ROHM develops a highly wear-resistant thermal printhead

21ic Semiconductor manufacturer Rom Co., Ltd. recently developed a high-endurance protective film thermal print head "KD2003" which is about 3 times higher in wear resistance than conventional products and has improved durability while preventing scratches and electrolytic corrosion. -DF20A", the sample has been sold since January (sample price: 3,000 yen / piece).
With regard to mass production, it is planned to start mass production of 100,000 units per month from March 2011 and mass production at ROHM Electronics Dalian Co., Ltd. (Dalian, China).

The market for micro-printers continues to grow with the global popularity of POS systems and EFT, CAT, etc. Therefore, the market demand for thermal print heads is also increasing. These thermal papers for micro-printers have a tendency to reduce the cost of maintenance, and the surface of some thermal papers is inferior, which may cause abnormal wear, scratching, and electrolytic corrosion, resulting in thermal The life of the printhead is shortened.
In order to cope with such a situation, measures such as changing the protective film material of the print head to a hard material have been taken. However, the problem of improving the strength of the protective film is the composition of the protective film and the shape design of the heat generating portion. In the past products, when using some inferior thermal paper, the service life is only about 10km, which is of course related to the frequency of use of the printer, but it has not been used for a few months or so. In response to this situation, ROHM has been working to improve the structure and printhead structure of hard materials in protective film materials. The thermal print head developed this time has greatly improved the wear resistance by optimizing the constituent materials and components of the protective film material, and has achieved durability of about 3 times higher than the conventional products (guaranteed 150 km (the previous product is 50 km)). In addition, by increasing the thermal conductivity of the protective film, the printing efficiency is also improved by 15%, and the print quality is also improved. Moreover, the shape of the print head remains exactly the same as in the prior art, so there is no need to change the design of the printer. In addition, this specification can also be used for repair and replacement.

Based on the semiconductor technology and thick film/film film forming technology that have been accumulated so far, ROHM has a wide range of products for POS terminals and various label printers, and has a series of products that meet the needs of different markets such as high-speed printing and high image quality. Highly praised. This new product was developed by broadly integrating the advantages of these technologies, contributing to the maintenance-free system and improved print quality of our customers' systems.

<Explanation of terms>

・Scratch the thermal print head caused by the intrusion of foreign matter. The foreign matter mixed between the roller and the thermal head may cause damage to the surface of the thermal head (scratch scratches). When the damage is large, the electrolysis value of the heating element may be affected, and white streaks may occur during printing.

・EFT (short for Electronic Funds Transfer System)

Electronic account settlement. A system for performing capital movement and settlement processing between accounts through an electronic system. Including settlement by CD (Automatic Teller Machine), ATM (Automatic Teller Machine), etc., automatic withdrawal by corporate banking, home banking, or magnetic stripe card, like online with VISA electronic card when shopping Real-time instant billing and other EFT systems.

・CAT (short for Credit Authorization Terminal)

The CAT terminal is an abbreviation of Credit Authorization Terminal, which refers to the credit authorization terminal of a credit card. The credit card company and the franchise store that sets up the CAT terminal are connected to each other via a communication line, and the terminal for the CAT system that confirms the credit status such as the lost or stolen, the confirmation of the expired card, and the confirmation of the use limit is confirmed in real time.

The connection of the parallel  groove clamp for the medium and small section of the aluminum stranded wire or the overhead stranded wire and the steel core aluminum stranded wire strand in the position where the tension is not applied is also used for the jumper connection of the non-linear tower. Parallel Clamp is a parallel connection wire to transmit the electrical load of the contact fittings.
