Forming Processes for Ceramic Substrates

Ceramic substrates are generally ultra-thin sheets below 1mm or even around 0.3mm. Forming and sintering are both key difficulties in preparation. The flatness, surface roughness, and dimensional stability of ceramic substrates are key factors that affect the subsequent preparation of copper cladding and circuit etching of the substrate. This places high demands on the forming process of ceramic substrates. At the same time, mass production also requires the forming method to have high production efficiency and low cost.

1. Tape casting process

Tape casting is currently the most important method for forming thin films or sheets.

The basic process of ceramic substrate tape casting is preparing tape casting slurry, vacuum degassing, tape casting, sintering, etc. Tape casting has the dual advantages of high production efficiency and ultra-thinness, but due to the low density of the green body, it is easy to deform when preparing large-sized substrates. The powder forming process combining tape casting and isostatic pressing is used to increase the density of the ceramic substrate tape casting green body, further, reduce the shrinkage of the green body during sintering, and help obtain large-sized high thermal conductivity ceramic substrates.

2. Dry pressing

Dry pressing is to put powder into a mold and apply pressure through a press to press the powder into a green body of a certain shape. The dry pressing process is simple, suitable for mass production, and has a short cycle. The green body has high density, relatively precise size, small firing shrinkage, high mechanical strength of the ceramic parts, and good electrical properties. Dry pressing is suitable for pressing round and thin sheet products. The product has high density and the flatness of the substrate is easy to ensure, but it is difficult to prepare ultra-thin substrates.

3. Gel injection molding

Gel injection molding is to disperse ceramic powder in an aqueous solution or non-aqueous solution containing organic monomers and cross-linking agents to prepare a concentrated suspension with low viscosity and high solid volume fraction (>50vol%), then add initiators and catalysts, inject the suspension into the mold, and initiate the polymerization of organic monomers under certain temperature conditions, resulting in in-situ solidification molding. After low-temperature drying, a green body with high strength and machinability is obtained. Gel injection molding is suitable for the molding of ceramic substrates with a thickness of 0.6 to 10 mm, but the degree of automation and molding efficiency is relatively low. In mass production, the slurry's gravity is generally used as a power source to inject into the mold. The process has high requirements on slurry fluidity, flow mode of injection into the mold, gel time control, green body drying uniformity, etc., and quantitative control is difficult. There are currently few examples of mass production of gel injection molding for substrate molding.

4. Additive Manufacturing 3D Printing

3D printing gets rid of the limitations of molds on traditional molding. In today's increasingly competitive market, 3D printing can achieve frequent product trials and modifications, which has incomparable advantages over conventional processing methods.

Best Capacitors manufacturer in India

Electronic component:

An electronic component is any basic discrete electronic device or physical entity part of an electronic system used to affect electrons or their associated fields. Electronic components are mostly industrial products, available in a singular form and are not to be confused with electrical elements, which are conceptual abstractions representing idealized electronic components and elements. A datasheet for an electronic component is a technical document that provides detailed information about the component’s specifications, characteristics, and performance.

Advantages of Electronic components:

These leads connect to other electrical components, often over wire, to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Basic electronic components may be packaged discretely, as arrays or networks of like components, or integrated inside of packages such as semiconductor integrated circuits, hybrid integrated circuits, or thick film devices. The following list of electronic components focuses on the discrete version of these components, treating such packages as components in their own right.

Classification Electronic components:

Active components rely on a source of energy (usually from the DC circuit, which we have chosen to ignore) and usually can inject power into a circuit, though this is not part of the definition.[1] Active components include amplifying components such as transistors, triode vacuum tubes (valves), and tunnel diodes.

Passive components cannot introduce net energy into the circuit. They also cannot rely on a source of power, except for what is available from the (AC) circuit they are connected to. As a consequence, they cannot amplify (increase the power of a signal), although they may increase a voltage or current (such as is done by a transformer or resonant circuit). Passive components include two-terminal components such as resistors, capacitors, inductors, and transformers.

Electromechanical components can carry out electrical operations by using moving parts or by using electrical connections.

Most passive components with more than two terminals can be described in terms of two-port parameters that satisfy the principle of reciprocity — though there are rare exceptions.[2] In contrast, active components (with more than two terminals) generally lack that property.

Tape-casting: Method for producing electronic ceramic sheets

High-performance ceramic materials have the characteristics of high strength, high hardness, wear resistance, and corrosion resistance, and are widely used in energy, information, aerospace, electronics, biology and medicine, and other fields. The ceramic molding method is an important factor in determining ceramic performance, and tape casting is currently one of the commonly used methods for producing electronic ceramic sheets.

Tape-casting

Tape casting refers to a molding method in which solvents, dispersants, binders, plasticizers, and other ingredients are added to ceramic powder to obtain a uniformly dispersed and stable slurry, and a film of the required thickness is produced on a tape casting machine.

Compared with other molding processes, tape casting has many advantages: the equipment and process are simple and can be produced continuously; single-phase or multi-phase ceramic sheet materials can be prepared; the product has small defects, uniform performance, high production efficiency, and can be operated continuously; uniform It can be produced in large and small batches and is suitable for industrial production. The biggest feature of tape casting is that it is very suitable for the preparation of large thin plate ceramic parts, which is difficult to achieve by pressing or extrusion molding processes. However, there are also some problems with tape casting. The main reason is that the binder content is high, so the shrinkage rate of the blank is large during the discharging glue process, and the thin sheets are prone to defects such as cracking, curling, and uneven thickness.

Tape-casting process

Tape casting was first used in the fields of papermaking, paint, and plastics. It is a long-standing molding technology that mainly includes processes such as slurry preparation, ball mill mixing, molding, drying, degreasing, and sintering.

Process flow chart for preparing ceramic substrates by tape casting

First, the ceramic powder and dispersant are added to the solvent (water or organic solvent), and the particles are agglomerated through ball milling or ultrasonic oscillation, and the solvent is allowed to wet the powder, and then the binder and plasticizer are added, and the particles are obtained by secondary ball milling. Stable and uniform slurry; then the slurry is formed on a casting machine to obtain a green body; then dried to evaporate the solvent, and the binder forms a network structure between the ceramic powders to obtain a green body film; and then the green body is formed The raw film is machined to obtain the specific shape required; finally, the required finished product is obtained through degreasing and sintering.

Application

Due to its simple equipment, continuous operation, high production efficiency, and uniform body performance, the tape casting method has become an important method for preparing large-area, ultra-thin ceramic substrates and is widely used in the electronics industry, energy industry, and other fields.

Also used in monolithic capacitor tiles, Al2O3 substrates for thick film and thin film circuits, piezoelectric ceramic diaphragms, structural ceramic sheets, capacitors, thermistors, ferrite and piezoelectric ceramic bodies, and hybrid integrated circuit substrates. It is also used in the field of mobile phone ceramic covers.

TO-3P/220/247/254/257/258/264 Aluminum Nitride Ceramic Thermal Pads For MOSFET Transistor IGBT Transistor Heat Sink

Innovacera Ceramic Thermally Conductive Interface Pads are designed to provide a preferential heat-transfer path between heat-generating components, heat sinks, and other cooling devices. The pads are used to fill air gaps caused by imperfectly flat or smooth surfaces which should be in thermal contact. The pads are made of ceramic materials such as alumina ceramic and aluminum nitride, which help in providing enhanced thermal conductivity and excellent insulation performance. Typical applications include Power Devices, Integrated Circuit (IC) chip packaging heat conduction,  MOSFET Transistor, IGBT Transistor Heat Sink, MOS Transistor, heat sink interface, LED board Thermal Interface Material (TIM), Chip ON Film (COF) heat conduction.

TO-3P-220-247-254-257-258-264 Aluminum Nitride Ceramic Thermal Pads Without Hole For MOSFET Transistor IGBT Transistor Heat Sink A ceramic heat sink is a device that dissipates heat-dissipating electronic components in an electrical appliance. The whole structure of the ceramic heat sink increases the heat dissipation area in contact with the air, which greatly enhances the heat dissipation effect, and the heat dissipation effect is better than that of the super copper and aluminum. Ceramics are insulated, resistant to high temperatures, oxidation, acid and alkali, cold and thermal shock, and low coefficient of thermal expansion, ensuring stability in high and low temperatures or other harsh environments. Ceramics can withstand high current, can be high voltage, can prevent leakage breakdown, no noise, will not generate coupling parasitic capacitance with power tubes such as MOS, and thus simplify the filtering process.
