide, iyo Dk inoramba iri 9.80 chaiyo muzvikamu zvese zvitatu. Izvi zvinovandudza hukama pakati pemamodheru eHFSS kana CST nebhodhi remuviri, asi hukama hwekupedzisira huchiri kuda data rakaburitswa uye rekuyera. Pamusoro pezvo, iyo Coefficient of Thermal Expansion (CTE) iri pedyo zvikuru nemhangura, ichidzivirira kutadza kweplated through-hole (PTH) panguva yekupisa kwakanyanya munzvimbo dzemuchadenga.

Matambudziko Ekugadzira eTMM10i: Kuchekwa Kwezvidhinha uye Kupwanyika Kwezvinhu Zvidiki 

Kuti vawane 9.80 Dk, Rogers anozadza hydrocarbon resin zvakanyanya ne silica ne ceramic particles. Panel inobuda haishande se plastic PCB asi inoita se ceramic plate isina kusimba. Iri ndiro dambudziko guru rekugadzirwa kwe TMM10i RF board. Kana fekitori ikashandisa machining parameters akajairwa kune izvi, goho remushonga rinodzikira.

Chikonzero Chinokonzera Kukundikana: Kukanganisa Kudiki

Chinozadza ceramic chiri muTMM10i chinoshanda sesandpaper ine microscopic panosangana neCNC drill bits. Pakuboora panel yakajairwa yeFR-4, tungsten carbide drill bit inogona kugara kwemaburi zviuru zviviri isati yaoma. PaTMM10i, mucheto wechikamu ichocho chaiwo unoparadzwa mumaburi ari pasi pezana.

Kana mugadziri akaedza kupinza chinhu chisina kusimba muchinhu ichi chisina kusimba kuti achengetedze mari, hachizocheki resin zvakanaka. Asi, chinobaya nekupwanya nzira yacho. Simba iri rinoita kuti pave nekutsemuka kwakanyanya pamadziro ane maburi.

Kutsemuka uku kusingaonekwe, kudiki diki kunoshanda semasiponji, kunobata makemikari ekuputira panguva yekunyorova. Kana bhodhi rapfuura nepakati peSMT reflow oven, makemikari emvura aya anofashaira, anodzima gasi nekukurumidza, uye anoputitsa jira remhangura kubva pamadziro. Izvi zvinoguma nekukundikana kwe open-circuit nekukurumidza, kusingagadzirisike.

Iyo Highleap Injiniya Solution

Kuti zvidzivise zvikanganiso izvi, nyanzvi yeRogers TMM10i ceramic PCB fekitori inofanira kushandisa mitemo yakasimba yeCAM (Computer-Aided Manufacturing):

• Kuverengwa Kwema hits akavharirwa: Tinosimbisa hurongwa hwakasimba hwekutsiva ma drill bit, tichirasa ma bits zvishoma pane nguva yaanogara kuti tirambe tichishanda zvakanaka.
• Kumhanya Kwemaspindle Kwakadzikira: Tinoderedza zvakanyanya mwero wekudonha kweZ-axis (chip load) uye spindle RPM kudzivirira kupisa kwekukweshana kuti kusakonzere kupwanyika kwekupisa mu dielectric.
• Nzira yeKufamba Nedhaimani Yakachekwa: Zvidimbu zverouter zvine flute zvinobvarura zvidimbu zveceramic, zvichisiya mipendero yebhodhi yakakombama. Tinoshandisa zvidimbu zverouter zvine dhaimani zvakatemwa zvinomhanya zvine mwero wakagadzirwa, zvishoma nezvishoma kuti tive nechokwadi chekuti ma profiles acho akatsetseka zvakakwana.

Kunzwisisa Mari Yenyu Yekugadzira PCB yeRogers TMM10i

Mapoka ekutenga zvinhu nemainjiniya emidziyo yemagetsi vanowanzo shamisika kuti sei ma laminates ane ceramic yakawanda aine mutengo wepamusoro wekugadzira. Zvinhu zvisina kugadzirwa zvinongova chikamu che equation. Chinhu chaicho chinoita kuti mutengo wekugadzira PCB yeRogers TMM10i uve wakakura zvakanyanya (zvichitora ma drill bits akawanda ne router papaneru imwe neimwe) uye nguva yekushanda inononoka zvikuru yeCNC inodiwa kuti chigadzirwa chigadziriswe zvakanaka.

Zvisinei, TMM10i inopa mukana mukuru wekugadzirisa makemikari unoderedza zvimwe zvezvishandiso izvi. Kusiyana nezvinhu zvePTFE zvine Dk (zvakadai seRO3010), TMM10i i hydrocarbon thermoset. Haidi sodium etching ine njodzi kana vacuum plasma desmear inodhura isati yagadzirwa. Mugadziri wePCB weChina Rogers TMM10i anogona kugadzirisa mabhodhi aya kuburikidza nemitsetse yemhangura isina magetsi, zvichideredza nguva yekutungamira zvichienzaniswa nedzimwe nzira dzePTFE. Highleap inoshandisa ongororo yeDFM kuti iongorore kuboora, nzvimbo yemhangura, kunyoresa, ukobvu hwakapedzwa uye chero zvinhu zveRF zvakamanikana zvisati zvashandiswa. Zvimwe zvinoonekwa padanho reinjiniya kuitira kuti zvisave zvinoshamisa pakugadzirwa. Hunhu chaihwo hwezvinhu hunofanirwa kuongororwa zvichienderana nemagwaro emutengesi aripo iye zvino egiredhi rakatarwa uye kuvaka.

Kutsvaga Kugadzirwa Kwakavimbika uye PCBA yeMabhodhi Akazadzwa neCeramic

Muindasitiri yema microwave, kusimbiswa kwemidziyo yemagetsi kunofanira kuitika nekukurumidza. Kunyange zvazvo tichipa prototype Rogers TMM10i PCB prototyping, tinokurudzira zvakasimba kuti mabhodhi ako asina chinhu asagadzirwa panzvimbo imwe chete otumirwa kune mumwe mutengesi wechitatu kuti aunganidze. TMM10i haina kusimba zvakanyanya; kuifambisa pakati pevatengesi vakawanda kunowedzera njodzi yekupwanyika kwemucheto uye kusvibiswa kwekubata.

Kuti tibvise njodzi iyi, Highleap Electronics inoshanda semupi wePCB weRogers TMM10i ane purofiti imwe chete. Tinoshandura purojekiti yenyu nekutonga kubva kumitsetse yedu yekugadzira PCB ine frequency yakakwira kuenda kunzvimbo dzedu dzekugadzira PCB dzinotenderera.

Semugadziri wenyu weRogers TMM10i circuit board, tinoshandisa Laser Direct Imaging (LDI) kuchengetedza trace impedance yakadzikama paDk 9.80, uye tinoshandisa 3D X-Ray (AXI) inspection kuti tione kuti thermal-grounding coverage yakavharwa ne thermal-grounding plan yekuongorora pasi pe RF components dzine simba guru. Izvi zvinoita kuti chigadzirwa chenyu chekupedzisira chiite sezvakarongwa. Pa quotation, ipai kuvakwa kweTMM10i chaiko, saizi dzakakosha, impedance targets, copper, maburi nehuwandu. DFM package yakazara inobvumira quotation ne process yekugadzira kuti zvienderane.
