They invested in a Miniwash 480 machine to remove residual flux from resistor leads, which are used to limit or control the flow of electricity through different types of circuits. The residual flux is left over on the components after soldering, and TT Electronics use only filtered rain water in their Miniwash to remove this soiling. As a result, their production times have been reduced considerably.

The Miniwash 480 uses hot water and an environmentally friendly detergent, which is sprayed with a fixed spray boom above, to the side and below the rotating mesh basket, and washes components thoroughly. After closing the lid, the timer can be turned to the desired wash time and the machine automatically starts. During the wash cycle the basket rotates and the components are cleaned quickly, and due to the temperature of the detergent, they flash dry in seconds at the end of the cycle.

TT Electronics think that it is very important for resistor leads to have a machine finish in order to maintain the integrity of them, as any slight fault can cause serious malfunctioning in electrical circuits. As well as this, contaminated parts generate very little or no returns from customers, therefore, it is important that they are finished effectively.
