IR Transparent The system includes a precision low fl ow-rate anemometer, optical window Variable variable speed fan, power supply input and load controls, Unit under speed fan temperature gauges, and adjustable heating element. test (UUT) The IR camera monitors the thermal performance of the IR Video Unit Under Test (UUT) under static steady-state conditions. A Camera special optical port is used which is transparent to infrared wavelengths. Both through-hole and surface mount converters are soldered down to a 10˝ X10˝ host carrier board for realistic heat absorption and spreading. Both longitudinal and trans- Heating verse airfl ow studies are possible by rotation of this carrier element board since there are often signifi cant differences in the heat Precision dissipation in the two airfl ow directions. The combination of low-rate adjustable airfl ow, adjustable ambient heat, and adjustable anemometer Input/Output currents and voltages mean that a very wide 3” below UUT range of measurement conditions can be studied. The collimator reduces the amount of turbulence adjacent Ambient to the UUT by minimizing airfl ow turbulence. Such turbu- temperature lence infl uences the effective heat transfer characteristics sensor and gives false readings. Excess turbulence removes more heat from some surfaces and less heat from others, possibly Airflow causing uneven overheating. collimator Both sides of the UUT are studied since there are different thermal gradients on each side. The adjustable heating element and fan, built-in temperature gauges, and no-contact IR camera mean Figure 6. Vertical Wind Tunnel that power supplies are tested in real-world conditions. Soldering Guidelines Murata Power Solutions recommends the specifi cations below when installing these converters. These specifi cations vary depending on the solder type. Exceeding these specifi ca- tions may cause damage to the product. Be cautious when there is high atmospheric humidity. We strongly recommend a mild pre-bake (100° C. for 30 minutes). Your production environment may differ; therefore please thoroughly review these guidelines with your process engineers.
