DFM, structure, temperature rise, fixtures, and samples timed to the customer’s build gates.
Engineering reviews the drawing for DFM, then works the structure, the current path, and the temperature rise. Fixtures are built with the part, and the sample is made in-house.
Validation covers type tests, reliability tests, and process work on dipping and insulation. Drawings are kept under version control, and a confidential program stays inside the project group.
Sample timing follows the customer’s build gates, from the first review to the lot that goes to volume.
