Multilayer flexible printed circuit board (ML-FPCB) yog lub rooj tsav xwm hauv Circuit Court uas tsim los ntawm cov txheej txheem hloov pauv ntawm cov txheej txheem yooj yim thiab cov txheej txheem txheej txheem, uas yog nws qhov nyias nyias, hloov tau yooj yim, thiab siab - xov hlau.
Tus naj npawb ntawm Cov Txheej Txheem: Feem ntau 2-12 txheej, cov khoom lag luam siab tuaj yeem muaj ntau tshaj 20 txheej, nrog cov txheej txheem sib txawv ntawm 0.05-0.2mm.
Cov ntaub ntawv: Lub substrate yuav tsum yog cua sov-resistant (xws li, PI nrog ib tug kub tsis kam ntawm 260 degree), resistant rau tshuaj corrosion, thiab cov tooj liab ntawv purity yuav tsum ntau tshaj los yog sib npaug rau 99.8% (feem ntau dov tooj liab los yog electrolytic tooj liab).
Cov txheej txheem: Siv cov thev naus laus zis zoo xws li laser drilling (qhov tsawg kawg ntawm lub qhov taub 50μm) thiab lub tshuab nqus tsev lamination (siab 0.5-1.5MPa) kom ntseeg tau tias qhov sib txawv ntawm qhov sib txawv (hauv ± 25μm).
