Hi experts,

I want to know the thickness of the red wiring in the figure below.

Is it okay to wire the same thickness as the MSP Tx (or Rx) signal line?

Best regards,

Hello Sasaki-san,

The connecting traces between diamonds should be as small as possible, typically 5mil (0.127mm), but please check with you PCB manufacturer to see what there minimum trace specification. See the attached for additional details. By chance, are you using the OpenSCAD scripts to generate the diamond patterns as described in SLAA891, Automating sensor designs using OpenSCAD? If so, I have attached a newer version of the trackpad script.

Hi Dennis-san,

Thanks for your information.
I don't know if the customer is using OpenSCAD. We will contact the customer with all the information you receive. Thank you as always.

Best regards,
Sasaki
