Compression system calibration

A system to aid in a calibration of a compression system comprising:

• a first substrate having a test film on a first surface;
• a second substrate having a plurality of spikes arranged in a spike pattern on a second surface;
• a press having a plurality of calibration parameters, the press is configured to:
• mount the first substrate with the first surface facing outward;
• mount the second substrate with the second surface of the second substrate facing the first surface of the first substrate;
• compress the first substrate and the second substrate together with a force that causes the plurality of spikes to form a plurality of indentations in the test film;
• and
• separate the first substrate from the second substrate;
• and
• a sensor configured to determine a plurality of local pressures applied by the plurality of spikes against the test film during the compression, wherein one or more of the plurality of calibration parameters of the press is configured to adjust in response to the plurality of local pressures and wherein each of the plurality of spikes is formed with an over-coat layer that prevents a formation of a metallurgical bond between the plurality of spikes and the test film during the compression.

A method to aid in a calibration of a compression system comprising:

• mounting a first substrate with a first surface facing outward in a press, wherein the press has a plurality of calibration parameters, and the first substrate has a test film on the first surface;
• mounting a second substrate in the press with a second surface of the second substrate facing the first surface of the first substrate, wherein the second substrate has a plurality of spikes arranged in a spike pattern on the second surface;
• compressing the first substrate and the second substrate together with a force that causes the plurality of spikes to form a plurality of indentations in the test film;
• separating the first substrate from the second substrate;
• determining, with a sensor, a plurality of local pressures applied by the plurality of spikes against the test film during the compressing;
• adjusting one or more of the plurality of calibration parameters of the press in response to the plurality of local pressures;
• and
• generating a pressure map in two-dimensions based on the plurality of local pressures, wherein the adjusting of the one or more of the plurality of calibration parameters of the press is in further response to the pressure map.
