In today's rapidly evolving electronic technology era, various types of electronic products are continuously advancing towards miniaturization and high performance. From the smartphones we carry with us daily to smart TVs in our homes, to precision instruments in industrial fields, the reliability of connections between electronic components and conductivity are crucial, and this is inseparable from a key material - anisotropic conductive film (ACF) adhesive.
ACF adhesive is typically a polymer bonding material composed of high molecular materials and conductive particles, akin to a magical "electronic tailor" that combines adhesion, conductivity, and insulation. Its most notable feature is vertical conduction and horizontal insulation. This unique performance allows it to excel in the electronics field, serving as a reliable assistant for connecting and fixing various electronic components and circuit boards. Whether it's compact electronic tags, smart cards, complex integrated circuits, display panels, or emerging wearable devices, smart homes, sensors, and more, ACF adhesive plays a silent yet crucial role.
In the electronic world, signal transmission is like a race, with conducting particles serving as the racetrack, and nickel conducting particles can be regarded as "high-speed tracks." Nickel has good electrical conductivity, with relatively low resistivity, providing a smooth "racetrack" for electrons to pass through quickly, ensuring efficient transmission of electronic signals and greatly reducing signal loss and delay. This makes ACF adhesives using nickel conducting particles excel in high-frequency and high-speed signal transmission scenarios. In products with stringent signal transmission requirements, such as smartphones and 5G base stations, it helps devices achieve faster data processing and transmission, allowing us to enjoy smooth electronic experiences without video buffering or gaming latency. Compared to other conducting particles, such as some non-metallic conducting particles, nickel conducting particles have a clear advantage in conductivity. Non-metallic conducting particles often have inherent deficiencies in conductivity, with larger resistance, making it easy for electrons to encounter obstacles when flowing through, similar to bumpy roads that cause rapid attenuation of signal strength, failing to meet the current needs for precise and high-speed operation of electronic products. With its stable and excellent conductivity, nickel ensures efficient transmission of electronic signals, firmly occupying the "C position" of conducting particles in ACF adhesives.
The usage environment of electronic devices is complex and changeable, ranging from hot and humid tropical rainforests to cold and dry polar regions, from daily office environments to dusty factory workshops, ACF glue needs to work stably. Nickel conductive particles have excellent stability. In harsh environments such as high temperature, high humidity, and acid-base, they can still maintain their posts and ensure that conductivity does not "drop out". In high-temperature environments, general metals may undergo structural changes due to thermal expansion and contraction, affecting conductivity, but nickel has a high melting point (1455°C) and good thermal stability, capable of withstanding the heat generated by the operation of electronic devices and maintaining stable conductivity pathways; in humid environments, the dense oxide film formed on the surface of nickel acts as a "shield", effectively resisting water vapor erosion, preventing rust short circuits, and ensuring reliable connections between electronic components. This stability greatly extends the service life of ACF glue, reducing the risk of electronic device failure due to material aging and laying a solid foundation for the long-term stable operation of electronic products. Whether it's drones working outdoors for extended periods or automotive electronics that need to withstand seasonal temperature differences, ACF glue containing nickel conductive particles can provide stable support.
In the "palm world" of smartphones, internal space is truly "inches of gold." From processors and storage chips to camera modules and displays, a multitude of components require tight and reliable connections. Nickel conductive particles contribute to the success of ACF adhesives, enabling more intricate and dense wiring between the phone motherboard and various chips, meeting the demand for ever-thinner, high-performance phones. For instance, in chip packaging, ACF adhesives with nickel conductive particles can connect tiny pitch (fine pitch) chips to substrates, allowing phones to integrate more functional modules within limited space. Features like high-pixel photography, 5G high-speed communication, and powerful graphics processing capabilities found in current flagship phones all rely on nickel conductive particles to ensure fast signal transmission. Moreover, even under daily use scenarios such as drops, vibrations, and temperature changes, it can still maintain stable circuit connections, keeping the phone "online" and avoiding crashes or display issues. Tablets follow the same principle; whether for large-screen entertainment, mobile office work, or graphic design creation, nickel conductive particle-powered ACF adhesives provide stable support for their complex internal circuitry, ensuring smooth operation experiences.
The screen serves as the "window" for interaction between electronic devices and humans, demanding exceptionally high standards in display performance. In the manufacturing of Liquid Crystal Display (LCD) and Organic Light-Emitting Diode (OLED) screens, ACF adhesive plays a crucial role in connecting components, with nickel conductive particles being the unsung heroes within it. Taking LCD screens as an example, their driver chips need to precisely control the opening and closing of each liquid crystal pixel to present clear and vivid images. The ACF adhesive containing nickel conductive particles is responsible for connecting the driver chip with the electrodes on the glass substrate. Due to the stability and conductivity of nickel conductive particles, it ensures that electrical signals are accurately transmitted to every pixel point, enabling rapid refreshment of the image and precise color reproduction, avoiding display flaws such as bright spots, dark spots, or ghosting. In OLED screens, organic materials are sensitive to the environment, highlighting the stability advantage of nickel conductive particles. They not only ensure good compatibility with organic layers under complex processes but also safeguard circuit connections during bending and rolling of flexible OLED screens, maintaining stable light emission control and delivering breathtaking visual experiences for consumers. Whether watching high-definition movies, playing competitive games, or engaging in professional design, they can enjoy lifelike and detailed images.
Nowadays, wearable devices such as smart bands, smart watches, and smart glasses are gradually integrating into people's lives. They pursue extreme lightweight, miniaturization, and flexibility, posing significant challenges for the materials connecting internal electronic components. Nickel conductive particles, with their unique properties, enable ACF (Anisotropic Conductive Film) adhesives to excel in the field of wearable devices. For instance, in a smart band with limited internal space, where battery, sensor, processor, and other components are tightly packed, the tiny size of nickel conductive particles can adapt to the fine line connection requirements. Even under daily usage deformation such as bending and stretching, it still ensures stable transmission of heart rate and sleep monitoring data, as well as smooth operation of functions like information push and exercise recording. Smart watches are no exception; they integrate more complex functions such as calling, mobile payment, health detection, etc. The ACF adhesive containing nickel conductive particles ensures reliable electrical connections between various functional modules. It can maintain stable operation even in sweaty or frequently colliding usage scenarios, laying the foundation for people to enjoy convenient intelligent life anytime and anywhere, truly realizing "seamless connection" between humans and technology.
With the rapid advancement of technology, the field of nickel conductive particles and ACF adhesives is experiencing wave after wave of technological revolution. Thanks to nanotechnology, the size accuracy of nickel conductive particles has been further improved, allowing precise control at the nanoscale level. This enables ACF adhesives to achieve more refined and uniform electrical connections at the microscopic level, paving the way for the packaging and connection of cutting-edge electronic components such as quantum chips and ultra-micro sensors in the future. For instance, quantum chips have extremely high requirements for signal transmission stability and precision. Nanoscale nickel conductive particles can achieve nearly lossless signal conduction between qubits with minimal contact resistance, fully unlocking the potential of quantum computing.
In the field of material composite innovation, researchers are committed to integrating nickel conductive particles with novel polymer materials. On one hand, they are developing ACF adhesives with higher heat resistance and flexibility to meet the usage requirements in extreme environments for aviation, aerospace, and automotive electronics industries.

Novel composite ACF adhesives can undertake this responsibility, ensuring flight safety. On the other hand, ACF adhesives with self-healing functions are also being developed. When materials suffer minor damage, internal special structures or added repair agents can automatically identify and repair, extending the service life of electronic devices. This has broad application prospects in satellite electronic equipment that is difficult to maintain over long periods, ensuring stable operation and continuous transmission of valuable data in the vast universe.
Although nickel-based conductive particles hold promise for the ACF adhesive industry, the road ahead is not without challenges. Firstly, the stability of raw material supply poses a significant concern. As an essential strategic resource, global nickel supply is greatly influenced by international political dynamics, mining progress, and resource nationalism. In recent years, policy fluctuations in some major nickel-producing regions have led to volatile nickel prices, directly affecting the production cost of nickel-based conductive particles and subsequently impacting the product price of ACF adhesives, exerting pressure on downstream electronics companies in managing costs. To address this predicament, enterprises need to take two key approaches: one is to diversify their procurement channels and establish long-term partnerships with suppliers from multiple producing regions to mitigate the risk associated with relying on a single source; the other is to increase investment in research and development of recycling technologies for nickel resources, extracting nickel from waste electronic products and industrial waste to build a circular economy model that ensures sustainable raw material supply.
Cost control is also a critical challenge that needs to be overcome. The market competition for electronic devices is fierce, with price wars rampant, and downstream customers are highly sensitive to the cost of ACF adhesive. The production of nickel conductive particles involves complex processes, from nickel ore smelting and purification to the manufacturing of conductive particles, which incurs significant costs in energy consumption, equipment investment, and labor expenses, resulting in a slow decline in the overall cost of ACF adhesive. Against this backdrop, industrial cluster development emerges as a solution to break the deadlock. Upstream and downstream enterprises gather in specific regions to share infrastructure and logistics resources, reducing production and transportation costs. At the same time, manufacturers optimize their production processes, introduce intelligent and automated equipment, enhance production efficiency, reduce labor costs, and ensure a gradual decrease in the prices of nickel conductive particles and ACF adhesive products while maintaining product quality, thereby enhancing market competitiveness.
