Custom-Built Infrared Emitters for Printed Electronic Components

02.08.2013
Intelligent Solutions for Drying and Sintering Processes

Printed electronic components and printed features of electronic products are very much on the increase, providing RFID (radio frequency identification), as integral features of telephone- and credit cards (smart cards), providing protection against copying or as security features in identity cards and passes.

To produce such printed electronic components, organic or metallized 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.

A newly developed infrared system, including an intelligent control unit, meets all important requirements, and this new module was shown for the first time at the LOPE-C exhibition which took place in June.

All conventional printing processes, such as screen printing, inkjet, gravure and Flexo, can be used to produce printed electronic components. The inks used are organic or metallized inks and these can be used with many materials such as paper, plastic foil or glass. 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, hot air ovens or infrared systems.

According to which type of ink and base material 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.

An innovative infrared system, including an intelligent control unit, can minimize this time wasting effort as several different drying and sintering processes can be carried with the aid of a single, custom-built infrared system. This new 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 1 employs an infrared module which is fitted with only one type of emitter. Here the requirements for the different applications are realized by means of an intelligent control unit.

Version 2 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 to 220kW/m2. Emitter filament temperatures are from 1,200 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 60 meters per minute have been be achieved.

With both infrared system versions it is no longer necessary to change the emitter, module or other components when changing over between different processes. This significantly raises a system’s productivity.

Infrared Systems Offer Significant Advantages in Printing Electronic Products.
Infrared emitters transfer energy in a contact-free manner and generate energy only in the product to be heated. They can be excellently matched with different functional materials and substrates in terms of wavelength, power and shape. Very fast response times minimize material damage in the event of unexpected feed belt stoppage or breakage.
Modern numerical methods such as Ray tracing and Computational Fluid Dynamics (CFD) are used to ensure that heating is as homogenous as possible. The energy distribution over the material surface can be optimized, for example, by carrying out simulations prior to installation. Sophisticated reflector technology also helps to ensure that the energy is applied in the best way possible.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
