Trouble-shooting can be divided into two kinds of situations: repair and development.

In repair, you know that the equipment you are trouble-shooting did, at one time, work. Maybe a component failed. You need to find out what went wrong and then to fix it.

In development you are working on prototypes. When it doesn't work properly there are three possibilities. First, there may be a faulty component. Second, the breadboard or prototype wasn't built according to design. Third, there may be a fault in the design. Usually, there is a combination of all three in an early prototype.


Don't do anything that may harm you, others, or the equipment you are working on. Remember that high voltage can cause burns, and a shock across your chest can stop your heart.

For this reason you are not allowed to work on your own in the Laboratories.

Anti Static Precautions

ESD sensitive devices may be protected by one of the following methods:

Grounding is achieved by connecting the work area, the operator and the items being worked on, to a known good grounding point with grounding straps.

Isolation and neutralization is achieved by using the conductive protection materials.

ESD safe work areas and protective equipment

Work stations where static sensitive equipment is handled must be equipped with the following equipment:
