Direct part marks (DPMs) and their quality are critical for tracking and traceability efforts as well as maintaining compliance with government and industry regulations. Poorly marked DPMs can halt production, jeopardize compliance, and introduce defects into the manufacturing process.
This whitepaper provides a clear understanding of DPM regulations, how to achieve and maintain compliance, as well as best practices for marking and code verification.
