Planning

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

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

Software
Agile Development ProcessOur 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 SoftwareWe 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-loadersWe have written update mechanisms from USB, SD card, serial, CAN, WIFI, SPI, and I2C.
Supporting PC ApplicationsWe 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
Engineering Controls Validation

Validation
Quick Turn Electronic PrototypesQuantity 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 ValidationTesting 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 ApprovalsWe interface with test labs when seeking UL, CE, FCC, and other agency approvals.
FMEA and DFM ReviewsOur knowledgeable manufacturing engineers and production supervisors review new designs for potential defects and costly labor steps.
Beta / Pilot ProductionWe can move easily from prototypes into production with in-house circuit board and wire harness capabilities.
Manufacturing Test DesignWe 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
Engineering Controls Production

Production
Surface Mount AssemblyOur systems control production bills of materials (BOMs), verify reel setup, and automatically inspect each component (AOI)
Through-Hole and Robotic SolderingSurface 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 FabricationWe 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 TestingWhether 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 DocumentationWe are the connoisseurs of our own design documentation. Efforts are made to be complete, clear, and concise.
Support

Design and Process ImprovementsMost 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 ComponentsEvery 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.
WarrantyWe offer warranty and refurbishment programs based on contract negotiations.
Service and RepairFor products that are out of warranty, we offer cost effective solutions for service and repair.
Field Failure AnalysisData is collected on root cause of failures returned in or out of warranty. Lessons learned are incorporated in later revisions and new products.
