Assembly

(Skipping this can lead to troubles ! )
Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.

Make sure you have the right tools:

• A good quality soldering iron (25-40W) with a small tip.
• Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections. When sol-der rolls off the tip, it needs cleaning.
• Thin raisin-core solder. Do not use any flux or grease.
• A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they can- not fly towards the eyes.
• Needle nose pliers, for bending leads, or to hold components in place.
• Small blade and phillips screwdrivers. A basic range is fine.
  For some projects, a basic multi-meter is required, or might be handy

Assembly Hints

• Make sure the skill level matches your experience, to avoid disappointments.
• Follow the instructions carefully. Read and understand the entire step before you perform each operation.
• Perform the assembly in the correct order as stated in this manual
• Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.
• Values on the circuit diagram are subject to changes.
• Values in this assembly guide are correct*
• Use the check-boxes to mark your progress.
• Please read the included information on safety and customer service
  Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’ on a separate leaflet.

Soldering Hints

• Mount the component against the PCB surface and carefully solder the leads
• Make sure the solder joints are cone-shaped and shiny
• Trim excess leads as close as possible to the solder joint
