Pressure Sensitive Film for Precise Pressure Mapping

Pressure Sensitive Film

Pressure Sensitive Film (also called pressure indicating or Prescale film) reacts to applied pressure by bursting microcapsules that cause a red color to develop. This gives immediate, high-resolution snapshots of force distribution between surfaces. It’s favored in industries like mold design, SMT assembly, gasket inspection, and display lamination, where precision contact pressure is critical.

Unlike wired or digital sensors, this film needs no calibration or power—just cut, apply, press, and visually inspect the result.

Specifications

Key Benefits

• Immediate visual results—no instruments, no delay

• Broad pressure detection from ultra-low to ultra-high

• Adapts to contours—excellent for curved or tight contact zones

• High-temp capable—works in heat-press environments (e.g., SMT reflow)

• Clean and disposable—ideal for controlled environments

Typical Applications

• Mold alignment & validation during tooling setups

• Semiconductor packaging—ensure even die bonding

• Display lamination for LCD/OLED panels

• SMT press or roller checks in assembly lines

• Gasket and sealing inspections in precision instruments

How to Use

1. Cut the film to size and align the coated sides together

2. Place between the contacting surfaces

3. Apply the required pressure

4. Peel off the film to reveal the red map

5. Scan or photograph for records or analysis

6. Dispose—no cleaning or residue left behind
