I have a project which contains an IC that requires 2 guard traces between some of the pins. Since the ICs Pin pitch is 0.65mm/25.6mil this would require the usage of trace spacing/width smaller than 3mil to work with. When using the recommended pad size for the IC a trace spacing/width of 1.6mil would be required.
Reducing the Pad size to 0.4mm instead of 0.45mm would bring the required spacing/width to 2mil. The component leg width, as given by the manufacturer can be up to 0.3mm, therefore the pads need to be at least as wide as this, bringing 3mil spacing/width out of the question.
