Abstract

Scope: This document is intended to assist in selecting the test analyzer, test parameters, test data, and fixturing required to perform electrical test(s) on all unpopulated printed boards. The testing of printed boards with embedded components (e.g., resistors, capacitors, etc.) is not addressed in this document revision. Purpose Electrical testing verifies that the conductive networks on the printed boards are interconnected according to the design requirements. Electrical test does not ensure that the printed board can be assembled or that the printed board meets all of the customer’s requirements. Many physical characteristics of the conductors (dimensional accuracy, solder mask, conductor geometry and nomenclature registration, presence of holes, etc.) can’t be determined by electrical test. Other checks should be employed to confirm these characteristics.
