Dab tsi yog pawg-up?
-Up yog hais txog kev npaj ntawm tooj liab txheej thiab insulating txheej uas ua rau pcb ua ntej cov qauv tsim. Thaum ib txheej txheej-puag?
• Ib qho pcb txheej pcb tuaj yeem pab koj txo koj cov hluav taws xob qhov hluav taws xob rau sab nraud thiab txo cov kev cuam tshuam thiab kev sib tw ntawm cov kab mob siab pcb layouts.
• Ib qho zoo txheej pcb stack class tuaj yeem pab koj sib npaug rau cov txheej txheem pheej yig, cov qauv tsim kev lag luam uas muaj kev txhawj xeeb txog cov cim qhia ncaj ncees
• Ib qho txoj cai PCB txheej tuaj yeem txhim kho lub tshuab hluav taws xob hluav taws xob tau zoo ntawm koj tus qauv tsim thiab.
Nws yuav ntau zaus yuav tau txais koj cov txiaj ntsig los nrhiav cov teeb tsa PCB tau teeb tsa rau koj cov ntawv teev npe ua haujlwm.
Rau cov multilayer PCBs, cov txheej dav suav nrog cov dav hlau dav hlau (grd dav hlau), hluav taws xob hluav taws xob (PWR dav hlau), thiab sab hauv teeb liab txheej txheem. Ntawm no yog ib qho piv txwv ntawm 8-txheej pcb stackup.
Anke PCB muab ntau txheej txheem hluav taws xob cov laug cam ntawm 4μm rau 250μm (0.5oz rau ntawm 0.24μm (0.5oz rau 2oz), thiab qhov tsawg kawg ntawm cov khaubncaws sab nraud povtseg rau 3mil.
