Decoding Raised Floors in Cleanrooms for Electronics Manufacturing Plants

In the era of high-tech manufacturing, electronics factories not only require modern production lines but also cleanroom-compliant environments. One of the core elements that help maintain these conditions is the raised floor in cleanrooms. This article will help you decode raised floors in cleanrooms for electronics factories, from structure and functions to installation standards.

Why are raised floors needed in electronics factories?

In environments producing electronic components, even the tiniest dust particles or static electricity can damage products. Raised floors not only enable proper airflow circulation but also:

• Conceal electrical wiring to prevent disorder and damage.
• Create space for the underfloor air return system.
• Support ESD devices to prevent static and protect components.

Therefore, constructing raised floors in cleanrooms is a must in high-tech factories.

Structure of raised floors in electronics factories

A standard raised floor system includes:

1. Floor panels

Usually Galvanized Steel raised floor panels or HPL raised floors, which have the following features:

• Good load-bearing capacity.
• Moisture and chemical resistance.
• Flat surface, easy to clean dust and debris.

2. Support frame and pedestals

Made from galvanized steel or stainless steel, adjustable in height. This is the main load-bearing component and determines the floor's stability.

3. Underfloor electrical and grounding system

Includes:

• Concealed wiring.
• Grounding wires under the floor connected to the anti-static system.
• EPA static control devices installed underneath to ensure safety for all electronics.

Do raised floors affect air filtration efficiency?

The answer is YES. Raised floors help:

• Create a buffer zone for air to move from ceiling to floor, then be returned to the central filtration system.
• Stabilize airflow in a laminar pattern, preventing reverse dust flow into production areas.
• Enhance filtration efficiency, contributing to maintaining ISO 14644-1 and GMP EU cleanroom standards.

Common types of raised floors today

Depending on usage and technical requirements, the following types of raised floors are available:

1. High-tech raised floors

   Used in electronics factories, fully integrated with wiring, gas regulation, and ESD systems.

2. GMP-compliant raised floors

   Applied in high-tech pharmaceutical and food manufacturing facilities.

3. Light-duty raised floors

   Used in office areas without heavy equipment.

Cleanroom raised floor standards

A compliant raised floor must meet the following:

• Minimum load capacity of 1000kg/m².
• No particle generation from collisions or prolonged use.
• Easy to clean and free from residue retention.
• Materials must not chemically react with cleaning agents.
• Surface resistance must meet ESD cleanroom requirements.

???? To meet these standards, many factories choose raised floors from Huiya Floor, a reputable brand specializing in cleanroom flooring.

How to install raised floors correctly

Step 1: Detailed design

Includes layout of electrical wiring, panels, air extraction zones, and air return locations under the raised floor.

Step 2: Prepare the base floor

Must be perfectly level, clean, and dry.

Step 3: Fix support frame and pedestals

Use laser levelers. Each pedestal should have an anti-slip base plate.

Step 4: Install floor panels

Ensure tight joints with no dust-trapping gaps.

Step 5: Check grounding

Ensure resistance is <10⁶ ohm, enabling effective ESD equipment operation.

???? Refer to the article “GMP-Compliant Cleanroom Installation Process” for more detailed steps.

How to test raised floor load capacity

Since heavy equipment like control cabinets and robots move over the floor, it must be strong and non-deformable.

Testing procedure includes:

• Apply 1000–1500kg load to the center of a panel for 24 hours.
• Observe sinking, sagging, or deformation.
• Measure the force required to cause failure (crush load test).

Differences between cleanroom and office raised floors

Is it mandatory to use raised floors in electronics factories?

Yes, if:

• The factory produces micro-components like chips, ICs, displays.
• Cleanroom level ISO 7 or higher is required.
• SMT lines or automation robots are installed.

Not mandatory, if:

• The factory performs simple machining with no strict dust/static requirements.

However, to align with “smart factory” trends, most new plants are designed with high-tech raised floors from the start.

Optimal raised floor solutions for electronics factories

To optimize cost and performance, businesses should:

• Select flooring suitable for equipment, machine density, and foot traffic.
• Routinely inspect and maintain grounding, frames, and panels.
• Prefer products with international certifications such as ISO, FDA.
