AWR1843AOPEVM: EVM Heat Sink / Epoxy

Ryan T

Part Number: AWR1843AOPEVM

Hi Team--

Customer is reaching out about building their own board. They have the altium files for the AOPEVM and the BOM--they are trying to put it in a small package and on the BOM is listed H1 Heat Sink.

The dimensions for this heat sink are listed on the spec sheet, but is this device available for purchase? Can you guide me where I may be able to find it?

Additionally, the customer would like to know if there is any issue with having Epoxy covering this chip and board for a sealed product?

Thank you!

Hello Ryan,

Heatsink dimensions are provided in the EVM user guide shown below. https://www.ti.com/lit/ug/spruix8/spruix8.pdf

Heatsink are custom made with our contract manufacturing house, they are not available for purchase outside of the EVM.

If you are interested purchasing from our contract manufacturing house & custom heatsink design if needed, we could connect them with with the customer.

Also you could refer below appnote

Epoxy covering the chip is not recommended as it would affect the Antenna radiation pattern.

You could refer to below appnote mmWave Radar Radome Design Guide
