Assembly hints

1. 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.

1.1 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 solder 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 cannot 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

1.2 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, the 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.

1.3 Soldering Hints :

1- Mount the component against the PCB surface and carefully solder the leads

2- Make sure the solder joints are cone-shaped and shiny

3- Trim excess leads as close as possible to the solder joint
