Hello group, An interesting question came up about validating printed circuit board raw material. In searching for alternate vendors we provide a spec that V-0 material is required and a UL V-0 stamp be placed on the board. The question is, how do I independently validate the material used, since a vendor could theoretically choose whatever they want and stamp it as V-0? -doug Douglas E.
