Abstract: A bridge clip can provide off center loading between a lid and a semiconductor package during curing of adhesive for attachment of the lid to the integrated circuit die. This may be done, in some embodiments, without requiring an inventory of different parts and a variety of different assembly techniques by providing a leaf spring on the bridge clip which may be adapted for off center loading. The leaf spring may have its apex or centroid displaced with respect to the length of the bridge clip, transversely thereto or some combination thereof as needed. Thus, in some embodiments, a different leaf spring is all that needs to be provided to implement off center loading.

Abstract: Methods and apparatus to improve flux spray atomization and/or splash control are described. In one embodiment, a flux nozzle includes a plurality of injection holes to deposit flux fluid through an exit hole of an air cap onto a substrate (such as a printed circuit board). The flux fluid may atomize prior to deposition onto the substrate as relatively smaller broken down flux droplets that may aid reduced spray splash. Other embodiments are also described.
