Requirements in electronics
In electronics, particulate and filmic contamination affects downstream processes such as bonding, coating or potting. Clean, defined and prepared surfaces — together with the control of electrostatic charges — are a prerequisite for reliable results.
Suitable processes
Which process fits best depends on the part, the contamination and the batch size — we advise on a technology-neutral basis. For this industry, the following are particularly relevant:
- Electrostatics & ionisation — discharging and cleaning of electrostatically charged surfaces
- CO₂ snow blasting — dry, residue-free cleaning of sensitive assemblies
- Plasma & corona pre-treatment — fine cleaning and surface activation without chemicals
- Wet-chemical cleaning — aqueous or solvent-based cleaning, also of flux residues
Test the process at TeSe
Whether a process meets your industry’s requirements on your actual part is shown by a trial: 1–2 hours of testing free of charge. In-depth feasibility studies: CHF 1’200 per day, 50% creditable against a machine purchase.
