Support for Legacy Projects
Adjustment and total redesign of legacy customer projects, keeping the original parameters of the design and modernizing the component base with the latest developments in the IC industry. Optimizing the power consumption of battery powered communication modules and extending the working distance. Example:
Redesign of legacy controller, by replacing obsolete microprocessor on customer controller with an up to date chip, by preserving the mechanical footprint of the original, keeping the same interfaces, software redesign and update, PCB redesign, schematics update, preserve exactly the same functionality so that the new design can fit as a spare part in the target machine, as well as using the same test points on the PCB to enable production testing with legacy equipment.
Restoring the physical appearance of a legacy PCB from pictures, Gerber files and other relevant information even in case when there is no scaling information or dimensions.
