## Abstract

A device (2) having at least one connecting element (24, 26) for fastening a component (4) to, respectively for detaching it from a component carrier (6) using adhesive bonds; a mechanical peeling device (8) being provided for breaking the adhesive bonds. Also a method for fastening a component (4) to, respectively for detaching it from a component carrier (6).

## Claims

### Claim 1

A device for attaching a component to a component carrier, respectively for detaching the component from the component carrier, the component fastenable via at least one connecting element to the component carrier using adhesive bonds, the device comprising:
a mechanical separator for breaking the adhesive bonds, the separator having a sliding element displaceable relative to the component carrier and the component; wherein the component carrier has at least one limit stop for positioning the connecting element.

### Claim 2 (depends on 1)

The device as recited in claim 1 wherein on a component carrier side, the separator has a wedge-shaped sliding element guided within a guideway.

### Claim 3 (depends on 2)

The device as recited in claim 2 wherein on both sides of the guideway, a pedestal is configured on the component carrier to accommodate the connecting element.

### Claim 4 (depends on 1)

The device as recited in claim 1 wherein the sliding element has at least one jaw open in the sliding direction.

### Claim 5 (depends on 1)

The device as recited in claim 1 further comprising distance elements for adjusting an optimal adhesive gap width.

### Claim 6

A device for attaching a component to a component carrier, respectively for detaching the component from the component carrier, the component fastenable via at least one connecting element to the component carrier using adhesive bonds, the device comprising:
a mechanical separator for breaking the adhesive bonds, the separator having a sliding element displaceable relative to the component carrier and the component; and
distance elements for adjusting an optimal adhesive gap width.
