Ndeapi mabasa e FR4 epoxy board?

1. Various forms:

Marezeni akasiyana, anorapa maajenti, uye anogadzirisa masisitimu anogona kupotsa anoenderana nezvinodiwa zvakasiyana-siyana zvekushandisa pafomu, uye huwandu hunogona kubva kubva kuderera zvakanyanya viscosity kusvika kune yakakwira melting point solids.

2. Convenient curing:

Sarudza akasiyana akasiyana ekurapa maajenti, iyo epoxy resin sisitimu inogona kurapa mutembiricha ye0 ~ 180 ℃.

3. Low shrinkage:

Kuita pakati peepoxy resin uye mumiririri wekurapa anoshandiswa anoitwa nekunangana kwekuwedzera reaction kana ring-kuvhura polymerization reaction yemapoka epoxy mumorekuru resin, uye hapana mvura kana zvimwe zvinoputika by-zvigadzirwa zvinoburitswa. Kuenzaniswa neunsaturated polyester resins uye phenolic resins, dzinoratidza kuderera kwakanyanya (pasi pe2%) panguva yekurapa.

4. Strong adhesion:

Iwo echisikigo polar hydroxyl mapoka uye ether zvisungo mune molecular cheni ye epoxy resins inoita kuti inamire zvakanyanya kune zvakasiyana zvinhu. Iyo shrinkage ye epoxy resin yakaderera kana ichirapa, uye kushushikana kwemukati kunogadzirwa kudiki, izvo zvinobatsirawo kuvandudza kusimba kwekunamatira.

5.Mechanical properties

Iyo yakaporeswa epoxy resin system ine yakanakisa mechaniki zvivakwa.
