Hello, 

   

I am working on a 24+2ends segmented slider, and would like to Diplex it. I am concerned about the Cp of the segments in a diplexed configuration. I am also curious about increasing the segment height to 20-24mm, so the user has a better chance of hitting the slider that will be hidden under a wood overlay(85mm wide) with no outside visual indication the slider is beneath. 

   

Device is PSOC 4000S - CY8C4024LQI-S412

   

My traces are 0.16mm wide and are an average of 120mm long total for each diplexed channel. 

   

Slider segments are 8mm wide and 15mm in height using H/4 rule for the dual chevron and .5mm spacing as per datasheet.

   

4 layer FR4 1.2mm thick

   

3m 468MP for adhesive

   

1.2mm wood overlay oil/wax finish.

   

 

   

Should I be concerned about what I am attempting to do? It looks like the 4000s series is able to accommodate 200pF of sensor capacitance each channel will surely fall in that range.
