IPC D-356B – Bare Substrate Electrical Test Data Format

This standard describes a data format for transmitting bare board electrical test information in digital form, including data suitable for computer-aided repair. When used as a netlist input to test data processing, the receiver of IPC-D-356B data will determine test point assignments and positioning. Enhancements to the B Revision include updates to the concept of testable areas to account for SMD pads and unusually shaped pads, updating of complex records for representing all inter-layer connections in nets, a simple polygon description format that improves graphical representation of the bare board, and new methods for identifying endpoints and midpoints.
