Problems solved by technology

[0004] Because in the semiconductor process, the gold wire 2 has a height, and the gold wire 2 needs to be accommodated between the optical lenses 1, and the installation space is reserved for the gold wire 2, especially in the height direction, so the optical lens 1 The distance H between the circuit board 5 and the circuit board 5 is difficult to reduce, resulting in that the height of the device cannot be effectively compressed, and it is difficult to realize thin, light and small products and space-optimized settings
