Method for a socket for the placement of critical RF components next to a BGA RF component

Disclosed is a method for a socket for the placement of critical radio frequency (RF) components next to a ball grid array (BGA) RF component. Benefits include improved functionality and an improved test environment.

Description

         The disclosed method enables critical RF components to be placed within 10 mils of the RF silicon under test. The critical components include devices such as:

•         Baluns

•         Variable crystal oscillators

•         RF amplifiers

•         Low noise amplifiers

•         Tuning components

         The disclosed method provides more accurate test data during the validation cycle of an RF silicon device than is conventionally available. Because key components are placed next to the device, silicon validation can be performed more quickly over several units with results that can be closely tied to software simulations performed during the design stage.

         The method prevents performance issues that otherwise occur because typical BGA socket sizes prevent devices from being placed within 2 inches of the silicon. Special low-inductance pogo pins minimize the impact of the springs when testing a device between 5 and 6 GHz.

Advantages

         The disclosed method provides advantages, including:

•         Improved functionality due to enabling the placement of RF components next to a BGA RF component

•         Improved test environment due to the capability to perform silicon validation more quickly over several units wit...
