Kuungana kweRF PCB nePCB yeAdvanced Electronics
Gwaro Rakakwana reRF PCB Materials uye Applications
MaRF PCB mabhodhi edunhu akagadzirirwa kushanda zvakanaka pamafrequencies eredhiyo. Mabhodhi edunhu aya akakosha kune matekinoroji akasiyana-siyana epamusoro-soro, anosanganisira kutaurirana, masisitimu ehondo, ndege, uye midziyo yemagetsi yevatengi. Kunzwisisa kukosha kwezvinhu zvinoshandiswa mukugadzira maRF PCB kwakakosha pakuona kushanda zvakanaka uye kuvimbika.
RF PCB Materials — Nei Kusarudzwa Kwezvinhu Kwakakosha
Sarudzo yezvinhu zveRF PCBs inokanganisa zvakananga mashandiro adzo. Zvinhu zvakaita se dielectric constant, loss tangent, thermal expansion, uye hunyoro zvinofanirwa kufungwa nezvazvo kuti zvive nechokwadi chekuti masaini akasimba, kutapurirana kwepasi pasi, uye kugadzikana munzvimbo dzine mafrequency akawanda.
1. Teflon (PTFE)
Teflon (polytetrafluoroethylene) chinhu chinodiwa zvikuru paRF PCBs nekuda kwehunhu hwayo hwakanaka hwe dielectric. Ine dielectric constant yakaderera (kazhinji inenge 2.0-2.5), zvichiita kuti ive yakakodzera kushandiswa kwema frequency akawanda senge microwave circuits uye satellite communication. Teflon inodzivirira hunyoro zvakanyanya uye ine tangents shoma dzekurasikirwa, izvo zvinoderedza kurasikirwa kwesignali.
2. PTFE (Polytetrafluoroethylene)
Kufanana neTeflon, PTFE chimwe chinhu chinowanzoshandiswa mumashandisirwo emagetsi ane mafrequency akawanda. Inopa dielectric shoma uye inorasikirwa nemasaini mashoma asi inodhura zvishoma kana ichienzaniswa nezvimwe zvinhu zvepamusoro. Yakanakira masisitimu eradar, kutaurirana kwesatellite, uye zvishandiso zvisina waya.
3. Ceramic
MaPCB eCeramic anopa kufambisa kwekupisa kwakanaka uye kushanda kwemafrequency akawanda. Anoshandiswa mumashandisirwo anodiwa pakuparadza kupisa uye kunyatsoita zvinhu nemazvo, zvakaita semuchadenga, kudzivirira, uye zvemagetsi zvekurapa. MaPCB eCeramic anowanzo shandiswa muma microwave ane frequency yakawanda uko kudzora kupindirana kwemhepo uye kuderedza masaini emagetsi kwakakosha.
4. FR-4
Kunyangwe isina kugadzirwa zvakananga kumasekete ane mafrequency akawanda, FR-4 inoramba iri mhinduro inodhura zvishoma kune akawanda maRF applications. Inowanzo shandiswa mumaelectronics evatengi uye ma frequency epakati apo kurasikirwa kwemasaini hakusi kwakakosha.
5. Zvinhu zveHydrocarbon PCB
Zvinhu zvakagadzirwa nehydrocarbon zvinoshandiswa pakushandisa RF isinganyanyi kudhura. Zvinopa mwero pakati pemutengo nekushanda, zvichiita kuti zvikwanise kushandiswa pakushandisa RF circuit zvisinganyanyi kuomera.
Dhizaini yePCB Inowanzo shandiswa Kakawanda — Kusvika kumatanho makumi matanhatu nemasere eUinjiniya Hwakarurama
Kugona kwedu kugadzira maRF PCB kunosanganisira kusvika kumatanho makumi matanhatu nemasere. Izvi zvinobvumira magadzirirwo emasekete akaomarara, ane density yakakura anokwanisa kubata masaini eRF akaomarara nemazvo. MaPCB ane matanho makumi matanhatu nemasere akakodzera masisitimu epamusoro-soro e multichannel, 5G infrastructure, satellite communication, uye mamwe maapplication epamusoro-soro anoda huwandu hwakawanda hwekubatanidza uku achichengetedza saizi diki.
Kugona kubata kusvika kumatanho makumi matanhatu nemasere kunoita kuti maRF PCB edu akwanise kusangana nezvinodiwa nemacircuit ane mafrequency akanyanya kudiwa, zvichideredza kurasikirwa kwemasaini uye kuona kuti masaini akavimbika zvakanyanya.
Kugadziriswa Kwepamusoro KweRF PCBs
Kupera kweRF PCB kunoita basa guru mukushanda kwayo kwese. Kusarudza kurapwa kwakakodzera kwenzvimbo kunogona kukanganisa kutapurirana kwemasaini, kuramba ngura, uye kuvimbika kwenguva refu. Tinopa mhando dzakasiyana dzekugadzirisa pamusoro kuti zvienderane nezvinodiwa zvako:
1. Nickel-Goridhe (Ni/Au)
