IPC-6016 document establishes the specific electrical, mechanical and environmental requirements for organic HDI layers with microvia technology. The acceptance criteria of the HDI layers are organized into specification sheets that reflect typical end-use applications, such as cellular phones, avionics, automotive and personal computers. Key concepts include: HDI conductive surface requirements, microvia integrity, HDI electrical properties and end use application slash sheets. For use with IPC-6011-6012. 55 pages. Released May 1999.
