What Powder Properties Matter for Electronics Applications
Conductive pastes, inks and sintered contacts demand powders with high purity and tightly controlled particle size. Oxide films and trace impurities raise contact resistance, so electronic grades are specified at higher purities than general industrial powders and handled to minimise surface oxidation. Particle size governs both printability and conductivity: fine and sub-10 micron copper grades pack densely in a paste, sinter at lower temperatures and print through fine screens and inkjet nozzles without clogging.
Morphology is matched to the process. Spherical particles flow and disperse predictably in paste vehicles for MLCC termination, via filling and conductive adhesives, while flake grades give the particle-to-particle contact needed in polymer thick-film and EMI shielding formulations. Copper is the workhorse for cost-effective conductivity, with silver specified where the highest conductivity or oxidation resistance justifies it. Every batch ships with full chemical analysis so electronic manufacturers can qualify material lot by lot.
