Today's automobiles are equipped with electronics
that manage safety, performance, security, communications and other
complex systems. The growth of GPS, Bluetooth ®, adaptive cruise
control and other RF applications have increased the likelihood
of unwanted emissions and immunity problems that can compromise
system performance. Moreover, corporate and worldwide standards
for component and vehicle level RF emissions and immunity are very
SILENT has years of experience assisting global manufacturers to
resolve noise in a wide variety of applications including engine
controllers, remote keyless entry, fuel cell, crank and ceramic
pressure sensors and power accessory multiplexers. We can assist
early in the design process or troubleshoot when manufacturing schedules
are at risk.
Computers and Computer
With PCBs becoming more dense, integrated circuits
combining digital, RF, and analog data acquisition, clock speeds
running at 1GHz and beyond, and product lifetimes as short as 6
months - it is no surprise that hardware engineers are increasingly
challenged with unwanted RF emissions, circuit-to-circuit interference,
and/or rogue frequencies from external sources. Lost time is lost
revenue and can threaten market share.
SILENT can help. Our depth of experience allows us to make optimum
cost/performance decisions to minimize over-design while maximizing
success in first pass hardware. We have worked with leading Fortune
500 enterprise and personal computer and computer peripheral manufacturers
including Apple, Stratus, Samsung, LSI Logic/Engenio and American
While we strongly recommend noise reduction consultation in the
design phase, we also provide outstanding on-site "fire fighting"
services to rapidly identify and solve the most elusive electrical
noise problems. We work very quickly to develop a solution that
is cost-effective and manufacturable.
Medical Devices and Instruments
Today's scientific and medical instruments are
being designed with more powerful processors that increase performance,
accommodate increasingly sophisticated applications and simplify
ease-of-use. To be competitive in today's global economy, these
features must be provided through low-cost design and manufacturing
techniques and processes. This combination of performance, feature
set, and price sensitivity has opened the door to potential emissions
and immunity issues, particularly in health and industrial environments
where wireless infrastructure is commonplace.
SILENT'S extensive knowledge of scientific instrumentation combined
with years of experience in EMI and RF design can solve the most
complex electrical noise problems. We have experience with low
and high voltage linear and switch mode power supplies, motion
control, analog and digital sensors, high resolution analog to
digital conversion, and complex inter and intra system cabling.
Our knowledge of scientific instruments includes laser and infrared-based
mass spectroscopy, combustion control systems, precision osmometers,
high speed vision inspection and control systems, dermatological
lasers and "smart building" environmental sensors and controls,
to name a few.
Equipment and Industrial Facilities
Industrial and manufacturing control systems
have rigorous up-time requirements that make even the most infrequent
electrical noise and self-interference problems a nightmare. And
the working environment for process control electronics demands
robust circuit immunity to ever-present threats from electrostatic
discharge (ESD), radiated RF fields, and conducted power disturbances.
SILENT has an impressive record of successfully analyzing and
deploying EMI design and retrofit solutions for a variety of industrial
products and application environments. We travel on-site to the
customer's facility to troubleshoot and resolve elusive noise
problems. Our systems experience includes:
Precision measurement equipment
Computer controlled tire retread manufacturing facility
Multi-chip integrated circuit module manufacturing facility
10,000 unit/hour plastic molding machine
Ruggedized telephone test equipment
Manufacturing test equipment for high precision automotive
Electronic combustion controls for industrial furnaces
Connector and EMC
Design engineers are concerned with performance,
quality and cost when selecting EMC components for new system
design. Understanding design goals and manufacturing parameters
can be very helpful in developing customer relationships that
lead to repeat business.
SILENT provides insight into the design process and explains how
connector and component suppliers can customize their sales presentations
to align with engineering goals and compliance guidelines. Our
technical seminars yield invaluable ideas for new product and
service offerings, foster communications and show suppliers how
to strengthen ties with the customer base. Some of the topics
include technical translation of customer EMC requirements into
cost-effective and manufacturable prototypes and how to set up
a technical hotline for customer support.
Network and Telecom
SILENT has outstanding credentials in this sector.
We have worked with Cisco, Lucent, Avaya, Sycamore Networks, Samsung,
3Com and many other leaders in the networking and telecom industry.
Our experience ranges from terabit "metro-edge" optical routers
to low-cost unshielded Class B wireless access points - including
backplane design, internal power distribution, power over Ethernet,
mechanical design, and virtually every copper and optical input/output
EMI design challenge.
Our services accelerate time-to-market projects through proactive
schematic and PCB design reviews. We have also assisted new ventures
with last-minute hardware retrofit of flagship products to meet
market-sensitive manufacturing deadlines.
