In Case You Missed It

摘要

Anisotropic conductive adhesives make both the mechanical and electrical connection between two devices. They have been shown to provide mechanical connections at peel strengths up to 20N/cm, electrical connections at pitches down to 0.035mm pitch with minimum 0.010mm space between contacts and minimum 1500um2 contact pitch. The typical contact resistance is 5-7mn for Au-Au bonds; 10-8Ω (10-7Ω after aging) electrical isolation. Under study, electrical characteristics are good at >20Ghz frequencies. Adhesives are typically epoxy for medical applications, but are also available in acrylic/ epoxy hybrids and as hot-melt adhesives. Particles can either be solid metal particles or Ni Au plated compressible plastic spheres. (MEPTEC 2011 Medical Symposium, September 2011).
