Mayikirowevu kusindikizidwa dera bolodi ndipo RF PCB imafuna zochitika zapadera zomwe anzanu omwe mumapanga nawo nthawi zonse sangathe kuthana nawo. Titha kugwiritsa ntchito ma laminates othamanga pafupipafupi ndi chiwongolero cholimba ndi kuwongolera kwapamwamba kuti tipeze bwino ndikupanga RF PCB yanu kuti muwonetsetse kuti ikuyenda bwino.

Rayming wakhala akutsogolera RF mayikirowevu PCB katundu padziko lapansi, kuyang’ana pa HF PCB laminates. Rogers PCB, Teflon PCB, Arlon PCB, ndimatha kupanga zinthu zomwe mukufuna.

RF PCB

< p> Mutha kudalira ukadaulo wa Rayming chifukwa tili ndi gulu, zida ndi luso logwirira ntchito zopaka laminated zomwe zimakhala ndi zosowa zapadera zokhudzana ndi makina, matenthedwe, magetsi ndi zina zantchito zina zopitilira zida za FR-4.

Ikani zogulitsa zanu m’manja otetezeka podalira rf microwave PCB wopereka katundu yemwe amayang’ana kwambiri kulolerana ndikupereka thandizo lomwe mukufuna nthawi ndi nthawi.

Mvetsetsani zomwe hf PCBS zili,

1. Hf PCBS kapena kuyitanitsa mayikirowevu PCBS / RF PCBS / RF PCBS amagwiritsidwa ntchito kwambiri kulumikizana opanda zingwe, ma netiweki opanda zingwe komanso kulumikizana ndi satelayiti, makamaka maukonde a 3G, kukulitsa kufunikira kwa msika pazogulitsa pa HF PCBS. Masiku ano, kufunikira kwa mapangidwe a ma microwave zakuthupi za PCB kukukulira, ndipo mwayi wopeza ma data othamanga kwambiri (othamanga kwambiri) ukukhala chofunikira kwambiri pamisika ingapo monga chitetezo, malo othamangitsira malo komanso mafoni. Kusintha kofunikira pamsika kukupitilizabe kuyendetsa chitukuko cha mabatani azisindikizo apamwamba kwambiri. Monga mawayilesi a 50+ GHz microwave kapena makina oteteza mpweya, imatha kukhalanso ndi ma PCBS opanda halogen.

2. Gawo la RF Mawonekedwe apamwamba a PCBS opangidwa kuchokera ku polytetrafluoroethylene (PTFE PCB), ma cororopolymers odzaza ndi ceramic kapena zida zodzaza ndi hydrocarbon thermosetting zopangira ma dielectric. Zinthuzo zimakhala ndi ma dielectric otsika nthawi zonse a 2.0-3.8, otsika kwambiri komanso otayika kwambiri, koma amakhalanso ndi magwiridwe antchito, kutentha kwa magalasi otentha, kutsika kwambiri kwa hydrophilic, kukhazikika kwabwino kwamafuta. The koyefishienti kuwonjezeka kwa PTFE PCB zakuthupi ndi ofanana ndi zamkuwa, zomwe zimapangitsa zinthu ndi kwambiri ooneka enieni bata.

3.Panda PCB Company yawonjezeka zida zopangira ndi r & d ndalama. Kwa zaka zingapo zapitazi m’munda wa chitukuko cha HF PCB, kwa makasitomala ochokera konsekonse padziko lapansi kuti akomane ndi chitukuko cha msika wa RF PCB, tili ndi chidziwitso chambiri pakupanga PTFE PCB yama board angapo a HF, titha kusunthira pang’onopang’ono ndi kupanga voliyumu. Omwe amatigulitsa teflon amatipatsa monga: Rogers PCB, Nelco PCB, Taconic PCB, Arlon PCB.

Kuwongolera kwakukulu kuma RF osindikizidwa

RF ndi Mircowave PCB kapangidwe

Ma PCBS amakono amaphatikiza matekinoloje osiyanasiyana a digito komanso osakanikirana, chifukwa chake mapangidwe ndi kapangidwe kake kumakhala kovuta kwambiri, makamaka pamene rf ndi microwave zasakanikirana ndizinthu zazing’ono. Kaya mumagwira ntchito nafe, wogulitsa wina wa RF PCB, kapena mupangire RF PCB yanu, pali zifukwa zingapo.

Choyamba ndikuti mafupipafupi a RF nthawi zambiri amakhala 500 MHz mpaka 2 GHz, koma mapangidwe pamwamba pa 100 MHz nthawi zambiri amawonedwa ngati RF PCBS. Ngati mungayende kupitirira 2 GHz, muli mumayendedwe amayikirowevu.

Mapangidwe a RF ndi ma microwave PCB ali ndi zosiyana zazikulu – kusiyana pakati pawo ndi digito yanu yoyendera digito kapena analogi.

Mwachidule, ma board osindikizidwa a RF amagwiritsa ntchito zizindikilo za analog pama frequency apamwamba kwambiri m’chilengedwe. Chizindikiro chanu cha RF chitha kukhala pama voliyumu aliwonse komanso mulingo wapano munthawi iliyonse, bola ngati chili pakati pamalire anu ochepa.

RF ndi ma microwave osindikizidwa ma board transmitter amatulutsa zikwangwani pafupipafupi komanso mkati mwa bandi yama frequency. Zosefera za Bandpass zimagwiritsidwa ntchito kutumiza ma siginolo mu “band of interest” ndikuwonetseratu zisonyezo zilizonse kunja kwa mafupipafupi. Bungweli limatha kukhala locheperako kapena lotambalala ndipo limatha kufalikira ndi wonyamula pafupipafupi.
