Chamber cleaning system
Changing range of parts, small to medium production volumes, several process steps in one closed chamber. For bulk parts usually as flood washing inside the chamber.
A component that will later process signals forgives no particle in the housing.
Electronics and control technology
Control components, defined residual contamination values, technical cleanliness, traceability per part, process reliability — that is the task. The system is its result.
1 · The challenge
Residual contamination does not stand beside the other requirements, but ahead of them
Residual contamination, technical cleanliness and cycle time are a topic in every industry. Here, residual contamination is the figure a project is measured by.
What follows from that is a different weighting, not a different process. The task remains: reach and verify defined residual contamination values. What changes is the tolerance towards the individual case. Where an outlier is not acceptable, a good average result is not enough — what counts is repeatability, and it counts that it can be demonstrated.
And from that follows a second topic that is secondary in other industries: traceability. Not „the batch was clean“, but „this part was“.

What this page expressly does not mean
We do not clean printed circuit boards or populated subassemblies. Flux removal, subassembly cleaning and the processes of electronics production in the narrower sense are not part of our portfolio.
The dividing line runs at the housing: we clean the housing before the subassembly goes in — not the subassembly inside it.
What counts about the component
Small, precise geometries
The workpiece fixture decides accessibility and sequence.Blind holes and narrow channels
Spray shadow — the medium has to be brought in differently.Defined residual contamination values
The verification is part of the task, not an extra.Sensitive functional surfaces
The process must not change the component.
The point that is overlooked with plastic housings
Plastic parts can be electrostatically charged. That is why they often have to be discharged before the cleaning process so that chips and fine particles can be removed reliably.
That is not a side issue but the reason why a cleaning process on plastic housings can fail even though it is technically designed correctly: an electrostatically charged part holds on to the chip the medium would actually carry out — and the residual contamination value is not reached without anything being wrong with the cleaning itself. That is why discharging belongs in the process chain, not in the troubleshooting afterwards.
Materials: we clean aluminum, steel, stainless steel and plastics alike. There is no limit at the material — but there are materials that demand an additional process step.

3 · Which requirements follow from that
Cleanliness as a prerequisite for the joint itself
The required component cleanliness depends on the downstream manufacturing process. With control components that is often a joining operation — which turns cleanliness into a prerequisite for the joint, not only for the later function.
Of all requirements, residual contamination weighs heaviest here — ahead of cycle time, ahead of drying, ahead of everything else. Verification follows your specifications or the relevant standards such as VDA 19 / ISO 16232, where these are required. The analysis is carried out by an independent, accredited test laboratory — not by us. For a requirement that stands above all others, the figure comes from a third party that is not bound by our instructions.
Traceability down to the individual component
Via barcode or DataMatrix recognition, the processing program can be selected per part and the result written back per part. That depends on the project, it is not standard — but it is the point at which this industry differs from others.
4 · Which solutions answer this
The machine type follows the component and the cycle, not the industry
Immersion cleaning system
When the workpiece or bulk parts have to be fully immersed so that the medium reliably reaches all areas. We add ultrasonic cleaning where it makes sense.
Continuous and rotary indexing cleaning systems
With high production volumes in short cycles, with a range of parts defined at the planning stage.
For very high drying requirements we offer vacuum drying. The water quality is a design factor of its own — city water, softened or demineralized water, depending on the residual contamination requirement and the downstream process. Where needed, we design the water treatment as well and integrate it.
Automated loading and unloading, linking and buffering we deliver with the system — with robot, handling or material flow and conveying technology from our own design engineering, provided it pays off.
5 · Where we advise against it
It is precisely here that the limit of what is technically achievable is tested
Unrealistically low residual contamination requirements
We decline them before the quotation, not at acceptance.Spray shadow when spraying
With small components with blind holes, immersion and flooding deliver the better results.We do not build solvent systems
They are not part of our offer.Automation that does not pay off
With low production volumes, frequently changing products or high changeover effort we recommend none.
6 · Where we stand in this industry
What is backed by evidence — and what is not
A supplier who fills an industry page without evidence cannot be checked even where he is right.
Backed as experience
Manufacturers of electronic components and control technology are among our customers. Control components are one of the component classes for which we have designed high-pressure systems. And in this industry, parts cleaning systems and automation solutions of ours are installed.
Not backed — and therefore not claimed
We hold no documented reference for a water jet deburring system in this industry. And we do not say in which machine type the components named were processed — that assignment is not available to us in a reliable form.
The same component class — control components — also carries the automotive line, there backed by delivered systems.
Questions and answers
Frequently asked questions from electronics and control technology
Do you build systems for the electronics industry?
Yes — electronics is one of the industries in which systems of ours are already installed, in industrial parts cleaning as in automation. What is meant are mechanical components, above all control components, not the cleaning of populated subassemblies. For a water jet deburring system in this industry we hold no documented reference — which is why it is not listed here. The cleanliness requirement comes, as everywhere, from the downstream process, not from the system.
Applications
One task from this industry
One worked-out task is assigned to the electronics industry. What tips the balance in it is on its own page.
Every case lists the design factors, the possible system concepts and the processes in detail — here is only what it is about.
High technical cleanliness
It is not cleanliness itself that is difficult, but its verification: a component that is clean, but not demonstrably clean, cannot be used in a manufacturing operation with a verification requirement.
The assignment classifies — it claims no project. And it decides nothing about the system: which concept a task needs arises from the interplay of the design factors, not from the industry.
