Despite using the same thermal conductive silicone, - Evaluation results are unstable - It performed well in prototypes, but there is performance variation in mass production Such troubles are actually not uncommon. Many of the causes are due to storage and handling conditions rather than "material quality." Thermal conductive silicone is not just a "bonding and coating material," but a functional material precisely designed to meet design specifications. In other words, it is a material that only exhibits catalog performance when used correctly. ■ Thermal Conductive Silicone is a "Functional Material" Thermal conductive silicone is not just a paste-like material; it is a high-performance material designed as a composite material. Its performance is established not by a single component but by a precise balance of multiple elements. The main components are as follows.

Modern advanced technology relies on precisely manipulating parameters such as the wavelength, direction, and intensity of light. At the center of this light control is the optical mirror. The basic function of an optical mirror is to reflect incident light in a specific direction with high efficiency, but it goes beyond being just a reflective surface. Depending on the application, advanced optical performance is required, such as "which wavelengths to reflect or transmit," "how much reflectivity to achieve," and "how accurately to focus and form images." - The role and importance of optical mirrors - The two main types of mirrors: metallic mirrors and dielectric mirrors - Metallic mirrors: basics and characteristics of reflection - Dielectric mirrors: technologies that achieve high reflectivity - Comparison table: contrast between metallic mirrors and dielectric mirrors - Specific examples of differentiation based on applications - Summary and outlook: the importance of technology selection and contributions to industry For more details, please visit our company website.

Optical filters are important devices used to extract only the necessary wavelengths from light or to block unnecessary wavelengths. They are utilized in a wide range of fields, from cameras and displays that we commonly see, to spectroscopic analysis devices used in medical and bio fields, as well as in industrial applications such as laser processing and optical communication. Light encompasses a broad wavelength range, including ultraviolet, visible, and infrared light; if the desired light cannot be precisely controlled, it can lead to issues such as false detection, increased noise, and decreased image quality. This is where the concepts of "cut-on" and "cut-off" come into play. These concepts indicate the boundary where light begins to transmit and the boundary where transmission ends, forming the foundation of optical filter design. 1. Definition and Basic Principles of Cut-On and Cut-Off The most important parameters for correctly designing and evaluating optical filters are the "cut-on wavelength" and "cut-off wavelength." These are not just names; they are reference values that numerically define the effective performance of the filter, specifically which wavelength ranges are transmitted and which ranges are blocked. 2.

Momentive's "TIA0330" is a non-corrosive, fast-drying, heat-dissipating one-component room temperature curing silicone adhesive with reduced low molecular siloxanes. It reacts with moisture (water) in the air to cure into a rubber-like elastomer that excels in heat resistance, cold resistance, electrical insulation, weather resistance, and water resistance. It requires no mixing or heating, significantly simplifying the process from application to curing. Its semi-fluidity makes it suitable for automatic dispensing and it has excellent conformability to complex shapes. It is ideal for a wide range of electronic devices where heat dissipation is critical, such as automotive ECUs, inverters, communication base stations, and servers/PCs. At Adachi New Industries, we provide consistent technical support from material selection based on application to optimization of application conditions and prototype follow-up. If you have concerns regarding heat dissipation design or adhesive challenges, please feel free to consult us. *About the corrosion mechanism of general silicones Corrosion of copper-based metals by silicone occurs when moisture-curing silicones react with water vapor in the air, releasing by-products such as acetic acid and alcohol. When these components come into contact with the copper surface, they undergo a chemical reaction, forming copper oxide and corrosive compounds. Corrosion accelerates, especially in energized environments or high humidity, leading to poor conductivity and contact degradation.

Momentive's "TIA235R" is a two-component addition-type liquid silicone rubber designed for heat dissipation and insulation sealing of electrical and electronic components. By mixing component (A) and component (B) in a 1:1 ratio and curing at room temperature or with heat, it hardens into a rubber-like material and adheres to various substrates. After curing, it exhibits excellent heat resistance, cold resistance, and weather resistance, demonstrating stable heat dissipation and electrical insulation properties over a wide temperature range.

When considering heat-dissipating silicone, the first thing that often draws attention is the value of "thermal conductivity (W/m·K)." While thermal conductivity is indeed an important indicator, in actual implementation environments, there are not a few cases where "even if the thermal conductivity on the catalog is high, the temperature does not decrease in the actual device." The reason for this is that heat dissipation performance is determined not by the physical properties of a single material, but by a combination of multiple factors such as: - Contact conditions - Compression conditions - Coating thickness - Interface conditions - Aging changes Therefore, understanding that "high thermal conductivity does not equal the optimal solution" is the starting point for selecting heat-dissipating materials.

The UV-IR cut filter is an optical thin-film filter that selectively removes unwanted light in the ultraviolet (UV) and infrared (IR) wavelength ranges, allowing only specific wavelength bands of light to be transmitted or reflected with high precision. This filter achieves wavelength selectivity by utilizing interference effects through the precise layering of multilayer dielectric films and metal films. Generally, it requires control of film thickness on the order of nanometers, exceeding several tens to over a hundred layers, and its optical properties are determined by multiple parameters such as film thickness accuracy, refractive index of the film material, smoothness of the film interfaces, and adhesion of the films. 1) What is a UV-IR cut filter? 2) Historical background of UV-IR filter manufacturing in Japan 3) Why has overseas manufacturing of UV-IR cut filters progressed? 4) If UV-IR cut filters were to be produced again in Japan... necessary points (hypothesis) 5) Technically important points when selecting UV-IR cut filters 6) Future prospects Conclusion - The efforts of Adachi New Industry Co., Ltd. to focus on domestic production in Japan For more details, please visit our company website.

As the high integration, miniaturization, and high output of semiconductor devices rapidly advance, "thermal management" has become one of the most critical parameters that directly affects product reliability, lifespan, and safety, rather than being a secondary design issue. With the miniaturization of transistors, current density has been increasing year by year, and in the power device sector, the widespread adoption of SiC and GaN has led to higher allowable operating temperatures, while heat generation density (W/cm²) has certainly risen. As a result, issues such as increased junction temperature, the emergence of hotspots, and stress concentration due to temperature gradients have become more serious problems than ever before. For example: - Power modules in EVs and charging infrastructure - High-heat chips in AI accelerators and GPUs - High-density mounted boards in automotive ECUs - LED modules with increasing brightness - Industrial power supplies and inverters Despite being in different fields, they all share the commonality that we have entered an era where "thermal design determines the performance limits of products." This is not just about lowering temperatures... For more details, please refer to AD-Chemi.
