Subject: [TN] WARPGreetings,Has anyone out there had experience with these so-called "de-warp" chambers. I have a large quantityof double sided boards(.062/140Tg) that have severe warp with memory. We have performed "dewarp" (three hours at 300F then cooling to ambient temperature under weight)baking using press caul plates several times with no success. The panels have even copper distribution side to side.Any help/suggestions would be appreciated.
