Planning

Planning | |
---|---|
Requirements Planning | You know the market. We know design. You give us the feature set, target cost, and timing. We give you feedback, candor, and results. |
Conceptual Brainstorming | Tap into our broad experience for custom design approaches and new ideas. We offer a fast introduction to the market with a capable product. |
Specification Development | Specifications are broadly defined in the beginning and detail is added just in time. This preserves flexibility throughout the design process. |
Phased Scheduling | The highest value features are created first. You decide when sufficient features exist to make a viable product that can be upgraded later. |
Ongoing Communication | We will communicate throughout the process to prioritize features, create details, and track schedule performance. |
Hardware

Hardware | |
---|---|
Digital and Analog Design | Our electrical engineers have proven experience with a large variety of components and circuits. |
Schematic Capture | We use PADS to allow collaboration with other designers. We have streamlined procedures to export to manufacturing. |
PCB Layout | Our designs maximize performance and minimize defects. Our in-house production feedback loop creates continuous improvement. |
Wire Harness | We design and produce wire harnesses with specialties in laser etched connector marking, braided loom, overmolding, and testing. |
Enclosure Design | With 3D design tools, we can create custom molded plastic or we can CNC rout standard enclosures. |
Focus on Cost | You will benefit from our knowledge of volume component costs, process times, and assembly methods. |
Software

Software | |
---|---|
Agile Development Process | Our programming team works together to specify, code, test, and document entire features before moving on to lower priority features. This ensures that you get a functional, tested product, with must-have features quickly. |
Embedded C Microcontroller Software | We have written code for 8, 16, and 32 bit projects for Atmel, TI, Motorola, and Microchip. We specialize in Microchip design due to cost and availability. |
Communication Protocols: CAN, USB, WIFI, etc. | Interconnections are extremely important when focusing on modular designs. We have significant experience with protocol design. |
Field Updateable Boot-loaders | We have written update mechanisms from USB, SD card, serial, CAN, WIFI, SPI, and I2C. |
Supporting PC Applications | We often create PC applications to interface with the product being designed. They range from simulation software to software update tools to automated test applications. |
Validation

Validation | |
---|---|
Quick Turn Electronic Prototypes | Quantity range: 1 to more than 100. Lead time: 1 – 3 weeks – the entire process includes bare board production, surface mount assembly, and through-hole soldering. |
Verification and Validation | Testing plans are created and executed throughout the design process as features are created. Tests are automated to simulate a wide variety of conditions. Results are documented and used to improve the design before release. |
Agency Approvals | We interface with test labs when seeking UL, CE, FCC, and other agency approvals. |
FMEA and DFM Reviews | Our knowledgeable manufacturing engineers and production supervisors review new designs for potential defects and costly labor steps. |
Beta / Pilot Production | We can move easily from prototypes into production with in-house circuit board and wire harness capabilities. |
Manufacturing Test Design | We love to share our experience developing automated testers. A good manufacturing test will be independent of operator judgement, exercise all circuits, and report specific defects. |
Production

Production | |
---|---|
Surface Mount Assembly | Our systems control production bills of materials (BOMs), verify reel setup, and automatically inspect each component (AOI) |
Through-Hole and Robotic Soldering | Surface mount components are used wherever possible. Most other components are compatible with our robotic soldering equipment. Hand soldering is used for direct wire and cable attachment. |
Wire Harness Fabrication | We have automatic wire processing lines that measure quality on every crimp. Each harness is tested for continuity, shorts, and inline component polarity. |
Final Assembly and Testing | Whether assembled into a plastic enclosure or potted into a box, every device is tested at least once. We have a custom defect tracking system to provide feedback for design and process improvements. |
Manufacturing Documentation | We are the connoisseurs of our own design documentation. Efforts are made to be complete, clear, and concise. |
Support

Support | |
---|---|
Design and Process Improvements | Most surface mount defects can be eliminated through correct copper pad and stencil aperture sizing. Products are routinely reviewed for opportunities to remove defects, assembly time, or component cost. |
Solutions for Unavailable Components | Every effort is made to create designs with components that will be available throughout the product life cycle. If parts become obsolete or scarce, we are prepared to find alternates or change the design to eliminate the bottleneck. |
Warranty | We offer warranty and refurbishment programs based on contract negotiations. |
Service and Repair | For products that are out of warranty, we offer cost effective solutions for service and repair. |
Field Failure Analysis | Data is collected on root cause of failures returned in or out of warranty. Lessons learned are incorporated in later revisions and new products. |
