Q. Ke mekhoa efe ea moralo e thusang ho fokotsa litaba tsa mocheso ka li-PCB tsa indasteri?

Sebopeho se hlokolosi sa likarolo, lifofane tsa koporo tse inehetseng ka hare e le licheso tsa mocheso, li-vias tsa mocheso tlas'a likarolo tse chesang, li-screw terminals le liforeimi tsa mocheso li thusa ho tsamaisa mocheso hole le li-PCB tsa indasteri.

Q. Ke likhetho life tse ntle tsa substrate bakeng sa li-PCB tsa indasteri?

FR-4, Tg e phahameng FR-4, PTFE, PTFE e tletseng ka ceramic e fana ka matla a babatsehang a mochine, ho hanyetsa mocheso, ho se sebetse ha lik'hemik'hale le matla a dielectric a hlokahalang.

Q. Ho tšepahala ho fapana joang pakeng tsa li-PCB tsa indasteri le tsa khoebo?

Li-PCB tsa indasteri li etsa liteko tse potlakileng tsa bophelo bohle le tlhahlobo ea ho chesa ho ntlafatsa ts'epahalo ea tšimo. Litefiso tsa FIT tsa <50 ho isa ho <10 lia batloa bakeng sa lits'ebetso tse bohlokoa haholo.

Q. ke mekhoa efe ea masela e sebelisetsoang ho ntlafatsa boleng ba PCB ba indasteri?

Litaolo tse matla tsa ts'ebetso, lits'ebetso tsa setifikeiti sa UL, tlhahlobo e pharaletseng e sebelisang li-coupons tsa liteko le AOI, tlhahlobo ea khatello ea maikutlo le liteko tse matla li thusa ho netefatsa boleng ba PCB ea indasteri.
