What is conductive ink, the basic knowledge of conductive ink and the principle of conductive ink?

1. Conductive ink is an ink made of conductive materials, which has certain conductivity and can be used for printing conductive dots or conductive circuits.

2. Disperse conductive materials (gold, silver, copper and carbon) in the ink. It has certain conductivity and can be used for printing conductive dots or wires. Gold-based conductive ink, silver-based conductive ink, copper-based conductive ink, carbon-based conductive ink, etc. It has been applied to printed circuits, electrodes, electroplated substrates, keyboard contacts, printed resistors and other materials.

1, gold conductive ink

Gold powder has stable chemical properties and good conductivity, but it is expensive, and its use is limited to thick film integrated circuits.

2. Silver conductive ink.

Widely used in conductive printing of thin film switches.

3. Copper conductive ink

Copper is cheaper than silver, but it oxidizes easily. At present, copper powder treated with oxidation resistance is commonly used. The circuit printed with this ink is not easy to be oxidized, but once it is treated at high temperature, it will lose its antioxidant effect.

4. Carbon conductive ink.

Fillers used in carbon-based conductive ink include conductive tank black, acetylene black, furnace carbon black and graphite. Mainly used for thin film switches and printed resistors.

3. Conductive ink consists of conductive filler, adhesive, solvent and additive.
