install. Grip one of the tabs with your needlenose pliers and bend it back
and forth until it comes off. Do the same for the other tab.
F13. Next take the 14 pin dual row connector and place the short side
pins through the LCD display board from the back. The back is the side
with the big IC on it and the front is the LCD side. Solder all 14 pins.
F14. Once the pins have cooled, place the LCD board through the holes
for the connector on the front panel. If you push the LCD board flat you’ll
see that the IC on the back of it is a good marker for height and flatness.
You’ll also see that J2 sits underneath the LCD board. With the board
pushed flat against the IC, take a look at the tab on the LCD that’s closest
to J2. Yes, it might be a little
too close! We’re going to bend that tab just to
be sure it doesn’t short to J2. Simply bend it gently away from J2 so that
when you solder the LCD board to the front panel board no part of that tab
is touching any of the pins of J2. Be careful when bending it because it’s
holding the LCD on and you don’t want to damage anything.
F15. Now you’re ready to solder the LCD board to the front panel board.
Hold the LCD board flat on the IC on the back and solder one of the cor-
ner pins, then check flatness before soldering the opposite corner pin.
Carefully solder the rest of the pins of the connector. Be careful handling
the board when you’re done; those pins stay hot for a little while!
F16. Look over your connected boards and make sure all the solder joints
look good, all parts are installed, the LCD is nice and flat and flush to the
board using the IC as a guide for flatness. Our next task is to connect the
main and front panel PC boards and once it’s done you won’t want to try
and get them apart again, so check the boards over carefully now, before
it’s too late. The flatness of the LCD board is especially important for the
kit to fit correctly into the case.
F17. We’ll make sure our boards are going to line up with the front panel
and case before we solder everything together (and it’s too late!). Take
the front panel board, one of the bezels (plastic case parts), and the bot-
tom base tray for your case. The front panel board sits inside the bezel
and the bezel is attached to the base tray using one of the included
screws. The front panel will only fit on one side of the bezel. Look at the
two screw holes on the front panel and you’ll see two screw holes to line
them up with on the bezel. Before screwing the parts into the base tray
you’ll want to peel the protective plastic from the front panel. Screw the
front panel into place on the base tray.
F18. Now take the front panel board and slide it into its place on the main
board. All the pins on J1 should line up with J2 and J4 should line up with
J5.
F19. Take the connected but not yet soldered boards and slide them into
