Maximum trace width for a CapSense trackpad and buttons

[user_1096206]

Hi, I am designing a small trackpad with some buttons to be used on wearable technology using CapSense. I followed the design guidelines described in AN64846 "Getting Started with CapSense" (https://www.cypress.com/file/41076/download ) that specifies a trace width no greater than 7 mil (0.18 mm).

I was wondering if a 0.2 mm width (in traces and hatch ground) is still acceptable to be handled with CYBLE-022001, because most of PCB manufacturers in my region cant handle a lower width.

Hi

0.2mm is acceptable for the design. It shouldn't cause any problems in design.

Thanks and regards
