Edge separation equipment and operating method thereof

An edge separation equipment acting on for a carrier and a circuit board, wherein the carrier and the circuit board are attached by an interface layer on the carrier, and the edge separation equipment is capable of separating an edge of the circuit board from an edge of the carrier by separating the circuit board from the interface layer on the carrier, the edge separation equipment comprises:

• a platform having a supporting surface, wherein the carrier or the circuit board is placed on top of and aligned to the outside edge of the supporting surface;
• a supporting device installed at a side of the platform;
• and
• a wind knife device installed on the supporting device, inserted into and applies an air jet within the edge of the carrier and the edge of the circuit board, so as to form an edge separation width, equal to the amount of insertion of the wind knife device, between the carrier and the circuit board, wherein the supporting device includes:
• a slide rail, the wind knife device being on the slide rail along a direction, the insertion of the wind knife device into the edge separation where the width between the edge of the carrier and the edge of the circuit board, equal to the amount of the insertion of the wind knife device, being maintained, the direction being parallel to a side of the circuit board;
• and
• a connecting frame attached the platform and the slide rail sits on the connecting frame.
