I would like to know what is the proper footprint for a 0603 Chip LED. I found this on PCB Libraries' website:  So where is Toe measured from? Heel? And what is Least Density? What is Courtyard?

The proper footprint for every surface mount package is derived from the IPC-7351 mathematical model. Did you download and install the Free Library Expert Pro. No license required and it supports 25 CAD tools and 3D STEP. https://www.pcblibraries.com/LibraryExpert/Pro/" rel="nofollow - https://www.pcblibraries.com/LibraryExpert/Pro/ - V2019.07 Just enter the package dimensions and tolerances to calculate the perfect 0603 footprint. ------------- Stay connected - follow us! https://twitter.com/PCBLibraries" rel="nofollow - X - http://www.linkedin.com/company/pcb-libraries-inc-/" rel="nofollow - LinkedIn |

Thank you, I have done so, it is very helpful. It would be nice to have a dimension tool for the generated footprint view. |
