Yes, for several reasons.
Because you might need to make changes to your design to make it easy to manufacture in China, or to have a chance at hitting your budget & timing targets.
And because you need to know what type of supplier you should work with even before starting the search:
- OEM? ODM, already making a very similar product? Contract manufacturer?
- Small, midsize, large?
- Past experience in a certain critical process or technology? In your country’s compliance standards?
