AI Technical Summary

Technical Problem

In existing controller testing equipment, the load connection scheme results in a scattered layout and large space occupation. Furthermore, as the complexity of the controller under test increases, the PCB board size increases, which increases the cost and design complexity.

Method used

It adopts a double-layer printed circuit board structure, with the load resistor placed between the two boards. The power drive and digital signal pins of the controller are connected through wiring terminals. Combined with a cooling fan and support mechanism, it achieves three-dimensional integration and effective heat dissipation.

Benefits of technology

It saves space in the planar layout, reduces thermal interference, improves test stability and accuracy, and meets the needs of more complex test scenarios.
