Abstract
An example flexible substrate testing system includes: a first substrate support structure configured to hold stationary a first portion of a flexible substrate under test; a second substrate support structure configured to hold a second portion of the flexible substrate; an actuator configured to move the second substrate support structure to fold the flexible substrate and to unfold the flexible substrate; and a load cell configured to measure a load on the flexible substrate.

A flexible substrate testing system, comprising:
- a first substrate support structure configured to hold stationary a first portion of a flexible substrate under test;
- a second substrate support structure configured to hold a second portion of the flexible substrate;
- an actuator configured to move the second substrate support structure to fold the flexible substrate and to unfold the flexible substrate;
- a load cell configured to measure a load on the flexible substrate;
- and
- a flexure configured to hold the first substrate support structure and to limit motion for the first substrate support structure to a direction in which the load cell is configured to measure the load.
A method to measure loads on a flexible substrate, the method comprising:
- holding stationary, via a substrate support structure, a first portion of a flexible substrate under test;
- moving, via an actuator, a second portion of the flexible substrate to fold the flexible substrate or to unfold the flexible substrate;
- limiting motion, via a flexure, for the first portion of the substrate support structure in a direction parallel to the first portion of the substrate support structure;
- and
- measuring a load on the flexible substrate resulting from the moving.
A flexible substrate testing system, comprising:
- a first plate comprising a first surface configured to hold stationary a first side of a flexible substrate under test;
- a flexure configured to hold the first plate and to limit motion of the first plate in directions parallel to the first surface of the first plate;
- a second plate comprising a second surface configured to hold a second side of the flexible substrate;
- a first guide plate configured to guide a motion of the second surface to fold the flexible substrate and to unfold the flexible substrate;
- an actuator configured to move the second plate in accordance with the first guide plate to fold the flexible substrate and to unfold the flexible substrate;
- and
- a load cell configured to measure loads on the first plate while the actuator moves the second plate.
