| Product Name | 3-11 µm Nickel-Coated Conductive Polymer Microspheres with 0.25 µm Increments |
| Catalog No. | IGM-HMM-0270 |
| Description | Alta DiagnoTech conductive microspheres combine a monodisperse polymer core with a strongly bonded nickel shell. Uniform particle size, controlled elasticity and low electrical resistance support reliable vertical conduction between closely spaced electrodes. |
| Intended Use | Microcircuit interconnection, vertical conduction between liquid-crystal display substrates, anisotropic conductive films and anisotropic conductive pastes. |
| Principle / Technology | Compressible conductive contact formed by a nickel-coated polymer microsphere. |
| Performance Range / Specifications | The overview states 3.0-11.0 µm sizes at 0.25 µm increments. The repeated parameter table lists 3.00-10.00 µm, CV ≤3.5%, 10% compression modulus approximately 450 or 500 kgf/mm², nickel thickness 100-150 nm and metal content 25-35% or 30-40%, depending on size group. |
