End Point Electrical Tests
MPS has invested in a Qualmark OVS-1 HALT tester capable of applying
voltage and temperature extremes as well as 6-axis, linear and rotational,
random vibration. A typical HALT profile (shown above) consists of thermal
cycling (–55 to +125°C, 30°C/minute) and simultaneous, gradually increas-
ing, random longitudinal and rotational vibration up to 20G’s with load cycling
and applied-voltage extremes added as desired. Many devices in MPS’s new
A-Series could not be made to fail prior to reaching either the limits of the
HALT chamber or some previously known physical limit of the device. We
also use the HALT chamber and its ability to rapidly cool devices to verify
their "cold-start" capabilities.
Qualification
For each new product, electrical performance is verified via a comprehensive
characterization process and long-term reliability is confirmed via a rigorous
qualification procedure. The qual procedure includes such strenuous tests as
thermal shock and 500 hour life. Qual testing is summarized below.
* Interim electrical test at 200 hours.

In-Line Process Controls and Screening
A combination of statistical sampling and 100% inspection techniques keeps
our assembly line under constant control. Parameters such as solder-paste
thickness, component placement, cleanliness, etc. are statistically sampled,
charted and fine tuned as necessary. Visual inspections are performed by
trained operators after pick-and-place, soldering and cleaning operations.
Units are 100% electrically tested prior to potting. All devices are temperature
cycled, burned-in, hi-pot tested and final-electrical tested prior to external
visual examination, packing and shipping.
Rapid Response to Problems
MPS employs an outstanding corrective-action system to immediately
address any detected shortcomings in either products or processes. When-
ever our assembly, quality or engineering personnel spot a product/process
problem, or if a product is returned with a potential defect, we immediately
perform a detailed failure analysis and, if necessary, undertake corrective
actions. Over time, this system has helped refine our assembly operation to
yield one of the lowest product defect rates in the industry.

Soldering Guidelines
Murata Power Solutions recommends the specifications below when
installing these converters. These specifications vary depending on the
solder type. Exceeding these specifications may cause damage to the
product. Be cautious when there is high atmospheric humidity. We strongly
recommend a mild pre-bake (100° C. for 30 minutes). Your production en-
vironment may differ; therefore please thoroughly review these guidelines
with your process engineers.
