System In Package (SiP)

Description. A system in package, or SiP, is a way of bundling two or more ICs inside a single package. This is in contrast to a system on chip, or SoC, where the functions on those chips are integrated onto the same die. SiP has been around since the 1980s in the form of multi-chip modules. Rather than put chips on a printed circuit board ...
