We have a strong
engineering team, with a combined experience of over 5 years, covering
almost all areas of electronics engineering. Most of the building blocks
for common electronics applications are already there, ready to be
integrated into your project. That is one of the reasons why we can
deliver the prototypes or go into production much faster than other
providers. The following is a non-exhaustive list of our engineering and
manufacturing capabilities.
PCB Design and Optimization
We design single-sided or double-sided,
single-layer or multi-layer, through hole, SMT, COB printed circuit
boards. We can design from ground up or design according to your
specifications. Our experienced design engineers also optimize the design
for compactness, cost, yield, safety and EDS/EMC requirements. The PCBs
are fully tested for functions and reliability. Full documentation
including schematics and BOM are provided to the customer as a
complete package. The formats of the design files that we provide are
compatible with most commonly used CAD formats in the industry. Our board
design engineers works with other members in the team to guarantee that
all important aspects of production be considered, including low cost in
material, high efficiency in manufacturing and assembly, and high
performance in functionality.
Analog and Digital System Development
Our team is strong in both analog and
digital system design and their integration. We have experience working
with various sensors, such as temperature, humidity, pressure,
displacement, velocity, acceleration, vibration, etc. We have developed or
worked with various types of data acquisition systems, high speed systems,
and high precision and high accuracy systems (such as industrial test
equipment and calibrators). On the digital side, we can work with simple
digital logic circuits, programmable logic devices, digital signal
processors (DSPs), and microprocessors (microcontrollers). For large-scale
projects, when it is necessary, we can integrate a full PC mother board
into the system, to take advantage of the existing configuration and
resources.
Microprocessor-based Design with Embedded Software
Microprocessors greatly extend the
flexibility of the design and functions of digital systems, providing
high performance and convenient user interface for electronics products.
We design simple digital systems that only involves logic circuits, as
well as complicated digital systems that features real time processing,
multitasking and networking. Our engineers are experienced with various
types of microprocessors from different chip makers such as Rockchip,Atmel,Sunplus,
Microchip, Texas Instruments, Actions-semi, etc.
With the drastic reduction in the cost of commonly used
microprocessors over the years, now most project can afford a design
with microprocessors if necessary. The technology has also made it
possible for many models to work at very low current, a situation
required for hand-held devices working on batteries. We work with very
small microcontrollers to high-end CISPs and DSPs with integrated
peripherals, with full capacity of hardware design and software
development, all according to your specifications.
PC-based Hardware and Software Development
Some applications require that the hardware and software be
designed based on a regular computer. Our engineers are experienced in
designing systems and devices that work with a regular computer, through
parallel, serial, USB, firewire, Ethernet or any other types of
interfaces, under various types of operating systems including various
versions of Windows and Linux. For certain applications, we build around a
PC motherboard, taking advantage of the existing structure and resources.
In either case, our software engineers develop full functioning software
with friendly graphic user interface (GUI) for the system. One example is
a computer security system that uses a Linux system, which we designed for
a client for commercial institutions.
Wireless Control and Communications
We are experienced in the design involving wireless control
and wireless communications. Depending on the application, various
wireless transmission and reception approaches can be used, including
radio frequency (of varied frequencies), visible and invisible optical
link (including infrared), ultrasound, etc. It can be as simple as a
remote control such as that for your TV set or garage door, or as
complicated as a full scale networked data transmission and management
system. One example is the VoIP phone that we designed and manufactured
for a proprietary network.
Network-based Design
Our engineers have a strong background
in the design and development of systems that work over proprietary and
standard networks, in both industrial and commercial applications. We
have developed hardware and software for data deployment and management
systems, based on various types of protocols. Some of the systems work
in harsh industrial environments. We also designed and manufactured
devices that include embedded hardware and software, allowing them to
communicate through the Internet. One example is an interactive
advertising and messaging system that we designed and manufactured,
involving multiple display units that can be remotely managed through
the Internet by a central management station.
Audio, Visual and User Interactive
Products
Many consumer devices these days
involve certain type of audio and/or visual components. Most industrial
devices and equipment also involves these and other interactive
components. Our engineers are experienced in integrating all these
components seamlessly into your application, making it outstanding in
appearance, superior in function and friendly in user interaction.
The display that we work with includes LED, LCD
(monochrome and full color TFT), OLED, VFD, ELP, etc. We also design
touch panels (resistive, capacitive, sensor-based, etc.) and various
types of keypads (including backlit membrane keypads). One example is
the test and measurement equipment that we designed and manufactured,
involving monochrome and color LCDs and touch panels.
Design of
Enclosure
As an essential part of a complete
turn-key solution, we design and supply various types of enclosures
with our electronics products. The molding and injection are conducted in
a sub-contracted factory that associates closely with us on a long-term
basis. We are capable of making rugged enclosures for harsh industrial
applications, as well as cool-looking enclosures for consumer products.
Our electronics design engineers work side by side with the molding
designer, to guarantee that the enclosure fits the PCB, display and other
parts, and is appropriate in manufacturing and assembly. For certain
applications, we also recommend to the client cost effective,
off-the-shelf enclosures if the quantity and other factors justify it.
Re-design and Reverse Engineering
We have experience dealing with old or obsolete designs. We
can revise the design based on the old design; we can make a design based
on the functions of an old device; or we can simply start from scratch
based on a description of an obsolete device and improvements required by
the client. We can also replicate products or parts if they are otherwise
unavailable. One example is that we routinely re-design and re-tool LCD
display modules and other parts that other manufacturers have stopped
supporting, but are still needed by many of our clients for their existing
line of products. (These services are subject to

Diagnostic and
Remedial Solutions
What if you are so disappointed by the previous design
engineering firm or contract manufacturer whom you hired for developing
and making your products? Contact us for a diagnostic and/or remedial
solution! Believe it or not, many of our current clients came to us for
this very purpose. There are various reasons why a specific design does
not work. In most cases, it's only a simple twist of parameters on
the PCB or a revision of the embedded software. In any case, we can help
you if you feel not treated with full effort somewhere else.
