1. 5G frequency phezulu zazivelela aqhelelkileyo ibhodi yesekethe
frequency High ukusetyenziswa kuthuthwa uphuculo kuzisa rhoqo eshicilelweyo ibhodi yesekethe demand.A kwiminyaka embalwa edlulileyo, iimpawu eziphakamileyo-rhoqo ngaphezu 1GHz yagcinwa kwiindawo ezifana aerospace kunye satellite communications.The inkqubela ngokukhawuleza nonxibelelwano, yenza amaza unxibelelwano civil yokuqala ukuvela enabantu abaninzi kakhulu, kunye nenye band emkhosini ngcembe wanika indlela emiphakathini, uphuhliso ezafa unxibelelwano aqhelekileyo ifunyenwe ngokungaqhelekanga speed.At langoku, iimveliso inkcazelo ngekhompyutha oyifake eliphezulu-njalo xesha GHz, kwaye ophezulu rhoqo kunye nezinye unxibelelwano, bemelwe yi microwave, usondeze aqhelelkileyo eshicilelweyo ibhodi yeseketheiimfuno.
Le microwave uchazwa ombala 1m ~ 0.1mm kunye ahambelana rhoqo uluhlu 300MHZ ~ 3000GHZ (1GHZ = 1000MHZ) ubizwa ngokuba microwave.The microwave udla yahlulwe bands ezine: decimeter, sentimitha-lokutshangatshangisa, millimitha-yomtshangatshangiso submillimeter wave.In Enyanisweni, kufuneka sinikele ingqalelo ekhethekileyo microwave band, ngenxa elizayo 5G, uqhuba elizenzekelayo, endlwini unxibelelwano ultra-high speed, kunye ezimfutshane umgama unxibelelwano engenazingcingo ultra-high-speed zonke kwi microwave band.
Ibhodi zeesekethe 2. rhoqo High iza kuba yenye yeendawo ezanda kushishino elektroniki i
jikelele PCB ishishini kuya kuqhubeka ukuba nokuguquguquka kumjikelo entsha growth.More kunye nesicelo esingaphezulu ezintsha iimveliso terminal elektroniki, uza kubonelela ukukhula kwiimarike ngakumbi PCB imboni emhlabeni.
Basekhaya ibhodi yesekethe ixabiso mkhulu, kodwa share isiphelo ophezulu kunye nexabiso kwicandelo hayi ofanayo. Ngowe-2017, ixabiso Iyonke eshicilelweyo ibhodi yesekethekoshishino China kuqikelelwa ukuba $ 29.1 billion.In 2020, iya kufikelela RMB 359 ezigidi (15% yayo ibhodi aqhelelkileyo, ulungelelene kuthi $ 5,39 billion).
Kwiminyaka embalwa ezayo kuphuhliso lwamashisini PCB China iya kuzisa amathuba amaninzi: okokuqala, kushishino kuqhubeka ukudlulisela kunye nokusekwa ihlabathi edumileyo kwisiseko semveliso PCB lwamashishini eTshayina, ukwenza China iklasta ishishini PCB iadvanteji iya qhubela bonisa, nawo ukudala ukukhula kakhulu ngokukhawuleza kunye nophuhliso lwamashishini zasekhaya, ngenxa ukhuphiswano emarikeni komsindo neziphumo zokufunda ukukhuthaza amandla yobuchule inqanaba lolawulo ukuya amanyathelo amatsha; Okwesibini, uphuhliso lwamashishini asakhasayo iza kubonelela ngamathuba ophuhliso kunye nenkxaso-nkqubo ukwenzela uphuhliso PCB amashishini China.Finally, uphuhliso olukhawulezayo imarike yabathengi zasekhaya ziya kukhuthaza nangakumbi kukwandiswa isikali yesicelo zemarike, kwaye ngokungangqalanga ukuqhuba uphuhliso kushishino PCB umfula.
3. Ukususela ngowe-1936, uGqr Paul Eisner basungula PCB ibhodi yesekethe kubuxhakaxhaka bokuvelisa, Le PCB Circuit Ishicilelwe Board (Ishicilelwe Circuit Board) apha ekuhambeni ubomi bethu kunye nemveliso baye bangena kuzo zonke iinkalo, PCB njengoko yeendima ezibalulekileyo elektroniki, nezombane ukuxhasa umzimba, nguye othwala kwiminyaka elektroniki yakutshanje zombane connection.In kunye efowuni, tablet, izixhobo smart wearable ezifana kukunyuka imalike elektroniki yabathengi, ukukhuthaza kakhulu Flexible Circuit ibhodi FPC (ibhodi Flexible Ishicilelwe Circuit) ophuhliso kwimakethi. FPC iibhodi circuit bhetyebhetye esekelwe izinto polyimide okanye ipholiyesta ifilim isiseko esenziwe uhlobo kukuthembeka ophezulu, elihle bhetyebhetye eshicilelweyo ibhodi yesekethe, kunye ezixineneyo ingcingo, ubunzima ukukhanya, ubukhulu obhityileyo, ukugoba neempawu zesini elungileyo.
