A Chip Scale Package (CSP) is a type of electronic packaging that allows a semiconductor chip to be housed in a compact form. It is designed to be nearly the same size as the chip itself, which helps save space on circuit boards. CSPs are commonly used in various devices, including smartphones and tablets, where minimizing size is crucial. CSP technology enhances performance by reducing the distance between the chip and the circuit board, leading to better electrical efficiency. This packaging method also improves thermal management, helping to dissipate heat more effectively. Overall, CSPs are essential for modern electronics, enabling smaller and more powerful devices.
