Any loose particle triggers an investigation of the contamination source. **Does the particle counter measure the tray surface?** It monitors air in the Class 100 room. Tray surface particles are tested separately against the customer’s specified method and limits. **What is the effective washing width?** 950 mm. ![Class 100 clean room, DI-water wash area](/assets/quality/cleanroom-class100.webp) - [Housings & enclosures](/en/products/housings) - [Covers & shrouds](/en/products/covers-shrouds) - [Panels & fascias](/en/products/panels-fascias) - [Trays & liners](/en/products/trays-liners) - [POP Displays & Light Box Faces](/en/products/displays-signage) - [Heavy-gauge thermoforming](/en/capabilities/heavy-gauge-thermoforming) - [Thin-gauge thermoforming](/en/capabilities/thin-gauge-thermoforming) - [CNC machining & trimming](/en/capabilities/cnc-machining-trimming) - [Quality assurance](/en/quality/quality-assurance) - [Tooling & process engineering](/en/quality/tooling-process-engineering) - [Technical cleanliness](/en/quality/technical-cleanliness) [DISCUSS YOUR PROJECT](/en/quality/technical-cleanliness#contact) ## Contact [#contact] Discuss Your Project.
