Introdução à pasta condutora
Conductive paste is a crucial electronic material composed of silver powder, solvents and additives. Its outstanding conductivity, flexibility and environmental-friendly characteristics make it an indispensable functional paste in modern industry. The content and quality of silver powder directly determine the conductivity of the paste, ensuring its efficiency and low loss in transmitting electrical energy, and providing stable and reliable conductive paths for electronic Dispositivos . Com sua ampla adaptabilidade a vários substratos, a pasta condutora pode ser aplicada a diferentes superfícies, como metais, cerâmica, vidro, plásticos, etc. ., cobrindo uma ampla gama de campos e usados (equipamentos médicos 3C, sistemas médicos, sistemas de veículos, aeroespacial e equipamentos de automação e etc.)
Situação atual da indústria de pasta condutora
Conductive pastes have a wide range of applications and the industry exhibits the characteristic of "overall dispersion and local concentration". The leading enterprises in each specific field have a relatively high market share. In the early days, the conductive paste market was mainly monopolized by international companies such as DuPont of the United States. Since 2010, with the rapid rise of China's electronic and electrical Indústria, várias empresas domésticas tecnicamente fortes aproveitaram profundamente as oportunidades de mercado e desenvolveram com sucesso vários novos produtos de alto desempenho, substituindo efetivamente os produtos importados .
Tendência da indústria de pasta condutora
The downstream application fields of conductive pastes are quite extensive. The conductive paste products are mainly used in 3C electronics (computers, mobile phones, etc.), medical fields, automotive industries, etc. In the computer field, conductive pastes can be used for conductive printing of keyboard membrane switch circuits, high-frequency circuitos de placas -mãe e placas gráficas, caminhos condutores de módulos de fonte de alimentação GPU/CPU, etc. .
In 2023, due to the global economic downturn, the shipment of personal computers declined. In 2024, as the inventory situation improved and new products were launched, the industry gradually recovered. In the mobile phone sector, conductive pastes can be used for the printing of flexible touch sensors for touch screens, edge electrodes of the screen, coating of battery electrode collectors, 5G Antenas de ondas milimétricas, bobinas NFC, circuitos de micro-switch e camadas condutivas de contato de botões .
In 2023, due to the global economic downturn, the shipment of smartphones declined. In 2024, with the improvement of inventory conditions and the launch of new products, the industry gradually recovered. In the medical field, conductive pastes can be used in glucose test strips, electrocardiogram patches, and neural electrode arrays, etc.
Com a melhoria dos padrões de vida das pessoas e a aceleração do envelhecimento da população, as pessoas se tornaram cada vez mais preocupadas com os cuidados médicos, o que é conducente ao crescimento estável da indústria de equipamentos médicos . no campo de touch e pasta de retrosco de retrosco, os quedos de retos com os pontos de retross de veículos, os campos de retos com retross de veículos, os quedos de câmeras, os painéis de backlumin em circuitos de retross. Antenas ocultas dentro do vidro da janela do veículo, etc .
Overall, the downstream market of conductive pastes is showing a trend of recovery or growth. In the future, with the construction of 5G base stations, the growth of the new energy vehicle industry, and the popularization of IoT devices, the demand for conductive pastes will continue to rise. As the application scenarios expand, the requirements for conductivity, thermal conductivity, and stability will be comprehensively enhanced, and the demand Para produtos de pasta condutiva de alto desempenho, continuará aumentando . De acordo com a previsão da Qyresearch, as vendas globais de pastas condutivas terão uma taxa de crescimento anual composta de 4 . 1% de 2025 a 2031, mantendo o crescimento contínuo.
