In the process of manufacturing PCB, FPC and other precision industries, press pads are important auxiliary materials for thermal compression bonding processes. It not only affects the uniform distribution of pressure, but also determines the heat conduction effect, lamination stability, and finished product quality. Therefore, how to choose the appropriate press pad has become a key issue of concern for PCB manufacturers, electronic packaging companies, and other related industries. For standard PCB manufacturing, paper pads are more common due to their economic and disposable characteristics. For high-end PCBs such as HDI and multi-layer boards, rubber press pads and aramid fiber pads are better choices because they can provide better pressure dispersion and thermal conductivity performance. For 5G, IC carrier boards, and high-frequency high-speed PCBs, graphite press pads have become the mainstream choice due to their superior thermal uniformity, which ensures higher production yield.

In the manufacturing process of printed circuit boards (PCBs), the lamination process of multilayer boards is crucial. As a key step in connecting the circuits of each layer, the quality of lamination directly determines the reliability, stability, and electrical performance of the final product. During this process, the press pad/cushion pad plays an indispensable role, as it not only affects the uniform distribution of pressure and temperature but also directly influences the flatness and interlayer bonding strength of the PCB.

Protective film is a crucial material in industries such as electronic manufacturing, display panels, and new energy. There are significant differences in performance, application scenarios, and durability among different types of protective films. PI (polyimide) protective film and PET (polyester) protective film are currently the two most common polymer materials on the market, each with unique advantages and limitations. In different industrial applications, the selection of materials depends on key properties such as high temperature resistance, electrical insulation, mechanical strength, chemical resistance, and transparency. The following is the main performance comparison between PI protective film and PET protective film:

The rapid development of the new energy industry has led to the continuous expansion of the application of PI protective films in fields such as lithium batteries, super capacitors, and photovoltaic modules. Its high temperature stability, excellent electrical insulation, and chemical corrosion resistance make it the core protective material for new energy products

In modern industrial manufacturing, the selection of materials plays a crucial role in product performance and reliability. PI (Polyimide) protective film is widely used in multiple high-tech industries due to its excellent high temperature resistance, insulation, chemical corrosion resistance, and high mechanical strength. PI protective film plays an irreplaceable role in fields such as PCB, LCD,etc.

With the development of high-tech industries such as electronics, semiconductors, and new energy, the performance requirements for materials are increasing. PI protective film has become an indispensable key material in various industries due to its excellent high-temperature resistance, insulation, and wear resistance characteristics. PI protective film can not only work stably in extreme environments, but also provide effective protection for electronic components, flexible circuit boards (FPC), display panels, etc. One of the biggest features of PI protective film is its excellent high-temperature resistance, which makes it irreplaceable in high-temperature manufacturing environments. Ordinary plastic materials are prone to deformation or degradation in high temperature environments, while PI materials can work stably for a long time at high temperatures ranging from 200 ℃ to 300 ℃, and even withstand higher temperatures (up to 400 ℃ or above) in a short period of time.

High temperature release film, as an important auxiliary material, plays a crucial role in many industrial fields, especially in composite materials, automotive, aerospace, and electronic manufacturing industries. These film materials not only need to have excellent high temperature resistance and release properties, but also meet various requirements such as high efficiency, environmental protection, and economy. With the continuous development of the global manufacturing industry and the increasing demand for high-performance composite materials, how to improve the performance of high-temperature release films and expand their application scope has become a focus of attention for the industry and researchers.

High temperature release film plays an important role in modern manufacturing, especially in composite materials and high-temperature curing processes. As a demolding and protective material, it is widely used in various fields such as aerospace, automotive manufacturing, and wind power generation. However, the use of resins and solvents poses significant chemical resistance challenges to high-temperature release films. In high-temperature environments, many resins and solvents have strong corrosives and high viscosity. If high-temperature release films cannot effectively resist the erosion of these chemicals, it will not only affect the demolding effect, but may also lead to film damage or performance degradation. High temperature release film is commonly used for demolding protection during high-temperature curing processes. Its main function is to prevent resin from adhering to molds or other surfaces, thereby ensuring smooth demolding of composite materials and other products. During this process, the high-temperature release film not only needs to withstand high temperature environments, but also must have the ability to resist resin and solvent erosion. To meet these requirements, the selection of high-temperature release films is usually based on the chemical stability, thermal stability, and solvent resistance of their materials.

High-temperature release film, as an important auxiliary material, plays a crucial role in many industrial applications, especially in the fields of composite material molding, automobile manufacturing, aerospace, and electronic equipment production. Its main function is to prevent resin, glue, and other materials from adhering to the mold surface, ensuring smooth releasing. The high-temperature resistance of release film is one of the key factors for its successful application in many high-temperature processes. Different types of high-temperature release films have different temperature limits. So, what is the maximum temperature that the release film can withstand?

The aerospace industry is a field that demands extremely high material performance, especially in the use of composite materials, which must meet stringent quality and technical standards. In the design and manufacturing process of aerospace vehicles, the application of composite materials is becoming increasingly widespread, especially in key parts such as air frames, wings, and engine components. High-temperature release film, as a thin film material that can effectively prevent substance adhesion in high-temperature environments, plays a crucial role in the aerospace industry.

In modern manufacturing, especially in fields demanding high precision and performance such as composite materials, aerospace, automotive, and electronics, high-temperature release films play a crucial role as key auxiliary materials. Their primary function is to prevent adhesion between molds and substrates during high-temperature curing, ensuring that the final product has a smooth and flawless surface. Therefore, selecting the appropriate high-temperature release film becomes a key aspect in enhancing production efficiency and product quality.

With the continuous advancement of industrial technology and the increasing complexity of manufacturing processes, protection solutions in high-temperature environments are also undergoing constant innovation. High-temperature buffer pads, as key protective materials, are widely used in many industries, such as electronics manufacturing, aerospace, automotive manufacturing, and metal processing. Although traditional buffer pads have been able to meet most of the needs in high-temperature environments, with the gradual escalation of working conditions, the industry's requirements for material performance are constantly increasing. To adapt to increasingly demanding high-temperature process conditions, more and more innovative materials have emerged.
