Abstract

Embodiment of the invention discloses a surface processing method for a printed circuit board and the corresponding printed circuit board, wherein the surface processing method for a printed circuit board comprises selecting electroless nickel immersion gold processing mode or electrogilding processing mode according to plug frequency of connectors on the printed circuit board, performing surfaceprocessing on the connectors of the printed circuit board. The printed circuit board comprises a main body of PCB and the connectors, the surface processing mode of the connectors is electroless nickel immersion gold processing mode or electrogilding processing mode selected according to plug frequency of the connectors, and the surface processing mode of the main body of PCB is electroless nickelimmersion gold processing mode and / or a first surface processing mode. The invention differentiates the surface processing modes of the connectors of PCB with different plug frequencies, which reduces 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, ...
