ABSTRACT:
An electronic package having a controlled standoff height between a surface mount device and a circuit board. The electronic package includes a circuit board having a substrate and circuitry including mounting pads and a surface mount device having circuitry and contact terminals. Solder joints connect the contact terminals of the surface mount device to the mounting pads on the circuit board. A dielectric underfill is disposed between the circuit board and the surface mount device, and a plurality of standoff members are disposed in the underfill material to provide a separation distance between the circuit board and the surface mount device.
