IPC 7351A: Generic requirements for surface mount land pattern and design standard

Click here to give it a try! Enable Reverse Pin Order to reverse the pin order. If would like to speak with a representative, please contact your local Altium office.

Making things is awesome. Detailed descriptions of how to utilize attributes can be found through the online tutorials provided by PCB Matrix Corp.

The IPC Land Pattern Calculator is a shareware program that allows users to view IPC approved land pattern dimensional data in tabular form as well as graphical images that illustrate how a component is attached to the land pattern on the board.

The time now is The maximum heel spacing is calculated by adding the tolerance on the inner distance between the heels of the opposing rows of leads to the minimum heel spacing. Enter the required values for ipc-7351 tolerances on the Chip Component Component Tolerances page. I wont do it again: The SOT23 Footprint Dimensions page displays the inferred footprint dimensions using the package dimensions previously defined.
