Abstract

The embodiment of the present invention discloses a surface treatment method of a printed circuit board and the printed circuit board, wherein the surface treatment method of the printed circuit board includes: selecting an electroless nickel plating gold treatment method or The electroplating gold treatment method is to perform surface treatment on the connector of the printed circuit board; the surface treatment of the printed circuit board main body of the printed circuit board is carried out by using the electroless nickel plating gold treatment method and / or the first surface treatment method. The printed circuit board includes a printed circuit board main body and a connector. The surface treatment method of the connector is an electroless nickel-plated gold treatment method or an electroplating gold-plated treatment method selected according to the plugging frequency of the connector. The printed circuit board main body The surface treatment method is the chemical nickel-plating gold treatment method and / or the first surface treatment method. The embodiment of the present invention distinguishes the surface treatment methods of the connectors of the printed circuit boards with different insertion and extraction frequencies, thereby reducing the waste of resources.

Description

technical field [0001] The embodiments of the present invention relate to electronic technology, and in particular to a method for surface treatment of a printed circuit board and the printed circuit board. Background technique [0002] With the rapid development of telecommunications technology, various electronic products and components have emerged, and due to the increasingly fierce market competition, the structures and types of electronic products and components have become more and more diverse and complex. Among them, printed circuit boards (Printed Circuit Board; hereinafter referred to as: PCB) is used as a support for electronic components to provide electrical connections for various parts in electronic components. The interconnection between two PCBs is usually achieved through an edge connector commonly known as a gold finger, that is, inserting a gold finger on one PCB into a suitable slot on another PCB, such as a display card in a computer, The sound card, ...
