Aluminum pcb manufacturer, High Quality&Customization

Friday, September 20th, 2024

In today’s rapidly developing electronic technology, aluminum substrates, as a key electronic component carrier, play a vital role. Aluminum substrate manufacturers are an indispensable backbone in this field. They provide high-quality products to the electronics industry with advanced technology and strict quality control.

Reasons for the development of aluminum substrate

The continuous updating and improvement of aluminum substrate technology has provided a strong driving force for the development of manufacturers. In terms of thermal conductivity, in order to meet the application needs of different fields, the thermal conductivity of aluminum substrates has been continuously improved, and has now reached more than 180W/mK.

Aluminum pcb manufacturer, High Quality&Customization

In terms of molding and processing technology, commonly used molding processes include cutting, punching and bending, and the continuously optimized molding and processing technology has improved the production efficiency and product quality of aluminum substrates.

In addition, technological innovation has also promoted the diversified development of aluminum substrate products, such as ultra-thin aluminum substrates, high-frequency and high-speed aluminum substrates, flexible aluminum substrates, composite functional aluminum substrates, environmentally friendly aluminum substrates and other new products have emerged continuously, meeting the needs of different industries and application fields.

What are the types of aluminum substrates?

(I) Flexible aluminum substrate

The material system of flexible aluminum substrate is usually a polyimide resin system with ceramic fillers, which can provide excellent electrical insulation, flexibility and thermal conductivity.

For example, in some portable electronic devices that require special shapes, flexible aluminum substrates can better adapt to the internal space of the device, eliminating expensive fixtures, cables and connectors, and reducing overall costs.

At the same time, due to its good flexibility, it can also play an important role in some bendable electronic products, such as foldable displays.

(II) Multilayer aluminum substrate

In the high-performance power supply market, multilayer aluminum substrates are made of multiple layers of thermally conductive dielectrics. These structures have one or more layers of circuits buried in the dielectric, and blind holes are used as thermal vias or signal paths.

Although it is more expensive and less efficient to transfer heat with a single-layer design, they provide a simple and effective heat dissipation solution for more complex designs. For example, in some high-end server power supplies, industrial power supplies and other fields, the heat dissipation requirements are extremely high. Multilayer aluminum substrates can meet the heat dissipation needs of these complex electronic devices and ensure the stable operation of the equipment.

(III) Through-hole aluminum substrate

In the most complex structures, a layer of aluminum can form the “core” of a multi-layer thermal structure.

Before lamination, the aluminum is pre-plated and filled with dielectrics. Thermal materials or sub-assemblies can be laminated to both sides of the aluminum using thermal bonding materials. Once laminated, the completed assembly is similar to a traditional multi-layer aluminum substrate through drilling.

The plated through-holes pass through the gaps in the aluminum to maintain electrical insulation. Alternatively, the copper core can allow direct electrical connection as well as insulating through-holes. This complex structure makes it play an important role in some high-end electronic devices with extremely high requirements for electrical insulation.

What is the dielectric material of aluminum PCB?

The dielectric material selection of aluminum PCB is diverse, designed to meet different performance requirements. Epoxy resin is widely used for its toughness and heat resistance, while polyimide is known for its high temperature stability and chemical stability.

Polystyrene is favored for its low dielectric constant and dielectric loss tangent, while acrylic ester is selected for its excellent light transmittance. In addition, ceramic materials such as alumina, silicon nitride, zirconium oxide, etc. are also commonly used dielectric materials for aluminum PCBs due to their excellent insulation, thermal conductivity, oxidation resistance, and high-temperature stability.

Different dielectric materials have different dielectric constants and thermal properties, which are particularly important for applications in high-frequency and high-temperature environments. Polytetrafluoroethylene (PTFE) and ceramic substrates are particularly suitable for high-frequency and high-temperature environments due to their high temperature resistance and low dielectric constant.

In summary, there are a wide variety of dielectric materials for aluminum PCBs, including epoxy resin, polyimide, polystyrene, acrylic ester, alumina, silicon nitride, zirconium oxide, etc. These materials are selected based on their respective advantages to meet the performance requirements of aluminum PCBs in specific applications.

What is the thermal resistance of aluminum PCB?

The thermal resistance of aluminum PCBs ranges from 1℃/W to 2℃/W. ‌This data is in sharp contrast to the thermal resistance of FR4 PCBs, which ranges from 20℃/W to 22℃/W.

This shows that aluminum PCB is significantly better than FR4 PCB in heat dissipation performance. Aluminum material has good heat dissipation effect, which can effectively reduce the heat generated by electronic equipment during operation and keep components running at a suitable working temperature, thereby improving the stability and service life of the equipment.

What are the production processes of aluminum substrates?

First, the material is cut, and the incoming material inspection is strengthened to ensure that the sheet with a protective film on the aluminum surface is used. After cutting, there is no need to bake the sheet, and it should be handled with care, paying attention to protecting the protective film on the aluminum base surface.

Next is drilling. The drilling parameters are the same as those of FR-4 sheet materials. At the same time, the aperture tolerance must be strictly controlled, especially for 4OZ-based Cu. Pay attention to controlling the generation of flash, and drill with the copper skin facing up.

Then enter the dry film optical imaging link, including incoming material inspection, grinding, filming, board clapping, exposure and development.

When inspecting the board, the circuit surface must be inspected according to MI requirements for various contents, and the dry film on the aluminum base surface must not have film falling or damage.

In the etching process, since the copper base is generally 4OZ, etching is difficult. After the aluminum surface without protective film is taken out of the film stripping liquid, it should be washed with water in time to prevent the alkali solution from biting the aluminum surface.

The production process of the green oil process is grinding the plate (only brushing the copper surface) → silk screen printing green oil (first time) → pre-baking → silk screen printing green oil (second time) → pre-baking → exposure → development → grinding machine pickling soft brush → post-curing → next process.

Before spraying tin, tear off the protective film of the aluminum substrate with protective film, hold the edge of the plate with both hands, and it is strictly forbidden to touch the inside of the plate directly with your hands. Pay attention to the operation to prevent scratches.

What are the characteristics of aluminum substrate manufacturers?

(I) Good processing and production effect

Aluminum substrate manufacturers can make full use of the material properties of the aluminum substrate itself according to the actual processing size to bring better processing and production effects for building material design.

(II) Stable and reliable quality

Aluminum substrate manufacturers focus on product quality and stability, and use high-quality raw materials and strict production standards. They have a complete production system and quality control system to ensure the quality and stability of products.

(III) Advanced production technology

Aluminum substrate manufacturers use advanced production technology and equipment to ensure product accuracy and stability. They have professional sales and technical teams that can provide high-quality products and technical support.

(IV) Energy saving and environmental protection

Aluminum substrate manufacturers focus on the energy saving and environmental protection of their products, and use energy-saving and environmentally friendly materials and production processes. They have strong R&D and technical strength, and continue to launch new energy-saving and environmentally friendly products and technological innovations.

What is the market prospect of aluminum substrate manufacturers?

The continuous emergence of new generation electronic products, such as smart phones, tablets, wearable devices, etc., has higher and higher requirements for heat dissipation performance and thinness. Aluminum substrates, as a metal-based copper-clad laminate with good heat dissipation function, just meet these needs.

The development of emerging technologies such as 5G has also brought new opportunities to the aluminum substrate market. Aluminum substrates, as a metal-based copper-clad laminate with good heat dissipation and electrical properties, just meet the needs of 5G communication technology.

The trend of lightweight vehicles and the expansion of the new energy vehicle market have also brought new opportunities to the aluminum substrate market.

What are the layers of aluminum PCB?

Aluminum-based circuit boards (PCBs) mainly consist of three layers, namely the circuit layer (copper foil), the insulation layer, and the metal base layer. This structure gives aluminum-based PCBs excellent heat dissipation performance and mechanical strength, making them particularly suitable for applications that require efficient heat dissipation and good mechanical properties.

The circuit layer is usually made of copper foil, which is etched to form a printed circuit for assembly and connection of devices. The thickness of the copper foil can be between 1oz and 10oz to ensure the conductivity and load-bearing capacity of the circuit.

The insulation layer is the core technology of aluminum-based PCBs. It uses low thermal resistance thermal insulation materials with a thickness of 0.003″ to 0.006″ inches and has good bonding, insulation and thermal conductivity.

The metal base layer is generally aluminum or copper, which has good thermal conductivity and certain mechanical strength. It can quickly conduct the heat generated during device operation, effectively reduce the operating temperature of the device, and improve the power load and reliability of the module.

In addition, according to the specific application requirements, aluminum clad PCB can be designed as single-sided board, double-sided board or very few multi-layer boards. Single-sided board consists of three-layer structure, while double-sided board adds a circuit layer on this basis, forming a structure of circuit layer, insulation layer, aluminum base, insulation layer, circuit layer.

How thick is aluminum clad PCB?

The thickness of aluminum clad board usually ranges from 0.2mm to 10mm, and the specific choice depends on the number of layers and purpose of the circuit board.

0.2mm to 0.5mm aluminum clad board is suitable for making single-sided circuit boards, 0.5mm to 1.2mm is suitable for double-sided circuit boards, and 1.2mm to 2.0mm is suitable for multi-layer circuit boards.

In addition, common standard thicknesses also include 0.5mm, 1.0mm, 1.5mm, etc. For the PCB board itself, common thicknesses are 0.6mm, 1.0mm, 1.6mm, 2.0mm, 2.4mm, etc.

The standard PCB thickness ranges from 0.031 inches (0.78 mm), 0.062 inches (1.57 mm), and 0.093 inches (2.36 mm), with the most commonly used thickness being 0.063 inches (1.57 mm or 157 mm).

The thickness of conventional PCB finished products is generally between 0.8 mm and 1.6 mm, with 1.6 mm being the most common specification‌.

What are aluminum PCBs used for?

Aluminum substrate PCB (aluminum PCB) is a metal-based copper-clad board with good heat dissipation function. It consists of a circuit layer (copper foil), an insulating layer and a metal base layer. Sometimes it is also designed as a double-sided board or a multi-layer board structure.

The application of aluminum substrates is very wide, covering multiple fields and equipment, mainly including:

1. Audio equipment: used for input and output amplifiers, balanced amplifiers, audio amplifiers, preamplifiers, power amplifiers, etc.

2. Power supply equipment: including switching regulators, DC/AC converters, SW regulators, etc.

3. Communication electronic equipment: suitable for high-frequency amplifiers, filtering appliances, signal transmission circuits, etc.

4. Office automation equipment: such as motor drives, etc.

5. Automotive electronics: used in electronic regulators, igniters, power controllers, etc.

6. Computers: including CPU boards, floppy disk drives, power supply equipment, etc.

7. Power modules: such as inverters, solid-state relays, rectifier bridges, etc.

8. Lamps and lighting: As an advocate of energy-saving lamps, aluminum substrates are increasingly used in various color energy-saving LED lamps.

Aluminum substrate PCBs are particularly favored in high-end electronic devices due to their excellent heat dissipation performance and reliability, and are widely used in various occasions that require efficient heat dissipation.

What are the disadvantages of aluminum PCB?

The main disadvantages of aluminum PCBs include high cost, usually only single-sided panels can be made, electrical strength and withstand voltage are more prone to problems, thermal conductivity test methods and test results are not matched, aluminum substrate material specifications are not unified, copper foil thickness does not meet the standard, and there are more defective products and shoddy work. ‌

1. High cost: The price of aluminum substrates usually accounts for more than 30% of the product price, which is significantly higher than other types of PCBs.

2. Production limitations: Aluminum substrates can usually only produce single-sided boards, and the process of producing double-sided boards is more difficult, which limits their use in some applications.

3. Electrical strength and withstand voltage issues: Aluminum substrates are more prone to problems in electrical strength and withstand voltage, which may affect the safety and reliability of the product.

4. Thermal conductivity test and material specification issues: The mismatch between the test methods and test results of thermal conductivity, as well as the lack of unified material specifications for aluminum substrates (there are CPCA industry standards, national standards, and international standards, etc.), all increase the complexity of production and quality control.

5. Copper foil thickness and defective products: Failure to meet the copper foil thickness standards may lead to problems such as burning circuits. At the same time, due to cutting corners and increasing defective products, the quality control of aluminum substrates has become more difficult.

These shortcomings limit the application scope of aluminum substrates to a certain extent and increase the risks of production and use. Therefore, when choosing to use aluminum substrates, it is necessary to comprehensively consider their advantages and disadvantages, as well as specific application requirements and environmental conditions.

What temp can aluminum PCB withstand?‌

The high temperature resistance of aluminum substrates is related to the materials used, manufacturing process and working environment. Under normal circumstances, aluminum substrates can withstand a wide range of temperatures, but the specific temperature resistance is also affected by factors such as solder paste and lamp quality.

The temperature that aluminum substrates can withstand during welding can reach about 400 degrees Celsius, and the welding time is about 30 seconds to 50 seconds, of which the actual melting time is only 10 seconds, which shows that aluminum substrates can withstand higher temperatures in a short period of time without damaging the components.‌

In addition, aluminum substrates, like other types of PCB boards (such as FR4 boards, copper substrates, etc.), can withstand an ambient temperature range of -40℃ to +150℃.

However, in long-term use, the highest temperature that these boards can withstand is between 120℃ and 130℃‌. This shows that although aluminum substrates and other types of PCB boards can work in a wide temperature range, their performance and life will be affected to a certain extent when working in a high temperature environment for a long time.

In short, as an important component in the field of electronics, aluminum substrates have excellent performance and broad application prospects. I believe that in the future, with the continuous advancement of technology, aluminum substrates will play a more important role in the field of electronics.
