Abstract
A system for laser welding microfluidic components including a first component having a boss disposed thereon, the boss raised a first distance off of the first component, wherein the boss has a chamfer circumscribing an edge of the boss, a second component having a recess disposed therein, the recess shaped to receive the boss, the recess having a first depth, wherein the first depth is less than the first distance, and a laser configured to emit a laser beam.
Claims22
A system for laser welding microfluidic components, comprising:
- a first component having a boss disposed thereon, the boss raised a first distance off of the first component, wherein the boss has a chamfer circumscribing an edge of the boss;
- a second component having a recess disposed therein, the recess shaped to receive the boss, the recess having a first depth, wherein the first depth is less than the first distance;
- and
- a laser configured to direct a laser beam to a weld surface formed where the boss contacts the recess.
1 more element
A method for laser welding microfluidic components, comprising:
- providing a microfluidic component having a recess;
- providing a component having a boss with a corresponding geometry to the recess;
- engaging the boss with the recess, thereby aligning the component with the microfluidic component at a weld surface;
- and
- providing a laser beam directed at the weld surface, thereby welding the component and the microfluidic component.
