CONVERTING IN AN ISO 9 CLEANROOM

Cleanroom production for adhesive tape and film solutions

Krückemeyer GmbH converts suitable adhesive tapes and technical films in an ISO Class 9 cleanroom. If particle control matters to your downstream bonding or assembly process, we coordinate the material, geometry, delivery format and inspection requirements with you.

TECHNICAL CLEANLINESS

What cleanroom converting can do for your component

Cleanroom converting means processing suitable materials in a controlled ISO Class 9 production environment. The cleanroom does not itself shape the material: cutting, die cutting, laminating or rewinding produces the required format. The controlled environment helps limit particle ingress during these operations.

For optically clear adhesive films used in display bonding, technical films for electronic components and shaped double-sided adhesive tapes, the environment can be part of the process design. Together, we establish which material and component requirements need cleanroom processing and which steps take place before or afterwards.

ISO 9 describes the room air class. It does not guarantee a defined particle cleanliness level for the finished part. Product cleanliness, inspection and documentation requirements must be agreed for the specific project.

YOUR CLEANROOM PROJECT

Step 01

Clarify the application and input material

Tell us about the component, intended application, input material, desired shape and technical cleanliness requirements.

Step 02

Check feasibility and the process

We assess material width, geometry, possible cleanroom processes and the required inspection and documentation.

Step 03

Agree the format and sample

We agree the structure, liner, handling and delivery format. A trial run can be arranged if needed; you test the sample in your application.

Step 04

Approval and production

After your approval, we produce the agreed format and inspect it against the agreed requirements.

CLEANROOM DECISION GUIDE

Question Documented scope Clarify for your enquiry
Which environment? ISO Class 9 cleanroom Specify room-air and product-cleanliness requirements separately
Which processing? Die cutting, slitting, laminating, combining layers, winding and rewinding are possible; laser cutti Assess the process route for the material and contour
Which dimensions? Material width up to 400 mm; die-cut parts up to 390 × 550 mm Assess component geometry, material structure and delivery format
Which inspection? Optical metrology and CPK analysis by agreement Agree measurement features, sampling and documentation

Check material and geometry for each project

08

WHAT TO INCLUDE IN YOUR ENQUIRY

Describe the application, the required component and why cleanroom processing is needed. Specify the input material or intended material structure, the contour and dimensions, the planned quantity and the delivery format.

A drawing or sample, information on the liner and application process, and your requirements for technical cleanliness, measurement and documentation are helpful. If you need a specific cleanliness assessment for the finished part, state this explicitly: the room class alone does not establish it.

CLEANROOM CONVERTING FAQ

Which materials can be converted in the cleanroom?

Suitable adhesive tapes, optically clear adhesive films and technical films are documented. Foam parts may also be possible after we assess the material and intended processing. The input material, geometry, dimensions and delivery format determine the route. Together, we establish which steps take place under cleanroom conditions and which requirements for the finished part need separate evidence.

Is a cleanroom-produced die cut automatically particle-free?

No. ISO Class 9 describes the controlled air in the cleanroom; it does not establish a specified particle cleanliness level for the finished part. If your component needs a defined cleanliness level, measurement methods, limits, sampling and documentation must be agreed for the project. Tell us about this requirement in your initial enquiry so that production and inspection can be planned accordingly.

Can Krückemeyer laser-cut films in the cleanroom?

No. Krückemeyer does not carry out laser cutting in the cleanroom. Cutting, die cutting, laminating, combining layers and winding suitable materials are among the available cleanroom processes. We assess which route suits your contour and material. A part cut outside the cleanroom should not be described as a cleanroom product solely because of its shape.

How are dimensions and inspection features agreed?

We agree dimensions, contour, material structure and delivery format using your drawing or sample. A material width of up to 400 mm and die-cut parts up to 390 × 550 mm are documented for the cleanroom; actual feasibility depends on the material and format. Optical measurements, inspection plans and CPK analyses are agreed when needed rather than included as a standard service.
