All parts should be assembled in correct order, starting from SMD components to low profile
components and finally to high profile ones. Component locations are not marked on PCB because a
"clean look" of the shield is very important. So, component (Part) locations are in the following image
and their values are in the above table.
Note: The assembly of this shield PCB implies that you have already successfully assembled the
"main board" of the Warm Tube Clock.

  • Page 1 Congratulations on your purchase of OSH Nixie Tube Clock. In this document you will see all steps you need to follow in order to successfully assemble the “IN-16 Nixie shield” of this device. Before we start, please make sure that you have all required parts that come for the “IN-16 Nixie shield”:...
  • Page 2 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ Assembly Heat up your soldering iron, take a deep breath and go for it. The assembly of this PCB is easier than “main board” PCB since it has very small component count but requires a steady hand. Also, take your time when soldering the Nixie tubes because you wouldn’t want to solder them crooked.
  • Page 3 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ 4. Now, using your tweezers gently place the component in its position. Push it all the way to the PCB so it kind of “glues” itself. Make sure it is centred and placed correctly! 5.
  • Page 4 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ 8. Place the PCB onto the “hot-plate” and turn it ON to pre-heat. Don’t turn the “hop-plate” to maximum temperature just yet. First put it to half, wait a minute, and then turn it up to the maximum.
  • Page 5 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ Step 2 Now we need to solder the RGB LEDs LED1, LED2, LED3 and LED4. We could have done it at the same time, together with TLC59401, but since it already came soldered on the PCB we have to do it with the soldering iron.
  • Page 6 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ 4. Your finished work should look like this. Document Version: 2011-01-05 www.elektronika.ba...
  • Page 7 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ Step 3 Now find the “103” C3 capacitor (10nF = 0.01uF). It is used to filter voltage spikes for the TLC59401 IC. It must run flawlessly since every flicker will be visible on the Nixie tubes.
  • Page 8 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ Step 4 Now locate the resistors R3 and R4: 3k9 (3.9k) and 10k, respectively. The 3k9 resistor defines the current that will be provided to the RGB LEDs (and also to the opto-couplers) – for more information about this LED current, see the TLC59401 datasheet.
  • Page 9 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ Step 5 Now locate the “2x6” male pin headers: PIN_MAL_1 and PIN_MAL2. These connect the “main board” and the “shield board”, so make sure they get soldered correctly. 1. Put these into the female pin headers on the “main board”, all the way in.
  • Page 10 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ Step 6 Now that we have all required parts soldered for TLC59401 to operate, we can test it to see if it works. This is the first time we can verify our TLC59401 SMD soldering work! 1.
  • Page 11 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ Step 7 Get all four of TLP627 SMD opto-couplers: OPT1, OPT2, OPT3 and OPT4. 1. Even though these are SMD, they are pretty big and easy to solder. 2. Place them correctly and in proper orientation and while holding with tweezers, solder (“tack”) just one pin of...
  • Page 12 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ 4. Now solder all pins of every opto-coupler to complete the work. Document Version: 2011-01-05 www.elektronika.ba -12-...
  • Page 13 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ Step 8 Now get the remaining two 910k resistors: R1 and R2. These will provide GND to two Nixie dots from two NPN high-voltage transistors from the “main board”. 1. Place them in their corresponding locations.
  • Page 14 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ Step 9 Now take the 47uF electrolytic capacitor C1. It is used as a power storage capacitor for the LEDs and the TLC59401. 1. Bend it like in the picture.
  • Page 15 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ Step 10 Now, you could skip this step but it is recommended that you do it. Get the 100nF...1uF SMD capacitor C2. It is used to filter out the supply voltage for the TLC59401 IC together with the “103”...
  • Page 16 2. For the IN-16 Nixie tube, you should solder the “lower dot” at a distance of 12.65mm from the PCB. When you solder the IN-16 Nixie tubes, you will see if you need to re- adjust the height of the Nixie dots.
  • Page 17 Warm Tube Clock Assembly Instructions for the „IN-16 Nixie shield“ 4. Now solder the “upper dot” behind it. It should go around 21.3mm from the top of the PCB. 5. Now take a minute to relax, because you must now solder 4 IN-16 Nixie tubes.
  • Page 18 Step 12 To solder the IN-16 Nixie tubes, you need some patience. This is a final step, but don’t rush it, take your time. If you solder these glass tubes incorrectly or crooked, it is very hard to fix the problem because it is pretty impossible to re-heat all pins of the tube in order to bend or twist it in place.
