Kugadzira PCB yeRT duroid 5870

Kugadzirwa kwePCB yeRT duroid 5870 kunoda nzira yekugadzira inozivikanwa nePTFE nekuti mhedzisiro yeRF yapera inoenderana nekubata zvinhu, kugadzirira maburi uye copper interfaces pamwe ne laminate pachayo. Kudzora kwakakosha ndiko kudzokorora kwekuvakwa kwapera. RT/duroid 5870 inosarudzwa kana nzira yeRF ichida kurasikirwa kwakaderera, kusagadzikana kwakaderera kwe dielectric uye kugadzikana kwe broad-frequency, asi nzira yekugadzira haina kuregerera zvakanyanya kupfuura standard thermoset laminate. Chimiro chimwe chete chePTFE-rich chinotsigira ma wideband antennas uye mitsetse mirefu ye microwave chinodawo kubatwa nekungwarira, kushanda kwemaburi, kunamatira kwemhangura uye rutsigiro rwemakanika. Kuti uenzanise neRT /duroid 5880 circuit fabrication , ongorora kuvaka kwe dielectric kwakaburitswa uye RF model yezvinhu zvese.

Highleap Electronics inogadzira maPCB eRT/duroid 5870 prototypes uye maPCB ekugadzira, anosanganisira maburi akaiswa plated, edge launches, simbi-backed constructions uye RF assembly. Highleap Electronics inotarisa panhau dzekugadzira dzinoona kana mabhenefiti emagetsi achiramba aripo pakugadzirwa.

Kugadzirwa kweRT/duroid 5870 kwakanangana nekuvakwa kwebhodhi rePTFE risina kurasikirwa zvakanyanya. Kuboorwa, kugadzirira maburi, simbi, kudzora mativi uye geometry yekupedzisira yeRF zvinofanirwa kuongororwa seimwe nzira nekuti kuvaka kwakavakirwa paPTFE hakutevedzere fungidziro dzakafanana dzekugadzira seyakajairwa FR-4.

Nei Mainjiniya Vachisarudza RT/duroid 5870 yeBroadband RF PCB

Dhiki repasi rinotsigira mitsetse yakakura yekutumira uye minda isina kuzara zvakanyanya kupfuura zvinhu zvakawanda zveDki repasi. Izvi zvinogona kubatsira kune maantenna ebroadband, network dzekudya kwenguva refu, stripline, network dzinonzwa zvikamu uye hardware yeRF yemuchadenga. Haisi sarudzo yakanakisa yega yedunhu pfupi kana remakanika; thermoset laminate inogona kupa kurasikirwa kwakakwana nekugadzirwa uye kuungana kuri nyore. Paunenge uchifunga nezveimwe nzira yePTFE yeDki repasi, sarudzo ye5880 laminate nekuvaka inofanira kupedzwa usati washandisazve 5870 artwork.

Mhangura inova chikamu chesarudzo yezvinhu

Kana kurasikirwa kwe dielectric kwaderera, kurasikirwa kwe conductor kunogona kuva kwakanyanya. Foil yemhangura yakasarudzwa, final plating uye surface finish zvinofanira kuenderana ne simulation uye purchasing specification. Foil yakatsetseka inogona kuwedzera kurasikirwa, asi kuwanikwa, kunamira uye maitiro e etch zvinokoshawo. Bhodhi harifanirwe kutaurwa kubva ku "5870" chete kana kuvakwa kwemhangura kwakakosha pamagetsi.

Kukura kwezvinhu: Highleap Electronics ndiyo inogadzira uye inounganidza PCB yekuvaka kwakatsanangurwa pano. Rogers nemazita egiredhi anotsanangurwa anoratidza zvinhu zvakatarwa uye haasi tsananguro yekugadzira zvinhu zveHighleap.

Matambudziko Ekugadzira PTFE PCB

Zvivakwa zvePTFE zvakapfava zvinoda rutsigiro rwakarongwa panguva yemifananidzo, kuboora, kufambisa zvinhu uye kuunganidza. Kurema kweclamp, torque yescrew uye kumanikidzwa kweconnector zvinogona kukonzera kukwira kana dhizaini yemakanika ikanyanya kushushikana. Kubata maturusi nepaneru kunofanira kuderedza kukanganiswa, uye bhodhi rapera rinofanira kuongororwa zvichienderana nedatamu dzinokosha kune housing uye launch.

Kuboorera uye kushanda kwePTFE

Makomba akavimbika akafukidzwa anoenderana nenzira yekugadzirira inoenderana nePTFE. Hunhu hwekuboorera, kubviswa kwesmear kana kuvhurwa, kuiswa kwemhangura uye kuputirwa kwekupedzisira kunofanirwa kudzorwa senzira imwe chete. Nzira chaiyo inogona kutsamira pakuvakwa uye geometry yegomba. Gomba rakapedzwa rinofanira kuongororwa nekuyedzwa kwemagetsi uye, kana zvichidikanwa, microsection pane kutorwa kubva kuchiratidzo chezvinhu.

Mipendero, kuburitswa uye simbi inotsigirwa

Zvinobatanidza mativi uye mipendero yakaputirwa zvinoda nzira yakagadzikana uye kuputirwa nekuti kuburitswa kunogona kugara pedyo nemuganhu. Kutsigira simbi kunowedzera kuomarara uye kupararira kwekupisa asi zvakare kunounza zvinodiwa zvekubatanidza uye kupfava. Chikamu chekubatanidza uye kumanikidzwa kwekubatanidza hazvifanirwe kukanganisa nzvimbo yeRF dielectric.

Peji reHighleap rekugadzira maPCB akagadzirwa kakawanda rinopa ruzivo rwakawanda pamusoro pePTFE ne RF dzakasanganiswa.

Kufunga Nezvekuungana uye Zvekuchengetedzwa Kwezvakatipoteredza kwe5870

5870 inogona kusarudzwa kuti ishandiswe muzvinhu zvekufambisa mhepo, zvinodzivirira kutonhora, zvinonzwa hunyoro kana kuti zvinoshandisa broadband, asi chinhu chose chinoramba chichisarudza maitiro emumunda. Connector torque, housing support, namatidza, soldering uye thermal cycling zvinofanirwa kuongororwa pamwe chete. Bhodhi rakatetepa risingatsigirwi nekanika rinogona kuchinja chimiro panguva yekubatanidza kunyangwe kana zvinhu zvaro zvemagetsi zvakakodzera.

Pazvinhu zvakaunganidzwa, Highleap inogona kuronga kuwanikwa kwezvikamu, SMT kana kubatanidza zvinhu kuburikidza neburi, kuiswa kweconnector uye kuyedzwa kwakabvumiranwa. Zvigadziko zvinofanirwa kutsigira bhodhi pasina kuchinja mamiriro aro emakanika. Kurongedza nekutumira zvinhu zvinofanirawo kudzivirira kukotama kana kukwira panzvimbo.

Kugona Kugadzira RT/duroid 5870 Isati Yagadzirwa

Ongororo yekugona kwayo inoenzanisa kurasikirwa kunodiwa uye bandwidth nemari yekugadzirisa PTFE, kuvaka mhangura, rutsigiro rwemakanika uye qualification. Mune mamwe mapurojekiti, 5880, RO3003 kana thermoset material zvingave zviri nani. Mune mamwe, 5870 ine chikonzero nekuti RF margin haigone kushivirira kurasikirwa kwakanyanya kana kuwanda kwesimba remunda.

Uchapupu hwekuvaka kunodzokororwa

Pakeji yekuburitsa inofanira kusanganisira zvinhu nemhangura, ukobvu hwakapedzwa, RF geometry, maburi, zvinodiwa pamucheto, ruzivo rwekubatanidza kana kuseri, kupedzisa kwenzvimbo, datums dzemakanika uye nzira yekuyedza. Highleap inogona kupa prototype uye kugadzirwa kwehuwandu hushoma dhizaini isati yachinjirwa kukugadzirwa kwakadzokororwa. Highleap inoongorora kuchera, desmear kana kugadzirira kwenzvimbo, kunamatira kwemhangura, lamination uye RF geometry secheni imwe chete yekushanda. Chinyorwa chekutanga chinogona kushandiswa kusimbisa kuvakwa kwegomba uye zvivakwa zve impedance usati waburitsa kugadzirwa kwakadzokororwa. Kukosha kwepfuma chaiyo yezvinhu kunofanirwa kuongororwa zvichienderana nemagwaro emutengesi aripo egiredhi rakatarwa uye kuvaka.

Mibvunzo ye5870 yekugadzira

Ko 5870 inogona kubatwa seFR-4 here? Kwete. Kugadzirira kwakanangana nePTFE uye rutsigiro rwemakanika zvinodiwa.

Ko mhangura yakatsetseka inonyanya kudiwa here? Kwete nguva dzose. Zvinoenderana nebhajeti yekurasikirwa, geometry, kuwanikwa uye zvinodiwa zvekunamatira. Kuti uwane mutengo, ipa giredhi, ukobvu, mhangura, tekinoroji yegomba, kupedzisa, bhendi rekushanda uye huwandu. Taura chero chinodiwa chekuyera RF kuitira kuti mutengo uvhare kusimbiswa kunodiwa pane kufunga kuti kuongororwa kweFR4 kwakakwana.
