Can some one tell me the IPC standard for the tolerance on a .125dia tooling hole used for ATE\ICT testing that is located in a board in diagonal corners dimensioned from the 0,0 datum.... I'm under the impression that it is +.002/-.000... Would I be correct, if so where could I find this in writing... I have IPC-2221, but I can't find it in there no where.... Please help...
