Hi,

I am about to make a foot print for an LCD but wanted to check first.

for connecting the 16 pins, correct me if I am wrong but the hole size is 1mm and the pad size is 2.54mm or less? and the spacing between each pad center is 38.1/16=2.38???

While I am at it, what does PTH stand for?

I know its simple but just want to double check.

Cheers

PTH = plated through hole
Pad width is 1.8 mm
Hole size is as you say, 1.0 mm ( a standard 0.025" square pin fits nicely)
Pitch between holes is 2.54 mm

This:

Means 15 spaces (for 16 pins) = 38.1 mm

It is also important, when the spacing is that close, to have the solder mask on the edges of the copper, to avoid bridging. Solder bridges reduce the production yield.
