Obsolescence is something that many vendors dread. But fear not, help is out there. Just because a chip or a board is no longer available from your supplier, you may be able to find a replacement part, and you don’t need to build it yourself. Vendors like GDCA specialize in replacing parts that are no longer available. How do they do that, and is it a wise choice to continue with a product that’s no longer in production? Those are some of the questions I asked of “obsolescence expert,” Ethan Plotkin, the CEO of GDCA in this week’s Five Minutes With…discussion.
