1. A method comprising:
providing discrete components adhered to a dicing tape;
transferring the discrete components from the dicing tape to a dynamic release tape to form a discrete component assembly, the dynamic release tape being a freestanding tape, the discrete component assembly including (a) a flexible support layer, and (b) a dynamic release structure disposed on the flexible support layer, the discrete components being adhesively adhered to the dynamic release structure, the dynamic release structure including an active layer, the dynamic release structure being configured to generate a gas responsive to irradiation by light, the gas inducing a mechanical response in the active layer; and
positioning the flexible support layer of the discrete component assembly directly on a support plate of a component transfer system.
