Jig apparatus and fastening method using the same

A fastening method, comprising:

• preparing a laminate by loading a plurality of trays in which light emitting devices are received;
• preparing a first jig apparatus including a body having a bent structure by bending a central portion of the body so as to protrude toward a first surface of the body, and first and second extending portions respectively bent and extending from a first end and a second end of the body in a length direction thereof;
• allowing the first and second extending portions to be engaged with and fixed to protrusions respectively provided on edges of one ends of an upper tray and a lower tray among the plurality of trays loaded in the laminate, while pre-fastening the first jig apparatus to one end of the laminate such that a protruding surface of the body is outwardly disposed;
• pre-fastening a second jig apparatus to an other end of the laminate, opposing to the one end of the laminate;
• and
• fastening the first jig apparatus to the laminate by applying pressure to a center of the first surface of the body in such a manner the protruding central portion of the body protrudes toward a second surface of the body.

A jig apparatus fastening loaded trays having light emitting devices received therein, the jig apparatus comprising:

• a body having a first surface and a second surface opposing the first surface;
• and
• extending portions extending from the first surface of the body in an extending direction, wherein
• the body has a bent structure with respect to a central portion of the body such that when both ends of the body are fastened, the central portion moves from a position protruding toward the second surface of the body in a direction opposite to the extending direction, to a position protruding toward the first surface in the extending direction.
