Footprint Generator: DIL Pads

Default units: (you may override this by adding "mil" or "mm" to your values below)


Pad Numbering Sequence

 A      B      C      D      E      F 
1 8    1 5    1 2    8 1    5 1    2 1
2 7    2 6    3 4    7 2    6 2    4 3
3 6    3 7    5 6    6 3    7 3    6 5
4 5    4 8    7 8    5 4    8 4    8 7
NP: (number of pads)
SEQ: (pad seq, see chart)
 

Enter whatever data you have, as long as it's sufficient to describe the footprint:

BL: (body length)
BW: (body width)
Draw physical outline too?
C: (clearance)
CW: (component width)
E: (pitch)
G: (gap)
LL: (lead length)
LW: (lead width)
M: (mask)
PG: (pad gap)
PL: (pad length)
PLC: (pad length, center-center)
PLE: (pad length extension)
PW: (pad width)
PWE: (pad width extension)
PXL: (pad extents length)
SO: (silk offset)
SOC: (silk offset to center)
SW: (silk width)

Note that M (mask) is the distance between the copper and the mask. It can be a percent, which is a percent of PG (pad gap) by appending % (example: 25% instead of 6mil). Likewise, C is the distance between the copper and any polygons, with a percent being a percent of PG. PWE and PLE can be percentages of LW and LL, respectively, and G can be a percent of BW.
