What we can do for you

 Turn-key Product Development

• Deliver “paper designs” and/or analysis
• Deliver tested prototypes on PC boards
• Deliver a final manufacturable product with
documentation
PC board artwork
packaging

As a member of your design team

• Adding specialized experience to your team
• Immediate help for overflow and quick reaction contracts (QRC)
• Temporary help to get a job rolling while recruiting employees

Independent Design Reviewer

• 90% of project life-cycle cost is determined by decisions made before the first 5% is spent.
• Many companies skip reviews because “everyone is too busy”
• Engineers will do better self-checking when they know others will review their work.
• Outside reviewer can point out issues that co-workers may be reluctant to identify

Business Development and Sales

• Product definition and specification, system analysis
• Proposal assistance
• Red team/Blue team Reviewer
• Demonstrate resource availabilty to your clients for specific expertise
