1. What is a cleanroom LED panel light?

A cleanroom LED panel light is a type of lighting fixture designed for environments with strict control over dust particles, bacteria and static electricity - such as cleanrooms in electronics, pharmaceuticals, food factories and especially SMT zones.
Unlike ordinary domestic LED lights, cleanroom LED panels feature a sealed structure, smooth flat surface and use anti-static or dust-resistant materials. This design helps prevent dust generation, is easy to clean, and does not compromise the cleanliness of the working environment.
In cleanrooms, LED panel lights not only ensure adequate illumination for equipment operation and precise manipulation, but also contribute to maintaining ISO cleanliness levels thanks to their ability to minimize particles released into the air.

Role in SMT areas

In SMT (surface‐mount technology) areas - where parts are mounted onto printed circuit boards (PCBs) - incredibly stable and precise lighting is required. Any fluctuation in brightness or color rendering index (CRI) can cause deviations during inspection, soldering or assembly.
Therefore, cleanroom LED panel lights play a crucial role in:

  • Providing uniform light, no glare, supporting quality inspection of solder joints

  • Minimizing dust or static discharge risk, preventing circuit shorts or micro-circuit damage

  • Maintaining stable working conditions, reducing manual error in the SMT production line

Technical requirements in SMT zones

To meet the specific production environment of SMT, LED panel lights must satisfy certain technical requirements:

  • Sealed design, dust protection (IP40 or higher)

  • Use anti-static materials, ensuring safety for sensitive micro-circuits

  • CRI ≥ 80, for accurate light rendering

  • Stable correlated color temperature (CCT), typically 5000 K to 6000 K, to reduce eye fatigue during long shifts

2. Why does an SMT area need dust-proof dedicated LED panel lights?

The SMT production environment is extremely sensitive to dust and electrostatic discharge (ESD).
In SMT zones - where main steps include solder paste printing, component placement, reflow soldering - precision is extremely high and components are small, thin and sensitive to external factors.
In this environment, fine dust or static electricity can seriously affect product quality:

  • Dust may adhere to the PCB, causing soldering defects or short circuits

  • Static discharge may randomly occur (ESD), damaging ICs, chips, transistors…
    Thus, lighting systems - including LED panel lights - must also meet cleanroom standards: no particle generation, no static discharge, and no lighting fluctuation.

The harms when using non-standard lights

Using inappropriate LED lights in SMT areas can lead to many risks:

  • Particle generation from the light surface or micro-gaps, contaminating the cleanroom environment

  • Uneven lighting or wrong color temperature, causing inspection errors and increasing defect rates

  • Lack of static control, increasing risk of component damage during handling
    Moreover, lacking proper technical standards can make maintenance and replacement difficult and impact production schedule.

Required standards to comply

To ensure suitability for SMT production, cleanroom LED panel lights must comply with some standards:

Standard Purpose
ISO Class (ISO 14644) Ensures the light is suitable for the cleanroom class (Class 7 – Class 5)
RoHS Ensures no harmful substances, environmentally friendly and safe for SMT production
Industrial lighting standards (CRI, CCT) Ensures stable illumination, high color rendering for accurate inspection
ESD standard Reduces risk of static discharge impacting sensitive micro-circuits

Choosing the right cleanroom LED panel light not only helps maintain the production environment’s standards, but also enhances product quality and reduces defects in the SMT line.

3. Criteria for selecting LED panel lights for SMT cleanrooms

When choosing LED panel lights for SMT production areas, companies need to consider not only illumination factors, but also cleanliness, stability and compatibility with industrial standards. Below are important criteria:

Meeting cleanroom ISO standards: LED panels used in cleanrooms must fulfil ISO 14644-1 - the international standard governing particle counts in the air for each cleanroom class. The light must be designed such that:

  • No particle generation during usage
  • No disruption to cleanroom air flows (HVAC, HEPA)
  • Suitable for cleanroom classes from Class 7 to Class 5 - commonly applied in SMT areas

Sealed, dust- and bacteria-proof design: The structure must ensure full sealing (continuous gasket, no gaps) to:

  • Prevent dust penetration into the lamp and shorts
  • Avoid bacteria accumulation and allow easy cleaning
  • Improve maintenance efficiency and reduce downtime when changing lamps

High color rendering index (CRI), stable illumination: SMT areas require LED panel lights with CRI of 80 or higher, to:

  • Clearly distinguish component colours and solder joints
  • Minimize errors during visual inspection

Additionally, the illumination must be flicker-free and brightness stable, especially important for automated optical inspection (AOI) cameras.

Surface materials: anti-static mica or tempered glass: The diffuser panel should use:

  • Anti-static mica: reduces ESD generation, safe for PCBs
  • Tempered glass: protects the LED chips inside, increases lamp lifespan

These materials also help achieve uniform light distribution, no glare, suitable for long hours of continuous operation.

Long lifespan, energy-efficient, easy maintenance: A good cleanroom LED panel light should have:

  • Lifespan ≥ 30,000 hours, reducing replacement cost
  • High luminous efficacy (≥ 100 lm/W), saving energy for the factory
  • Module or separate driver design, easy to replace components when needed

Selecting the correct LED panel not only ensures the SMT production environment meets standards, but also helps optimize operational cost and improve production efficiency.
