10 Lera ENIG FR4 Tg150 PCB
Tg PCB e phahameng
The Glass Transition Temperature (Tg) ke e 'ngoe ea lintho tsa bohlokoa ka ho fetisisa tsa epoxy leha e le efe 'me ke sebaka sa mocheso moo polymer e fetohang ho tloha ho lintho tse thata, tse kang khalase ho ea nthong e bonolo, ea rabara.
Ha mocheso o sebetsang o fihla sebakeng sa ho qhibiliha, ho bolela hore mocheso o feta boleng ba Tg, boemo ba thepa ea PCB bo tla fetoloa ho tloha ho khalase ho ea ho metsi, e leng se tla ama mosebetsi oa PCB.'Me boleng bona bo amana le botsitso ba tekanyo ea PCB.
Joalo ka tloaelo, e entsoe ka thepa ea Tg ≥ 170℃ PCB, e bitsoang boto e phahameng ea Tg e hatisitsoeng.Ka nts'etsopele e potlakileng ea indasteri ea lisebelisoa tsa elektroniki, lisebelisoa tse phahameng tsa Tg li sebelisoa haholo likhomphutha, lisebelisoa tsa puisano, lisebelisoa tse nepahetseng le lisebelisoa, joalo-joalo.
Mokhoa oa ho Khetholla Lisebelisoa tse Phahameng tsa Tg PCB
| Lisebelisoa | Tg | Mot |
| Tg e tloaelehileng | 130 ℃ | 110 |
| Tg e mahareng | 150 ℃ | 130 |
| Phahameng Tg | 170 ℃ | 150 |

Tšebeliso ea High Tg PCB
E phahameng ea Tg, e ntlafatsa ts'ebetso ea PCB ea mocheso, ho hanyetsa mongobo, ho hanyetsa lik'hemik'hale, botsitso le litšobotsi tse ling.
