Silver Coated Poly(Methyl Methacrylate) microspheres with conductive coating are available in sizes between 45um and 750um in free-flowing dry powder form. PMMA cores with conductive silver coating are ideal where some deflection is
required while maintaining conductivity and compliance. These particles can be used as conductive spacers in bondline applications. Offers benefits for Ansiotropic Conductive Film (ACF) applications, creating conductivity in one direction. The combination of the thick coating of the silver and the bonding to the compliant deformable polymer sphere offers a durable solution.
Sphericity varies by Product Code:
