An image sensor includes filters formed over a portion of an array of photosensitive elements in a predetermined pattern. The pattern can be such that the exposure of a matrix (such as a 2-by-2 square of pixels) to light (such as blue light) is improved, while maintaining acceptable capability to capture light across the entire spectrum. The pattern can be such that two blue filters, one red, and one green filter is used by a 2-by-2 square matrix of pixels. The pattern can also include cyan, yellow, and magenta (CYM) filters.

Image sensor having differing wavelength filters

A reflowable camera module has a set of solder joints formed on a bottom surface of the camera module that provide electrical signal and power connections between the camera module and a printed circuit substrate. The solder joints are susceptible to failure caused by shear forces, particularly in corner regions. Additional localized mechanical supports are provided to protect those solder joints carrying power and electrical signals for the camera module. The localized mechanical supports are formed outside of a region containing the solder joints carrying power and electrical signals. The localized mechanical supports may include dummy solder joints formed in corner regions and/or dummy leads used to support the camera module. Solder joint reliability is enhanced without requiring the use of an underfill encapsulant.
