10 Txheej ENIG FR4 Tg150 PCB
High Tg PCB
Iav Transition Temperature (Tg) yog ib qho tseem ceeb tshaj plaws ntawm ib qho epoxy thiab yog thaj tsam kub uas cov polymer hloov ntawm cov khoom siv tawv, iav mus rau cov khoom muag muag, rubbery.
Thaum qhov kub thiab txias ua hauj lwm mus txog qhov melting point, uas txhais tau hais tias qhov kub siab tshaj Tg tus nqi, cov xwm txheej ntawm cov khoom siv PCB yuav raug hloov los ntawm glassy mus rau kua, uas yuav cuam tshuam rau kev ua haujlwm ntawm PCB.Thiab tus nqi no cuam tshuam nrog kev ruaj ntseg ntawm PCB qhov ntev.
Raws li niaj zaus, ua nrog Tg ≥ 170 ℃ cov khoom siv PCB, uas yog hu ua lub siab Tg luam tawm Circuit Board.Nrog rau txoj kev loj hlob sai ntawm kev lag luam hluav taws xob, cov khoom siv Tg siab yog dav siv hauv computers, khoom siv sib txuas lus, cov cuab yeej meej, thiab cov twj paj nruag, thiab lwm yam.
Yuav ua li cas kom paub qhov txawv siab Tg PCB cov ntaub ntawv
| Khoom siv | Tg | Mot |
| Ordinary Tg | 130 ℃ | 110 |
| Medium Tg | 150 ℃ | 130 |
| Siab Tg | 170 ℃ | 150 |
| polyimide-Ultra siab Tg | 260 ℃ | 240 |
Daim ntawv thov High Tg PCB
Qhov siab dua ntawm Tg, qhov zoo dua ntawm kev ua haujlwm ntawm PCB tshav kub tsis kam, noo noo tsis kam, tshuaj tiv thaiv, stability thiab lwm yam ntxwv.
