What is Surface Resistivity?

Measuring Surface Resistivity on plastic boxes is an important process for maintaining ESD standards in industrial factories. It helps protect sensitive electronic components and reduce electrostatic discharge risks. Specialized testing equipment and standards such as ANSI/ESD S20.20 are commonly used for accurate evaluation.

What is Surface Resistivity?

  • Electrical resistance on a material surface
  • Measurement unit: Ω/sq (Ohms per square)
  • Used to evaluate ESD protection capability
  • A critical parameter in ESD packaging systems
Main objective: Maintain surface resistivity within standard ranges to reduce defects and improve product quality.

Why is Surface Resistivity Testing Important?

Testing ensures that materials can effectively control electrostatic discharge, reduce production damage, improve product reliability, and comply with international industrial standards.

Surface Resistivity testing and ESD standards in industrial factories

ESD Standard Values Every Factory Should Know

Material TypeSurface Resistivity
Conductive < 10⁵ Ω/sq
Static Dissipative 10⁵ – 10¹¹ Ω/sq
Insulative > 10¹² Ω/sq
For ESD Plastic Boxes used in industrial factories, the recommended range is typically 10⁵ – 10⁹ Ω/sq

How to Check Surface Resistivity on Plastic Boxes

Required Equipment

  • Surface Resistivity Meter
  • Probe (2-Point / Ring Probe)
  • Testing Mat or Surface

Measurement Steps

StepDescription
1 Clean the surface of the plastic box
2 Place the probe on the surface
3 Turn on the measuring device
4 Read the displayed value (Ω/sq)
5 Compare the value with ESD standards
Important Notes:
- Avoid measuring in high humidity environments
- Test multiple points on the surface
- Regularly calibrate the measuring instrument

Comparison Table: Standard Plastic vs ESD Plastic

PropertyStandard PlasticESD Plastic
Surface Resistivity > 10¹² 10⁵ – 10⁹
ESD Protection ✖ No ✔ Yes
Suitable for Electronics ✖ Not Recommended ✔ Recommended
Price Lower Cost Slightly Higher

Standard Plastic

Suitable for general applications that do not require ESD control

Lower cost, but higher risk for electronic components

ESD Plastic

Designed to protect against electrostatic discharge in production environments

Helps reduce defects, improve product quality, and support electronics manufacturing

Case Study: Real SMT Factory

Problem

Using standard plastic boxes
PCB boards were damaged by electrostatic discharge

Solution

Changed to ESD Plastic Boxes
Checked Surface Resistivity values

Result

Reduced defects by 35%
Lower damage costs
Passed customer audits
