Njira ya PCB ya Ceramic Substrate: Kusankha Kwabwino Kwambiri pa Zipangizo Zamagetsi Zamphamvu Kwambiri, Zambiri, komanso Zodalirika Kwambiri
Kafukufuku ndi Kukonzanso ndi Kupanga Ma PCB a Ceramic mu Ma Batch Ang'onoang'ono, Apakatikati, ndi Aakulu ndi Ma Prototypes
Ma PCB a Ceramic ndi zinthu zopangidwa ndi ceramic zomwe zimakhala ndi mphamvu zabwino kwambiri zamakaniko, kutentha, mphamvu zamagetsi, komanso kukana dzimbiri. Zipangizo za ceramic nthawi zambiri zimakhala ndi mphamvu zapamwamba kwambiri zotsutsana ndi kutentha, kukana kugwedezeka kwa kutentha, kukana kugwedezeka, kukana kuwala kwa dzuwa, komanso kukana moto. Chifukwa chake, ma PCB a ceramic ndi abwino kwambiri popanga zida zamagetsi ndi zida zamagetsi zomwe zimagwira ntchito bwino kwambiri mumakampani amagetsi.
Posankha wopanga woyenera, zinthu monga ukatswiri, luso laukadaulo, miyezo ya zida, mtundu wa chinthu, mtengo, ntchito yogulitsa pambuyo pogulitsa, ndi njira zopangira ziyenera kuganiziridwa.
Rich Full Joy ndi kampani yotsogola yopanga zinthu zoyezera ndi chitukuko komanso kupanga ma PCB a ceramic m'magulu ang'onoang'ono, apakatikati, komanso akuluakulu. Kampaniyo ili ndi zida zamakono zopangira zinthu zoyezera ndi ukadaulo, zomwe zimaonetsetsa kuti nthawi yotumizira zinthu ikuyenda mwachangu komanso kuti zinthu zikhale bwino kuti zikwaniritse zofunikira pa kafukufuku ndi chitukuko cha makasitomala. Poganizira kwambiri za "khalidwe lopanda vuto lililonse," kampaniyo imaika patsogolo luso la zinthu ndikugwiritsa ntchito mwayi wamsika.
Nthawi yoperekera chitsanzo: Masiku 7 mpaka 10, ndipo kupanga gulu: Masiku 10 mpaka 15.
Mitundu ya Zida za Ceramic PCB
