Thirty-Second-Brick Isolated DC/DC Converters
with 2:1 Wide Input Range
Vertical Wind Tunnel
Murata Power Solutions employs a computer controlled custom-
designed closed loop vertical wind tunnel, infrared video camera sys-
tem, and test instrumentation for accurate air?ow and heat dissipa-

Heating
The IR camera monitors the thermal performance of the Unit Under
Test (UUT) under static steady-state conditions. A special optical port
is used which is transparent to infrared wavelengths.
Both through-hole and surface mount converters are soldered
down to a 10" x 10" host carrier board for realistic heat absorption
and spreading. Both longitudinal and transverse air?ow studies are
possible by rotation of this carrier board since there are often signi?-

cant differences in the heat dissipation in the two air?ow directions.
The combination of adjustable air?ow, adjustable ambient heat, and
adjustable Input/Output currents and voltages mean that a very wide
range of measurement conditions can be studied.
The collimator reduces the amount of turbulence adjacent to the
UUT by minimizing air?ow turbulence. Such turbulence in?uences the
effective heat transfer characteristics and gives false readings. Excess
turbulence removes more heat from some surfaces and less heat
from others, possibly causing uneven overheating.
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 that power supplies

Through-hole Soldering Guidelines
Murata Power Solutions recommends the TH soldering speci?cations below when install-
ing these converters. These speci?cations vary depending on the solder type. Exceeding
these speci?cations may cause damage to the product. Your production environment may
differ; therefore please thoroughly review these guidelines with your process engineers.
Wave Solder Operations for through-hole mounted products (THMT)
For Sn/Ag/Cu based solders:
are tested in real-world conditions.
SMT Re?ow Soldering Guidelines
The surface-mount re?ow solder pro?le shown below is suitable for SAC305 type lead-
free solders. This graph should be used only as a guideline . Many other factors in?uence
the success of SMT re?ow soldering. Since your production environment may differ,
please thoroughly review these guidelines with your process engineers.
