Electronics Design

System Development

YDL works with the customer from the conceptual stage to develop a set of requirements that meet the client's needs. We then develop a system of design that meets that client's performance requirement, cost and quality goal.

During this effort we perform the following tasks:

1. Performance and cost requirements are defined
2. Appropriate technologies are identified and tradeoff studies are conducted
3. Candidate designs are analyzed
4. Overall design approach is selected, including software algorithms and packaging
5. Unit cost goal is established
6. A Preliminary Design Review is conducted and the proposed design is presented to the client for approval

Design and Development

During this phase, YDL performs the detailed design, including:

1. Electronic design such as RF and microwave circuitry, antennas, analog and digital signal processors, embedded controllers, Ethernet and Internet interfaces, power conservation techniques, and necessary software.
2. Mechanical design that incorporates such elements as sealing, drop, shock and vibration characteristics, and miniaturization.
3. Preliminary drawing package generation
4. A design Review to obtain the client's approval to proceed to the prototype phase  

Prototype Fabrication

Upon completing the detailed design, prototypes are built in-house:

1. Prototype hardware is constructed by modifying off-the-shelf enclosures or using rapid prototyping parts
2. Components are carefully selected
3. Printed circuit board are designed and fabricated

Test, Evaluation and Certification

A qualification test plan is formulated that will verify that the product design meets the client's requirements. Upon approval by the client, the testing is performed and a report is prepared. Any failures are analyzed and recommendations are made to correct the problem. If necessary, all or part of the testing is repeated after corrections to the design and implemented. Typing testing includes performance measurements; temperature, shock and vibration testing; and certification testing to obtain FCC, UL and/or CE.
