Surface Mount Information
Pick and Place
The Austin MicroLynx
TM 12V SMT modules use an
open 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 placing. The label meets all the
requirements for surface mount processing, as well as
safety standards and is able to withstand maximum
reflow temperature. The label also carries product
information such as product code, serial number and
location of manufacture.
Figure 33. Pick and Place Location.
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 pick &
placement speed should be considered to optimize
this process. The minimum recommended nozzle
diameter for reliable operation is 3mm. The maximum
nozzle outer diameter, which will safely fit within the
allowable component spacing, is 8 mm max.
Tin Lead Soldering
The Austin MicroLynx
TM 12V SMT power modules are
lead free modules and can be soldered either in a
lead-free solder process or in a conventional Tin/Lead
(Sn/Pb) process. 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.
In a conventional Tin/Lead (Sn/Pb) solder process
peak reflow temperatures are limited to less than
235
oC. Typically, the eutectic solder melts at 183oC,
wets the 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 CP
connector temperatures.
