Porogaramu ya Rigid-flex PCBs: Haba hari ibitekerezo byihariye bya RF?

Muri iyi nyandiko ya blog, tuzareba ibi bitekerezo kandi dutange ubushishozi mugushushanya PCBs igoye ya porogaramu ya RF.

Rigid-flex yanditseho imbaho ​​zumuzunguruko (PCBs) ziragenda zikundwa cyane mubikorwa bitandukanye, harimo itumanaho ridafite umugozi. Izi PCB zidasanzwe zihuza guhinduka no gukomera, bigatuma biba byiza kubikoresho bisaba gutekinika gukenewe ndetse no gukenera kugororwa cyangwa gushingwa muburyo butandukanye.

Ariko, iyo bigeze kuri porogaramu ya radio (radiyo yumurongo), ibitekerezo byihariye bigomba gutekerezwa kugirango harebwe imikorere myiza.

1. Guhitamo ibikoresho: Guhitamo ibikoresho bikoreshwa muburyo bukomeye PCB ifite uruhare runini mubikorwa byayo bya RF.Kubisabwa na RF, ni ngombwa guhitamo ibikoresho bifite dielectric ihoraho hamwe nigihombo gifatika. Ibiranga bifasha kugabanya gutakaza ibimenyetso no kugoreka, bityo kuzamura imikorere rusange ya RF. Byongeye kandi, guhitamo ibikoresho byububiko hamwe nubunini nibyingenzi mukugumya kugenzura inzitizi no kwerekana ibimenyetso.

2. Gukurikirana inzira no kugenzura inzitizi: Gukurikirana neza inzira no kugenzura inzitizi ningirakamaro kubikorwa bya RF.Ibimenyetso bya RF byumva cyane kudahuza no gutekereza, bishobora kuganisha ku gutakaza no gutakaza. Kugirango ukore neza, birasabwa gukoresha tekinoroji igenzurwa no kugenzura ubugari hamwe nintera. Ibi bifasha gukomeza inzitizi zihoraho munzira yikimenyetso, kugabanya gutakaza ibimenyetso no gutekereza.

3. Kwikubita hasi no gukingira: Gutsindira no gukingira ni ingenzi ku gishushanyo cya RF kugirango ugabanye amashanyarazi (EMI) nibibazo byambukiranya imipaka.Uburyo bukwiye bwo guhaguruka, nko gukoresha indege yabugenewe yabugenewe, bifasha kugabanya urusaku no gutanga ikibanza gihamye cyerekana ibimenyetso bya RF. Byongeye kandi, gushiramo tekinike yo gukingira nko gufunga umuringa no gukingira amabati birashobora kurushaho guteza imbere akato k’ibimenyetso bya RF biva hanze.

4. Gushyira ibice: Gushyira mubikorwa ingamba ningirakamaro kubisabwa na RF kugirango ugabanye ibimenyetso byerekana ibimenyetso byatewe n'ubushobozi buke hamwe na inductance.Gushyira ibice byinshi byinshyi hafi yundi kandi kure yinkomoko y urusaku bifasha kugabanya ingaruka zubushobozi bwa parasitike na inductance. Byongeye kandi, kugumana ibimenyetso bya RF mugihe gito gishoboka no kugabanya ikoreshwa rya vias birashobora kugabanya gutakaza ibimenyetso no kwemeza imikorere ya RF.

5. Ibitekerezo byubushyuhe: Porogaramu ya RF itanga ubushyuhe bitewe no gutunganya ibimenyetso byihuse no gukoresha ingufu.Imicungire yubushyuhe ningirakamaro mu gukomeza imikorere no kwizerwa byumuzunguruko wa RF. Abashushanya bakeneye gutekereza kuburyo bukwiye bwo gukonjesha no guhumeka kugirango bagabanye neza ubushyuhe kandi birinde ibibazo byose byubushyuhe bishobora kugira ingaruka kumikorere ya RF.

6. Kwipimisha no Kwemeza: Uburyo bukomeye bwo gupima no kwemeza ni ingenzi kubishushanyo mbonera bya RF kugirango barebe ko imikorere yabo yujuje ibisabwa.Uburyo bwikizamini nkibipimo byisesengura ryurusobe, ibizamini bya impedance, hamwe nisesengura ryubudahangarwa bwibimenyetso birashobora gufasha kumenya ibibazo byose bishobora kugaragara no kugenzura imikorere ya RF ya PCBs ikomeye.

Muri make,gushushanya PCB igoye ya porogaramu ya RF bisaba gutekereza cyane kubintu byinshi. Guhitamo ibikoresho, gukurikirana inzira, kugenzura inzitizi, guhagarara, gukingira, gushyira ibice, gutekereza kubushyuhe hamwe no kugerageza nibintu byose bigomba gukemurwa kugirango bigerweho neza na RF. Mugukurikiza ibi bitekerezo byashushanyije, injeniyeri arashobora kwemeza guhuza imikorere ya RF muri PCBs igoye cyane ya porogaramu zitandukanye, harimo ibikoresho byitumanaho bidafite umugozi.
