Below are the recommended processing steps for optimal results with the Danish Technological Institute's copper ink material.

 

 

CopperTopic 1 – Handling and thinning

The copper ink container should be stored tightly sealed (-18 °C). Let it slowly heat up (ca. 30 min) and stir before use. Lifetime > 6 months. For thinning, mix with propylene glycol (can impact subsequent steps).

 


 

 

Print af elektronikTopic 2 - Printing

Screen printing (Mesh 100-120). Around 6-10 µm thick layer (120T mesh) is deposited per print.  Slot die coating and doctor blading are also possible.

 

 

 

 

Printet elektronikTopic 3 - Drying

80 °C for 180 s right after printing using convection oven.

 

 

 

 

 

maskineTopic 4 - Heat press curing

Heat pressing (180 °C for 120 s) with non-stick layer between print and press (e.g. baking paper). Ca. 1 bar on an area of 25 cm x 50 cm. Within 1 day after drying.

 

 

 

 

Printet elektronik i kobberTopic 5 - Quality control

Validate anticipated resistivity (ca. 10 mΩ/□/mil on coated PET) and adhesion: (ISO 2409, TQC Sheen Adhesion Test) on coated PET.
