I am interested in purchasing the EPC 9099 Development Board. The datasheet recommends using a heatsink and TIM (thermal interface material). Could you please confirm whether the heatsink and TIM are included with the board, or if I need to order them separately? Thanks
Welcome to the forum.
The data sheet is vague but my impression is that the heat sink/spreader is not included.
I haven’t the time to watch it, but this official training video may have the answer.

Thanks for reply. I watched that video but they did not mention any thing about heat sink.
If its not included with board .how I can buy the heat sink because there is no part number in BOM?
The data sheet mentions that the heat spreader is custom and they provide complete mechanical engineering details.
So I assume they expect you will source it from your usual metal fabricator for your prototypes. That way when build the 1,000 piece production run you have an approved vendor all setup.

Is it possible i can find heat sink on DIGIKEY for this board?

I don’t think so BUT I don’t work for DigiKey so I may be very wrong about that.
It’s very early at the DigiKey main location so it will be a few hours until the main engineering workforce is online to give a definitive answer.

Hi farhan.nasir, to my knowledge we don’t offer or facilitate custom heat sinks or heat spreaders as described in the manufacturer document. They describe several TIM options from various manufacturers on page 8 of the quick-start guide, but they expect that their customers will source the heat spreader from a fabricator, and do not provide an “out of the box” option for the heat sink/spreader.
What I recommend in this case is searching for a supplier that offers custom cuts of thermal material that could make something in line with the EPC specifications. I believe Wakefield-Vette offers customization options, if you got a part number from them we would be able to quote it as a non-catalog item, but it’s ultimately your decision whether you want to source directly from the supplier or attempt to generate a part number with them and quote it through us.

DigiKey does have suppliers that do custom cut heat sinks but that is usually limited to existing extrusion shapes our suppliers like Wakefield Vette and Advanced Thermal Solutions have, and those extrusions are something like below where they are just getting cut to a specific length and maybe four holes drilled in them.
The below shape is custom heat spreader plate, that is not something our suppliers would do as a one off. like @chris_groom indicated you’d just have a machine shop cut the below drawing out of aluminum or copper.
