   I don't see a solder joint goals download anymore.  Is the methodology obsolete?

   Don't forget to change Through-hole too.  Preferences > Terminals > Through-hole > Pad Size Round-off.   | |

   Preferences > Terminals > Corner Concave > Settings > Pad Size Roundoff  As soon as you select another Terminal like "Cylindrical End Cap" you will get a notification:  Apply Setting Changes to all surface mount terminals? Yes or No | |

I do want to change the pad round off to be 0.05. Where would I do that globally? For all packages?

   IPC-J-STD-001 clearly states that the Toe solder joint goal should be a minimum of 25% of the Terminal Height or 0.50 mm, whichever is greater.  Look in the Tables.  | |

Hi Tom. What is to be considered the starting point for the toe? Lead length? Or landing pad length? Nominal, max?  I haven't been able to locate any documentation that indicates where this starting point is. I don't have a copy of the IPC-J-STD-001 yet. Hope to have that soon.  | |

   There is a Pas Size Round-off in the Preferences or the "Terminal > Settings" tab.  Change the Pad Size Round-off to 0.05 or whatever you want.  | |

   I like the new solder joint goals. What I don't like too much is that the pads don't calculate to even numbers.  | |
