1. 5G imvamisa high kwemvelo futhi imvamisa high wesifunda ibhodi
Imvamisa High ukusetshenziswa ezisetshenziswa umphakathi yokuthuthukisa kuletha imvamisa high ephrintiwe wesifunda ibhodi demand.A Eminyakeni embalwa edlule, amasignali ephezulu imvamisa ngenhla 1GHz yagcinwa ezindaweni ezifana Aerospace satellite communications.The intuthuko okusheshayo nobuchwepheshe bezokuxhumana, ukwenza yokuqala zokuxhumana civil imvamisa avele liyaphithizela, plus abanye ibutho lempi kancane kancane wakhala empini, ukuthuthukiswa ezisetshenziswa umphakathi imvamisa high ukuxhumana etholwe okungavamile speed.At samanje, imikhiqizo electronic ulwazi baye bengena enkathini ephezulu imvamisa GHz, futhi the high-imvamisa nokunye ukuxhumana, emelelwa microwave, ukuletha imvamisa high ephrintiwe wesifunda ibhodiizidingo.
Microwave kuchazwa njenganoma nombono ka 1m ~ 0.1mm futhi lunikeza imvamisa uhla 300MHZ ~ 3000GHZ (1GHZ = 1000MHZ) ibizwa ngokuthi microwave.The microwave ngokuvamile ihlukaniswe ngamaviyo amane: decimeter, isentimitha wave milimitha-wave kanye submillimeter wave.In Empeleni, kudingeka ukukhokhela ukunakekelwa okukhethekile ukuze band microwave, ngenxa 5G esizayo, ukushayela ezizimele, zasendlini zokuxhumana ultra-high speed, futhi short-ibanga ultra-high-speed imishini yezokuxhumana engenazo izintambo kukonke band microwave.
2. Imvamisa High wesifunda ibhodi kuyoba omunye izindawo ezanda ngokushesha electronics umkhakha
I global PCB umkhakha sizoqhubeka nokuguquguquka ngokuqhubeka e umjikelezo entsha growth.More futhi isicelo innovative more imikhiqizo esibulalayo electronic, sizonikeza ukukhula ngaphezulu emakethe PCB imboni yomhlaba wonke.
Domestic wesifunda ibhodi Inani likhulu, kodwa isabelo ephezulu kanye umkhakha ukubaluleka kungukuthi ifaniswe. Ngo-2017, inani okukhipha ukubaluleka ephrintiwe wesifunda ibhodiumkhakha e China kulindeleke ukuba $ 29.1 billion.In 2020, kuyoba sifinyelele 359 bhiliyoni RMB (15% okuyinto okusezingeni eliphezulu imvamisa ibhodi, elihambisana nathi $ 5,39 billion).
Eminyakeni embalwa ezayo ukuthuthukisa PCB umkhakha China kuyolandela amathuba amaningi: lokuqala, umkhakha uqhubeke ukuze uthumele kanye nokumiswa kwezwe abadumile base ukukhiqizwa PCB ibhizinisi eChina, wenze China PCB umkhakha cluster inzuzo ngeke ukuqhubekisela phambili gqamisa, futhi ngeke ukudala ukukhula ngokushesha kakhudlwana futhi Kutfutfukiswa kwemabhizinisi alabamnyama zasekhaya, ngokusebenzisa abanolaka emakethe ukuncintisana kanye nomphumela ukufunda ukukhuthaza amandla obuchwepheshe nokuphathwa ezingeni kuya izinyathelo ezintsha; Okwesibili, imboni abasafufusa sizonikeza ngaphezulu amathuba ukuthuthukiswa kanye nokwesekwa inqubomgomo sokuthuthukiswa PCB amarhwebo China.Finally, ukuthuthukiswa ngokushesha emakethe umthengi yasekhaya kuzokwandisa ukukhuthaza ukwanda esikalini isicelo emakethe, noma ngezinye izindlela ukushayela ukuthuthukiswa kwe-umfula PCB umkhakha.
3. Kudala 1936, uDkt Paul Eisner owasungula le PCB wesifunda ibhodi ubuchwepheshe ukukhiqizwa, I PCB Elanyatheliswa Circuit Board (Elanyatheliswa Circuit Board) ngokuhamba ezimpilweni zethu kanye ukukhiqizwa Ufake kuzo zonke izici, PCB njengoba yezingxenye ezibaluleke kakhulu electronic, zikagesi ukusekela umzimba, kuyinto esiphathiswa kagesi connection.In eminyakeni yamuva electronic nge-smartphone, ithebhulethi, amadivayisi agqokekayo smart ezifana ukuvelela okusheshayo lomthengi electronics emakethe, ukukhuthaza kakhulu Nezimo Circuit ibhodi FPC (Nezimo Elanyatheliswa Circuit ibhodi) ukuthuthukiswa emakethe. FPC wesifunda nezimo amabhodi esekelwe polyimide noma i-polyester ifilimu base impahla eyenziwe uhlobo enokwethenjelwa, esihle nezimo ephrintiwe wesifunda ibhodi, ne-high density ezintanjeni zikagesi ezinde ezingaphansi, isisindo ekukhanyeni, ukujiya nomzimba omncane, okuhle izici ukugoba ngokobulili.
