SMD Workshop ESD Control: More Than Just Anti-Static Flooring

In the construction of SMD micro-assembly clean rooms, a common misconception exists among many enterprises: they believe that simply installing anti-static flooring is sufficient to solve all electrostatic discharge (ESD) problems. This is a serious technical misunderstanding that can lead to poor product yield, equipment damage, and other serious consequences.

ESD control is a systematic engineering challenge, far more complex than just flooring. Below, we will comprehensively analyze the correct approach to ESD control in SMD workshops from the perspectives of ESD hazards, hardware control, and environmental control.

Electrostatic Breakdown: The Invisible Killer

SMD micro-assembly is extremely sensitive to static electricity. Voltages below 100V can damage chips. Many factories focus only on installing anti-static flooring during renovation while neglecting systematic grounding and environmental humidity control, which ultimately leads to:

• Severe dust attraction affecting product cleanliness
• High material rejection rates increasing production costs
• Unstable product first-pass yield rates making quality difficult to guarantee

The invisible hidden engineering often determines the visible product yield. ESD problems are insidious and cumulative—once damage occurs, it is often difficult to trace and recover.

ESD Control: Hard Standards

Keyao has strict construction standards for ESD control. Here are our core ESD control indicators:

These hard standards are not arbitrarily制定—they are based on 13 years of practical experience in clean engineering. The copper foil grid network ensures rapid and uniform electrostatic discharge. Independent grounding stakes guarantee grounding reliability, while permanent anti-static flooring avoids the maintenance issues associated with traditional conductive wax methods.

Inadequate Temperature and Humidity Control Renders Everything Futile

Humidity control is a crucial component of the ESD control system. Keyao strictly maintains workshop humidity at 45%-60% RH.

Why is this range so important?

• Humidity too low: Electrostatic accumulation, effective discharge becomes impossible
• Humidity too high: Solder paste absorbs moisture, causing solder splashing during reflow

Keyao employs high-precision constant temperature and humidity air conditioning systems with energy-saving variable frequency design. This ensures stable environmental parameters while avoiding energy waste and eliminating electricity cost "black holes."

Medical Grade Standards: Superior by Design

Guangdong Keyao applies the rigorous standards of medical clean engineering to industrial facility construction. We build SMD workshops with the same meticulous attention to detail used for ICU and operating rooms.

Keyao's Core Advantages:

• Dual patented technology + Building Electromechanical Installation Grade 1 Qualification

• 100+ renowned enterprise clients, including Inalfa Group, Hawley & Hazel, China Resources Sanjiu, and more

Our slogan: Guangdong Keyao—making your workshop pass any third-party inspection!

Planning an SMD Workshop? Get Your Plan First!

If you are planning an SMD workshop construction, it is recommended to obtain a professional technical plan before starting construction. A comprehensive ESD control system plan can help you:

1. Avoid the enormous costs of post-construction rework
2. Ensure passing inspections on the first attempt
3. Establish a stable and reliable production environment
