Conductive ink before the application of intelligent machinery market

[ppzhan Abstract] The application prospect of smart ink is very considerable, but there are still many technical obstacles in the application of smart ink. Some obstacles are not problems with the ink itself, but print problems. The more intelligent the ink, the harder it is to print with them. For example, printing with heat sensitive inks used in low temperature environments is very difficult because it must be printed at room temperature.

At a printing conference on smart labels in Europe, DanLawrence, a manufacturer of FlintInk inks, said, "As technology advances, inks will likely replace some of the growing electronic components in electronic devices. For integrated circuits, Maybe as we know, it will probably be completely replaced by ink."

They have no visual utility and have been excluded from the printing field. However, traditional printing techniques and digital printing techniques are now being applied to the production of smart labels. Although the current production is small and very small, we believe that in the near future, ink will have an invaluable application prospect in the large-scale manufacturing of electronic data products, and this application will also partially change printing. The type of method and ink.

This technology has already been available for the production of large-scale electronic materials, which is sufficient for the new era of sophisticated and inexpensive electronic components to meet the needs of the market. The printing industry has a long way to go from the current printing of a large number of image products to the electronics manufacturing industry.

An ordinary printer or printer cannot suddenly become a device for making electronic materials. But it is not unimaginable that in a fairly clean workroom, presses made by Heidelberg and other digital printing equipment manufacturers will be able to produce electronic products.

The new business of printed electronics is not only a revolution in the printing industry, but also a revolution in the electronics industry. By then, the production of electronic products will be a series of printing jobs scattered around the world, just like the current printing industry, rather than just a few large manufacturers like microchips and integrated circuits.

Smart labels in the world market will mainly exist in electronic article surveillance (EAS) and radio wave identification (RFID) systems. EAS is mainly used in anti-theft devices in the retail industry, and RFID is mainly used to portray and track bulk goods through the supply chain.

Another major market for smart labels for conductive ink printing is in diagnostic applications. For example, on some devices that display changes in temperature, pressure, light, and humidity, and on devices that detect the presence of viruses, bacteria, and gases. Some photochromic or thermochromic inks have been developed which use these inks to change color when subjected to light treatment, disinfection or curing. In hospitals, such ink-printed labels can be used to verify the cleanliness of medical devices and equipment.

At Ford Motor Company, because the polyurethane suspension material (a coating) is subjected to a heat curing process on the production line, it is difficult for the staff to correctly judge whether the curing process is just right, so there will be many vehicles whose quality is not enough, resulting in vehicle recall. The loss is great. They adopted the advice of a specialty ink company. Before the curing process, a self-adhesive cycle 'point' has been added to each part, which starts to be reddish and turns black after the correct time of heat curing. In the effective removal of the uncured part of the process, Ford Automotive companies have proven the reliability of this method in practice.

There are also some smart labels printed with conductive inks to help people determine whether the sun's rays are suitable for human skin and prevent exposure. Mainly some stickers, attached to the skin, can test the safety of the sun's strength on a certain type of skin, beyond which the sticker will change color.

The application prospect of smart ink is very considerable, but there are still many technical obstacles in the application of smart ink. Some obstacles are not problems with the ink itself, but print problems. The more intelligent the ink, the harder it is to print with them. For example, printing with heat sensitive inks used in low temperature environments is very difficult because it must be printed at room temperature.
