Netstal POI 110.240.5428 PCB Board Diskjet 600 Steag Unijet CD Replication

Netstal POI 110.240.5428 PCB Board Diskjet 600 Steag Unijet CD Replication System

This is a Netstal POI 110.240.5428 circuit board removed from a Steag Firstlight Unijet 60144 CD Replication System that also incorporated a Netstal Diskjet 600 Injection Molder. The board is a multi-IC card-edge module identified on-board with the silkscreen designation POI 110.240.5428, and carries a secondary label on its card handle reading POI 110.240.5429b. It features dual high-density card-edge connectors along two opposing edges for integration into the host system's backplane.

Applications

The Steag Firstlight Unijet 60144 is an integrated CD replication line that combines an injection molding station — in this case a Netstal Diskjet 600 — with metallization, lacquering, and printing stages to produce finished optical discs at high throughput. These systems were widely deployed by disc replicators in the late 1990s and early 2000s when CD production was at its commercial peak. The Netstal Diskjet 600 was a purpose-built injection molder designed specifically for optical disc substrates, producing the polycarbonate disc blanks that the rest of the line then coated and finished. Control and I/O boards like this POI module handle the low-level I/O, sequencing, and interlock logic that coordinate the molder and downstream stations. Replacement boards of this type are sought by facilities that still operate legacy Unijet lines for CD or DVD production, or by engineers maintaining Netstal Diskjet injection molding equipment.
