Electronics bending fixture design

A method for testing a flexible sample, comprising:

• securing a sample to a sample holder positioned on an outer surface of a mandrel;
• pressing the sample against the mandrel with a distal end of a retractable holder with a predetermined force;
• powering a motor that is operably connected to the mandrel to rotate the mandrel in a first direction from an initial mandrel angle to a final mandrel angle such that a distal end of the sample is positioned between the retractable holder and the mandrel, and the sample conforms to the outer surface of the mandrel;
• and
• powering the motor to rotate the mandrel in a second direction from the final mandrel angle to the initial mandrel angle such that a proximal end of the sample is positioned between the retractable holder and the mandrel, and the sample cantilevers from the sampler holder without conforming to the outer surface of the mandrel.

A testing system for a flexible sample, comprising:

• an upper member having:
• a first downwardly-descending arm having at least one mandrel that defines at least one slot;
• a second downwardly-descending arm having at least one mandrel that defines at least one slot;
• and
• a lower member having:
• an upwardly-ascending arm having a first mandrel and a second mandrel that define a central slot,
• wherein the upper member moves relative to the lower member such that a portion of a sample, positioned in the at least one slot of the first downwardly-descending arm, the at least one slot of the second downwardly-descending arm, and the central slot, conforms to one of the first and second mandrels of the upwardly-ascending arm.
