TMS320C6678: EVM heatsink removal

Stellar Respree

Part Number: TMS320C6678

Hi,

I have TMS320C6678EVM and want to remove heat sink to replace to lower heat sink, but it seems like heat sink is glued with DSP chip.

Is there any safe way to remove heat sink from DSP ?

Regards,

Hi Stellar,

I've forwarded this to the design team. Their feedback should be posted here.

Hi Stellar,

Is the heat sink mounted on the board with screws, like in the bellow picture:

If this is the case, then there is most likely just a thermal compound between the SoC and the heat sink, so try to slightly twist it.

I've also notified the hardware team to elaborate on this.

Best Regards,

Stellar,

As Yordan mentioned in the above post, the heatsink is screwed up on the EVM. You need to remove the screws and pull the heatsink by slightly twisting it. If it sticks hard on the DSP, you may need to run some process to heat up the DSP. This would melt the glue/thermal paste and you can easily pull the heatsink.
