The Openair-Plasma process, with its latest developments, from Plasmatreat will be presented at Apex Expo in San Diego, USA, in February 2020.
Achieving reproducible process sequences, high system reliability, low manufacturing tolerances, stable quality levels and data-supported automation are process specifications required in today's electronics production. These and the associated traceability are only possible with exact process control and monitoring. Plasmatreat says the company offers this form of monitoring with its Openair-Plasma process — the new Plasma Control Unit (PCU) with the latest development for process control.
The company notes that the PCU provides users the guarantee of reproducible results when using Openair-Plasma in electronics production, offering all process data in real time. The newly designed HMI ensures high data accessibility. Furthermore, the process data is logged and remains available for future evaluation and traceability. Nico Coenen, Business Development Manager Electronics Market at Plasmatreat also added: “I can only achieve a reproducible production process if I can ensure that each component has been treated with the same plasma intensity. This reproducibility must also be guaranteed beyond one facility so that the same quality is achieved in all production lines.”
The control unit has been designed for application in smart process lines with an industry 4.0 usage and is connected via an EtherCAT / CANopen gateway. As such, the interfaces are defined for use in automated systems such as robots, while its integration into existing production lines is also possible.
Depending on the type and number of plasma nozzles used, up to four PCUs can be connected in series, the company says. This allows for a modular setup in which the individual plasma jet can still be operated and controlled separately by the Plasma Switch Automatic (PSA).
