TESTABILITY GUIDELINES

For The Design Of

PRINTED CIRCUIT BOARDS

 

 

1.0 INTRODUCTION

This document is intended to improve the testability of printed circuit assemblies. This can be achieved by following these guidelines when designing new printed circuit boards.

 

2.0 SCOPE

Circuit design for testability refers to the practice of insuring accessibility and controllability of all components. Test engineers and design engineers can improve testability of printed circuit assemblies by working together in the early stages of design.

 

3.0 OVERVIEW OF IN-CIRCUIT TEST SYSTEM

The basic idea of In-Circuit Testing relies upon the ability of the test system to test for opens, shorts, and component faults by electrically isolating components after they are mounted on the board. The components can be any combination of analog or digital parts, and Through-Hole or SMT devices.
