Title:
MANUFACTURING METHOD AND APPARATUS FOR ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2023/207349
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of photovoltaic device manufacturing. Disclosed are a manufacturing method and apparatus for an electronic component. The method comprises: placing a semiconductor device in a cathode region and driving the semiconductor device to move in the cathode region, and also connecting a wire plating roller to a power supply and driving the wire plating roller to rotate, such that a conductive portion in the outer circumferential direction of the wire plating roller plates a metal wire on a surface of the semiconductor device in a movement direction thereof, wherein the conductive portion comprises a wire plating region and a deplating region, an anode is arranged on an outer side of the deplating region, and the anode is electrically connected to a positive electrode of the power supply by means of the connective portion in the deplating region; and the cathode region in which the semiconductor device can be placed is provided on an outer side of the wire plating region, and the semiconductor device is electrically connected to a negative electrode of the power supply by means of the conductive portion in the wire plating region. By means of the present invention, the efficiency of the wire plating on a surface of a semiconductor device can be improved, and the uniformity of a metal layer on the surface of the semiconductor device such as a silicon wafer or a battery cell can be improved, thereby improving the efficiency of production of an electronic component.
