The application of synthetic stone materials in wave soldering is mainly reflected in the following aspects:
-Manufacturing furnace trays and fixtures: Synthetic stone has excellent high temperature resistance and can maintain dimensional stability in the high-temperature environment of wave soldering. It can withstand short-term high temperatures of 350 ℃ and continuous high temperatures of 260 ℃ without softening, deformation, warping, or other problems. It provides a stable and reliable load-bearing and positioning platform for PCB boards, ensuring the flatness and positional accuracy of PCB boards during the welding process
-Preventing short circuits and pollution: Its good insulation performance can avoid the risk of short circuits when in contact with metals in high temperature environments, protecting PCB boards from interference. At the same time, it can also prevent contamination of the gold fingers or contact holes due to human touch, which helps improve welding quality and product reliability
-Ensure uniform heat distribution: The low-temperature conductivity of synthetic stone can ensure good heat distribution on the substrate, making the PCB board more evenly heated during preheating and welding processes, which helps reduce welding defects caused by uneven heat, such as virtual soldering, solder leakage, etc
-Precision processing: Synthetic stone has good mechanical processing performance and can be accurately processed into various specifications of furnace trays and fixtures according to different PCB board size and shape requirements, meeting personalized production needs, ensuring the matching degree between fixtures and PCB boards, and further improving welding accuracy
-Chemical corrosion resistance: It has good corrosion resistance to chemical substances such as acid, alkali, and salt, and can resist the erosion of chemical substances such as soldering flux, ensuring the service life and reliability of fixtures and reducing production costs
-Anti static protection: During the electronic manufacturing process, static electricity may cause damage to electronic components. Synthetic stone has anti-static properties, which can effectively prevent static electricity from affecting electronic components on PCB boards and ensure product quality
