1. A multi-zone temperature testing system, comprising:
a test device having a plurality of components and including a first side and a second side that is located opposite the test device from the first side;
a first multi-zone temperature testing device that is coupled to the first side of the test device and that includes a first thermoelectric module that is located adjacent a first subset of the plurality of components and a second thermoelectric module that is located adjacent a second subset of the plurality of components;
a second multi-zone temperature testing device that is coupled to the second side of the test device and that includes a third thermoelectric module that is located adjacent the first subset of the plurality of components and a fourth thermoelectric module that is located adjacent a second subset of the plurality of components; and
a temperature control subsystem that is coupled to the first multi-zone temperature testing device and the second multi-zone temperature testing device and that is configured to:
control the first thermoelectric module in the first multi-zone temperature testing device to produce a first heat flux and control the third thermoelectric module in the second multi-zone temperature testing device to produce a third heat flux, wherein the first heat flux and the third heat flux provide a first testing temperature for the first subset of the plurality of components; and
control the second thermoelectric module in the first multi-zone temperature testing device to produce a second heat flux and control the fourth thermoelectric module in the second multi-zone temperature testing device to produce a fourth heat flux, wherein the second heat flux and the fourth heat flux provides a second testing temperature for the second subset of the plurality of components that is different than the first testing temperature.
