Yintoni i-PCB ye-Frequency ephezulu? Kuthekani ngokusetyenziswa kwe-PCB yamaxesha amaninzi?Makhe sixoxe ngale nto kunye.
I-High Frequency PCB yibhodi yesekethe ekhethekileyo ene-electromagnetic frequency. Ubuninzi befrikhwensi ephezulu bungaphezulu kwe-1GHz. High Frequency PCB ineemfuno eziphezulu kakhulu kwiipropati zomzimba, ukuchaneka kunye nemilinganiselo yobugcisa. Isetyenziswa ngokuqhelekileyo kwiRadar, Izixhobo zoMkhosi, i-Aerospace kunye nezinye iindawo.

Okokuqala, High-Frequency PCB imathiriyeli? Ukusebenza kwe-PCB ye-High-Frequency kwi-wireless okanye ezinye iziganeko eziphezulu-frequency kuxhomekeke kwizinto zokwakha. Kwizicelo ezininzi, ukusetyenziswa kwezinto ze-FR4 kunokuphucula iimpawu ze-dielectric. Xa kusenziwa i-PCB ene-frequency high-frequency, izinto ezisetyenziswa ngokuqhelekileyo zibandakanya iRogers, i-Isola, iTaconic, iPanasonic, iTaiyao kunye nezinye iibhodi.

I-DK ye-High-Frequency PCB kufuneka ibencinci kwaye izinzile. Ngokubanzi, incinci ingcono. I-PCB ye-High-Frequency iya kubangela ukulibaziseka kokuhanjiswa komqondiso. I-DF kufuneka ibe yincinci kakhulu, echaphazela kakhulu umgangatho wokuhambisa umqondiso. I-DF encinci inokunciphisa ngokuhambelana nokulahleka komqondiso. Kwimekobume efumileyo, inokufunxeka kwamanzi aphantsi kunye nomthamo oqinileyo wokufunxa amanzi, onempembelelo kwi-DK kunye ne-DF.

I-coefficient yokwandiswa kwe-thermal ye-High-Frequency PCB kufuneka ifane naleyo yefoyile yobhedu kangangoko kunokwenzeka, kuba i-PCB ye-High-Frequency PCB inokubangela ukwahlulwa kwefoyile yobhedu kwimeko yokubanda kunye nobushushu obutshintshayo, kwaye ibe yinto efanayo naleyo yefoyile yobhedu kangangoko, ukuze kuqinisekiswe ukusebenza ngokugqibeleleyo kwe-High-Frequency PCB. High Frequency PCB ineempawu zokunganyangeki ubushushu, ukuxhathisa kwikhemikhali, ukuxhathisa impembelelo kunye nokuxhathisa okulungileyo kokuxobuka.
I-PCB ye-Frequency ephezulu isetyenziswa ngokubanzi kwinkqubo ye-radar, isathelayithi, i-eriyali, inkqubo yonxibelelwano lweselula-i-amplifier yamandla kunye ne-eriyali, isathelayithi ephilayo, i-E-band point-to-point link microwave, i-tag yerediyo frequency identification (RFID), i-airborne kunye ne-radar yomhlaba. inkqubo, imilimitha yokusetyenziswa kwamaza, inkqubo yesikhokelo somjukujelwa, i-space satellite transceiver kunye namanye amabala.

Ngophuhliso olukhawulezayo lwesayensi kunye nobuchwepheshe, imisebenzi yezixhobo iya isiba nzima ngakumbi. Izixhobo ezininzi ziyilwe kwibhendi yefrikhwensi ye-microwave okanye nangaphezulu kwe-millimeter wave. Oku kuthetha ukuba ukuphindaphinda kuyanda, kwaye iimfuno zebhodi yesekethe substrate ziba phezulu kwaye phezulu. Ngokunyuka kwefrikhwensi yomqondiso wamandla, ilahleko yemathiriyeli ye-matrix incinci kakhulu, ngoko ke ukubaluleka kwebhodi yefrikhwensi ephezulu kuphawuliwe.
