SMD Clean Room Construction: A Complete Guide for Beginners
A comprehensive SOP guide to SMD clean room construction covering 10 steps from needs analysis to final acceptance. 13 years of professional experience from Guangdong Keyao.
In the electronics manufacturing industry, constructing an SMD micro-assembly clean room is a complex systems engineering challenge. Many business owners encounter pitfalls during their first construction project, leading to issues such as substandard cleanliness, excessive energy consumption, and failed ESD protection.

Today, Guangdong Keyao leverages 13 years of professional experience to provide you with a detailed breakdown of the complete SOP process for SMD clean room construction, helping you avoid common pitfalls and create a high-quality clean production environment.
Requirements Analysis and Design Planning
A Quality Workshop Is "Calculated"
One of the biggest concerns for many business owners is whether electricity costs will become a bottomless pit after completion.
In fact, an excellent design plan begins controlling costs from the requirements analysis phase. Keyao's design planning phase includes the following core work:
- Load Calculation: Precise calculation of SMT equipment heat output, ensuring appropriate air conditioning sizing to avoid underpowered systems or wasteful over-specification
- Personnel and Material Flow Separation: Scientific planning of personnel and material pathways to reduce cross-contamination and improve cleanliness levels
- Temperature and Humidity Lock: 23±2°C, 45-65%RH — critical parameters for ensuring solder paste printing yield

A professional floor plan clearly shows the flow of personnel and material channels, as well as the scientific layout of return air columns. These details determine the smoothness of workshop operations and energy efficiency.
Enclosure Structure Construction
No Dead Corners, No Dust Generation
SMD clean rooms have extremely high cleanliness requirements. Any construction detail can become a dust accumulation dead zone. Keyao strictly executes the following standards during enclosure structure construction:
- Handmade Magnesium Oxide Rock Wool Panels: Class A fire resistance, high strength, dust-free, long service life
- R-Corner Treatment: Wall corners and floor corners all use rounded transitions, not only easy to clean but also GMP-compliant
- Sealant Technology: Neutral mildew-proof silicone used for tight sealing, preventing air pressure leakage

The treatment of R-corners may seem simple, but it tests the professional standards of the construction team. Rounded transitions at wall corners, ceiling corners, and floor corners effectively avoid dust accumulation and reduce cleaning difficulty — details that cannot be overlooked in clean room construction.
Floor Anti-Static Engineering
The "Lifeline" of SMD Workshops
For SMD micro-assembly workshops, floor anti-static engineering is the "lifeline." Electrostatic breakdown of chips means product rejection — a scenario no electronics factory owner wants to face.
Keyao's floor anti-static process includes the following key elements:
- Hidden Engineering: Full installation of conductive copper foil grid forming a complete static discharge channel (an area where many low-cost projects cut corners)
- Surface Material: 2.0mm/3.0mm anti-static PVC flooring with constant resistance in the $10^4-10^6\Omega$ range
- Self-Leveling Process: High-strength self-leveling base with flatness controlled within 2mm, ensuring stable operation of SMT pick-and-place machines

The installation of the copper foil grounding grid is the core of anti-static engineering. It can rapidly conduct static electricity away, protecting sensitive electronic components. The quality of this hidden engineering directly relates to product yield rates.
Purification System and Commissioning
Applying Medical Grade Standards to Industrial Applications
One of Keyao's core advantages is applying medical clean engineering standards to industrial workshop construction. During the purification system and mechanical commissioning phase, we adopt:
- Three-Stage Filtration: Primary + Medium + High Efficiency (HEPA), filtering 99.99% of 0.5μm particles
- Insulation Technology: Seamless wrapping with rubber-plastic insulation cotton, eliminating condensation drip (a major taboo in SMT workshops)
- Energy-Saving Variable Frequency: Automatic air volume adjustment based on workshop load, saving electricity means saving money

Neat and uniform duct layout is not only aesthetically pleasing but also ensures uniform air distribution, improving purification efficiency. Meanwhile, energy-saving variable frequency design effectively reduces operating costs, creating long-term value for you.
Testing and Acceptance
Data Speaks, Pass on First Attempt
The final acceptance phase is the key moment to verify construction results. Keyao lets data speak, ensuring your SMD workshop passes inspection on the first attempt.
