Kopo
Boleng ba TG bo bolela mocheso oa phetoho ea khalase (Tg), e leng parameter ea bohlokoa bakeng sa botsitso ba mocheso le ho hanyetsa mocheso oa liboto tsa PCB.Liboto tsa PCB tse nang le boleng bo fapaneng ba TG li na le thepa e fapaneng le maemo a ts'ebeliso.Liphapang tse tloaelehileng ke tsena:
1. Ha boleng ba Tg bo phahame, ho molemo ho hanyetsa mocheso o phahameng oa boto ea PCB, e loketseng maemo a kopo libakeng tse phahameng tsa mocheso, tse kang lisebelisoa tsa elektronike tsa likoloi, taolo ea indasteri le masimo a mang.
2. Ha boleng ba Tg bo phahame, lisebelisoa tsa mochine tsa PCB li betere, 'me matšoao a matla a kang ho kobeha, ho tsitsa, le ho kuta a molemo ho feta a boto ea PCB e nang le boleng bo tlaase ba Tg.E loketse lisebelisoa tse nepahetseng le lisebelisoa tse hlokang botsitso bo phahameng.
3. Litsenyehelo tsa liboto tsa PCB tse nang le boleng bo tlaase ba Tg li batla li le tlaase, tse loketseng maemo a mang a kopo a nang le litlhoko tse tlaase tsa ts'ebetso le taolo e thata ea litšenyehelo, tse kang lisebelisoa tsa elektronike tsa bareki.Ka bokhutšoanyane, ho khetha boto ea PCB e loketseng boemo ba hau ba kopo ho tla thusa ho ntlafatsa boleng ba sehlahisoa le botsitso le ho fokotsa litšenyehelo tsa tlhahiso.
4. Boto ea potoloho e hatisitsoeng ea tg150 e bolela boto ea potoloho e entsoeng ka boto ea tg150.Hangata TG e fana ka maikutlo a mocheso oa phetoho ea khalase, e bolelang phetoho e tsitsitseng ea thepa ea amorphous ho tloha boemong bo tiileng le "khalase" ho ea boemong ba rabara le bo hlakileng ha ho sebelisoa mocheso o phahameng ho feta kamoo ho neng ho lebelletsoe.Le ha TG hangata e ipaka e le tlase ho feta mocheso o qhibilihang oa boemo bo lumellanang ba kristale.
5. Thepa ea mocheso oa mocheso oa mocheso oa khalase hangata e tla e le lisebelisoa tse sa cheng, tse sothehileng / tse qhibilihang ka mekhahlelo e itseng ea mocheso.Tg150 PCB e tla e le thepa ea TG e mahareng hobane e oela kaholimo ho likhato tse 130 ho isa ho tse 140 empa e le ka tlase ho likhato tse 170 tsa Celsius kapa ho feta.Ka kopo hlokomela hore TG e phahameng ea substrate (hangata epoxy), e phahamisa botsitso ba boto ea potoloho e hatisitsoeng.
FAQs
Mocheso o hlokahalang bakeng sa ho tiea ha PREPREG o tlameha ho sebelisoa ntle le ho feta FR4 Tg ho boloka botsitso ba PCB.Tg e tloaelehileng ea FR4 e pakeng tsa 130 - 140 ° C, Tg e bohareng ke 150 ° C 'me Tg e phahameng e feta 170 ° C.
Tg e tloaelehileng e lula ka holimo ho 130 ℃ ha Tg e phahame ka holimo ho 170 ℃ le Tg e bohareng ka holimo ho 150 ℃.Ha ho tluoa tabeng ea lisebelisoa bakeng sa li-PCB, Tg e phahameng e lokela ho khethoa, e lokelang ho ba holimo ho feta mocheso o sebetsang hona joale.
Tg150 PCB e tla e le thepa ea TG e mahareng hobane e oela kaholimo ho likhato tse 130 ho isa ho tse 140 empa e le ka tlase ho likhato tse 170 tsa Celsius kapa ho feta.Ka kopo hlokomela hore TG e phahameng ea substrate (hangata epoxy), e phahamisa botsitso ba boto ea potoloho e hatisitsoeng.
Ntho e ka sehloohong e lokelang ho nahanoa hore na tšebeliso ea 150 kapa 170 Tg PCB ke mocheso o sebetsang.Haeba e ka tlase ho 130C/140C, joale Tg 150 lintho tse bonahalang e lokile bakeng sa PCB hao;empa haeba mocheso o sebetsang o le haufi le 150C, joale o tlameha ho khetha 170 Tg.
Tg PCB e phahameng e na le sistimi ea resin e etselitsoeng ho mamella ho soasoa ntle le loto le ho nolofaletsa matla a phahameng a mochini libakeng tse thata, tse phahameng tsa mocheso.Resin e bolela ntho efe kapa efe e tiileng kapa e semisolid e sebelisoang hangata ho lipolasetiki, li-varnish, joalo-joalo.
