In this context, brick-type power supply modules are also continually shrinking all the way from full brick, half brick, 1/4 brick, 1/8 brick, 1/16 brick. The reduction in volume significantly affects various aspects of the design and application of the power module, heat dissipation being an important point. Structurally, the brick-type power supply circuit board is attached to the aluminum substrate, then the aluminum substrate is filled into the plastic shell, heat-conducting glue is filled into the cavity through the small holes, and after the pouring sealant flows, the whole inner circuit board is covered to form a brick-type. As shown in fig. 1, the brick-type power module a is not used alone, and needs to be soldered onto the PCB board C, and other devices B are also mounted on the PCB board C.

In the case of the heat conducting pad, the thicker the heat conducting pad is, the larger the thermal coefficient is, and when the gap between the power module and the heat conducting component is larger, the heat dissipation is adversely affected by the thicker heat conducting pad.
