Steve, Thank you. Sorry about that sometimes I forget when I throw out acronyms that not everyone may know what they mean.

PPAP - Production Part Approval Process, is used in the automotive supply chain to establish confidence in component suppliers and their production processes, by demonstrating that: "....all customer engineering design record and specification requirements are properly understood by the supplier and that the process has the potential to produce product consistently meeting these requirements during an actual production run at the quoted production rate." PSW - Part Submission Warrant, The result of the PPAP process is a series of documents gathered in one specific location (a binder or electronically) called the "PPAP Package". The PPAP package is a series of documents which need a formal approval by the supplier and customer. The form that summarizes this package is called PSW (Part Submission Warrant). The approval of the PSW indicates that the supplier responsible person (usually the Quality Engineer) has reviewed this package and that the customer has not identified any issues that would prevent its approbation. This is from: http://en.wikipedia.org/wiki/Production_Part_Approval_Process AECQ100 - Automotive Electronic Committee, Automotive quality is governed by a set of various standards. The most frequent and recognized one is the series of documents published by the Automotive Electronic Committee (AEC). One of these is the AEC-Q100 which describes the tests and conditions electronic components have to satisfy before the automotive qualification can be pronounced. Different grades are defined depending mainly on the operational temperature conditions.
