Placement concerns

MacTuxLin

Hi,

May I check if the below placements will cause any potential problems? I'm not sure if the crystal placement will cause any problems? EMI?

Thanks a lot.

Updated image: Thanks to Batang, I now have a face to the prop.

Apart from the TQFP pins overlapping the pads at the edge of the board you mean?

So long as there's a ground plane I wouldn't worry, the crystal oscillator is low-power and low frequency, the EMI comes from the wires connected to the IO pins!

Thanks. I was thinking to utilize the batch of prop on-hand but still fit in a 50.8mm by 17.78mm package. Anyway, I'll switch to qfn.

Updated footprint. Looks neater now.

Hi MacTuxLin,

It looks like you are using Altium designer, is that is so then ctrl C will copy the image to the clipboard in a DPI you can choose.

Other than that the placement looks ok.

Cheers.

Thanks Batang. Yes, I'm using AD10. good tip. BTW, you are using AD9/10 as well? If so, how did you place those prop's silk-printing onto your 3D body?

MacTuxLin,

When using an extruded 3D shape you can apply a texture to the top of it.

See the included ApplyTexture.png, also included is the texture I created.

Note: The texture file does not embed in the 3D shape and if you move the location (folder) for the texture file it will not be visible until you update the new location.

Another tip you may know already, Shift S will toggle between all layers visible and single layer only, the use the * key to toggle between top and bottom layers and +- cycle all active (visible) layers.

Cheers.
