Chii chinonzi High Frequency PCB? Zvakadini nekushandiswa kwema frequency PCB?Ngatikurukurei nezveizvi pamwe chete.
High Frequency PCB idhisheni yakakosha bhodhi ine yakakwira electromagnetic frequency. Iyo frequency yeakakwira frequency iri pamusoro pe1GHz. Yakakwira Frequency PCB ine yakakwira zvakanyanya zvinodiwa zvemuviri zvivakwa, huchokwadi uye tekinoroji paramita. Inowanzoshandiswa muRadar, Military Equipment, Aerospace uye mamwe minda.

Kutanga, High-Frequency PCB zvinhu? Kuita kweHigh-Frequency PCB mune isina waya kana dzimwe nguva dzakakwirira-frequency zvinoenderana nezvinhu zvekuvaka. Kune akawanda maapplication, kushandiswa kweFR4 zvinhu kunogona kuvandudza dielectric zvivakwa. Kana uchigadzira yakakwira-frequency PCB, izvo zvinowanzo shandiswa mbishi zvinosanganisira Rogers, Isola, Taconic, Panasonic, Taiyao uye mamwe mabhodhi.

Iyo DK yeHigh-Frequency PCB inofanirwa kunge iri diki uye yakagadzikana. Kazhinji, zviduku zviri nani. Yakakwira-Frequency PCB ichakonzera kunonoka kutapurirana kwechiratidzo. DF inofanirwa kunge iri diki kwazvo, iyo inonyanya kukanganisa iyo chiratidzo chekufambisa mhando. Diki DF inogona kuenderana kuderedza kurasikirwa kwechiratidzo. Munzvimbo ine hunyoro, ine yakaderera kunyura kwemvura uye yakasimba yekunyudza mvura kugona, iyo ine chekuita paDK neDF.

Iyo yekupisa yekuwedzera coefficient yeHigh-Frequency PCB inoda kufanana neiyo yemhangura foil zvakanyanya sezvinobvira, nekuti iyo High-Frequency PCB inogona kukonzera kupatsanurwa kwefoiri yemhangura mune yekuchinjisa kutonhora nekupisa, uye ive yakafanana neyefoiri yemhangura zvakanyanya sezvinobvira, kuitira kuti uve nechokwadi chekushanda kwakakwana kweHigh-Frequency PCB. Yakakwira Frequency PCB ine hunhu hwekupisa kupisa, kemikari kusaita ngura, kukanganiswa kwemaitiro uye kwakanaka kupepeta kuramba.
High Frequency PCB inowanzo shandiswa mu radar system, satellite, antenna, cellular telecommunication system – simba amplifier uye antenna, live broadcast satellite, E-band point-to-point microwave link, radio frequency identification (RFID) tag, airborne uye pasi radar. system, millimeter wave application, missile kutungamira system, space satellite transceiver uye mamwe minda.

Nekukurumidza kukura kwesainzi uye tekinoroji, mabasa emidziyo ari kuramba achiwedzera kuoma. Midziyo mizhinji yakagadzirwa mumicrowave frequency band kana kutopfuura millimeter wave. Izvi zvinoreva zvakare kuti kuwanda kuri kuwedzera, uye zvinodiwa zvedunhu bhodhi substrate zviri kuramba zvichikwira nekukwira. Nekuwedzera kwesimba remagetsi frequency, kurasikirwa kwezvinhu zvematrix idiki kwazvo, saka kukosha kwepamusoro-frequency board kunosimbiswa.
