Design
We can develop your product from concept to manufacturing. We
will build prototypes to demonstrate performance and Compliance
per your electrical specifications. A design verification report
will be submitted upon project completion including Thermal,
Spice, Stress, MTBF and Worse Case Analysis.
Technical
Advising
We can assist your Engineering Staff in the development or
completion of current designs. Services we provide include:
Design Concept Feasibility, Thermal Analysis, Electrical
Specification Generation, Spice Analysis, Loop Stability
Analysis, Project Cost Analysis, Mean Time Between Failures (MTBF),
Safety Analysis.
Power Supply Troubleshooting
We will identify the trouble area
and provide the lowest cost implementation
solution in order to minimize production impact.
EMI/RFI
EMI/RFI filter design to be
compliant with European and American Standards (UL1950, CSA, EN
60950, etc.).
Noise Reduction Techniques
Shielding, Grounding, Filtering, Layout.
Printed
Circuit Board Design
Board layout is very critical in high frequency design. A poor
board layout
can upset circuit performance and cause EMI/RFI problems.
Our experienced PCB designers and
electrical designers utilize CAD analysis
techniques to achieve low noise levels.
Standard
and Planar Magnetics Design
We design high frequency
switchmode transformers, inductors, chokes, gate drive
transformers, Current sense transformers, Pulse transformers,
etc., utilizing standard and planar techniques. Power range from
5 watts to 5 kilowatts.
Planar
Magnetics allows Power Electronics designers to achieve low
profile
architecture that can be easily mounted on a printed
circuit board. Some of the benefits are:
-
High Power Densities
-
High Efficiency at high
operating frequencies, 97% typical.
-
Excellent high voltage
Isolation
-
Low parasitic reactances
-
Light Weight
-
Manufacturing repeatability
-
Low Profile
Miniature Power
Products for Robotics Applications
Dialex Engineering provides
miniature power solutions including dc-dc converters, general
purpose motion controls, smart drive servo amplifiers, servo
motors, smart battery chargers, and a host of software to offer
customers single-source control solutions for cost effective
applications ranging from one to thirty two axes of control.
Design and
Manufacturing of Standard and Automatic Test
Equipment.
Automated
test equipment (ATE) is computer controlled test and measurement
equipment, arranged in such a way as to be able to test a unit
with minimal human interaction. The advantage of this kind of
test is that they are repeatable and cost efficient in high
volume. Standard Test Equipment requires a higher level of human
interaction increasing Test time and a higher possibility of
measurement error.
Configurations for automated test
equipment include bed-of-nails (BON), flying probe, and optical.
In a bed-of-nails configuration each circuit net on the board is
connected to the tester, typically with one nail per net. The
ATE pin drivers send test signals through the probes which then
get routed to the PCB components via test land pads. BONs
typically require a vacuum or air source. The flying probe
system uses a low number of moving probes rather than the high
number of fixed probes in the BON. Test times may be slower due
to probe movements, but the method has compensating benefits. In
practice, a flying probe can provide
close to 100% test coverage on a
board with thousands of nets of passive components and
hundreds of
digital
devices. Optical inspection
methods include scanning probe
microscopes to reveal cold solder junctions, reverse polarity
components, wrong value devices, mis-aligned or missing
components, etc. Optical inspections do not need test fixtures
and require no electrical sources or measurements.
Our Design Team has many years of
experience with hardware selection and compatibility as well as
software programming languages such as Visual Basic, VB.net,
C/C++, Labview, and database development software such as Excel
and SQL.
