Pressure assisted self targeting assembly

摘要

The invention relates to a component (10) placement method for placement of a component (10) on a flexible substrate (20), comprising: providing a flexible substrate (20); administering a component (10) to a support face, the support face comprised of by the flexible substrate or by a support structure to be aligned with the flexible substrate; generating an air flow in an out of plane orientation relative to the support face; and directing the component (10) to a placement position (30) by means of a directional structure provided on the support face; wherein the component (10) is levitated from the support face (20, 70) by said air flow or by vibrational contact between the support face and the component induced by said air flow; and wherein, when the support face is comprised by a support structure distinct from the flexible substrate, the support face is aligned with the flexible substrate. Accordingly, air cushion or intermittent contact forces (modulated in time and space using modulated micro-features) can be used to provide local interactions with the micro-part so as to position micro-parts with reference to micro-features arranged on the flexible substrate.
