High temperature nano composite material (synthetic stone) is a new type of material introduced by our company, which is also called synthetic stone or reinforced fiber plastic abroad. High temperature nanocomposites are glass fiber compounds, which are mainly designed for the different needs of the PCB mounting process.
High temperature nanocomposites (synthetic stones) have the ability to continue to maintain their physical properties in an environment with gradually rising temperatures, so that they can achieve high standard results without deformation in the wave soldering process. In the harsh environment of 350 ℃ for a short time and 280 ℃ for a long time, the high temperature nanocomposite (synthetic stone) will not be separated. As a result, high-temperature nanocomposites (synthetic stone) can improve the quality of PCBA in the wave soldering process and avoid contamination of gold fingers or contact holes due to human touch.
　　High temperature nanocomposites (synthetic stone) have been proved to be suitable for various processes in wave soldering and SMT installation. It can be machined to the accuracy required by the STM process, and maintain its flatness in the continuous wave soldering and reflow soldering cycles. The low thermal conductivity of high-temperature nanocomposites (synthetic stones) can prevent the deformation of the substrate, so as to ensure the PCBA welding quality.
characteristic:
　• High temperature nanocomposites (synthetic stone) have excellent physical properties at rising temperatures;
　• The dimensional stability and flatness can still be maintained after repeated substrate installation;
　• Low thermal conductivity of high-temperature nanocomposites (synthetic stone) to ensure the heat distribution on the substrate;
　• The synthetic resin composition in the high-temperature nanocomposites (synthetic stone) can effectively block the active characteristics of the flux and prevent the production of tin tips;
　• By virtue of the characteristics of high-temperature nanocomposites (synthetic stone), the fixture mounted on the substrate can be used for precision machining.
