Pay attention to the position : the upper surface must be at 8mm
(0,3 inch) above the pcb surface (see drawing 2.0).
You may put some pieces of paper between the LCD and the pcb, to
help you holding the display on the right height.
First solder only the pins at the four corners.
Verify the height, and correct if necessary.
Then solder the remaining pins.
Be very careful, for this part is not cheap!
