hi technos, in view of reducing all the references on the drawings and procurement doc's I intend to write a kind of general technical spec.for all our pcb-suppliers and sub-assemblers in following manner: * Std's to obtain during Design/Layout:: * IPC-2221, * IPC-2222. * ... during pcb-manufacturing: * IPC-6011, * IPC-6012, * IPC-4101, * IPC-A-600. * ... during pcb-assembling: * J-STD-001, * IPC-A-610. * Default Requirements: * Class 2 * Design-complexity: A * Others: see also IPC-6012, § 1.3.3.1 Do you (pcb-manuf. & -assemblers) would agree in such a pi-pa-po general-spec? Any coments appreciated. Bernhard
