Li-Ceramic Substrates: Litharollo tse Tsoetseng Pele ka Baetsi ba Ceramic ba Kaholimo

Li-substrate tsa ceramic li hlahile e le karolo ea bohlokoa lisebelisoa tsa elektroniki tsa sejoale-joale, li fana ka thepa e fetang haholo thepa ea setso ea substrate joalo ka silicon le fiberglass. Ka tsoelo-pele ea theknoloji le tlhahiso, li-substrate tsena li nolofalletsa mefuta e fapaneng ea lits'ebetso makaleng a kang lisebelisoa tsa elektroniki tsa motlakase, likoloi, puisano le lisebelisoa tsa bongaka. Li-substrate tsa ceramic li khetholloa ka ho khanna ha tsona mocheso o ikhethang, ho kenya mocheso o phahameng oa motlakase, matla a mechini, le ho hanyetsa mafome le maemo a thata a tikoloho. Sengoloa sena se hlahloba likarolo tse fapaneng tsa li-substrate tsa ceramic, melemo ea tsona e ikhethang, lits'ebetso tsa tlhahiso tse sebelisitsoeng, le tšusumetso ea bahlahisi ba tsoetseng pele ba ceramic ho fetoleng li-substrate tsena hore e be litharollo tse sebetsang hantle.

Li-Ceramic Substrates ke Eng?

Li-ceramic substrates ke lishiti tse tšesaane kapa lipoleiti tse entsoeng ka thepa ea ceramic e kang alumina (Al₂O₃), aluminium nitride (AlN), kapa silicon carbide (SiC). Li sebetsa e le motheo oa lipotoloho tsa elektroniki, tse fanang ka taolo e ke keng ea lekanngoa ea mocheso, ho kenya motlakase, le ho tšoarella tlas'a maemo a feteletseng. Ha ho bapisoa le lisebelisoa tse tloaelehileng tse kang FR4 (fiberglass) kapa silicon, li-ceramic substrates li ipabola lits'ebetsong tse batloang haholo tse kang motlakase oa motlakase le lithelefono, moo ho senya mocheso le botsitso ba motlakase li leng bohlokoa.
