 The EVN-12 is used for testing components in a JEDEC standardized still-air ambient environment. Thermal resistance measurements under natural convection conditions can be sensitive to uncontrolled air currents in a lab. The EVN-12 eliminates this potential source of testing error. Electrical connections are provided for all channel sense and heating power connections for direct connections to the Thermal Analyzers. The dual latch, dual hinge door ensures an air tight seal with a soft rubber gasket. The high quality 1/4" thick plastic cabinet is fabricated of transparent, non-yellowing, scratch-resistant plastic. The chamber includes a fixed JEDEC-compatible thermocouple probe for measuring the internal air temperature.
An optional infrared probe and adjustable support is available for measurement of IC case temperatures. These probes are factory calibrated by Analysis Tech for operation from 20 ° C to 120 ° C with an accuracy of ± 1.5° C for non reflective surfaces with a radiation emissivity of 0.8 - 1.0. This makes them ideal for plastic and ceramic surfaces. The view angle of these probes is such that the spot diameter is equal to half of the distance from the probe tip to the surface; thus the typical minimum spot diameter is 0.05 inch for a 0.100 inch spacing. The Analysis Tech infrared probes are plug compatible with the Thermal Analyzers and provide exceptional convenience for measurement of IC case temperatures.
