Dhizaini yeRF PCB kubva padzidziso kuenda pakuita: Gwaro Reinjiniya Rakakwana rakanyorwa naRich Full Joy

Muindasitiri yemagetsi iri kushanduka nekukurumidza nhasi, Dhizaini yePCB yeRF (Radio Frequency)inoita basa rakakosha mukugonesa mashandisirwo ekumhanya kwakanyanya uye anowanzoitwa kakawanda senge Kutaurirana kwe5G, IoT, ndegeuye radar yemotokariSekambani ine makore akawanda eruzivo rwakadzama muinjiniya yePCB ine mashandiro akawandisa, Mufaro Wakazara Wakapfumainodada kugovera ruzivo rwehunyanzvi kune vagadziri vePCB vari kutsvaga kugona matambudziko ekugadzira bhodhi reRF.

Masaini eRF anowanzo shanda mu 300MHz kusvika 300GHz, uye kugadzira PCB yemafrequencies akadaro kunounza matambudziko akasiyana asingaonekwe mumasisitimu ane kumhanya kwakaderera. Izvi zvinosanganisira kuvimbika kwechiratidzo, Kudzvinyirira kweEMI, mashandiro e dielectric zvinhuuye kufananidza kwakarurama kwe impedanceMugwaro iri rakazara, tinoongorora nzira dzakanakisisa dzekugadzira maRF PCB akavimbika uye anoshanda.

Kunzwisisa maRF PCB

An RF PCBibhodhi redunhu rakadhindwa rinoshanda pamafrequencies eredhiyo, rinowanzo batanidza ese ari maviri dijitariuye zvikamu zveanalogi, vachigadzira chinozivikanwa se bhodhi rezviratidzo zvakasanganiswaDambudziko riripo pano riri mukutarisira kudyidzana pakati pemhando dzezviratidzo, sezvo kurongeka kusina kunaka kunogona kukonzera kukanganiswa kukuru uye matambudziko ekufungisisa.

Zvichienderana ne kubata simba, RF PCBs dzinogona kupatsanurwa kuita:

• MaPCB eRF ane simba shoma, iyo inonyanya kukosha ruzha rwakaderera uye kunzwisiswa kwezviratidzo
• MaPCB eRF ane simba guru, izvo zvinoda dhizaini yakasimba yekupisa uye kugadzikana kwesimba

Chikamu chimwe nechimwe chinoda kutariswa kwakasiyana panguva yekugadzira.

Nhungamiro Dzinokosha dzeRF PCB Design

1, Kusarudzwa Kwezvinhu: Nheyo yeRF Performance

Kusarudzwa kwezvinhu zve substrate kunokanganisa zvakananga kuvimbika kwechiratidzo, kugadzikana kwekupisauye kusagadzikana kwe impedancepahuwandu hwakakura hwema frequency. Zvikamu zvakakosha zvinosanganisira:

Kuwanda kweThermal (CTE)

CTE inofanira kunge ichishanda pamwe chete nezvikamu zvakasungirirwa. Kusawedzera zvakanaka kunogona kukonzera kutsemuka kwemajoini e solder kana kuti kupatsanurwa kwe trace delamination—kunyanya mu maPCB eRF ane layer yakawandaIzvi zvakakosha kune zvikamu zvinovimbika zvakanyanya zvakaita se ndegeuye nharembozha.

Dielectric Constant (Dk)

Dr anotsanangura kuti masaini anopararira nekukurumidza sei. Masisitimu eRF anowanzo da zvinhu zveDk zvakaderera uye zvakagadzikanakuti idzore impedance chaiyo uye kuti iratidze zvishoma. 5G uye millimeter-wavemashandisirwo, zvinhu zveDk zvakaderera zvakaita se RO4350Bkana RT/duroidzvinofarirwa.

Chinhu Chinoparadza (Df)

Df inoratidza kurasikirwa kwe dielectric. Mukutumira kwe high-frequency, a yakaderera DfZvakakosha kuderedza kudzikira kwechiratidzo uye kuchengetedza kuchena kwechimiro chemafungu padaro.

Zano reNyanzvi:Zvinhu zvakaita se RO4000, RO3000uye Ma laminates akavakirwa paPTFEndiwo mabhenefiti eindasitiri eRF PCBs. Mafoil emhangura akapfava asina kuomarara anobatsirawo kuderedza kurasikirwa kwechiratidzo kubva pakukanganiswa kweganda.

2, Dhizaini Yakagadzirwa Nezvikamu Zvakagadzirwa

Kugadzika kwezvikamu zveLayer kunokanganisa kudzvinyirirwa kweEMI, kugadzikana kweimpedance, uye kushanda zvakanaka kwesignali.

Kuparadzanisa Zvinhu

Zvikamu zveRF zvinofanirwa kupatsanurwa zvichienderana nebasa razvo uye simba razvo. Chengetedza nzvimbo yakakwana pakati midziyo ine simba guruuye maseketi eanalog anonzwakuderedza kupindirana kwemuviri uye kuvandudza kupararira kwekupisa.

Makwara Akasiyana

Dzivisa makwara anoyangarara kana kuti akaparadzana, ayo anoita se antenna dzisingadzorekiKana zvisingadzivisike, zvidzivirire nekudzivirira pasi kana kudzora kureba.

Kuiswa kweChikamu Chemazano

Isa zvikamu zvinoenderana ne kuyerera kwechiratidzouye mapoka anoshanda. Ma "connect" mapfupi anoderedza kupinza kwe "parasitic inductance" uye kurasikirwa nechiratidzo. Bvumira nzvimbo yakakwana ye "test probes" uye gadzirisazve mukana wekuwana.

Kuverengwa kweMarakisi & Kurongeka

Shandisa chikamu chepamusoro cheRF routing, mapuraneti epasi ari pakati, uye chikamu chepasi chematanho edhijitari kana ekumhanya kwakaderera. nzira dzekudzoka dzakasimbakuderedza kupinza kwe loop uye EMI.

Kubatanidza Simba

IC yega yega inoda kupatsanurana kwenzvimbokusefa ruzha rwemagetsi. Isa ma capacitor ekuparadzanisa padyo nemapini emagetsi, uchishandisa kukosha kwakakodzera kwehuwandu hweIC uye hunhu hweimpedance.

3. Kurongeka kweChiratidzo cheRF Chakarurama

Kufambisa RF inzira yesainzi. Chinangwa ndechekuchengetedza kudzorwa kwekudzivirirauye kuora kwechiratidzo kushoma.

Chengeta Zviratidzo Zvipfupi

Mavara mapfupi anoenzanisa kuderera kwekudzikira uye kufungisisa. Dzivisa zvipingamupinyi zvisina kufanira munzira yekufambisa.

Dzivisa Kufamba Pamwe Chete

Dzivisa kutsvedza kweRF kwakafanana uye kutsvedza kusiri kweRF. Minda yakabatana inotungamira kune kutaura kwepakatiKana zvisingadzivisike, wedzera nzvimbo uye isa chidziviriro chepasi.

Tsanangura Mapoinzi Ekuyedza

Mapoinzi ekuyedza anofanira kunge ari yakaparadzaniswa nemitsetse yezviratidzokudzivirira kukanganisa kwechiratidzo panguva yekusimbisa.

Mabhendi Akangwara

Makona eRF anofanira kunge ari yakatenderera kana kuti yakachekwa, kwete yakapinza. Chengetedza nharaunda yakakombama yeinenge Upamhi hwe2x tracekudzivirira kuratidzwa kwechiratidzo.
