I have a customer for a high rel application that is concerned about weave exposure on a epoxy glass stiffener.
According to IPC-610, weave exposure is not acceptable. Our material supplier sands the material in order to meet tight thickness tolerances. Per IPC-6013, stiffeners are to be evaluated only for mechanical support. In addition, the circuit as supplied is allowed weave exposure if conductor spacing is not reduced below minimum. Since a stiffener carries no conductors, I would consider this a non-issue.
Any words of wisdom from manufacturers or assemblers welcome.
