The PanelBloc cleanroom
This c.a. 61 m², PanelBloc cleanroom for RM Precision, with a ISO-clasisfication of 6 & 7 is installed on their premise in Nijverdal. RM Precision is a supplier of high-quality turned an milled parts for high-tech industry and is based in Nijverdal (The Netherlands). By combining their state of the art machinery with highly trained employees, they are able to realize very precise mechanical products.
For RM Precision, as for many other Tier 2 suppliers in the High-Tech industry, maintaining significant control over the various disciplines within their processes is paramount. The development of their own cleanroom facility, alongside their investment in a cutting-edge machine park, is a strategic move that fully supports their overarching vision.
Cleaning Requirements for Grade 4 and 2
ASML employs cleanliness grades to classify the purity requirements for components and tools within their manufacturing process. This is crucial in the semiconductor industry, where even microscopic contamination can impact the performance of their machines.
To meet the demands of Grade 4 and 2 cleaning, the cleanroom’s design incorporates advanced fan filter units equipped with HEPA H14 main filters and high-capacity pre-filters. This configuration allows for the achievement and sustained maintenance of an ISO Class 6 classification in both the main and UV inspection areas. As a result, RM Precision can effectively conduct Grade 4 and 2 assembly, cleaning, and packaging tasks within this optimized cleanroom environment.
Why is this important?
Particles can cause defects in the extremely small structures that ASML machines project onto silicon wafers. Therefore, these cleanliness requirements are stringent, and both ASML and its suppliers must adhere to them rigorously.
Integration with an industrial cleaning system
Installed in parallel with the cleanroom was a Karl Roll – Special A, vapor degreaser, sourced from the specialist supplier Oude Reimer. Products are subjected to a thorough pre-cleaning process prior to being transported into the cleanroom via a roller system. The system is directly intergrated with the main cleanroom area, designed to achieve optimal cleaning performance and support Grade 2 packaging and delivery of high-tech products.

The configuration of the cleanroom’s layout and equipment is optimized to streamline product flow to in-house inspection and packaging workstations, thereby enhancing process efficiency. Including a purpose-built UV inspection room, products may be examined using this method and then proceed to additional cleaning stages, if required, before being packaged.
Comfort and efficiency
Installation of lighting according to a pre-determined lighting plan, coupled with furniture placement based on a pre-set layout, serves to optimize the cleanroom’s efficiency. The resulting minimal internal movement directly contributes to improved lead times.
The provision of suitable cleanroom furniture and expert consultation regarding product selection, aligned with RM Precision’s operational needs, was comprehensively managed by ProCleanroom’s Accessories & Consumables department. Through a collaborative effort between their specialists and RM Precision, specific desires and requirements were assessed, leading to a tailored product offering. This parallel execution alongside the cleanroom build ensured RM Precision could immediately occupy and utilize the space, rightly characterizing it as a complete turnkey solution.
Direct benefits for the user:
- Full turnkey solution – design, hardware, installation, furniture and accessories: a single point of contact.
- Maximum cleanliness performance due to fully flush walls, floor and ceiling.
- Maximum cosmetic appearance for client and supplier presentation.
- Lowest power consumption and operating costs in the market.
