G17a. Insert and solder U9 as in step G15a.
G18a. Insert and solder U10 as in step G15a.
Soldering the remaining pins for U7, U8, U9 and U10 may be done either as a
single operation or at any other pace preferred by you to ensure careful work
(no missed pins, no solder bridges). As you complete the soldering of each IC,
mark its respective assembly step.
G15b. 14 pins soldered on U7.
G16b. 14 pins soldered on U8.
G17b. 14 pins soldered on U9.
G18b. 14 pins soldered on U10.
