The constant evolution of new tools, materials, and methods for rework could make the process more reliable and repeatable. These improvements vary from being relatively simple using polymer stencils to more complicated using laser technology. One should stay abreast of new developments by constantly seeking for innovative ways to improve rework methods. Therefore, Computer Systems research team is currently engaged on work relating to a new BGA rework method by the development of a family of new non-metallic stencils that are made from elastomeric or semi-elastomeric materials that are initially attached to the lower part of the BGA and that finally are permanently attached between the BGA and the PCB. Similar methods currently in use employ non-metallic stencils that are made from polymeric materials that are initially attached to the PCB and that finally are permanently attached between the BGA and the PCB.
Computer Systems Laptop Repair Workshop (CSLRW) was established in 2007. CSLRW is equipped with state-of-the-art electronic systems and machinery to include a BGA rework station, a laser cutting/drilling machine, and an optical microscope together with uniquely developed skills of individual operators. The new elastomeric/semi-elastomeric stencils are being produced in the newly set up Computer Systems Materials Research Laboratory (CSMRL) in conjuction with CSLRW. CSMRL possess high expertise in many aspects of materials research to include adhesive bonding, polymer composites, cements and cement composites, metal composites, bitumens and materials recycling to name the least (see List of Publications). Hence, in depth knowledge in the field of materials research is being transferred to the field of computer hardware repair to produce a family of new elastomeric/semi-elastomeric stencils and a reliable, predictable, and repeatable new rework method that is hoped could introduce CSMRL to the research community. In addition, the results of the project and forthcoming publications are expected to increase the number of national and international customers and to reduce computer waste and the need for imported laptops. It is estimated that over 100,000 discarded laptops in Greece could be back from the brink of being hauled to a dump while in the EU alone more than 10,000,000 laptop owners could benefit.

Computer Systems laboratories offer repair and data recovery services since 2008. We are the only SME workshop coofunded by Greece and EU for scientific research on BGA rework methods and on Data recovery. Thanks to our research work we can offer the highest success rate on all our services for the lowest possible cost. We also offer professional equipment, training, support and consumables for computer repair workshops. From single customers who want to repair just a broken iPhone to chain shops that want to set up a network of repair workshops, Computer Systems laboratories can offer the best complete solutions.
