Printed Wiring for Electronic Equipment (Refer To IPC-D-275 or IPC-2221)

Scope

This standard establishes design requirements governing rigid, single-sided printed-wiring boards, double-sided printed-wiring boards, multilayered printed-wiring boards, printed-wiring assemblies constructed from those boards mentioned above, and design considerations for the mounting of parts and assemblies thereon.  The design criteria (such as electrical spacings) contained in this standard are predicated on the requirement that end item assemblies (circuit card assemblies, printed-wiring assemblies, back planes, mother boards) shall be conformally coated (see 6.3.1).  Conformal coating shall be in accordance with MIL-I-45058.

Classification.  Printed-wiring boards shall be of the types shown, as specified (see 4.2):
Type 1 - Single-sided board
Type 2 - Double-sided board
Type 3 - Multilayer board

Notes

Claudia's Notes:
This standard was originally cancelled in 1995 and replaced by IPC-D-275, "Generic Standard on Printed Board Design."  In 1999, that supersession information was modified to additionally include IPC-2221, "Design Standard for Rigid Printed Boards and Rigid Board Assemblies."
