Heraeus Noblelight has developed an infrared module that is designed to significantly increase productivity in the printing of electronic products by eliminating the need to change over the curing/drying/sintering module whenever the printing technique, printing ink or base material is changed.

To produce printed electronic components, organic or metallic inks are applied to plastic foils, paper or glass. By curing, drying and sintering, the required conductive properties are achieved and at the same time the coating is firmly joined to the base material.

Curing, drying and sintering are processes necessary to obtain the required conductivity or the semi-conducting or dielectric properties. These processes can be carried out by UV emitters, LEDs, flash lamps, warm air ovens or infrared systems.

According to which type of ink and base material are is used, and which type of printing is employed (sheet fed or offset), the manufacturer must generally replace the curing/drying/sintering source module, or install several different modules, after each change.

The custom-built module from Heraeus features an intelligent control system and minimises this time-wasting effort, as several different drying and sintering processes can be carried out with the aid of a single, custom-built infrared system.

Key product features

  • The infrared solution is available in two versions to allow an individual matching of the system with the ink, material, printing process and feed speed.
  • Version One employs an infrared module that is fitted with only one type of emitter. Here, the requirements for the different applications are realised by means of an intelligent control unit.
  • Version Two features a single infrared module fitted with various types of emitter matched to the heating zones of several drying and sintering zones.
  • Both versions provide controllable infrared power density in the range 20–220kW/m2.
  • Emitter filament temperatures are from 1,200°C to 3,000°C so that the infrared spectrum can be optimally matched with the reflection and absorption characteristics of the inks and the substrates.
  • The optimum distance between emitter and product is also important. With tests, feed speeds of up to 60m/min can be achieved.
