1. 5G yakakwirira Frequency shanduka uye yakakwirira Frequency redunhu bhodhi
High maitikiro rehurumende kushandiswa ndiwedzere kunounza yakakwirira maitikiro akadhindwa redunhu bhodhi demand.A makore mashoma apfuura, mukuru-kakawanda anonongedzera pamusoro 1GHz vakanga muchisungwazve kunzvimbo dzakadai Aerospace uye kuongorora communications.The nokukurumidza mberi yekufambisa, kuti chepakutanga vehurumende kukurukurirana maitikiro kuonekwa ungana chaizvo, pamwe vamwe uto bhendi zvishoma nezvishoma akasvimha rehurumende, budiriro kwevanhuwo zvavo mukuru maitikiro kukurukurirana vakawana kunoshamisa speed.At chipo, yemagetsi mashoko zvigadzirwa mapinda mukuru-kakawanda nguva GHz, uye mukuru-kakawanda uye dzimwe kukurukurirana, inomiririrwa microwave, kuunza yakakwirira Frequency akadhindwa redunhu bhodhizvinodiwa.
The microwave rinorondedzerwa so wavelength kuti 1M ~ 0.1mm uye runoenzanirana kakawanda kuwanda 300MHZ ~ 3000GHZ (1GHZ = 1000MHZ) anonzi microwave.The microwave rinowanzoshandiswa rakakamurwa mapoka mana: decimeter, sendimita-wave, millimeter-wave uye submillimeter wave.In chokwadi, tinofanira kubhadhara ngwariro chaiyo microwave bhendi, nekuda ramangwana 5G, zvionera dzokutyaira, indoor Ultra-soro nokukurumidza muchikurukurirana, uye pfupi-daro Ultra-soro-nokukurumidza kukurukurirana pasina tambo zvose vari microwave bhendi.
2. High Frequency redunhu bhodhi ichava chimwe kukurumidza kuwedzera munzvimbo dziri zvemagetsi indasitiri
The yose pcb Indasitiri acharamba ichishanduka munyika itsva kutenderera growth.More uye zvikuru itsva kushanda chinouraya zvemagetsi zvigadzirwa, achapa zvakawanda musika kukura nokuda pcb indasitiri pose.
Domestic redunhu bhodhi mutengo wakakura, asi mukuru-kuguma mugove uye maindasitiri ukoshi havasi vachiwirirana. Muna 2017, zvachose goho kukosha akadhindwa redunhu bhodhimaindasitiri mu China kunotarisirwa kuti $ 29.1 billion.In 2020, izvozvo kuchasvika rmb mabhiriyoni 359 (15% chiri kumusoro kakawanda bhodhi, zvakafanana kwatiri $ 5,39 billion).
Mumakore mashomanana akatevera kukura China pcb maindasitiri huchaunza nemikana yakawanda: chokutanga, indasitiri kuramba uchatamisa uye kugadzwa nyika akakurumbira pcb zvebhizimisi kugadzirwa chawo muna China, kuti China pcb indasitiri sumbu Muchabatsirweiko vange kunoratidzei, uyewo chido sika zvimwe anomhanya kukura mudzimba emakambani, kuburikidza kunotyisa kumusika makwikwi uye kudzidza kushanda kusimudzira hwokugadzira simba uye kutarisirwa pamwero kuti nhanho itsva, Chechipiri, kukura zvichiitika maindasitiri ichapa zvakawanda kukura mikana uye rutsigiro mutemo nokuda kukura pcb emakambani ari China.Finally, kukurumidza kukura zvezvipfuwo nevatengi musika yatichawana pave pakuwedzera chikumbiro musika scale, uye zvisina kunanga kutyaira kukura nechokumusoro kwerwizi pcb indasitiri.
3. Kare 1936, Dr Paul Eisner akazogadzira pcb redunhu bhodhi kugadzirwa michina, The Printed Circuit Board pcb (Printed Circuit Board) mukufamba hwedu uye kugadzirwa kupinda zvose zvinhu, pcb sezvo inokosha zvemagetsi zvinoriumba, zvemagetsi zvinoriumba kutsigira muviri, ndiye mutakuri zvigadzirwa zvemagetsi connection.In achangopfuura makore ane smartphone, piritsi, wearable akangwara mano akadai, zvikuru kutsigira Zvichienderana Circuit board kukurumidza kuwedzera nevatengi zvemagetsi musika FPC (Zvichienderana Printed Circuit board) musika kukura. FPC tefa redunhu mapuranga kwakavakirwa polyimide kana polyester firimu chawo zvinhu wakaitwa mhando dzakakwirira rakavimbika, chakanakisisa kusanduka akadhindwa redunhu puranga, pamwe mukuru arambe achirema ose wiring, chiedza uremu, mutete ukobvu, vakafugama zvakanaka pabonde maitiro.
