Surface Mount Information

frame construction and are designed for a fully
automated assembly process. The modules are fitted
with a label designed to provide a large surface area
for pick and place operations. The label meets all the
requirements for surface mount processing, as well as
safety standards, and is able to withstand reflow
temperatures of up to 300
product information such as product code, serial
number and the location of manufacture.

Nozzle Recommendations
The module weight has been kept to a minimum by
using open frame construction. Even so, these
modules have a relatively large mass when compared
to conventional SMT components. Variables such as
nozzle size, tip style, vacuum pressure and placement
speed should be considered to optimize this process.
The minimum recommended nozzle diameter for
reliable operation is 6mm. The maximum nozzle outer
diameter, which will safely fit within the allowable
component spacing, is 9 mm.
Oblong or oval nozzles up to 11 x 9 mm may also be
used within the space available.

Reflow Soldering Information
The Austin MicroLynx
large mass, low thermal resistance devices and
typically heat up slower than other SMT components.
It is recommended that the customer review data
sheets in order to customize the solder reflow profile
for each application board assembly. The following
instructions must be observed when soldering these
units. Failure to observe these instructions may result
in the failure of or cause damage to the modules, and
can adversely affect long-term reliability.
Typically, the eutectic solder melts at 183
land, and subsequently wicks the device connection.
Sufficient time must be allowed to fuse the plating on
the connection to ensure a reliable solder joint. There
are several types of SMT reflow technologies
currently used in the industry. These surface mount
power modules can be reliably soldered using natural
forced convection, IR (radiant infrared), or a
combination of convection/IR. For reliable soldering
the solder reflow profile should be established by
accurately measuring the modules pin temperatures.
