Ni gute wakwirinda kwivanga kwa PCB kuri frequency nyinshi?
Ibice bikoresha frequency nyinshi bigomba gushyirwa mu buryo butuma bigira imirongo migufi ishoboka. Capacitors zo gukuraho (cyangwa zinyura) zigomba gushyirwa hafi cyane ya buri pin y'amashanyarazi y'ibice bikora, bityo bigabanye imiterere y'amashanyarazi mu gihe cyo guhindura ibimenyetso, kandi birinda gusubira hasi.
PCB ifite Frequency nyinshi ni iki?
PCB ifite umurongo ukoresha frequency nyinshi ni ubwoko bwa PCB yagenewe gukorana n'ibimenyetso bifite umurongo ukoresha frequency nyinshi kuva kuri 1 GHz no hejuru. Ikozwe mu bikoresho bifite umurongo ukoresha frequency nyinshi, kandi ikoreshwa mu bikoresho byinshi bisaba kohereza ibimenyetso byihuse, byizewe, bikora neza kandi bidakoresha amashanyarazi menshi hamwe n'amashanyarazi ahoraho. Muri rusange, PCB zifite umurongo ukoresha frequency nyinshi zigaragaza iterambere mu ikoranabuhanga rigezweho ry'itumanaho nka 5G, itumanaho ridafite umugozi (WIFI), sisitemu za radar, umurongo wa radiyo ya microwave, sisitemu za satelite, n'ibindi bikoresho by'ikoranabuhanga bigezweho mu buvuzi no mu gisirikare.
PCB ifite frequency nyinshi ni iki, ibyiza byayo n'ikoreshwa ryayo ni ibihe?
PCB za HF zigenwa n'uburyo bworoshye bwo gukoresha dielectric (Dk), uburyo bworoshye bwo gukoresha dissipation (Df), n'urwego ruto rwo kwaguka k'ubushyuhe. Zikoreshwa buri gihe mu ikoranabuhanga rya HDI. Zikoreshwa cyane mu itumanaho ryihuse, itumanaho, n'ikoranabuhanga rya microwave rya RF.
Ni gute wakwirinda ko ikimenyetso cy’umuvuduko wo hejuru cyateza ibibazo muri PCB yawe?
Ubuhanga nko gutandukanya imiterere y’ubutaka, kudoda imiterere y’ubutaka, no gusimbuza inyenyeri bushobora gukoreshwa kugira ngo bugabanye imiyoboro y’ubutaka no kwemeza inzira nziza zo kugarura ibimenyetso. Mu gukora imiterere y’ubutaka ikomeye kandi idakoresha impedance nyinshi, abashushanya bashobora kugabanya urusaku neza no kunoza imikorere y’imiyoboro ifite frequency nyinshi.
Ni gute wakomeza ubuziranenge bw'ikimenyetso kuri PCB?
Itegeko ryoroshye ni ugushyira ibice bikurikirana mu mfuruka z'iburyo. Gukoresha imiterere y'ubutaka kugira ngo utandukanye ibice by'ingenzi nabyo ni byiza mu kubungabunga ubusugire bw'ibimenyetso. Urusaku rw'amashanyarazi ni ikintu cy'ingenzi kandi gisaba igishushanyo mbonera cyitondewe.
Ni izihe porogaramu zisanzwe za Rogers PCB?
Antene za microwave eouioment celllar base staton na ampifers z'amashanyarazi, inki za microwave pointio-point P2P, radar za automotwe na sensors radio freguenc: identification (RFlD) tags, LNBs kuri satelite zitangaza imbonankubone.

Nanone, tugomba guhitamo ibikoresho bikunze gukoreshwa cyane, nka Rogers RO4350B, RO4003C, Panasonic MEGRON 6, MEGTRON 7 n'ibindi.
Natangira nte imiterere ya RF PCB?
Ubwa mbere tugomba kumenya imikorere n'imikoreshereze ya porogaramu zawe. Ubwa kabiri, tugomba gushushanya igishushanyo mbonera. Icya gatatu dukora dosiye za Gerber zo gukora PCB n'urutonde rwa BOM rwo guteranya PCB. Amaherezo, isesengura ryimbitse ry'ibikoresho bya RF PCB ni ngombwa, kandi bizadufasha kubona ibikoresho byacu bifite ireme kandi bifite ibiciro bishimishije.
Ni uruhe rugero rw'inshuro PCB ikoresha?
Intera y'impinduka za PCB ishobora kuva kuri 0HZ ikarenga 300GHZ. Ubusanzwe tuyita PCB ifite frequency nyinshi iyo intera y'impinduka za PCB irenze 30MHZ, kandi intera y'impinduka zirenze 3GHZ ikaba ari frequency yo hejuru cyane.
Ese ibikoresho ni byo by'ingenzi cyane kuri RF PCB?
Yego, ni byo. Ibikoresho bya RF twahisemo bizagira ingaruka zikomeye ku mikorere ya RF PCB yacu mu bikorwa byacu. Kandi, itandukaniro ry'ibiciro ni rinini ku bwoko butandukanye bw'ibikoresho bya RF. Kubwibyo, tugomba gukoresha ibikoresho bihendutse cyane kugira ngo duhuze n'ibyo dukeneye mu buryo bwa electromagnetic frequency.
Ni irihe tandukaniro riri hagati ya RF PCB na PCB isanzwe?
PCB ya RF igomba kuba ikozwe mu bikoresho bifite umurongo wo hejuru kugira ngo yuzuze ibisabwa mu kohereza ibimenyetso. Ariko PCB isanzwe ikorwa mu bikoresho bisanzwe bya FR4 kugira ngo yuzuze imikorere y'ikoranabuhanga nyuma yo guteranya PCB.
Ni irihe tandukaniro riri hagati ya RF na mikoroonde?
RF ni ngufi ya radiyo. RF na mikoroonde byombi ni ngufi cyane ya electromagnetic wave ndetse na frequency yo hejuru. Itandukaniro rikomeye hagati ya RF na mikoroonde ni interuro ya frequency. RF iri hagati ya 30MHZ na 300GHZ, naho mikoroonde iri hagati ya 1GHZ na 100GHZ.
