Abstract

The invention discloses a method and a device for manufacturing a single-side nickel-plated sheet. The method comprises the following steps: manufacturing a circuit, punching target position holes; knocking out target position holes and drilling holes; manufacturing electric resistance welding (characters); and shaping. In the invention, a drilling hole step is adjusted to be behind a copper-nickel alloy plating step so as to solve the technical problem of metal rings generated in plating. In the invention, the target position holes are arranged on a circuit pholin technological edge, and thetarget position holes are knocked out before the holes are drilled for not influencing the accuracy of the drilling holes; the punched target position holes are used for positioning the drilling holesso as to enable the holes to be more accurate and solve the technical problem of blind holes and the technical problem that the attractive appearance of the alloy surface is influenced by liquid medicine cross easily occurring in the plating. Compared with a dry film and a pholin, the invention has lower manufacture cost except for using a little more drilling tip.

Description

Technical field

[0001] The invention relates to the technical field of printed circuit boards, and in particular to a method and equipment for manufacturing single-sided electric nickel-gold boards. Background technique

[0002] As people know, printed circuit boards (PCBs) are used in almost all electronic devices we can see, from electronic watches and calculators to computers, electronic communication equipment, military weapon systems, etc., as long as there are integrated circuits For electronic components, the electrical interconnection between them requires PCB. Printed circuit boards are formed by providing conductive patterns for electrical connections between electronic components on an insulating substrate.

[0003] Electric nickel-gold board refers to one side of the printed circuit board used for the gold finger on the side of the board as a contact purpose, which can complete instant conduction under low voltage such as 2.5 volts, and can also be another type of repl...
