1 PURPOSE
The purpose of this Standard is to establish acceptable
principals and practices for dimensioning and tolerancing
used to define end-product requirements for printed boards
and printed board assemblies.
1.1 Scope This Standard covers dimensioning and tolerancing
of electronic packaging as it relates to printed
boards and the assembly of printed boards. The concepts
defined in this Standard are derived from ASME Y14.5M-
1994. Printed boards have such wide applications that there
may be times where this standard does not address a specific
case. In those cases, the user is referred to ASME
Y14.5M 1994 for use of additional dimensioning and tolerancing
concepts.
1.2 General This Standard covers dimensioning, tolerancing,
and related practices for use on printed board drawings
and in related documents. Uniform practices for stating
and interpreting these requirements are established
herein.
