Version 26.08 was just released!!

Fixes & Enhancements:

  • Library Editor:
    • When having 2 sessions of Footprint Expert running
      • Copying an FPX file row from one session to another session overwrites an existing row
  • FP Designer:
    • When switching between Assembly Polarity Marking in the Drafting Options, the 'None' option wasn't working
    • Updated the Pad Stack Manager for Thermal Pad Paste Mask 
      • Not showing the true coverage %
      • Not turning on the 'Update Pad Stack' button when a value was changed
  • Calculators:
    • Molded Body - The 'D1' dimension was removed and is now calculated to be 0.40 mm less than 'D'
      • This now allows the terminal lead to be flat against the package body
    • When the Mirror feature is used, a warning symbol will appear in the upper left corner of the viewer
    • Molded Body Thyristor not opening in viewer because the polarity was non-polarized and should have been polarized
  • Options:
    • Drafting > Courtyard - added a new option to map the courtyard outline to the Nominal Body
      • Note: the default setting is Map Courtyard to Maximum Body
  • CAD Tool Interfaces:
    • KiCad - Added rounded corners for thermal tab paste and solder mask pattern shapes

V26.08 pre-release has a new Molded Body Calculator. 

The D1 dimension was removed because 80% of component manufacturers do not provide it. Now you can build any version of 15 component families in the Molded Body calculator. 

Please check the latest pre-release and let us know if you like it.

Here is the new 3D STEP Model:

I discussed this issue with the programmer and the through-hole SIP E1 dimension was swapped because in V25 a positive value moved the row down and a negative value moved the pins up. 

This didn't make logical sense and was updated so a positive E1 offset moved the pins up and a negative value moves the pins down. 

Sorry for the update, but the original release was incorrect and fixed in V26.

The direction of the offset was flipped between 2025.04 and 2026.08. The same FPX gives different footprints. I was wondering when it happened.

The E1 dimension is for the 'Offset' from the center. 

If the pins are centered, do not enter a E1 dimension as it's Optional. 

There is no SIP 'Mirror' feature in the current V26.07 release.

When did the direction of the E1 offset on SIP packages get flipped? 

It bit me on a new design, where a regenerated footprint had a mirrored layout. 

I think the new way is OK, I was just surprised.

Update: we're working on updating the Molded Body calculator to allow 2 lead forms in a drop-down menu. 
  1. Inward Flat Ribbon L-Lead
  2. Right Angle Lead
This update would effectively eliminate the 'D1' dimension because most Molded Body packages with Right Angle terminal leads do not provide the 'D1' dimension in their datasheets. 

This update will not affect any footprints because they are all based on the 'D' dimension. 

The 'D1' dimension only affects the 3D STEP model but, in the future, the 'D1' dimension will be determined by which lead form the user selects.
