OHB Purge(OHBP)
With the OHT track system, it provides air bulk storage space for photomask pods, enhancing the space utilization rate in the wafer fab and maximizing the transport efficiency of wafer carriers between processes. The purge unit is installed through the purge pipeline layout, filling pure gas to ensure the micro-environment within the photomask pod and improving yield.

Optional configuration: Storage position: 1 cell, 2 cells, 3 cells, 4 cells
Feature Highlights:

Combined type with row frame

Integrated control of the entire Bay

Independently control of specific Shelf

Power-off sustainable Purge

Purging only when materials are present

Idle Purge

Software Description
OHBP Software
OHBP Software
The OHBP control system cleans and purges the ports of the entire bay, offering two modes: continuous purge and inductive purge. It can be equipped with RFID sensors and temperature/humidity sensors, recording the number of Foup placements and tracking temperature/humidity changes throughout the purge process. In case of abnormal RFID readings or substandard temperature/humidity, it provides real-time alarm functionality;

The Web UI interface allows for manual adjustment of the proportional valve, real-time control of airflow, adjustment of temperature, humidity, flow, and pressure monitoring ranges, and manual control of the solenoid valve's switch.

Feature Highlights:
▪ Multi-disk real-time monitoring, ensuring stability and reliability.
▪ With the MF FabScope system, it can quickly pinpoint the location of any abnormal disk status.
▪ Recipe management is supported.
