FR4 Epoxy Fiber Glass Sheet
Name : FR4 epoxy fiber glass sheet
Color:light green
ShapesInclude: Sheets
Define and purpose
Thislaminated product is formed through heat pressing after electric industryalkali glass cloth dips into
theepoxy resin. It has high mechanic and dielectric performance, applicable asinsulation
structural components forelectromechanical/electrical equipment, as well as used under dampenvironmental conditions and in oil of transformer. And it can Withstand a variety of chemicalsolvents and acid erosion.
Technical requirement for surface
Thesurface shall tidy and smooth, bubble, impurity are not allowed. But slight scratchand color punctum are allowed. Edge is to be cut smooth. The delamination andcrackle on
the end surface are notallowed .
