Assuming the IC is a soic package with 0.050 pin spacing I measure the larger traces to be around 12 mil. This is the same number I get if I assume the three square pads below the ic and slightly left mount a preset with 0.2" x 0.4" spacing. All guesses.

Could you let us know the pin spacing of the ic used so that we have a scale.

Thanks
