4'x8' Fr4 Sheet for Sale
Description
This product is a kind of laminated board formed through heat
pressing after the electric industry fiolax cloth dips into epoxy
resin. It is suitable as the mechanical, electric and electronic
insulation structural components which are used under room and
middle temperatures with a certain mechanical performance and
electric performance requirement.
