Abstract

An approach for assembling and repairing probe assemblies using laser welding includes aligning a beam element to a post element on a probe substrate. The beam element is positioned in contact with the post element on the probe substrate. The beam element is then attached to the post element on the probe substrate by laser welding the beam element to the post element on the probe substrate. The approach may include the use of a vacuum capillary pickup tool to align and position the beam element. The vacuum capillary pickup tool may also operate in conjunction with a laser beam delivery system for guiding the laser beam to the correct location for welding and also to assist in removing gases and debris attributable to the laser welding process. The approach allows probe elements to be connected directly to a probe substrate without requiring an intermediate layer.
