The following diagrams describe the recommended mounting structure:

─ Thermal interface material between MCPCB and Heat Sink

─ Plastic washers between M3 or #4-40 screw heads and MCPCB.

Please note that the following diagrams use one of our MCPCB product as a general depiction of

the mounting structure. Refer to “Dimensional Drawing” section in this datasheet for the exact form

factor of the product in this datasheet.

Thermal interface material

A good thermal design requires an efficient heat transfer from the MCPCB to the heat sink. In order

to minimize air gaps in between the MCPCB and the heat sink, it is common practice to use thermal

interface materials such as thermal pastes, thermal pads, phase change materials and thermal

epoxies. Each material has its pros and cons depending on the design. Thermal interface materials

are most efficient when the mating surfaces of the MCPCB and the heat sink are flat and smooth.

Rough and uneven surfaces may cause gaps with higher thermal resistances, increasing the overall

thermal resistance of this interface. It is critical that the thermal resistance of the interface is low,

allowing for an efficient heat transfer to the heat sink and keeping MCPCB temperatures low.
