Ceramic substrates for chip resistors Alumina ceramic substrates for resistors offer advantages such as small size, light weight, low coefficient of thermal expansion, high reliability, high thermal conductivity, and density. They greatly improve the reliability and wiring density of circuits, making them an ideal carrier material for chip resistor components. Ceramic substrates for hybrid integrated circuits Hybrid integrated circuits involve packaging multiple components, with at least one of them being active. These complex circuits are created by installing the components on metal conductor-insulator sheets produced through thick-film or thin-film processes. The substrate provides mechanical support for the circuit, serves as the deposition site for dielectric and resistance materials, and offers mechanical support for all passive and active chip elements. Alumina, beryllia, silicon dioxide, and aluminum nitride are commonly used substrates for hybrid integrated circuits. However, considering cost and performance, alumina substrates with smooth surfaces are widely used. The quality and grades of alumina substrates vary depending on the alumina content. Common options include 99.6% alumina for thin-film circuits and 96% alumina for thick-film circuits. Multilayer co-fired alumina ceramics generally use alumina green sheets with alumina content ranging from 90% to 95% as the base material. Substrates for power devices For packaging power electronic devices, substrates need to provide not only basic wiring (interconnection) functions but also high thermal conductivity, insulation, heat resistance, pressure resistance, and thermal matching capabilities. Metal-ceramic substrates such as DBC (Direct Bonded Copper) and DPC (Direct Plated Copper) have superior performance in terms of thermal conductivity, insulation, pressure resistance, and heat resistance. They have become the preferred materials for power device packaging and are gradually gaining market recognition. The most common substrate material for device packaging is alumina (Al2O3), typically with an alumina content of 96%. Alumina substrates are mature in terms of technology and have low cost. Alumina ceramic substrates for LEDs High-power LED heat dissipation substrates are primarily composed of ceramic substrates. The most commonly used high-power ceramic substrates in the market are LTCC (Low-Temperature Co-Fired Ceramic) and DPC (Direct Plated Copper). Ceramic materials such as alumina and aluminum nitride are used. Alumina ceramic substrates for LEDs possess high heat dissipation and air tightness, which improve the LED's luminous efficiency and lifespan. Their excellent air tightness also provides high weather resistance, allowing them to be used in various environments.

Why use ceramic substrates for microelectronics? Ceramic substrates have great implications in microelectronics. First, the mechanical properties of ceramics used in microelectronics lend themselves to carriers for components. Secondly, the electrical properties of high dielectric constant and low electrical conductivity are useful in today’s electronics.Get more news about Alumina Ceramic Substrate,you can vist our website! First let’s look at the mechanical properties of the ceramics used in today’s electronics: alumina (Al2O3), aluminum nitrate (AlN), and beryllium oxide (BeO). These are used in MPT processes because of their applicability to micro-electronics. They have good thermal conductivity for heat dissipation, resistance to deformation and moisture. FR-4 has a parameter called Tg (glass transition temperature), the temperature of rigid form changes to a deformable form. Ceramics do not deform with respect to temperature. Ceramics also have low thermal expansion which makes it ideal for microelectronic and microwave carriers. Note: although BeO has the greatest thermal conductivity of the ceramics, it is also highly toxic in dust form. Other mechanical properties of ceramics for microelectronics include high fracture toughness and resistance to chemicals. Secondly, the electrical properties of ceramics are appealing to microelectronic designers. Volume resistivity is in the order of 1011 whereas FR-4 is 106 to 10 10 and varies with moisture. The high dielectric constant of ceramics makes for smaller circuitry and is very stable compared to FR-4. Alumina has a lower dissipation or loss factor than FR-4, meaning less power is absorbed by dielectric. The loss factor is comparable to high frequency materials, but the high frequency plastic materials are susceptible to moisture and, therefore, would have more loss over moisture ranges. Ceramics do not absorb moisture and, therefore, have more stable performance. Stable capacitors are one of the many components MPT produces. MPT has designed and assembled thick film circuits on AL2O3, AlN, and BeO with substrate thicknesses ranging from 10 mils up to 80 mils thick. Examples of circuits and parts made on the thick film process are posted at the end of this article and on our web site. These examples include capacitors, thick film resistors, hybrid circuitry, LED circuits, space based circuits, and single board computers. MPT’s engineers can design these items based on customer requirements and mechanical considerations.

Will an unexpected Northeastern lab finding lead to ‘a new frontier’ for electronics design? It was one of those happy accidents of science. Northeastern professor Randall Erb and Ph.D. student Jason Bice were working on a product for a university client—and wound up with an entirely new class of material.Get more news about Electronic Ceramics,you can vist our website! Their discovery of an all-ceramic that can be compression-molded into complex parts—an industry breakthrough—could transform the design and construction of heat-emitting electronics, including cellphones and other radio components. “Our research group’s lives are very much situated at the bleeding edge of technology,” says Erb, an associate professor of mechanical and industrial engineering who heads the DAPS Lab at Northeastern. “Things break a lot, and every once in a while one of those breaks turns out to be good fortune.” Last July, Erb was in his Northeastern lab with Bice, who has since earned a mechanical engineering Ph.D. They were testing an experimental ceramic compound as part of a hypersonic project for an industrial partner when something appeared to go wrong.“We blasted it with a blowtorch and, while we were loading it, it unexpectedly deformed and fell out of the fixture,” Erb says. “We looked at the sample on the floor thinking that it was a failure.” Ceramics tend to fracture (or even explode) from thermal shock when subjected to extreme heat changes and mechanical loading. But their sample had deformed gracefully. “We tried it a few more times and realized that we could control the deformation,” Erb says. “And then we started compression-molding the material and found that it was a very fast process.” Its underlying microstructure uniquely allows the all-ceramic to quickly transmit heat and flow effectively during the molding process. The ceramic can be formed into exquisite geometries and exhibits impressive mechanical strength and thermal conductivity at room temperature, says Erb, whose findings were recently published in Advanced Materials. Erb and Bice are developing the product via their startup, Fourier LLC—named after the French mathematician Joseph Fourier, who studied heat flow in ceramics two centuries ago. Fourier has received a $50,000 Spark Fund award from Northeastern’s Center for Research Innovation. It’s unique: Thermoformable ceramics, from what we’ve seen and read, don’t really exist,” Bice says. “So it’s a new frontier in materials.”The new product has the potential to introduce two industry improvements, starting with its efficiency as a heat conductor that can cool high-density electronics. In general, cellphones and other electronics are fitted with a bulky layer of aluminum, which is necessary to draw heat away from the unit.“Our material can be less than a millimeter thick, which presents a low-profile solution,” Bice says. “It can be molded to conform to the surface that you’re trying to cool.”
