So in terms of this discussion, should we be getting official PPAP (to include PSW) from our plater and material supplier (steel coil)? We always do plate thickness measurement here which is included in the Dimensional Test Results, and I was thinking if I get Control Plan and CQI-11 from the plater along with salt spray test results (they have ISO 17025 certified lab), I thought this would be sufficient. And maybe the same for material supplier if we get Control Plan and hardness and tensile strength test results (which are included in mill certificates), we were thinking it would be enough documentation to support our PPAP to our customer unless our customer has specific requirement of sub supplier (tier 3) PPAP. Our customer assembles the part, not us. We make part of their assembly part and get the product plated (outsourced).

You also don't need to include any of your supplier's process information such as FMEAs and control plans. For suppliers, just include the information needed to verify conformance to specifcations.
