Daim duab
Lub 4 Txheej presped ncig stackup yog muaj 3 ntawm tib txheej thiab hauv av txheej ua nws4 txheej hauv tag nrho.
Tag nrho cov khaubncaws sab nraud povtseg yog siv rau kev coj ua ntawm cov cim.
Lub FRST ob lub pas dej sab hauv sab hauv qhov tseem ceeb thiab feem ntau siv tau raws li lub zog panes lossis tau hais txog raws li kev coj ua ntawm cov cim.
Cias hais lus 4-txheej pcb stackup yog muaj 2 ntawm cov singlea VCC thiab ib txheej av txheej.
Cov ntsiab lus tseem ceeb rau kev yuav pcb
Cov neeg yuav khoom hluav taws xob feem ntau hluav taws xob tau tsis meej pem txog tus nqi ntawm PCBs. Txawm tias qee cov neeg uas muaj ntau xyoo ntawm kev paub hauv PCB kev ua tiav tej zaum yuav tsis nkag siab txog lub qub vim li cas. Qhov tseeb, tus nqi PCB yog tsim los ntawm cov hauv qab no:
Ua ntej, tus nqi sib txawv vim cov khoom sib txawv siv hauv PCB.
Noj ob chav zoo dog dig txheej pcb ua piv txwv, tus Laminate txawv los ntawm Fr-4, Khar-3, thiab lwm yam nrog rau 0.2 hli rau 3.6mm. Lub thickness ntawm tooj liab txawv ntawm 0.5oz rau 6oz, txhua yam uas ua rau tus nqi loj loj. Tus Soldenmask Ink tus nqi kuj txawv ntawm ib txwm thermosetting ink khoom thiab cov duab ntsuab ntsuab hauv cov khoom siv.
Thib ob, tus nqi sib txawv vim muaj cov txheej txheem sib txawv.
Cov txheej txheem sib txawv ntau lawm ua rau cov nqi sib txawv. Xws li Pawg Thawj Coj Kub-Plated thiab Tin-Plated Board, cov duab ntawm cov kab sib tw thiab cov duab lo lo ntxhuav kev yuav tsim cov nqi sib txawv, ua rau cov nqi sib txawv.
