61m² Cleanroom for RM Precision

Case study:

The PanelBloc cleanroom

This PanelBloc cleanroom of approximately 61m² for RM Precision, featuring ISO Class 6 & 7 certification, was installed at their facility in Nijverdal. Based in Nijverdal (The Netherlands), RM Precision is a supplier of high-precision turned and milled components for the high-tech industry. By combining advanced machinery with highly skilled personnel, they deliver exceptional precision mechanical products.

For RM Precision, as for many other Tier 2 suppliers in the high-tech industry, maintaining substantial control over the various disciplines within their processes is critical. Developing a dedicated cleanroom facility alongside their investment in state-of-the-art machinery is a strategic move that fully supports their overarching vision.

Cleaning requirements for Grade 4 and 2

ASML applies cleanliness grades to classify the cleanliness requirements of components and tooling within their manufacturing process. This is critical in the semiconductor industry, where even microscopic contamination can impact machine performance.

To meet the demands of Grade 4 and Grade 2 cleaning, the cleanroom design incorporates advanced fan filter units equipped with HEPA H14 main filters and high-capacity pre-filters. Among other benefits, this configuration enables achieving and sustainably maintaining ISO Class 6 compliance within the primary and UV inspection areas. Consequently, RM Precision can effectively execute Grade 4 and Grade 2 assembly, cleaning, and packaging operations within this optimized cleanroom environment.

Why is this important?

Particulates can cause defects in the extremely fine structures that ASML equipment projects onto silicon wafers. Therefore, these cleanliness specifications are strict and must be strictly adhered to by both ASML and its supplier network.

Integration with an industrial cleaning system

In parallel with the cleanroom, a Karl Roll – Special A vapor degreaser was installed, sourced from specialist supplier Oude Reimer. Components undergo a thorough pre-cleaning process before being transferred into the cleanroom via a roller conveyor system. Directly integrated with the main cleanroom area, the system is designed to deliver optimal cleaning performance and support Grade 2 packaging and delivery of high-tech products.

Cleanroom layout

The cleanroom layout and equipment configuration have been optimized to streamline material flow toward internal inspection and packaging workstations, enhancing process efficiency. Through the integration of a custom-designed UV inspection room, components can be evaluated and, if necessary, routed through additional cleaning stages prior to final packaging.

Comfort and efficiency for personnel

Installing lighting engineered to a predetermined lighting plan, combined with furniture positioning based on an optimized layout, maximizes operational efficiency. The resulting minimization of internal movement directly contributes to improved throughput times.

The supply of appropriate cleanroom furniture and expert product consultation, tailored to the operational requirements of RM Precision, was fully managed by ProCleanroom's Accessories & Consumables department. Through joint collaboration between these specialists and RM Precision, specific needs and requirements were evaluated, resulting in a tailored product portfolio. Managing this execution in parallel with cleanroom construction enabled RM Precision to occupy and utilize the facility immediately, making it a true turnkey solution.

Outfitting and Consultation

Outfitting and consultation for selecting the proper cleanroom consumables tailored to Pfeiffer's operational workflow were fully executed by ProCleanroom's Accessories & Consumables division. Working closely with Pfeiffer, specialists evaluated requirements to assemble a tailored product package. Running this process concurrently with cleanroom construction allowed the space to be outfitted and operational immediately upon handover.

Direct benefits for the user:

Complete turnkey solution – design, installation, ISO validation, garments, and furniture: a single point of contact.
Maximum cleanliness performance thanks to fully flush walls and ceiling.
Premium aesthetic appearance for client and supplier presentations.
Lowest power consumption and operational costs in the market.
