Cleaning of battery contacts and fuel cells safely
In order to achieve optimal results in coating processes and in wire bonding of battery contacts, reliable and reproducible results are essential. Plasma pretreatment is used to prepare and clean the surface before bonding. Depending on the material and process to be treated, air or forming gas is used as the process gas in the plasma nozzle.
Forming gas consists of at least 95% nitrogen and up to 5% hydrogen. The low hydrogen content is in an uncritical mixing ratio. The forming gas reduces the material and can, for example, reduce oxidized copper or silver back into bare metal in a very short amount of time.
TIGRES plasma nozzle systems can be easily integrated into fully automated inline production processes and are therefore ideal for high production speeds and quantities.
Advantages of plasma pretreatment for cleaning and reduction
- Simple and clean process through cost-efficient, environmentally friendly electrical-physical plasma treatment
- Reliable reproducibility of the pretreatment, even with sensitive surfaces, because of the adjustable and regulated plasma discharge
- Full monitoring of all process-relevant parameters through real-time monitoring with TIGRES SQI (System Quality Index)
