If it's a red mark in the laminate, it will be the laminate manufacturers mark. If it is let me know and I'll try and find who's it is.

Is it a heat rating or a manufacturer's mark? There are not too many companies with names beginning with an F. Any help would be appreciated ... Ultimately I am looking for the manufacturer of an automobile board or assembler.
