SEAIN IND Concludes Participation in International Fastener Expo 2026

China, 3rd Nov 2026 – A thinner thermal interface looks like a straightforward way to reduce resistance between a processor and its cooling hardware. For the engineer developing the material, that goal quickly becomes a formulation problem. The filler has to fit the gap, and the mixture still has to flow into place. Choosing a finer diamond powder can help with the first requirement while making the second harder.

Suppose a TIM formulation contains coarse particles that keep an assembly from reaching its intended bond-line thickness. Moving to a finer distribution seems reasonable. At the same filler volume, however, smaller particles expose more surface for the matrix to wet. Viscosity may rise, and a mixture that worked through the dispensing equipment may become difficult to process. The thinner layer now depends on solving a different problem.

This is where Diamond Powder belongs in thermal management: as a filler dispersed in a matrix for thermal interface materials, thermally conductive adhesives, gap fillers, encapsulants, or potting compounds. It is a formulation ingredient, distinct from a CVD diamond sheet attached near a chip. The finished material gets its behavior from the combination of filler and matrix, including how they are mixed and assembled.

Thermally conductive diamond powder for evaluation as a filler in thermal management formulations.

A smaller particle changes the whole mixture

The nominal particle size tells only part of the story. A small population of oversized particles can hold a thin interface open. Agglomerates can interfere with dispensing even when the individual particles are fine enough. Looking at the full particle-size distribution and the dispersion after mixing helps explain behavior that an average size can hide.

Heat also has to cross the boundaries between diamond and the surrounding matrix. Diamond’s intrinsic thermal conductivity describes the solid material; the formulation contains polymer between particles and resistance at their interfaces. Changing particle size changes that network. A finer powder can therefore improve the achievable bond line without necessarily improving the mixture’s bulk thermal conductivity. Those are separate effects, and either can influence the assembled interface.

Adding more filler introduces another tradeoff. Higher loading can improve conductive pathways, yet it also leaves less matrix available to wet the particles and carry them through processing. Poor flow or trapped air can undermine the expected benefit. A formulation engineer has to find a workable balance between thermal transport and the consistency needed on the production line.

A blend of sizes offers room to adjust that balance. Smaller particles can occupy spaces between larger ones, changing packing behavior and potentially allowing more solids. Whether that helps depends on the proportions and surface condition as well as the mixing process. An added fine fraction may instead raise viscosity. Packing is useful because of what it enables in the formulation, rather than as an isolated target.

The application determines how much processing freedom is available. A thin TIM over a processor faces a different gap and assembly pressure from a thick gap filler. A potting compound has to flow around components inside a cavity. Carrying the same powder choice across these applications can overlook the feature that made it useful in the original recipe.

Surface treatment deserves a place in that discussion. A change intended to improve wetting can also affect adhesion or electrical behavior, so it needs evaluation in the selected matrix.

Find out which change produced the result

For the thin-interface project, the first comparison can hold the matrix and filler volume constant while changing the particle-size distribution. Keeping preparation and cure conditions consistent makes the result easier to interpret. If the finer material then needs a lower loading to dispense, that becomes a second formulation comparison. Report loading consistently as a weight or volume fraction so the difference remains clear.

Measure thermal behavior at comparable thickness, pressure, and temperature. Thermal impedance includes the layer and its contacts; measurements at several thicknesses can help distinguish bulk behavior from contact resistance. Pair those results with the bond-line thickness actually achieved during assembly. A value from a thick specimen alone leaves the original thin-gap question unresolved.

Electrical insulation and durability belong in the finished-material evaluation. The matrix and any other additives affect dielectric behavior, while aging can change the interface after assembly. Pump-out may matter for a compliant TIM; adhesion or cracking may be more relevant to a cured adhesive. These checks follow the application rather than the powder description.

Engineers reviewing Yorsuma’s diamond material range for a formulation trial can start with the matrix and the gap they are trying to fill. Explaining whether the current limit is dispensing, bond-line thickness, or measured thermal resistance gives the material discussion a useful direction. The better powder is the one that helps the formulation work in that assembly, with the result established through formulation trials and representative hardware testing.

Diamond Powder Particle Size Tradeoffs in Thermal Interface Materials

Founder Evan Valemont will continue to lead the investment education division

United States, 3rd Nov 2026 – Valemont Invest Inc. announced that its investment education division will hold an online opening ceremony on November 7, 2026, to formally launch its fourth-quarter education program. Founder Evan Valemont will continue to lead the division. The program is designed to help investors understand market developments, evaluate investment opportunities and take a more structured approach to risk management and trading decisions.

According to the company, instruction will begin with practical questions about individual stock movements, the durability of market themes and rebound signals, then explore the relationships among capital flows, sector rotation and business performance. The program will invite seasoned financial market experts to participate in livestreams, connecting specific market developments with the decisions investors face in their day-to-day activities.

In an interview, Evan Valemont said the program aims to help investors clarify the reasoning behind buying, setting stop-loss levels, holding and exiting: which opportunities warrant participation, at what price level losses should be limited, what developments support holding a position and when an earlier decision should be reassessed. He emphasized that understanding the forces behind market moves can help reduce the influence of price swings and emotion on decision-making.

The program will also incorporate CortexQuant (CQ), the company’s internally developed research support system, as an instructional tool. It will help illustrate the research process, from interpreting market information and articulating an investment rationale to assessing risk. Instruction will emphasize the conditions that support a judgment and how to reassess a view when circumstances change, helping participants understand the connection between the analysis and its conclusions.

Instruction on trade execution will connect stop-loss planning and position sizing with individual risk tolerance. Topics will include defining the investment rationale and acceptable loss before buying, identifying developments to monitor while holding, and distinguishing among achieving an objective, rising risk and a change in the investment thesis when exiting. Interest rates, corporate earnings and cash flow will also be covered to help participants understand how market expectations form and evolve.

Seasoned financial market experts will participate in accompanying livestreams focused on market developments and their underlying drivers. Valemont said the sessions are intended to show participants how researchers frame questions, assess the significance of information and examine different perspectives, connecting the methods taught in the program with observations of actual market conditions.

The quarterly program will also address ongoing monitoring and post-trade review, helping participants revisit their initial judgments, the actions they took and the eventual outcomes to identify areas for improvement. By combining classroom instruction with follow-up discussions, the company aims to translate research approaches into learning methods investors can continue to apply.

Valemont concluded by reaffirming the company’s mission: “Structure creates clarity. Technology makes it scalable.” He said the program will follow that direction, using clearly organized instruction and supporting technology tools to help participants understand complex market issues.
