. IPC considers that both round and rectangle leadsare the same, but PCB Libraries, Inc. believes that the round terminal leadconsumes more volume in the hole than a rectangle lead and therefore the holeover round lead should be larger than hole over rectangle lead

0.8 mm dia lead with a standard bend form (as opposed to a welded bend) component, per IPC. To calculate the lead bend extension from the end of the part, you need to add the other parts of the calculation which are the value of the minimum bend radius (R
