Visit to Jemstech

A iThemba LABS/Wits team from the High-throughput electronics laboratory within the Institute for Collider Particle Physics visited Jemstech. This electronics plant has populated the electronics boards for the first prototype made in South Africa of the Low Voltage Power Supplies (LVPS) for the upgraded Tile Calorimeter of the ATLAS Detector at CERN. The LVPS will power the future on-detector electronics of the Tile Calorimeter that is being designed for the Phase-II upgrade of this detector. South Africa is responsible for the production of over 1000 of these boards, where the PCBs are manufactured in Trax, Cape Town and passed to Jemstech for population.

The iThemba LABS/Wits team in charge of the South African production is composed of Edward Nkadimeng, Nkhosiphendule Njara, Thabo Lepota, Ryan McKenzie, Charles Sandrock, Roger van Rensburg and Bruce Mellado.

The purpose of the visit is to discuss the production of the second and close-to-final prototype of the LVPS. We discussed quality control issues, details of the bill of materials and other components. Discussed the implementation of Artificial Intelligence in the process of quality control assessment.
