[0002] In the circuit board processing process, especially in the manufacturing of double-sided or multi-layer circuit boards, it is usually necessary to turn over the circuit board to realize double-sided processing. The traditional manual turnover method not only has low efficiency, but also is prone to damage to the circuit board or inaccurate positioning due to improper operation, affecting the processing quality. In addition, with the development of fine electronic products, the size and thickness of circuit boards are diversified, and the traditional fixing device cannot meet the needs of multi-size compatibility. Therefore, there is an urgent need for a circuit board processing tool with a turnover structure to realize efficient, accurate and safe circuit board processing.

The upper clamp plate and the lower clamp plate of the spring clamp are gently pried open, and one side of the circuit board is placed on the lower clamp plate. The reset spring and the upper clamp plate clamp the one side of the circuit board together. The tightness of the fastening bolt can be adjusted, and the sliding block can be freely slid along the sliding slot. The other side of the circuit board is placed on the spring clamp of the second clamping assembly, and the fastening bolt is loosened. The circuit board is turned over along the first rotating rod. After the turnover is completed, the fastening bolt is tightened to re-fix the circuit board. The circuit board can also be stopped at any angle and the fastening bolt is tightened to meet the needs of multi-angle adjustment.

[0004] The above-mentioned patent has the following disadvantages: the circuit board needs to be quickly cooled in each process. If the temperature is high during the circuit board processing, thermal shock may occur, which may damage the circuit board and components, and the processing quality cannot be guaranteed.
