IVS Accuvision 200 0001-00055 ECB Vacuum System Control Board PCB Module

IVS Accuvision 200 0001-00055 ECB Vacuum System Control Board PCB Module

This is the ECB (Electronic Control Board) for the IVS Accuvision 200 vacuum system, identified by assembly number 0001-00055. The board is a multi-IC populated PCB module that serves as the central control card within the Accuvision 200 vacuum process system, managing electronic control functions for the vacuum system's operation. A copyright date of 1983 is printed on the board, placing this card in the early-1980s era of dedicated industrial vacuum control electronics.

Applications

The IVS Accuvision 200 is an industrial vacuum system used in thin-film deposition, sputtering, and related vacuum process applications — equipment common in semiconductor fabrication, optical coating, and research environments from the early 1980s onward. The ECB (Electronic Control Board) is the system's main process control card, handling logic, sequencing, and I/O within the vacuum system's card cage. Replacement and spare ECBs like this one are sought by facilities still operating Accuvision 200 systems, as well as technicians performing depot-level repairs. The CD74HCT646EN bus transceivers and the mixed-signal AD78463JN IC are characteristic of 1980s industrial control board designs that bridged analog process signals with digital control logic.
