Gawd. Sure FR-4 will meet those conditions. Tg [check the fine SMTnet Archives for discussion on Tg] of FR-4 is 130�F or so. Consider: * Is the delT between Tg and the upper operating [or storage] temperature acceptable for your application? * D

I agree with Wolfgang that a check list, like he proposes, is very useful in evaluating your ability to assemble products. No sense designing a 16 inch board if the throat of your wave is 15 inches. Taking a different tact � what if you define your
