Screw 2 plastic 8 mm standoffs to the mounting holes of the backlight board. If you are planning to
put the nixie clock into the designated acrylic enclosure from Elektor, you should use two M3x16
machine screws and two nylon M3 washers to hold the standoffs in place. The M3x16 machine
screws should protrude from the standoffs. Please note that the M3x16 screws are part of the kit
for the enclosure, they are not included with the nixie clock kit.
If you are not going to use the enclosure, mount the spacers to the backlight board using two
M3x6 screws and two nylon M3 washers.
Attach the backlight PCB to the display PCB. Use 2 8 mm standoffs if you are going to use the
Elektor enclosure. These are included with the kit for the enclosure. Otherwise, use two M3x6
machine screws and two nylon M3 washers.
