HDI Fabrication Problems, Quality Control and Reliability Issues by Happy Holden

What you will learn:

HDI definitions, types and markets: Not all HDI products are the SAME!

History of HDI: It helps to understand why HDI was developed in 1982

HDI fabrication problems and issues: Some of the hurdles

  • Via formation mechanical and laser drilling quality- scoring quality in various materials
  • Metallization desmear, electroless copper, direct metalization and semi-additive processing
  • Imaging and etching achieving fine lines and spaces, controlled copper etch
  • Electrodeposition improved throwing power, enhancing through hole and microvia plating
  • Reliability issues
  • The use of coupons
