Electronics & Adhesives: Peel Mechanics

The Physics of Adhesion

In the electronics industry, "Peel Strength" determines the user experience.

- Screen Protectors: Require a consistent "Low Peel Force" (easy to remove, no residue).

- Optical Adhesives (OCA): Require "High Shear Strength" to prevent bubbles.

Why 90° Peel? (ASTM D3330 Method F)

For rigid substrates (like glass screens), the 90° Peel Test is superior to 180°. It maintains a constant peel angle using a Floating Roller Fixture.

KHT WDL Series Advantage:

The WDL-05 captures the "Average Force" (ignoring the initial peak) to calculate the true peel strength in N/25mm. Its 0.5 Class Accuracy is vital for release liners where forces are often below 1N, requiring high signal-to-noise ratio sensors.
