5. ASSEMBLY INSTRUCTIONS ELECTRONICS

First of all please check if all parts in the kit are complete.

5.1. Soldering job

The layout on the PCB clearly shows where to mount each component.

When you want to see more detailed information, please study the

diagram, pictures and drawings for extra help and information.

When we assemble a PCB we always start with the lowest passive

components. Normally these are the resistors followed by the capaci-

tors. After soldering, cut the wire ends of the components directly, so

you always keep enough space for the soldering of the other compo-

nents on the PCB.

Before you start soldering, we always advise to insert the active com-

ponents (transistor, IC, diode) so you already can align their pins when

they do not fit properly. Often the legs of such components need some

extra bending to make them fit. At last you solder the IC sockets or the

active components.

IMPORTANT

The Elco and IC have a polarity so you should be careful to solder

them in the correct position.

WARNING

NEVER start with the soldering of an IC and when possible always use

a IC socket to avoid mistakes. When an IC is soldered, it is very dificult

to remove it again.

TIP

The IC-pins can be bend and aligned very simple on a hard flat

surface like a table! Just put all pins inline on the table and bend the IC

carefully to the correct alignment.
