Electroglas 100935E board

Electroglas 100935E is a wafer‑probe control board used in semiconductor probing systems, typically interfacing with probe cards and power supplies. Common failure points on this model include burnt or tripped protection diodes on the I/O lines, degraded solder joints to the high‑speed analog switches, and aging electrolytic capacitors on the main power rail that can cause voltage droop under load. Begin troubleshooting by verifying 12 V/5 V supply rails with a multimeter, inspecting for visible arcing or corrosion on the board, and checking all I/O connectors for continuity and proper signal integrity before proceeding to component‑level testing.[oss-gpt-20b]
