Most clients that we work with have a proprietary device or perhaps a concept for such device that requires an interfacing high frequency power source. Selecting an outsource contractor to work with you on a development project is a decision that should be done with as much due diligence as possible.
Larger clients have a formal review process and others have a more unstructured approach.
Knowing our business, we can only tell you how we would go about it. Policies regarding this issue vary between contractors. Even though we are a speciality contractor, it is our policy not to take on projects for competing products or applications while we are actively engaged with a client. We like to feel that when you contract with us we are like your partners and our mutual interests should be the same. These distinctions are not always clear to a layman, nor would you expect them to be.
