The device automatically scans nMBVR-920 SMT production lines for PCB substrate (or packaging line) on multiple bar code and identification, output to the rear end of the device (for an additional middleware import, if this demand, please contact our sales staff) or stored in a CSV file, a database to track statistical analysis. nMBVR-920 stand-alone version of the software system and network versions, standalone version only multiple barcode values are stored in the native CSV file for additional development of middleware called, make up the downstream device can not record production based on the product barcode, network version supports MSSQL database, you can identify multiple nMBVR barcode data associated downstream production data is stored in a common database for data recording and tracking. nMBVR-920-D for the two-track system that supports two SMT production lines while production, nMBVR-920-S for the monorail system only supports a SMT production line.
