ULE Series

Isolated, High Density, Eighth-Brick

1.25–30 Amp, DC/DC Converters

For these reasons, MPS developed disposable heat shields using high tem-

perature plastic. The DC/DC is installed and reﬂowed with the shield in place.

After successful reﬂow and cooling, and before washing, the heat shield should

be removed.

Temperature Proﬁling

We wish to ramp the temperature up and down to successfully reﬂow the

solder without heat damage. Each reﬂow oven, humidity conditions, solder

paste type, oven feed rate, and the number of heat zones all require a different

proﬁle. Therefore you may have to experiment.

PIN 1

DIMPLE

Since these converters are constructed using high temperature solders,

there will be no heat problems on your host pcb using traditional solder with

63% lead and 37% tin with a melting point of +183°C. Device lead tempera-

ture must remain below 230°C for less than 75 seconds, assuming that the

heat shield is in place. MPS uses a 216°C melt lead-free tin/silver/copper alloy

to assemble these converters.

There are several lead-free solders suitable for your host pcb depending on

your SMT system and whatever local certiﬁcation and environmental regula-

tions you must observe. Contact MPS if you need speciﬁc advice.

Heat Shield

Careful thermocouple testing has shown that the interior of the DC/DC under

the heat shield is tens of degrees cooler than the outside ambient temperature

for typical reﬂow proﬁles. This protects internal components and limits the

amount of reﬂow where it is not desired. The heat shield also includes marking

for product identiﬁcation and a date/lot code.

2.875

(73.03)

On ULE models, the heat shield is attached to the converter using molded

plastic pins on the heat shield interior which insert into recessed dimples in

the pinframe. An extra molded pin on the heat shield at the pin 1 location (and

corresponding notch on the pcb) can only be installed one way properly on the

pinframe. If the shield accidentally comes loose, it may be reinstalled by align-

ing the pins and dimples.

1.032

(26.21)

To remove the shield from the converter, after successful mounting and cool-

ing, squeeze the heat shield ears inward toward the converter body and pull the

shield upwards. Discard or recycle the shield. If you are using a ﬂux wash cycle,

remove the heat shield before washing to avoid coming loose inside the washer.
