Kodi High Frequency PCB ndi chiyani? Nanga bwanji kugwiritsa ntchito ma frequency PCB?Tiyeni tikambirane za izi limodzi.
High Frequency PCB ndi gulu lapadera lozungulira lomwe lili ndi ma frequency apamwamba a electromagnetic. Kuthamanga kwafupipafupi kumakhala pamwamba pa 1 GHz. High Frequency PCB ili ndi zofunika kwambiri pazinthu zakuthupi, zolondola komanso zaukadaulo. Amagwiritsidwa ntchito kwambiri mu Radar, Zida Zankhondo, Azamlengalenga ndi zina.

Choyamba, High-Frequency PCB zipangizo? Kuchita kwa High-Frequency PCB mu mawaya kapena nthawi zina zothamanga kwambiri zimatengera zida zomangira. Pazinthu zambiri, kugwiritsa ntchito zinthu za FR4 kumatha kusintha mawonekedwe a dielectric. Mukapanga PCB yothamanga kwambiri, zida zomwe zimagwiritsidwa ntchito kwambiri ndi Rogers, Isola, Taconic, Panasonic, Taiyao ndi ma board ena.

DK ya High-Frequency PCB iyenera kukhala yaying’ono komanso yokhazikika. Nthawi zambiri, zazing’ono zimakhala bwino. High-Frequency PCB ipangitsa kuchedwa kufalitsa ma siginecha. DF iyenera kukhala yaying’ono kwambiri, yomwe imakhudza kwambiri khalidwe la kufalitsa chizindikiro. DF yaying’ono imathanso kuchepetsa kutayika kwa ma sign. M’malo achinyezi, imakhala ndi mayamwidwe ocheperako komanso mphamvu yoyamwa madzi, zomwe zimakhudza DK ndi DF.

Kutentha kowonjezera kutentha kwa High-Frequency PCB kuyenera kukhala kofanana ndi zojambula zamkuwa momwe zingathere, chifukwa High-Frequency PCB ingayambitse kupatukana kwa zojambulazo zamkuwa pakakhala kuzizira ndi kutentha, ndipo zikhale zofanana ndi zojambula zamkuwa momwe zingathere, kuti zitsimikizire kuti PCB ya High-Frequency ikugwira ntchito bwino. High Frequency PCB ili ndi mawonekedwe a kukana kutentha, kukana kwa dzimbiri kwa mankhwala, kukana kwamphamvu komanso kukana bwino kwa peeling.
High Frequency PCB nthawi zambiri imagwiritsidwa ntchito mu radar system, satellite, antenna, cellular telecommunication system – amplifier yamagetsi ndi mlongoti, satellite yamoyo, E-band point-to-point microwave link, tag radio frequency identification (RFID), airborne and ground radar. system, millimeter wave application, missile guide system, space satellite transceiver ndi madera ena.

Ndi chitukuko chofulumira cha sayansi ndi zamakono, ntchito za zipangizo zikukhala zovuta kwambiri. Zida zambiri zimapangidwa mu band ya ma frequency a microwave kapena kupitilira ma millimeter wave. Izi zikutanthawuzanso kuti mafupipafupi akuchulukirachulukira, ndipo zofunikira za gawo lapansi la board board zikuchulukirachulukira. Ndi kuchuluka kwa ma frequency a siginecha yamagetsi, kutayika kwa zinthu za matrix kumakhala kochepa kwambiri, chifukwa chake kufunikira kwa board-frequency board kumawonetsedwa.
