CP5176 Assembly guide
Safety warning
The kits are main powered and use potentially lethal voltages. Under no circumstance should someone undertake the
realisation of a kit unless he has full knowledge about safely handling main powered devices.
Please read the "DIY guide" before beginning.
Print or open the following documents :
• CP5176 Schematics
• CP5176 Components layout
• CP5176 Parts list
• CP5176 Setup guide
Follow this guide from item number 1 till the end, in this order. The assembly order is based on components height, from
low to high profile, in order to ease the soldering process : The component you are soldering is always taller than the
previously assembled ones and it is pressing nicely against the work area foam.
Soldering
All the PCB holes are metallized. It means the connection between the top and bottom pads is already
done. The parts must be soldered only from below (unless differently stated).
Use only small diameter solder, 0.5 or 0.7 mm, 1mm maximum. Use the minimum possible amount of
solder. Bad joints are almost always caused by too much solder.
Cut the component leads and pins totally flush with the PCB after soldering. A too long tail could create
an electric connection with the side plate.
Here are two excellent introduction to soldering videos:

PCB split
Split the second PCB along the groove. Use extra
thin sandpaper to clean up all the rough sides.
