Menene Babban Mitar PCB? Me game da aikace-aikacen PCB mai girma? Bari mu tattauna game da wannan tare.
Babban Frequency PCB shine allon kewayawa na musamman tare da mitar lantarki mai girma. Mitar babban mitar yana sama da 1GHz. PCB mai girma yana da babban buƙatu don kaddarorin jiki, daidaito da sigogin fasaha. An fi amfani da shi a cikin Radar, Kayan aikin Soja, Aerospace da sauran fannoni.

Na farko, Abubuwan PCB masu girma-girma? Ayyukan PCB mai girma a cikin mara waya ko wasu lokatai masu tsayi ya dogara da kayan gini. Don aikace-aikace da yawa, amfani da kayan FR4 na iya inganta abubuwan dielectric. Lokacin kera PCB mai girma, albarkatun da aka saba amfani da su sun haɗa da Rogers, Isola, Taconic, Panasonic, Taiyao da sauran alluna.

DK na PCB mai girma ya kamata ya zama ƙanƙanta kuma barga. Gabaɗaya, ƙarami shine mafi kyau. PCB mai girma zai haifar da jinkirin watsa sigina. DF yakamata ya zama ƙanƙanta sosai, wanda yafi rinjayar ingancin watsa siginar. Ƙananan DF na iya daidai da rage asarar sigina. A cikin yanayi mai laushi, yana da ƙananan ƙarancin ruwa da ƙarfin ƙarfin ruwa mai ƙarfi, wanda ke da tasiri akan DK da DF.

Matsakaicin faɗaɗawar thermal na High-Frequency PCB yana buƙatar zama iri ɗaya da na foil ɗin tagulla gwargwadon yuwuwar, saboda PCB mai girma na iya haifar da rabuwar foil ɗin jan ƙarfe a yanayin canjin sanyi da zafi, kuma zama daidai da na tagulla kamar yadda zai yiwu, don tabbatar da ingantaccen aikin PCB mai girma. Babban Frequency PCB yana da halayen juriya na zafi, juriyar lalata sinadarai, juriya mai tasiri da juriya mai kyau.
Babban Frequency PCB ana amfani dashi gabaɗaya a cikin tsarin radar, tauraron dan adam, eriya, tsarin sadarwar salula – amplifier wutar lantarki da eriya, tauraron dan adam watsa shirye-shiryen watsa shirye-shirye, E-band point-to-point microwave mahada, alamar mitar rediyo (RFID), alamar iska da radar ƙasa. tsarin, aikace-aikacen igiyar milimita, tsarin jagora na makami mai linzami, transceiver tauraron dan adam da sauran filayen.

Tare da saurin ci gaban kimiyya da fasaha, ayyukan kayan aiki suna karuwa sosai. An ƙera kayan aiki da yawa a cikin mitar mitar microwave ko ma fiye da igiyar milimita. Wannan kuma yana nufin cewa mitar tana ƙaruwa, kuma abubuwan da ake buƙata don substrate allon kewayawa suna ƙara girma da girma. Tare da karuwar siginar siginar wutar lantarki, asarar kayan matrix kadan ne, don haka an nuna mahimmancin allon mita mai girma.
