Scope
This specification is meant to be broad enough to incorporate a wide variety of surface mount area array
package (e.g., BGA) design features and technologies. However, due to a limited number of signal layers
that results in shorting some device pins in this specification, the boards described here may not be
adequate for measurement of active devices as compared to applications with thermal test chips.
