Samsung patents laser method for moving LED chips

Samsung has filed a patent for a machine that uses lasers to detach light-emitting diodes (LEDs) from a large sheet. The device clamps the sheet between two supports and fires a laser through a clear barrier to cut or release specific sections.

Why it mattersThis filing describes a specific manufacturing technique for producing LED components, which are essential parts for screens and lighting.

In the filing’s own words

A method includes placing a work piece in an apparatus containing first support structure and a second support structure such that the work piece is located between the first support structure and the second support structure, generating a pressure on a portion of the work piece by actuating a movable member that presses on the work piece from a first side of the work piece to generate a first force on a first side of the work piece that presses a second side of the work piece against an optically transparent mechanical stop, and directing laser radiation through the optically transparent mechanical stop to irradiate the portion of the work piece.

What exactly they claim (claim 1)

1. An apparatus, comprising: a rigid structure comprising a first structural member supported above a second structural member thereby forming an open channel; an optically transparent mechanical stop supported by the first structural member; at least one laser radiation source positioned to provide laser radiation through the optically transparent mechanical stop; and a movable member supported by the second structural member, wherein the rigid structure is configured to receive a work piece in the open channel and to clamp the work piece by generating a pressure on the movable member such that the movable member presses on the work piece from a first side of the work piece to generate a first force on the first side of the work piece that presses a second side of the work piece against the optically transparent mechanical stop.
