  • Hi Shimon,

    Try:

    symbol = car(axlSelectByName("REFDES" "U40")); Select the BGA
    axlClearSelSet()
    pins = symbol ->pins; Identify the BGA pins
    minPitch = nil; Declare the minimum pitch variable
    foreach(pin1, pins
    foreach(pin2, remove(pin1, pins)
    pitch = axlDistance(pin1 ->xy, pin2 ->xy); Measure the pin to pin pitch of every pin with every other pin
    minPitch = if(minPitch, min(minPitch, pitch), pitch); Compare pitch with minimum found so far.
    )
    )
    minPitch

    Cheers, Dave
