I have designed a circuit with a voltage regulator(ADP7156) from Analog Devices in KiCad. I have chosen the package type as 8-lead SOIC since I am planning to hand solder it to the PCB. While creating the footprint, I found the dimension of datasheet a little confusing.
From the picture, I figured out basic footprint as follows(drew in paint for clarification purpose)
X=0.41mm,
Y=1.05mm (=(6-3.9)/2 mm), here 6 is median ,
C=4.95mm (=Y+3.9),
E=1.27mm
2.29mmX2.29mm for exposed pad
Am I good to go draw the footprint in KiCad Footprint editor with these information I collected from Data Sheet. I usually find the recommended pcb layout on other manufacturer's datasheet which helped a lot to draw the footprint easily. Please guide me.
