13.3.2.3-3 Packaging a Circuit as a Single Terminal-Board or Plug-In Module

When circuit packaging is used to modularize digital equipment, the circuit should be packaged as a single terminal board or plug-in module, when possible, to support its testing and installation.

Additional Information:
Providing a single board or module reduces the number of parts that must be handled and reduces the likelihood of errors during handling, testing, and installation.
