heatsink for Arty Z7-20

[fgenolini]

Hi,

 

does digilent sell a heatsink for the Arty Z7-20 similar to the heatsink found on the Nexys Video Artix-7?

The Digilent heatsink is 35 x 35 mm, but the Zynq on the Arty Z7 is 17 x 17 mm

Regards,

Hi,

maybe of interest, here is a similar question:

Hi,

Thanks for pointing out this other interesting discussion topic.

I have seen a few 17 x 17 mm non-Digilent heatsinks (including some with fans) and double sided adhesive thermal pads

I was specifically curious to learn if Digilent had a recommended supplier and part number.

Hi @fgenolini,

We reached out to our engineering service manager. They responded the"  You will need to evaluate but this should work.  If not the dimensions of the current part are 19x19x13mm (actual 18.8x18.7x12.7mm). https://www.digikey.com/product-detail/en/cts-thermal-management-products/APF19-19-10CB-A01/294-1148-ND/1278274 ."

thank you,

Jon

A word of caution if you plan on using a arduino/chipkit shield with the heatsink attached to the Arty's zynq.

The heatsink in the link has a height of 9.5 mm from its base. The zynq height is 1.5 mm. When mounted to the zynq, the top of the heatsink would be 11 mm from the pcb (plus a small amount for the thermal tape thickness).

The arduino/chipkit headers are 8.5 mm tall.

Consequently, there is potential for interference between the heatsink and a shield plugged into the headers. This depends on the shield and if there are any components mounted on the bottom of the shield or if there are thru-hole connections.

As an example, the first picture shows a MTDS shield plugged into the Arty-Z7. The caliper shows board to board clearance is just over 11 mm.

The second picture shows a 9.8 mm heatsink sandwiched between the Arty's Zynq and MTDS Shield. You can see the potential for interference with the bottom mounted surface mount components.

thanks ?

I plan to use a ribbon / breakout board to signal lines, no actual shield, so I have some head room
