[0027] With this structure, the DBC substrate can be cleaned in all directions, and the water on the DBC substrate after cleaning can also flow away quickly without remaining on the product surface, and it is easy to dry. The model of the intermediate frame can be set according to the size of the DBC substrate, so that this cleaning carrier can place DBC substrates of various specifications.

[0028] Furthermore, both the first profile plate 1 and the second profile plate 2 are hollow plates, which is convenient for the operator to observe the cleaning degree; the four corners of the first profile plate 1 and the four corners of the second profile plate 2 are fixedly connected by four connecting rods to form a square cavity. Multiple intermediate frames 3 are all square frames with open upper ends, and clamping grooves 8 are provided along the inner walls of the intermediate frames 3, and the DBC substrate can be inserted into the frame through the clamping grooves 8.

[0029] The connecting parts 4 are all damping hinge shafts, which are rotatable and angle-fixable rotating shafts, and can adjust and fix the relative angle between the intermediate frame 3 and the profile plate.

[0030] The intermediate frame 3 includes a first rod 5, a second rod 6 and a third rod. The first rod 5 and the second rod 6 are respectively vertically arranged at both ends of the third rod 7 to form a square frame with an open upper end. Clamping grooves 8 are provided on the inner walls of the first rod 5, the second rod 6 and the third rod 7 to insert the DBC substrate, and through holes are provided at the bottom of the third rod 7 for installing the connecting parts 4.
