alternatively known as the mainboard, system board, planar board or logic board or colloquially, a mobo) is the main printed circuit board (PCB) found in computers and other expandable systems. It holds many of the crucial electronic components of the system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Motherboard specifically refers to a PCB with expansion capability and as the name suggests, this board is the "mother" of all components attached

Chipsets A chipset is a set of electronic components in an integrated circuit that manages the data flow between the processor, memory and peripherals. It is usually found in the motherboard of a computer. Chipsets are usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance. The chipset normally consists of two major microchips. These

contemplating a change in their sourcing strategy for printed circuit boards (PCBs), which are used in many of their instruments. Recently, Stryker's suppliers of PCBs have become less reliable. They want to eliminate this problem by building a PCB production facility and produce the boards in house. In other words, they want to in-source the production of PCBs. This would give the company a great control over the quality of their boards. This proposal will require a total capital outlay of
