MTC-thermal setup requirements

1. You will need a temperature forcing instrument such as ECO-810 from Intest.  (Imag 2). Allow extra space for a temperature forcing instrument in the lab.

2. MTC-Thermal and a temperature forcing instrument are connected via Swagelok fittings to simplify the connect and disconnect process. (Image 2)

3. You can use a T or K type thermal couple routed into the chamber from a temperature forcing instrument through penetration in the chamber that is then sealed with high temp silicone plugs. (Image 3)

4. The PCB-Thermal must be designed with MTC-Thermal use in mind (Additional charge applies) - additional backside purge plate, additional mounting facilities for the PT100, and no holes unplugged between the top and bottom side of the PCB. The standard CRES PCB does not have MTC-Thermal capability.

1. The latest MTC-Thermal has a larger, better-insulated chamber to allow condensation-free performance down to -55C.  

2. You need to order the MTC-thermal for either XT or LR as the insulated stiffener that provides a thermal break between the chamber and the tester is different.   

3. You can measure the temperature inside the chamber using a PT100 platinum resistor mounted on the PCB surface inside the chambered area. We measure this using MPT channels routed in the PCB and convert them to temperature.   

4. You can communicate directly with the temperature forcing instrument. Drivers for different models can be developed if they have an external communication layer.   

5. We have a single and dual stepper version so that you can choose 500lb or 1000lb force capabilities.  

6. We can cycle at hot or cold to test CRES using whatever MTC recipe you set. Using ECO-810 takes about 15 minutes to ramp to -40C. Because it has a relatively small envelope, it can ramp in a reasonable time depending on your temperature forcing unit capabilities and will hold that desired temperature within ~ 1/2 degree.    

7. Image 6 shows the latest single stepper version for MPT-XT. It docks on and off the tester by removing the top stiffeners, inserting the PCB and docking this on the top of the PCB, and locking it down with the same actuator mechanism used for the normal PCB top stiffeners on the tool. Therefore, there are no bolts to remove or tighten. It's a simple MPT docking as usual.
