ASSEMBLY OF THE PCB
4.1
1mm Sockets For Nixie Tubes
There are 44 individual sockets that need to be soldered in. The
best method is a follows. Place all sockets into the holes, noting
that for each tube there is one hole that has no socket as show
below. When all sockets have been placed, place a flat and hard
object over the top of the sockets, and turn the PCB over so you
can solder from the underside. Be sure to insert the sockets FROM
the component side of the PCB – the side with the white
component markings. The photo below shows the component side
of the PCB after all the sockets have been inserted and soldered in.
4.2 Capacitor C7
Mount C7 on the same side of the PCB as the white cross-hatched
markings for Q1 and IC1. See below.
Clip the leads on the main component side very short, as the IC
socket for IC2 will need to fit over the trimmed leads.
