Epoxy iav fiber ntau qws FR4
Epoxy iav fiber ntau qws FR4
Cov khoom no yog ua los ntawm epoxy resin thiab iav ntaub. Tus qauv yog 3240. Nws muaj kev ua haujlwm siab ntawm kev ua haujlwm siab ntawm qhov nruab nrab kub thiab ruaj khov hluav taws xob ua haujlwm ntawm qhov kub thiab txias. Nws yog qhov tsim nyog rau cov khoom siv hluav taws xob zoo rau cov tshuab, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, nrog cov khoom siv hluav taws xob zoo thiab cov khoom siv hluav taws xob, cov cua sov zoo thiab cov dej tsis zoo. Thaum tshav kub kub-resistant chav B (155 degrees).
