SWITCHABLE FREQUENCY ULTRASONICS
IMPROVE REFURBISHMENT PROCESS
Ultrasonics get cleaning quality on the right track
Brush Traction, one of the UK's most highly experienced railway stock refurbishment companies, witnessed an improvement in cleaning quality following the installation of a Kerry ultrasonic cleaning system.
The Pulsatron UCR 1500 is used at Brush Traction to remove brake dust and general debris from PCBs that form part of traction propulsion systems. The tank is fitted with a Neptune dual-frequency generator controller, enabling ultrasonics to operate at either 35kHz or 70kHz; the higher frequency protects delicate components without sacrificing cleaning efficiency.
The Kerry unit was purchased as part of an initiative to improve Brush Traction's refurbishment process. For Dick Mabbutt, Group Electronics Engineer, the choice of supplier was relatively straightforward: "We were looking for a manufacturer who could offer switchable-frequency ultrasonics, and Kerry was the only one we could find in the UK."
Having passed through the UCR tank, boards are visually checked for cleanliness and then subjected to further electrical tests. Prior to the arrival of the UCR system, cleaning was carried out by hand.
The cleaning process comprises three stages. Following an ultrasonic clean in an aqueous solution of CP10, PCBs undergo two rinse stages - the first in tap water, the second in deionised water from a hand-held spray. Boards are then left to drip dry.
