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 :
- – 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
DO NOT BLINDLY FOLLOW THE
ORDER OF THE COMPONENTS ONTO THE TAPE.
