1. The keyboard is too big for most PCB holders. To keep the components flat as
you insert them, I suggest taping the keyboard PCB to the edge of your bench,
and install two rows at a time.

1. Using a lead-bender will help speed up the process and can help produce a
neater result. However, neatness is not critical, as the diodes will be
mostly hidden.

1. Check that the diodes are all facing the same (correct) direction.

1. Once the diodes are inserted, I suggest using a piece of painters tape to
keep then in place when you flip over the board for soldering.

1. After installing the diodes, install all the through-hole resistors.

1. Finally, flip over the PCB and install the 40-pin connector on the back side
(opposite side from the diodes and resistors).

1. It's important that the connector is seated flat to the PCB. To ensure a
properly seated connector, first tack pins on opposite corners of the
connector. Then, applying heat to one tacked pin, press the connector flat
onto the PCB. You will feel a small "snap" as the connector seats. Repeat for
the other tacked pin.
