High Purity

Next level cleaning

High Purity

Cleaning for Semiconductors, Optics & Precision Engineering

Industrial ultra-fine cleaning at the atomic level – with validated process reliability

High Purity Cleaning – because every detail counts.

In the semiconductor, optics, medical technology and precision engineering industries absolute cleanliness determines performance and reliability. When components with complex geometries need to be cleaned of particles down to 0.5 μm particle size and residue-free at the molecular level, standard technology is not enough. At BvL, we combine process and material expertise with precisely tailored system technology, aligning the cleaning process exactly with your requirements.

In our technical center, results are verified under real-life conditions. Test runs with original components – including UV-A inspection in our in-house darkroom and particle measurement (PMC) – provide reliable evidence of cleaning performance.

Our technical consulting and BvL‘s global service support you, whether as a clean service provider or as a manufacturer, on the path to stable and traceable processes.

Our solution:

Flexibly configurable precision cleaning systems

For the highest demands, with measurable cleanliness and reliable support in all project phases. The modular systems can be precisely adapted to customer-specific processes. The range of applications extends from oil- and greasefree pre-cleaning to qualified final cleaning in accordance with grades 1–4.

At BvL, we are developing the next stage of industrial precision cleaning – precise, reproducible, and tailored to your application.

Possible processes

Vacuum impulse technology (VIT)
Deep cleaning using implosion power: innovative pressurechange process for improved media exchange and enhanced contaminant removal. Ideal for components with complex geometries, narrow channels, and blind holes. The VIT process can be integrated into any Niagarastrong> series system and, in the future, also into the Atlanticstrong> immersion cleaning system.

Ultrasonic cleaning
e.g., 40, 80, and 132 kHz, multi-frequency systems, ultrasonic generators with sweep function for delicate geometries.

Spray/flood cleaning
Powerful all-round cleaning through special nozzle frames and flooding of the cleaning chamber (continuous partial flooding, full/vacuum flooding, recirculating flooding)

Immersion cleaning
Perfectly coordinated combination of different cleaning processes in a multi-stage system. The treatment processes and number of tanks can be individually adapted.

Drying
Vacuum drying, recirculating air and hot air drying with HEPA filter, air blow-off, infrared drying – used alternatively or in combination

Our systems:

Configurable to your needs – perfectly matched to your component and your process

NiagaraUp:

Basket cleaning system with Vacuum Impulse Technology (VIT)

The NiagaraUP combines a compact design with high process depth for top-level cleanliness.. All process steps are carried out in a single chamber saving space.

The system design prevents recontamination and cross-contamination. Amoung other things through, electropolished surfaces and a rounded chamber design, as well as special processes such as chamber cleaning with UPW (ultrapure water), rapid complete draining, etc.

Process

The key feature here is Vacuum Impulse Technology (VIT), which reliably removes residues even in capillaries, boreholes, and cavities. In addition, spray and flood cleaning (stepless partial flooding, full/vacuum and recirculating flooding) as well as HEPA-filtered hot air and vacuum drying extend the process into a complete solution for high purity requirements. All processes are individually configurable.

Atlantic:

Atlantic immersion cleaning system

The Atlantic multi-chamber immersion system is an optimal inline solution for the highest cleanliness requirements with high throughputs.

Components are immersed by means of an automated portaltransfer system into sequentially arranged tanks with differenttreatment stages. The number of tanks can vary.

Process

Immersion cleaning, phosphating, spraying, injection cleaning, ultrasonic cleaning (optional), rinsing, passivation, and optional drying are available. This wide range allows precise configuration of the cleaning process.
