10 Ungqimba ENIG FR4 Tg150 PCB
Inani eliphakeme kakhulu lama-PCB
I-Glass Transition Temperature (Tg) ingenye yezinto ezibaluleke kakhulu zanoma iyiphi i-epoxy futhi iyisifunda sezinga lokushisa lapho i-polymer ishintsha kusuka kokuqinile, okokusebenza okuyingilazi kuya kwentofontofo, eyirabha.
Uma izinga lokushisa lokusebenza lifinyelela endaweni yokuncibilika, lokho kusho ukuthi izinga lokushisa lidlula inani le-Tg, isimo sezinto ezibonakalayo ze-PCB sizoshintshwa sisuke ekubeni yingilazi siye kuketshezi, okuzothinta umsebenzi we-PCB.Futhi leli nani lihlobene nokuzinza kobukhulu be-PCB.
Njengenjwayelo, eyenziwe nge-Tg ≥ 170℃ PCB impahla, ebizwa ngebhodi lesifunda eliphrintiwe le-Tg eliphezulu.Ngokuthuthuka okusheshayo kwemboni ye-elekthronikhi, izinto ezisezingeni eliphakeme ze-Tg zisetshenziswa kabanzi kumakhompiyutha, izinto zokuxhumana, izisetshenziswa ezinembile, nezinsimbi, njll.
Ungazihlukanisa Kanjani Izinto Eziphezulu ze-Tg PCB
| Izinto zokwakha | Tg | I-Mot |
| Okuvamile Tg | 130 ℃ | 110 |
| I-Tg emaphakathi | 150 ℃ | 130 |
| High Tg | 170 ℃ | 150 |
| i-polyimide-Ultra high Tg | 260℃ | 240 |
Isicelo Of High Tg PCB
Ukuphakama kwe-Tg, kungcono ukusebenza kokumelana nokushisa kwe-PCB, ukumelana nomswakama, ukumelana namakhemikhali, ukuzinza nezinye izici.
