A chip scale package or chip-scale package (CSP) is a type of integrated circuit package.

Originally, CSP was the acronym for chip-size packaging. Since only a few packages are chip size, the meaning of the acronym was adapted to chip-scale packaging. According to IPC's standard J-STD-012, Implementation of Flip Chip and Chip Scale Technology, in order to qualify as chip scale, the package must have an area no greater than 1.2 times that of the die and it must be a single-die, direct surface mountable package. Another criterion that is often applied to qualify these packages as CSPs is their ball pitch should be no more than 1 mm.

The concept was first proposed by Junichi Kasai of Fujitsu and Gen Murakami of Hitachi Cable in 1993. The first concept demonstration however came from Mitsubishi Electric.

The die may be mounted on an interposer upon which pads or balls are formed, like with flip chip ball grid array (BGA) packaging, or the pads may be etched or printed directly onto the silicon wafer, resulting in a package very close to the size of the silicon die: such a package is called a wafer-level package (WLP) or a wafer-level chip-scale package (WL-CSP). WL-CSP had been in development since 1990s, and several companies begun volume production in early 2000, such as Advanced Semiconductor Engineering (ASE).

Motor drive, or simply known as drive, describes equipment used to control the speed of machinery. Many industrial processes such as assembly lines must operate at different speeds for different products. Where process conditions demand adjustment of flow from a pump or fan, varying the speed of the drive may save energy compared with other techniques for flow control.

Where speeds may be selected from several different pre-set ranges, usually the drive is said to be adjustable speed. If the output speed can be changed without steps over a range, the drive is usually referred to as variable speed.

Adjustable and variable speed drives may be purely mechanical (termed variators), electromechanical, hydraulic, or electronic.
