scope:

This document is intended to assist in selecting the test equipment, test parameters, test data and fixturing required to perform electrical test(s) on printed electronics on e-textiles.

Printed electronics on e-textiles are printed electronics on coated or treated textile substrates.

Coatings and treatments may be applied for printability of the textile substrate and/or for performance of the textile substrate or finished printed electronics e-textile (e.g., hydrophobic, water retardance, flame retardance, surface energy). Coatings or treatments may be applied using printing, lamination or other processes.

Purpose

Electrical testing verifies that the conductive networks on the printed electronics on e-textile are interconnected according to the design requirements. Electrical testing does not ensure that the printed electronics on e-textile can be assembled or that the printed electronics on e-textile meets all of the customer's requirements. Many physical characteristics of the conductors (e.g., dimensional accuracy, conductor geometry and registration, presence of holes) cannot be determined by electrical test. Other checks should be employed to confirm these characteristics.
