Chip Scale Packaging (CSP)
CSP provides the smallest possible packaging solution for today's mobile products while preserving critical signal integrity.
California
Micro Devices is now shipping a number of its products in Chip Scale
Packages (CSP), providing hardware designers with a clean, low inductance
packaging solution for high speed applications. Chip Scale Packaging
enables CMD devices to utilize a 'flow through' design, allowing
optimal signal routing for critical board designs.
As an example, portable applications frequently demand EMI/RFI filtering
of signals in the 800 to 2,700 MHz band. CMD's unique thin film filters
provide a minimum of -30dB of attenuation over this frequency band.
The bump size and pitch of these filters are selected such that these
devices can be placed directly on a FR4 printed circuit board using
conventional assembly techniques. Ground-bounce and cross-talk are
minimized by a die design that results in a very 
low-impedance
contact to the common supply connection.
