Invisitech is a privately owned company based in the south of England specialising in the restoration of high value electronics mainly in military and aerospace environments. The work is largely dealing with electronic companent obsolescence, by designing and manufacturing speialist adaptors (dealing with footprint differences, interconnections, space constraints, environmental issues, voltages and speed variations)... These allow a far greater spread of parts to be available for use by the end customer. The obsolescence work is not limited to electronic components we also manufacture obsolete mechanical parts too.  Additionally we upgrade the PCB designs without re-maunufacturing, by the concept of invisimod.. This is a new section of PCB that adds all new circuitary, footprints and features not available by wiring. Lastly we repair all mechanical faults on PCB assemblies from simple lifted pads, through to major burns...  Where design details are now missing invisitech will re-engineer any PCB assembly either as a Chinese copy or to include specific upgrades.
