Abstract
A method includes positioning a discrete component assembly on a support fixture of a component transfer system, the discrete component assembly including a dynamic release tape including a flexible support layer, and a dynamic release structure disposed on the flexible support layer, and a discrete component adhered to the dynamic release tape. The method includes irradiating the dynamic release structure to release the discrete component from the dynamic release tape.
Claims19
A method comprising:
- positioning a discrete component assembly on a discrete component support fixture of a discrete component transfer system, the discrete component transfer system including
- a light source;
- the discrete component support fixture including (a) a support frame, and (b) a support plate positioned on the support frame, the support plate being transparent to light emitted by the light source;
- and
- an optical element disposed between the light source and the support frame,
- the discrete component assembly including (a) a dynamic release tape including a flexible support layer and a dynamic release structure disposed on the flexible support layer, and (b) a discrete component adhered to the dynamic release tape,
- wherein a top surface of the support plate is misaligned from a top surface of the support frame by an amount sufficient to introduce a tensile stress in the dynamic release tape held on the discrete component support fixture;
- and
- irradiating the dynamic release structure to release the discrete component from the dynamic release tape.

A discrete component transfer system comprising:
- a light source;
- a discrete component support fixture including (a) a support frame, and (b) a support plate positioned on the support frame, the support plate being transparent to light emitted by the light source, in which a top surface of the support plate is misaligned from a top surface of the support frame by an amount sufficient to introduce a tensile stress in a dynamic release tape held on the discrete component support fixture;
- and
- an optical element disposed between the light source and the support frame.

- a discrete component support fixture including (a) a support frame, and (b) a support plate positioned on the support frame, the support plate being transparent to light emitted by the light source;
- a discrete component assembly disposed on the discrete component support fixture, the discrete component assembly including (a) a dynamic release tape including a flexible support layer and a dynamic release structure disposed on the flexible support layer, and (b) a discrete component adhered to the dynamic release tape, in which the dynamic release structure is configured such that the discrete component is released from the dynamic release tape responsive to irradiation of the dynamic release structure by the light source;
- and
- an optical element disposed between the light source and the support frame,
- wherein a top surface of the support plate is misaligned from a top surface of the support frame by an amount sufficient to introduce a tensile stress in the dynamic release tape held on the discrete component support fixture.
