Peeling Blade/Edge: Thickness 0.5-2.0 mm

Q: How often should a peeling blade be replaced?

Typically every 50,000 to 200,000 cycles, depending on tape material and blade quality. Inspect regularly for wear, chipping, or dullness.

Q: What causes premature blade wear?

Abrasive tape coatings, misalignment, excessive tension, or using the wrong blade angle for the tape type.

Component Specifications

Definition

A specialized cutting component in cover tape peelers that precisely severs the adhesive cover tape from carrier tape during the automated feeding of surface-mount electronic components, ensuring component integrity and preventing contamination.

Working Principle

The peeling blade uses a sharp, precisely angled edge to initiate and propagate a clean cut along the seam between the cover tape and carrier tape. As the tape advances, the blade applies controlled shear force to separate the layers without damaging the components housed in the carrier pockets.

Materials

High-carbon tool steel (e.g., AISI D2, SKD11) or tungsten carbide, often coated with titanium nitride (TiN) or diamond-like carbon (DLC) for wear resistance and reduced friction.
