FR4 Epoxy Laminate:-

This is the standard laminate used in our sector of the industry. We carry stocks of all the main variants. The standard thickness used is 1.8mm, copper thickness is 35 microns

Its closely related to FR5 which is the old high temperature version, but has now been replaced by the more common BT Epoxy type

Product specification

please note: image shown in common pcb in diff sizes. u will recv the material as per item title and des.
