Problems solved by technology

The automation cost of this module integration method is high: because the space loss caused by the integration of each unit is large, in the final packaging, two substrates are required to package the module, resulting in increased costs and increased product weight.
At the same time, it is relatively difficult to design for high voltage and low current
