Our background

Computer Systems began operating in 2008 as a laptop repair and data recovery laboratory. From the beginning, our work focused on laptop motherboard repair and on the technical problems caused by BGA components in computers, graphics cards and other electronic devices. The laboratory invested early in BGA processing stations, diagnostic tools and specialist repair equipment, while developing practical repair methods for recurring electronics-repair problems.

In September 2012, Computer Systems undertook a research project with a budget of EUR 166,320 to develop a scientifically and practically acceptable defect-repair method for BGA-component processing by small laboratories using cost-effective equipment. The project team included a PhD research engineer, an electrical engineer, a computer engineer and the wider technical team of the laboratory. The project was completed in August 2015 and contributed to the development and manufacture of products such as K4-PRO, K5-PRO, UPSIREN U6 PRO, BGA COAT and CS-FLUX.

In November 2013, Computer Systems undertook a second research project with a budget of EUR 53,000 focused on data recovery from damaged storage media and on the development of suitable tools. This work contributed to products such as FW-FXR, FileChecker by CS and Diagnostics for Seagate (DfS).

The results of these research activities, together with continuous laboratory experience, led Computer Systems to develop repair methods, thermal interface products and technical tools used by repair professionals, data recovery companies and electronics-service laboratories in Greece and abroad. Computer Systems products have been exported to more than 90 countries.
