Austin Lite Non-Isolated SMT DC - DC Power Modules:
Recommendation for Power Module Pick and Place
Placement of the Austin Lite can be achieved by choosing one of the below points.
Recommended Location
s
Pick Point 1: The Product ID label, which is attaced over the surface mount inductors, provides the largest and
most versatile pick point. This label is 0.340” x 0.440”. Up to an 8-mm outside diameter nozzle can be utilized to
obtain maximum vacuum pick-up. Smaller diameter nozzles can also be utilized. For all nozzle sizes, travel and
rotation speeds may need to be reduced. this off center pick point may pose some challenges for some vision
recognition systems.
Alternate Locations
s
Pick Points 2 and 3:
These points provide a location that is closest to the center of gravity on the x-axis center-
line. A nozzle size of 2.5mm to 3.7mm can be utilized in these locations. Care is needed to avoid nozzle contact
with adjacent components. Placement system accuracy needs to be verified. Travel and rotations speeds will
need to be reduced. It is possible that a custom nozzle can be designed to utilize both of these points simulta-
neously.
s
Pick Point 4: This point is only available to machines that can move off of the x-axis centerline. It provides a
larger surface area and is close to the center of gravity. A 4-mm outside diameter nozzle can be utilized. Travel
and rotations speeds will need to be reduced.
If rotational slipping occurs, rubber tipped nozzles can be utilized to prevent slippage.
These recommendations are general and apply only to machines that use vacuum nozzles to place components.
Machines with the capability of adding mechanical gripping to the sides of assembly can also be utilized.
Testing with a specific placement machine is recommended to determine optimal placement procedures.
