Printed Circuit Boards (PCBs) tuaj yeem muab faib ua ntau hom raws li lawv cov qauv, cov khoom siv, thiab kev siv. Qhov kev faib tawm feem ntau yog los ntawm cov txheej txheem, suav nrog ib zaug -sab, ob - sab, thiab ntau txheej txheej. Ib leeg-ib sab boards tsuas muaj ib txheej ntawm cov ntawv ci tooj liab, uas ua rau cov qauv yooj yim thiab tus nqi qis, feem ntau siv hauv cov khoom siv hluav taws xob xws li lub laij lej, chargers, thiab cov khoom siv me me. Ob chav - sab boards muaj cov kab hluav taws xob ntawm ob sab, txuas nrog vias, tso cai rau kev tsim hluav taws xob ntau dua thiab tau siv dav hauv kev tswj hwm kev lag luam, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob. Multilayer boards muaj ntau yam conductive thiab insulating cov khaubncaws sab nraud povtseg nyob rau hauv, ua kom siab dua - xov hlau ceev thiab ruaj khov dua cov teeb liab; tam sim no lawv tau dav siv nyob rau hauv siab -kawg teb xws li computer motherboards, cov khoom siv sib txuas lus, automotive electronics, thiab servers.
Raws li cov khoom siv thiab cov qauv hloov tau yooj yim, PCBs kuj tuaj yeem muab faib ua cov laug cam, cov boards hloov tau, thiab nruj -flex boards. Rigid boards tam sim no yog hom siv dav tshaj plaws, feem ntau yog ua los ntawm FR-4 iav fiber ntau cov khoom, muab cov khoom siv zoo thiab ruaj khov. Flexible printed circuit boards (FPCs) yog tsim los ntawm cov khoom siv tau yooj yim xws li polyimide (PI), ua rau lawv tuaj yeem khoov, quav, thiab txawm txav mus los. Lawv feem ntau siv nyob rau hauv qhov chaw- txwv cov khoom xws li kev sib txuas ntawm lub xov tooj ntawm tes, lub koob yees duab modules, thiab cov khoom siv hnav. Rigid-flex boards ua ke nrog kev ruaj ntseg ntawm cov boards nruj nrog kev hloov pauv ntawm cov boards hloov tau, txo cov naj npawb ntawm cov khoom sib txuas thiab txhim kho kev ntseeg tau tag nrho. Yog li ntawd, lawv tau siv ntau dua hauv aerospace, khoom siv kho mob, thiab high-end ntse terminals.
