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.
Assembly hints 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 REMOVE THEM FROM THE TAPE ONE AT A TIME ! AXIAL COMPONENTS ARE TAPED IN THE CORRECT MOUNTING SEQUENCE ! You will find the colour code for the resistances and the LEDs in the HALG (general manual) and on our website: http://www.velleman.be/common/service.
