In high-precision industries such as solar energy, screen printing, lithium battery production, flexible electronics, and industrial roller manufacturing, even slight surface unevenness can directly affect product quality, production yield, and equipment lifespan.
Traditional flatness inspection methods are often:
Time-consuming
Dependent on operator experience
Difficult to quantify
Unable to visualize pressure distribution in real time
The S4 Surface Flatness Detection System (SFD) changes this by combining ultra-thin film pressure sensing technology with wireless data acquisition and intelligent software analysis.
The result is a portable, fast, and highly visual flatness inspection solution designed for modern industrial environments.
The S4 Surface Flatness Detection System (SFD) is a portable pressure distribution measurement system used to evaluate:
Scraper flatness
Roller contact pressure
Surface pressure uniformity
Mechanical alignment consistency
Dynamic pressure distribution during operation
The system wirelessly connects to a tablet or computer and displays real-time pressure mapping data through dedicated software.
It allows operators to quickly determine:
NG/OK status
Pressure concentration areas
Uneven contact points
Surface deformation issues
Installation or alignment problems
The SFD system provides intuitive pressure mapping through graphical software visualization. Operators can immediately observe pressure distribution changes during operation.
This significantly improves inspection efficiency compared with conventional feeler gauges or manual checking methods.
The collector adopts a 2.4GHz wireless communication design, allowing easy on-site inspection without complicated cable setups.
Advantages include:
Faster deployment
Greater mobility
Convenient field testing
Reduced wiring interference

The interface is intuitive and suitable for both engineers and production technicians.
The system operates by placing the thin-film pressure sensor between contacting surfaces.
When pressure is applied:
1. The sensor captures force distribution data
2. The collector acquires and transmits data wirelessly
3. The software converts the data into visual pressure maps
4. Operators analyze flatness and pressure consistency instantly
This process allows fast and repeatable industrial inspection.
One of the most common applications is in solar cell screen printing systems.
If the scraper is uneven:
· Printing pressure becomes inconsistent
· Silver paste distribution changes
· Solar cell appearance quality decreases
· Photoelectric conversion efficiency may decline
Traditional inspection methods often fail to detect small pressure inconsistencies.
Using the SF2825 thin-film sensor:
· The pressure distribution of the scraper is measured during printing
· Uneven pressure zones are clearly visualized
· Operators can immediately adjust scraper alignment
This helps optimize:
· Printing quality
· Process stability
Production efficiency
The SFD system can inspect:
· Rubber rollers
· Coating rollers
· Laminating rollers
· Conveyor rollers
It helps identify:
· Uneven wear
· Deformation

The system can evaluate:
· Fixture pressure consistency
· Clamping uniformity
· Surface contact quality
This is especially useful in precision electronics manufacturing.
Suitable for:
· Industrial automation systems
· Robotic pressure calibration
· Precision assembly equipment
