High Tg board

Ha mocheso oa boto ea potoloho e phahameng ea Tg e nyolohela sebakeng se itseng, substrate e tla fetoha ho tloha "boemo ba khalase" ho ea "boemo ba rabara", 'me mocheso ka nako ena o bitsoa mocheso oa phetoho ea khalase (Tg) ea poleiti.Ka mantsoe a mang, Tg ke mocheso o phahameng ka ho fetisisa (℃) oo substrate e lulang e tiile.Ka mantsoe a mang, lintho tse tloaelehileng tsa PCB substrate mocheso o phahameng ha li hlahise feela ho nolofatsa, deformation, ho qhibiliha le liketsahalo tse ling, empa hape li bontša ho fokotseha ho hoholo ha thepa ea mechine le ea motlakase (ha ke nahane hore u batla ho bona lihlahisoa tsa bona li hlaha tabeng ena. ).

Lipoleiti tse akaretsang tsa Tg li feta likhato tse 130, Tg e phahameng hangata e feta likhato tse 170, 'me Tg e mahareng e ka ba likhato tse fetang 150.

Hangata, PCB e nang le Tg≥170℃ e bitsoa boto e phahameng ea Tg.

Tg ea substrate e eketseha, 'me ho hanyetsa mocheso, ho hanyetsa mongobo, ho hanyetsa lik'hemik'hale, ho hanyetsa botsitso le litšobotsi tse ling tsa boto ea potoloho li tla ntlafatsoa le ho ntlafatsoa.Ha boleng ba TG bo phahame, ts'ebetso ea ho hanyetsa mocheso ea poleiti e tla ba betere.Haholo-holo ts'ebetsong e se nang loto, hangata TG e phahameng e sebelisoa.

Tg e phahameng e bolela ho hanyetsa mocheso o phahameng.Ka tsoelo-pele e potlakileng ea indasteri ea elektronike, haholo-holo lihlahisoa tsa elektronike tse emeloa ke lik'homphieutha, ho lebisa nts'etsopele ea mosebetsi o phahameng, multilayer e phahameng, tlhokahalo ea thepa ea PCB substrate e phahameng ho hanyetsa mocheso e le tiiso ea bohlokoa.Ho hlaha le nts'etsopele ea theknoloji e phahameng ea ho kenngoa ha methapo e emetsoeng ke SMT le CMT e etsa hore PCB e itšetlehe haholo ka tšehetso ea mocheso o phahameng oa mocheso oa substrate ho latela sebaka se senyenyane sa aperture, wiring e ntle le mofuta o mosesaane.
