Abstract
An energy collector is used to assist a laser coupling process by reducing the amount of output power of a laser that is used to modify a device attaching element. The energy collector includes an energy collector tip configured to be placed proximate to a device attaching element during the laser coupling process. The energy collector tip is configured to receive laser energy reflected from the device attaching element during the laser coupling process and is formed from a material that converts this reflected energy to heat. Sufficient thermal coupling is created between the energy collector and a surface to provide a conductive pathway for the energy, which has been converted to heat, between the energy collector and the device attaching element.
Claims6
A method for reducing the amount of power used by a laser for coupling a plurality of components, the method comprising the steps of:
- placing a device attaching element on a surface;
- placing an energy collector proximate to the device attaching element;
- converting light energy from a laser beam that is reflected from the device attaching element onto the energy collector into heat in the energy collector;
- and
- creating sufficient thermal coupling between the energy collector and the surface to provide a conductive pathway for the energy collected by the energy collector to flow to the surface and to the device attaching element;
- whereby the collected energy is used to assist in modifying the device attaching element.
