THE CERAMIC SCREWDRIVER

In the Far East and in the USA hardly any electronic piece of equipment leaves its factory without first having been adjusted with a ceramic screwdriver. However, this tool is only rarely used in European companies. In the electronics branch ceramic screwdrivers are important tools both for producing and repairing. Metal screwdrivers can for example affect equipment in which frequencies need to be adjusted. They can cause short-circuits and transfer static electricity form a person to the device. In order to prevent these problems the use of a ceramic screwdriver is recommended. 

Despite the fact that a ceramic screwdrivers have been reasonably priced for some time now, they are not used on a large scale. Few electrical engineers are aware of their unique properties. They are non-magnetic, non-inductive and consequently indispensable when adjusting sensitive electronic equipment. Adjustment mistakes can be considered a thing of the past. 

When a regular screwdriver is taken off the adjustment component, there is a considerable chance that the painstakingly acquired value changes again. This is for example a common problem in the case of circuits which must amplify smally currents (e.g. in meas- 

The inductance of adjustable coils with a ferrite core and the capacity of trim capacitors are strongly influenced by metal screwdrivers. It is important for trim capacitors and coils in oscillator circuits to be adjusted in the precise centre of the resonance area. Should this occur at the side, then oscillators sometimes fail to REACT when there is question of a change in temperature or ageing of components. Thus more situations can be mentioned in which you can benefit from the advantages of ceramic screwdrivers. 

The manufacturer of ceramic screwdrivers - JAWA - has developed a high-quality, reasonably priced screwdriver. It is made of zirconia (zirconium oxide) ceramics, which is harder and more durable than ordinary ceramics.
