Since 1999
When the OEM no longer helps, we do
Since August 1999, APEX Semiconductor has supported a wide range of photo equipment from OEMs that no longer exist – for example Convac-Fairchild, B.L.E. Laboratory Equipment, SSE (Sister Semiconductor Equipment), SVG (Silicon Valley Group), ATMsse and APT (Convac) – as well as systems whose OEMs have ceased support because of their age.
We keep these machines productive with on-site service, repairs, refurbishment and upgrades, backed by our own stock of new and pre-owned spare parts.
