What are the thickness requirements for circuit board heat sinks for high-speed stamping?

  High-speed stamping on the thickness of the circuit board heat sink has certain requirements, mainly in the following aspects:
First, stampability aspects
    Minimum thickness limit
        High-speed stamping usually has a lower limit on the thickness of the heat sink requirements. If the thickness is too thin, the material may be unstable in the stamping process, such as wrinkling, rupture, etc.. This is because a material that is too thin has difficulty maintaining sufficient strength and stiffness under the powerful impact of high-speed stamping.

    Maximum Thickness Limits
        The thickness of heat sinks should not be too great, or the efficiency and quality of high-speed stamping will be affected. Thicker material requires greater stamping pressure, which may be beyond the capabilities of a high-speed press or lead to increased wear and shorter equipment life.
        In addition, excessively thick heat sinks may suffer from uneven deformation and difficulty in controlling dimensional accuracy during the stamping process.
Second, the impact of performance

    Heat dissipation performance
        The thickness of the heat sink will directly affect its thermal performance. Generally speaking, thinner heatsinks have lower thermal resistance and relatively higher heat dissipation efficiency. However, too thin heatsink may be insufficient strength, easy to deform, affecting its contact with the circuit board and heat dissipation effect.
    Electrical Performance
        The thickness of the heatsink may also have an impact on the electrical performance of the board. If the heatsink is too close to the electronic components on the board, an excessively thick heatsink may cause problems such as electromagnetic interference.
