Patent ID: 8071907

Claim:
A method for assembling a sensor package, comprising: providing a sensor and a pair of dissimilar material parts to be welded together, wherein the sensor is fixed relative to at least one of the pair of dissimilar material parts; positioning said pair of dissimilar material parts in close proximity one to the other, thereby forming a weld line; and cleaning the surfaces of said pair of dissimilar material parts in the immediate vicinity of said weld line in order to remove surface contamination prior to the fusion of said pair of dissimilar material parts; clamping said pair of dissimilar material parts in order to assure good alignment and to eliminate relative motion at said weld line during welding; directing a high energy density beam to said weld line thereby creating a weld in order to join said pair of dissimilar material parts; and wherein during said directing step, a temperature of said weld is maintained below a vaporization temperature of each of said pair of dissimilar material parts.
