With the innovative concept known as “Super Thinkingâ€, Japan ROHM (Rom) innovation in the field of components will always bring new surprises to the industry. At the booth of Rom at CEATEC in Japan, ROHM exhibited a wide range of innovations in a wide range of products including ICs, discrete semiconductors, optical semiconductors, electronic components and modules.
Silicon carbide products achieve performance improvements
Among the products exhibited by ROHM, the most eye-catching is the low-power Schottky barrier diode (SBD) "SCS110A series", MOSFET and IPM (Intelligent Power Module). They use SiC (silicon carbide) materials, and SiC is expected to become the next generation of power component materials due to its low power consumption and high withstand voltage. According to the introduction of the management of the planning department of Roma Semiconductor (Shanghai) Co., Ltd., the history of SiC materials is mainly in two aspects: First, the on-resistance is low, about 1/5 of silicon. The second is to work normally in a high temperature environment of 250 degrees Celsius, so it can be widely used in power transformers, converters, PFC circuits (power factor correction circuits) and other fields such as solar power generation in electric vehicles/hybrid vehicles. Compared with other companies, ROHM's SiC-SBD achieves a significant improvement in forward voltage and action-time impedance.
Ueda Farming also told reporters that Roma acquired the SiC wafer supplier last year, SiCrystal of Germany. The pre- and post-process of SiC was done by the branches of Roma Japan and Thailand respectively, so that Rom established SiC devices. One-stop production system. ROHM regards SiC component technology as one of the core technologies of the next-generation semiconductor business, and will continue to promote the SBD withstand voltage characteristics and strengthen the lineup of high-current products. In addition, ROHM will strengthen the power device field and accelerate the mass production of SiC-related products such as MOSFET and IPM.
LED products achieve the smallest and thinnest
ROHM has been manufacturing and selling LEDs since 1973 and has been leading the world in ultra-small LEDs. This time, Roma showed the world's smallest and thinnest patch LED PICOLED-mini series. It uses ROHM's unique high-brightness component technology and ultra-precision machining technology to achieve ultra-small, ultra-thin LED chip and package, reducing installation area by 70%.
In addition to the PICOLED-mini series of ultra-small SMD LEDs, ROHM also demonstrated the 1W and 3W high-power LED "SSML Series" for LED lighting and the mid-power LED "PSML Series" for TV backlighting. Introduction of Ueda Farming History, 1W samples have been launched, 3W products are under development and will be launched soon.
In addition, ROHM also expanded its diversified market and launched its first LED lighting product. This product has adopted the three-dimensional design technology and has applied for a patent. Ge Tianyi, the Chinese business headquarters of ROHM Co., Ltd., has three advantages: one is that the illumination is wide, the general lighting product has a light diffusion angle of 140 degrees, and the ROHM product can reach 220 degrees; the second is more energy-saving, 6W. The brightness of the bulb is comparable to that of a normal 80W fluorescent lamp; the third is a longer life, up to 40,000 hours. Currently, only Roma and Osram have developed such products worldwide, and their average selling price is about 3,000 yen.
ROHM also demonstrated the single-chip optical proximity/illuminance sensor IC "BH1771GLC" for non-contact motion detection for devices such as mobile phones and digital cameras. Ge Tianyi also told reporters that in response to the current situation that Japan is at the forefront of 3D TV, Roma has also developed a driver IC for 3D glasses.

The Tape Measure is too deformed and will not fail. Why didn't it fail? The spring in the tape measure is very long, and it is completely relaxed to completely tighten the range. The entire stroke of the tape measure includes it, and there is margin at both ends, so the tape measure will not fail.
There is no difference in tension between a one-meter length and a two-meter length; the spring of the tape measure is very thin, and the amount of deformation when it is tightened is very small, so the reaction force is very small, and no force change is felt when the rule is pulled.
