1. 5G mkulu pafupipafupi kusanduka ndi mkulu pafupipafupi dera bolodi
High pafupipafupi wamba ntchito Mokweza kumabweretsa mkulu pafupipafupi kusindikizidwa dera bolodi demand.A zaka zingapo zapitazo, chizindikiro mkulu-pafupipafupi pamwamba 1GHz anali sachoka m'madera monga Azamlengalenga ndi Kanema communications.The patsogolo mofulumira zotumizira, kupanga choyambirira kulankhulana yapachiweniweni pafupipafupi kuoneka wadzadza kwambiri, kuphatikiza ena asilikali pang'onopang'ono anagwetsa wamba, chitukuko cha wamba aya mkulu pafupipafupi analandira zapadera speed.At pano, zamagetsi mudziwe mankhwala talowa mkulu-pafupipafupi nthawi ya GHz, ndipo mkulu-pafupipafupi ndi mauthenga ena, kudzera mwa mayikirowevu, kubweretsa mkulu pafupipafupi kusindikizidwa dera bolodizofunika.
mayikirowevu The amatanthauziridwa kuti timaganiza za 1m ~ 0.1mm ndi lolingana pafupipafupi osiyanasiyana 300MHZ ~ 3000GHZ (1GHZ = 1000MHZ) amatchedwa microwave.The mayikirowevu kawirikawiri kugawidwa m'magulu anayi: decimeter, centimeter-yoweyula millimeter-yoweyula ndi submillimeter wave.In Ndipotu, tiyenera kulipira mwapadera kwa mayikirowevu gulu, chifukwa cha 5G m'tsogolo, yoyenda yokha galimoto, m'nyumba kopitilira muyeso-mkulu liwiro kulankhulana ndi yochepa mtunda kopitilira muyeso-mkulu-liwiro kulankhulana mafoni onse mu mayikirowevu gulu.
2. Mkulu pafupipafupi dera bolodi ndi imodzi mwa madera kukula yachangu makampani zamagetsi
padziko lonse PCB makampani adzapitiriza kusintha mu mkombero watsopano growth.More ndi ntchito zambiri nzeru katundu osachiritsika pakompyuta, adzapereka kwambiri kukula msika PCB makampani padziko lonse.
M'banja dera bolodi mtengo waukulu, koma mkulu-mapeto gawo ndi phindu makampani si chikufanana. Mu 2017, chiwerengero mtengo linanena bungwe la kusindikizidwa dera bolodimakampani ku China ikuyembekezeka kukhala $ 29,1 billion.In 2020, lidzafika biliyoni 359 rmb (15% amene ali mkulu pafupipafupi bolodi, lolingana ife $ 5,39 biliyoni).
Mu zaka zingapo zotsatira chitukuko cha mafakitale China PCB adzabweretsa mipata yambiri: choyamba, makampani kupitiriza kusamutsa ndi kukhazikitsidwa kwa dziko wotchuka m'munsi PCB ogwira ntchito yopanga ku China, kupanga China PCB makampani limodzi ntchito zidzalimbikitsa yosangalatsa, Inenso kulenga kwambiri mofulumira kukula ndi chitukuko amakampani zoweta, mwa wampikisano msika ndi kuphunzira zotsatira kulimbikitsa mphamvu luso ndi mlingo oyang'anira njira yatsopano; Kachiwiri, chitukuko cha mafakitale akutulukira adzapereka mwayi chitukuko ndi thandizo mfundo za chitukuko cha PCB mabizinezi mu China.Finally, chitukuko mofulumira msika zoweta ogula zidzalimbikitsa kulimbikitsa patsogolo ntchito msika lonse, ndi njira zina kuyendetsa chitukuko cha makampani kumtunda PCB.
3. Monga m'ma 1936, Dr Paulo Eisner anatulukira PCB dera bolodi luso kupanga The Kusindikizidwa Dera Board PCB (Kusindikizidwa Dera Board) mu njira ya moyo wathu ndi kupanga kulowa mbali zonse, PCB monga zigawo zikuluzikulu zofunika pakompyuta, zigawo pakompyuta kuthandiza thupi, ndi chotengera cha magetsi connection.In zaka pakompyuta posachedwapa ndi foni ndi, piritsi, wearable zipangizo wochenjera monga kuwuka mofulumira msika ogula zamagetsi, kwambiri kulimbikitsa Ololera dera bolodi FPC (Ololera Kusindikizidwa dera bolodi) msika chitukuko. FPC kusintha dera matabwa nkhani polyimide kapena poliyesitala filimu m'munsi anapanga mtundu wa kudalirika mkulu, kwambiri kusintha kusindikizidwa dera bolodi, ndi osalimba mkulu wa Kulumikizana, kulemera kuwala, makulidwe woonda, chabwino kupinda makhalidwe kugonana.
