TOKYO, Jan 24, 2025 - (JCN Newswire via SeaPRwire.com) - Japan Aerospace Exploration Agency, and NEC Corporation, the prime contractor of the laser-communication terminals for the Laser Utilizing Communication System (LUCAS)(1), performed the world's fastest optical communication (wavelength band: 1.5 μm, communication speed: 1.8 Gbps) using LUCAS between the Advanced Land Observing Satellite-4 "DAICHI-4" (ALOS-4)(2) and the Optical Data Relay Satellite in geostationary orbit at a distance of about 40,000 km, and successfully completed the first transmission of observation data to a ground station through the geostationary satellite.Figure 1: Observation image of "DAICHI-4" transmitted by LUCAS. Observed in the initial calibration and validation phase. Downlinked a zonal range of observation data at once, successfully acquired a large amount of data immediately, which would typically require division into multiple paths for direct transmission to a ground station. (Above images, processed with pseudo-color, such as the sea ice of the Arctic Ocean are enlarged to highlight a specific portion of observation area). ©JAXAIn October 2024, JAXA and NEC successfully achieved the optical inter-satellite communication(3) between "DAICHI-4" equipped with the Optical Leo Laser Communication Terminal (OLLCT) dedicated to an Earth observation satellite and the Optical Data Relay Satellite equipped with the Optical Geo Laser Communication Terminal (OGLCT) dedicated to a geostationary satellite, and we have continued technical demonstrations. As a result, we successfully transmitted "DAICHI-4" observation data using optical communication. The success of this data transmission utilizing LUCAS enables immediate downlinking of a large amount of observation data which is difficult to achieve through direct communication to ground stations in areas lacking accessible ground stations. Figure 1 shows the first image downlinked through LUCAS, generated from a large amount of mission data observed by "DAICHI-4" over approximately 30 minutes, traversing the Arctic, Europe, and the African continent. While direct transmission to ground stations requires multiple transmissions, the use of LUCAS narrowed the acquisition of observation data of vast areas to a single transmission.OGLCT: Laser-communication terminal aboard the GEO (Geostationary) satellite(Optical inter-satellite communication instrument for GEO satellite)Above photographs show only the optical components of the laser communication terminals mounted on the exterior of the satellites.The optical component of OLLCT is smaller than that of OGLCT, resulting in improved mountability due to its reduced size.Fig. 2: Overview of LUCAS ©JAXA/NECLaser light has a bandwidth that is orders of magnitude wider than that of radio waves (5 THz in the 1.5 μm wavelength band), allowing it to transmit more information than radio waves. In addition, by using highly focused beams, there is little risk of interference or eavesdropping. The use of laser light is essential for achieving high-speed, high-capacity communications in space in the future. In LUCAS, optical communication has been adopted in the data relay system onboard the geostationary satellite. By using optical communication between the Earth observation satellite and the geostationary satellite, LUCAS enables data transmission from the Earth observation satellite at "1.8 Gbps", that is a speed 7.5 times faster than the "240 Mbps" transmission rate of the Data Relay Test Satellite "KODAMA" (DRTS)(4) using previous generation radio waves. (Figure 3)Figure 3: LUCAS enables high-speed/large-capacity data transmission at a speed of 1.8 Gbps via optical communication © JAXA/NECThere is a distance of about 40,000 km between "DAICHI-4" in low orbit and the Optical Data Relay Satellite in geostationary orbit. The acquisition and communication of the counterpart satellite, which is moving at high speeds, requires precise optical systems and their control technology. Specifically, while the Optical Data Relay Satellite in geostationary orbit at an altitude of about 36,000 km moves at about 3.1 km/second and the Earth observation satellite in low orbit circles at about 7.6 km/second, it is essential to continuously direct the laser beam, which expands only about 500 m, accurately to the counterpart satellite even at a distance of 40,000 km. To achieve this, high-output optical amplification technology for the laser light and acquisition and tracking technology to direct the laser light towards the counterpart satellite are required.In this project, NEC developed the overall system design of LUCAS and both the laser communication terminals for the Optical Data Relay Satellite and the Earth observation satellite, the key components of LUCAS(5). The use of the 1.5 μm band, which is the hallmark of LUCAS, was based on NEC’s development achievements in terrestrial and underwater optical fiber communication systems and was also developed in anticipation of integration with this system in the future. Although the 1.5 μm band is relatively deficient in power efficiency, the recent success in long-distance high-speed transmission between the geostationary satellite and the low earth orbit satellite is expected to accelerate its utilization in space-based optical communication."DAICHI-4" also carries SPAISE3 (Space-based Automatic Identification System Experiment3)(6) developed by JAXA and NEC, which particularly observes vessels in crowded maritime areas. Also for the observation data of SPAISE3, the optical communication makes it possible to transmit a large amount of data in real time. Like this, high-speed data communication using LUCAS contributes to the utilization and promotion(7) of not only SAR data but also various data of other satellites, thereby playing a role as a social infrastructure that protects people's lives and safety.JAXA and NEC have been engaging in optical communication in space since the 1990s. Optical communication in space is also identified as a technology of strategic importance in the Space Technology Strategy formulated by the Japanese government for fiscal year 2023. JAXA has advanced research and development in optical communication as a solution to the increasing capacity and immediacy requirements of data transmission for future Earth observation satellites. NEC has been responsible for designing the LUCAS system, manufacturing laser communication terminals, supporting satellite system tests, and managing the initial functional verification operations of satellite systems. Building on this success, we will continue to contribute to the advancement of Japan's space development by accelerating the technological development of the optical inter-satellite communication in collaboration with related organizations and partners.(1) LUCAS: Laser Utilizing Communication System, developed and being operated by JAXA, is a system that enables data relay between an Earth observation satellite (low orbit satellite) and an optical data relay satellite (geostationary satellite) through optical communication in space using invisible laser light with a wavelength of 1.5 µm. www.satnavi.jaxa.jp/ja/project/lucas/ (Japanese Only)(2) Earth observation satellite developed and being operated by JAXA.

TOKYO, Jan 23, 2025 - (JCN Newswire via SeaPRwire.com) - TANAKA PRECIOUS METAL TECHNOLOGIES Co., Ltd. (Head Office: Chuo-ku, Tokyo; Representative Director & CEO: Koichiro Tanaka), which engages in the industrial precious metals business of TANAKA, has announced the development of the AgSn TLP sheet, a sheet-type bonding material designed for die attachment in the manufacturing of power semiconductor packages. Additionally, the AgSn TLP sheet is anticipated to serve as an alternative to thermal interface materials*1 (TIMs) for large-area bonding in heat sinks, further expanding its potential applications.Sheet Bonding Material That Allows Bonding of High-Current Large Silicon (Si) ChipsIn recent years, there has been rising demand for high-current power semiconductors centered on applications such as electric vehicles, hybrid vehicles, and industrial infrastructure. As such, in the bonding of large Si chips, there are requirements for materials that can allow the bonding of large areas while guaranteeing high reliability. The AgSn TLP sheet announcement declares that it can be used for semiconductor chip bonding of up to 20 mm. Furthermore, it allows bonding at a low pressure of 3.3 MPa, contributing to the improvement of yield in semiconductor manufacturing.Low-Temperature Bonding and High Heat Resistance Required for Power Semiconductors to Contribute to Heat ManagementSemiconductor devices—including power semiconductors—require high heat resistance as high temperatures may cause failures or shorten lifespans. In addition, the primary bonding materials currently adopted in the manufacturing of power semiconductor packages generally include high-lead solder which is being replaced with other materials due to its impact on the environment*2, SAC solder*3 which has low heat resistance, and silver (Ag) sintering agents. The heating temperature of this product is 250 degrees Celsius, allowing transient liquid phase diffusion bonding*4. As the heat-resistance temperature rises to 480 degrees Celsius after bonding, it has higher heat resistance than existing products. It can also be used with various types of bonded materials, as it can maintain a bonding strength of up to 50 MPa. Furthermore, this product is a lead-free bonding material, and it also features high bonding reliability that has passed heat cycle testing of 3,000 cycles.As large-area bonding is possible, besides application as a die attachment material for power semiconductors, it is also expected to be used as an alternative to TIMs. Various materials with high thermal conductivity have been developed for semiconductor package manufacturing, but the low thermal conductivity of TIM materials has been a bottleneck in total thermal design. This product is a bonding material that allows large-area bonding of TIMs above 50 mm and has high thermal conductivity. It can be expected to contribute toward heat management in the manufacturing of semiconductor packages.TANAKA PRECIOUS METAL TECHNOLOGIES is committed to contributing to the development of the semiconductor market, which is expected to expand further going forward. Our dedication to this market ensures that we will continue to innovate and provide solutions that meet the evolving needs of the industry.Specifications of AgSn TLP Sheet________________________________________________________________________________*1 A thermal interface material (TIM) is a heat conducting material inserted between materials to dissipate unwanted heat generated in electronic devices.*2 Although lead is under the scope of regulation by the RoHS Directive, use under a validity period is allowed for applications for which substitutes are not possible scientifically or technically.
