Abstract

A method of batch transferring micro components comprising steps of: A. arranging multiple probes in array on a carrying unit and extending multiple columns of the multiple probes out of a bottom of the carrying unit; B. providing a temperature control conduit in the carrying unit into which hot water is fed; C. driving the carrying unit so that the multiple columns of the multiple probes dip an adhesive material; D. feeding cold water into the temperature control conduit; E. moving the carrying unit on micro components and pressing the multiple probes of the carrying unit downward; F. moving the carrying unit onto a substrate and pressing the micro components to desired positions respectively; and G. heating adhesive material again as pressing the micro components and controlling the substrate at a low temperature so that the adhesive material freezes among the micro components and the substrate.

Claims (17)

1. A method of batch transferring micro components comprising steps of:

A. arranging multiple probes in array on a carrying unit, and extending multiple columns of the multiple probes out of a bottom of the carrying unit;

B. providing a temperature control conduit in the carrying unit into which hot water is fed so as to heat the multiple probes;

C. driving the carrying unit so that the multiple columns of the multiple probes dip an adhesive material;

D. feeding cold water into the temperature control conduit so as to drop temperature of the multiple probes, hence the adhesive material adheres on the multiple columns of the multiple probes;

E. moving the carrying unit on micro components and pressing the multiple probes of the carrying unit downward so that the adhesive material contacts the micro components;

F. moving the carrying unit onto a substrate and aligning and pressing the micro components to desired positions respectively; and

G. heating the adhesive material again as pressing the micro components so that the adhesive material melts and flows onto the substrate, and controlling the substrate at a low temperature so that the adhesive material freezes among the micro components and the substrate, thus batch transferring the micro components.

2. The method as claimed in claim 1 , wherein in the step B, the temperature control conduit is defined by a winding channel around the multiple probes, and an inlet segment and an outlet segment of the winding channel extend out of a top of the carrying unit, and the hot water flows through the winding channel so as to heat the multiple probes.

3. The method as claimed in claim 1 , wherein in the step D, the temperature control conduit includes a winding channel arranged around the multiple probes, an inlet segment and an outlet segment of the winding channel extend of a top of the carrying unit, and the temperature control conduit includes a control valve disposed on the inlet segment thereof so as to flow the cold water into the winding channel, thus reducing a temperature of the multiple probes.

4. The method as claimed in claim 1 , wherein in the step E, the micro components are moved and arranged onto a platform at a predetermined distance, hence after the adhesive material on the multiple columns contacts the micro components, the carrying unit lifts, and the micro components are removed upward from the platform.

5. The method as claimed in claim 1 , wherein in the step E, each probe has a first connection portion formed on a bottom thereof, and each of the micro components has at least one second connection portion formed on a top thereof so as to retain the first connection portion of each probe, hence each probe temporarily retains each micro component.

6. The method as claimed in claim 2 , wherein in the step B, a temperature of the hot water of the winding channel is within 50° C. to 140° C.

7. The method as claimed in claim 2 , wherein in the step D, a temperature of the cold water of the winding channel is within 0° C. to 30° C.

8. The method as claimed in claim 1 , wherein after the step A, leveling the multiple probes on the carrying unit so that the multiple columns of the multiple probes are flushed with one another.

9. The method as claimed in claim 1 , wherein in the step C, the adhesive material is any one of flux, glue, and underfill.

10. The method as claimed in claim 1 , wherein in the step E, a first connection portion of each probe and at least one second connection portion of each micro component are in any one of cone, polygon, circle, and arc shapes.
