Clean Room - VIDEOFONIKA

Clean Room ISO 5 – a clean environment for precise technologies

Videofonika’s ISO 5 Clean Room is a modern, fully validated cleanroom compliant with PN-EN ISO 14644:2016. We have optimized the environment for the production of active displays and optoelectronic processes — from HEPA H13 filtration, through the Forbo Colorex SD antistatic flooring, to the precision BubbleFree 2240 GLED PRO lamination table. This infrastructure provides repeatability, minimizes defects, and prepares production for future technologies.

A Controlled Environment, Built for Quality

To meet the highest demands of display and optoelectronic component production, we have launched an ISO 5 Clean Room, designed and validated in compliance with PN-EN ISO 14644:2016 standard.

In practice, this means controlling airborne particles, stable environmental conditions, and eliminating sources of contamination and electrostatic discharge – essential conditions for optical film lamination and precise assembly operations.

Construction and Installation – Clean Technology

The clean zone construction is based on Kingspan panels, selected for environments with high hygiene requirements.

Design features:

Resistance to corrosion and chemicals,
Smooth, easy-to-maintain surfaces,
Tight joints to minimize particle migration.

Such design allows for easy sanitization and long-term maintenance of ISO Class 5.

ISO Class 5 (Particles 0.5 µm)
Measurement results at 6 points

Particle concentration limits comply with ISO 14644-1:2015 for all classes (ISO Class 4–8) at a particle size of 0.5 µm.

Forbo Colorex SD Antistatic Flooring

A conductive ESD flooring Forbo Colorex SD coveres whole area of our clean zone.

Key features:

Surface resistance: 10⁶–10⁸ Ω
Throughout material uniformity (no layers)
Capability of regeneration by polishing
High resistance to chemicals and disinfectants
Permanent connection to the grounding grid

Result: Minimized ESD risk and protection of sensitive electronic components.

Air Filtration System – ISO 5 Cleanliness

The Clean Room takes advantage of a Fan Filter Unit (FFU) system with HEPA H13 filters located above the work stations.

Key features:

Filtration efficiency ≥ 99.995% for particles ≥ 0.3 µm
Laminar (unidirectional) flow above work areas
Smart control and monitoring of environmental parameters

This ensures the air purity stability necessary for optoelectronics production.

Tech Center – Bubble Free 2240 GLED PRO

The heart of the Clean Room is the Bubble Free 2240 GLED PRO – an industrial-grade lamination table for the precise bonding of films and optical layers to glass.

Benefits of the Bubble Free Table:

Bubble-free application,
Capability to work on PMMA, glass, foamed PVC, and other surfaces,
3-layer glass + GLED backlight for real-time quality control,
Innovative lower bridge – free access above the roller (facilitation for a single operator work).

Specifications:

Model: BBF 2240 GLED Pro
Working area: 3600 × 2140 mm
Table format: 4000 × 2180 mm
3-layer glass construction + LED backlight + 5mm PVC

Validation and quality control

Our Clean Room is covered with a continuous parameter monitoring system (particles, temperature, humidity, grounding continuity), which allows us to maintain ISO Class 5 in production mode.

Benefits for production processes

The new zone delivers measurable operational and quality benefits:

Critical level controlling of air purity for displays production,
Reduction of surface defects and micro-contaminants,
Higher repeatability and stability of production results,
Increased efficiency of lamination and precision assembly,
Preparing infrastructure for the implementation of micro- and nanostructure technologies.

For whom?

Manufacturers of displays and optoelectronic components – assembly and lamination in a controlled environment.
Research laboratories and R&D teams – development work on micro- and nanostructures.
Integrators of AV and electronics systems – testing and final assembly of components in contamination-free conditions.
Industrial partners – processes requiring high repeatability and minimal defects.

Why?

Compliance with the PN-EN ISO 14644:2016 standard (ISO class 5) – a guaranteed production environment.
HEPA H13 filtration and laminar airflow – air purity confirmed by measurements.
Forbo Colorex SD antistatic flooring – continuous ESD discharge.
BubbleFree 2240 GLED PRO – precise lamination without optical defects.
Continuous monitoring and validation – real-time parameter stability.

Our Clean Room is powered by a 31 kWp photovoltaic system, which is additionally supported by a 60 kWh energy storage unit. This solution significantly reduces power consumption required for Clean Room operation, and thanks to the FFU-based filtration system, we can efficiently regulate its consumption. This contributes to maximizing self-consumption and reducing greenhouse gas emissions.
