Assembly hints

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

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.aspx
