"CPU scrap board" typically refers to the circuit boards or electronic components that come from discarded or obsolete computer central processing units (CPUs) and related electronic devices. These boards contain various materials, including metals, plastics, and small electronic components. Here are some key points about CPU scrap boards: Composition: CPU scrap boards are composed of a substrate, often made of fiberglass or other materials, on which electronic components are mounted. These components include microprocessors, memory chips, resistors, capacitors, and other integrated circuits. Metals Content: The boards may contain valuable metals, such as gold, silver, copper, and palladium. These metals are often used in the manufacturing of electronic components for their electrical conductivity and corrosion resistance. Recovery of Precious Metals: Recycling CPU scrap boards is a common practice to recover precious metals. Precious metal reclamation is typically done through processes like mechanical separation, chemical leaching, and refining. Environmental Considerations: Recycling CPU scrap boards is important for environmental reasons. It helps reduce electronic waste (e-waste) and minimizes the environmental impact associated with the disposal of electronic components. Economic Value: The recycling of CPU scrap boards can have economic benefits due to the recovery of precious metals. The value of the scrap depends on the market prices of the metals at the time of recycling. Processing Methods: Various methods are used to process CPU scrap boards for recycling, including manual dismantling, mechanical shredding, and chemical processes to extract metals. Regulations: There are regulations and guidelines in many regions regarding the proper disposal and recycling of electronic waste, including CPU scrap boards. It's important to adhere to these regulations to ensure environmentally responsible practices.

LP900 is a silicon carbide ceramic heat sink and it belongs to the micro-hole structure. Under the same unit area,it can be more than 30% porosity, greatly increasing the heat transfer area with air to enhance its cooling effect. At the same time its heat capacity is small, its heat storage is small and the heat can be more quickly to the outside world. Ceramic heat sink main features: environmental protection, insulation resistance to high pressure, efficient heat, to avoid brewing EMI problems. So it can effectively solve the electronic and home appliance industry thermal and cooling problems, while it is specially for small and medium wattage power consumption, design space pay attention to light, thin, short, small products. Whats more, it can provide technical support and application for electronic products innovative and development. For more , please kindly feel free to contact
