hi,
While creating the foot print, Mr.Robert uses some reference values in the Orcad course. for example, while creating the footprint for SMD capacitor 1210, he uses the following values.
Terminal pin spacing (e1) = 3.1mm
Package width (E) = 4.9mm
Package length (D)=3.3mm
As per the datasheet, the package width (E) is 2.8mm and package length (D) is 2.6mm.
1. May I know how Mr.Robert calculating the values for the components ( like do we have any reference procedures like add 0.1 or 0.5 mm to the values specified in the datasheet) ?
2. How to calculate the value for terminal pin spacing (e1) ? (is it distance between two pins?. i am getting e1 value as 1.85mm for the 1210 smd capacitor)
Thanking you.
Thanks & regards,
Rajasekaran
