Adhesives Research Develops Two New Electrically Conductive Adhesives

Adhesives Research has developed two new electrically conductive adhesives – ARclad 92262 and ARclad 92264 – for use in personal communication devices and other electronics applications that require highly reliable conductivity.

ARclad 92262 is a 1.8-mil (0.045 mm) conductive acrylic adhesive with low volume resistance to provide excellent bonding for EMI shields, ground plane assemblies and electrical interconnections. ARclad 92264 is a 2.0-mil (0.05 mm) conductive acrylic adhesive specifically designed for capacitance sensors, multi-pin connectors and other fine pitch signal applications as an alternative to anisotropic conductive films (ACF) that require heat and high pressure to apply, which can damage components. ARclad 92264 allows for overlapping of multiple contacts without electrical cross-talk occurring.

Both of these conductive adhesives offer highly consistent electrical interconnects and reliability across a range of environmental conditions such as high temperatures and humidity without swelling. They exhibit excellent adhesion to film and metal substrates, including Kapton, gold and stainless steel, with oxide penetration that allows the adhesives to make good contact with metal. No heat is required to apply these adhesives, so there is less risk of damage to the sensitive, expensive components in communications devices.

After initial lamination to a substrate, the adhesive requires no additional mechanical pressure to maintain a reliable electrical contact. ARclad 92262 and ARclad 92264 are recommended for use in electronics applications such as mobile phones, computers, PDAs, disk drives, modems and automotive electronics. Adhesives Research can customize the products to meet the specific application needs of customers.
