Chii chinonzi High Speed PCB?

"High Speed" inowanzo dudzirwa kureva maseketi uko kureba kwechiratidzo kusimuka kana kudonha kwemupendero kwakakura kupfuura chikamu chimwe muzvitanhatu cheurefu hwetambo yekufambisa yakakura kupfuura kureba kwetambo yekutapurirana, ipapo kureba kwemutsara kunoratidza maitiro emutsetse.

Mune high speed PCB , nguva yekusimuka inokurumidza zvakakwana zvokuti bandwidth yechiratidzo chedhijitari inogona kuwedzera kusvika kune yakakwirira MHz kana GHz frequencies. Kana izvi zvikaitika, pane mamwe matambudziko ekusaina ayo anozoonekwa kana bhodhi isina kugadzirwa uchishandisa yakamhanya PCB dhizaini mitemo. Kunyanya, munhu anogona kuona:

1. Kurira kwakakura kusingagamuchirwi. Izvi zvinowanzoitika kana zvisaririra zvisina kupamhama zvakakwana, kunyangwe iwe uchifanira kungwarira paunenge uchiita kuti zviteshi zvako zviwedzere (ona chikamu cheImpedance Contorl muPCB Dhizaini pazasi). Kana kurira kwechinguvana kwakakura zvakanyanya, iwe uchave nehombe yakawandisa kana undershoot mune yako chiratidzo chekuchinja.

2.Strong crosstalk. Sezvo kumhanya kwechiratidzo kuchiwedzera (kureva, nguva yekusimuka painodzikira), capacitive crosstalk inogona kuve yakakura seyazvino inokonzeresa zviitiko capacitive impedance.

3.Reflections kubva kune mutyairi uye anogamuchira zvikamu. Masiginecha ako anogona kuratidza kubva kune zvimwe zvikamu pese painenge paine impedance mismatch. Ingave kana kwete iyo impedance mismatch inova yakakosha inoda kutarisa iyo impedance yekupinza, mutoro wekudzivirira, uye mutsara wekutapurirana hunhu impedance yekubatanidza. Unogona kuverenga zvakawanda pamusoro peizvi muchikamu chinotevera.

4.Matambudziko ekuvimbika kwesimba (nguva pfupi yePDN ripple, pasi bounce, nezvimwewo). Iyi ndiyo imwe seti yezvinetso zvisingadzivisiki mune chero dhizaini. Nekudaro, yenguva pfupi PDN ripple uye chero mhedzisiro inokonzeresa EMI inogona kudzikiswa zvakanyanya kuburikidza neyakakodzera stackup dhizaini uye decoupling matanho. Iwe unogona kuverenga zvakawanda nezve yakakwira PCB stackup dhizaini gare gare mune ino gwaro.

5.Yakasimba yakaitwa uye yakavhenekera EMI. Chidzidzo chekugadzirisa matambudziko eEMI chakakura, padanho reIC uye padanho repamusoro PCB dhizaini. EMI inongova nzira yekudzorera; kana iwe ukagadzira bhodhi rako kuti rive rakasimba EMI kusadzivirirwa, ipapo rinozoburitsa shoma EMI. Zvekare, zvizhinji zveizvi zvinowira pasi pakugadzira iyo chaiyo PCB stackup.

High-frequency PCBs inowanzopa frequency range kubva pa500MHz kusvika 2 GHz, iyo inogona kusangana nezvinodiwa zvehigh-speed PCB magadzirirwo, microwave, radiofrequency, uye nharembozha. Kana iyo frequency iri pamusoro pe1 GHz, tinogona kuitsanangura seyakakwira frequency.

Kuoma kwezvinhu zvemagetsi uye ma switch ari kuramba achiwedzera mazuva ano uye anoda kukurumidza kuyerera kwechiratidzo. Saka, ma frequency ekufambisa epamusoro anodiwa. MaPCB epamusoro-frequency anobatsira zvakanyanya pakubatanidza zvinodikanwa zvechiratidzo muzvikamu zvemagetsi uye zvigadzirwa zvine mabhenefiti akafanana nehunyanzvi hwepamusoro, uye kukurumidza kukurumidza, kudzikisira, uye kugara kwedielectric properties.Dzimwe kufunga kwepamusoro-frequency PCBs kugadzira.

High-frequency PCBs inonyanya kushandiswa muredhiyo uye yakakwirira-speed digital applications, yakadai se5G wireless communications, automotive radar sensors, aerospace, satellites, etc. Asi pane zvinhu zvakawanda zvinokosha zvinofanira kufungwa nezvazvo pakugadzira maPCB akakwirira-frequency.

· Multi-layered dhizaini

Isu tinowanzo shandisa akawanda-akaiswa maPCB mune yakakwira-frequency PCB magadzirirwo. Multi-layered PCBs ane gungano density uye vhoriyamu diki, zvichiita kuti ive yakakodzera kwazvo pamapakeji ekukanganisa. Uye akawanda-akaturikidzwa mabhodhi ari nyore kupfupisa kuwirirana pakati pemagetsi zvikamu uye kuvandudza kumhanya kwechiratidzo chekufambisa.

Ground plane designing chikamu chakakosha chepamusoro-frequency applications nekuti haingo chengetedza mhando yechiratidzo asi inobatsirawo kuderedza EMI radiations.High frequency board yeawaya maapplication uye data rates mukumusoro GHz renji ine zvakakosha zvinodikanwa pazvinhu zvinoshandiswa:

1. Yakagadziridzwa mvumo.

2.Low attenuation yekushanda kwechiratidzo chekufambisa.

3.Homogeneous kuvaka nekuderera kushivirira muhuputi hwekudzivirira uye dielectric nguva dzose. Iko kudiwa kwepamusoro-frequency uye yakakwirira-kumhanya PCB zvigadzirwa zvinokwira nekukurumidza mazuva ano. pcb mugadziri , YMS iri kutarisa pakupa vatengi vane yakavimbika yepamusoro-frequency PCB prototyping ine mhando yepamusoro. Kana uine matambudziko nePCB kugadzira kana PCB kugadzira, ndapota inzwa wakasununguka kutibata nesu.
