The CXA package is designed to enable ease-of-design and assembly. It has an easy to handle package. The larger solder pads make it easy to hand solder to the package. There is a large buffer between the optic and the solder pads, which provides more room to mount the optics. The solder pad buffer from the edges of the package is designed to make regulatory and safety approval easier. The optical source size is compliant with Zhaga defined sizes.
