Do you see the blue dots in the dimensions? Only enter any 2 of 3 that you want and never enter all 3. You'll get bad results due to over calculation of tolerances. |

Ahh..yes, I missed it.
It got worked now..  .In the component data sheet by the mafr the pads values are : L=5.5, W=1.2+-0.3, P=6.7 . is this values are based on nominal or most or least? and the generated footprints measurement were : Most Nominal Least L=6.83 L=6.46 L=6.12 W=2.7 W=2.52 W=2.31 other dimensions like outline and courtyards also varies, i didt checked. here I got the width of the pads entirely wrong it seems? and its a bit confusing which footprint (n,m,l) to use , in the internet most people suggests to use nominal footprints. Actually what is the best practice to follow?

Most people use Nominal Density Level, which is a default setting. Maximum Density is used for space satellites. Least Density Level is used for RF design or extremely dense designs. |

The solder joint goals in LE Lite are in the tab Terminal > Density Level > Toe, Heel and Side. You can control the entire solder joint by adjusting those values. |
