Double-face rack for vertical electroplating gold thread

Abstract

The invention relates to a double-face rack for a vertical electroplating gold thread and belongs to the technical field of vertical electroplating soft gold and electroplating hard gold surface processing. A fixing duck-tongue-shaped member is arranged on one end of a fixing rod of each of single racks, the other end of each of the fixing rods is connected with a vertical guiding rod, a positioning ring is respectively arranged at the middle end of each of the fixing rods and the bottom end of each of the vertical guiding rods, a plurality of electroplating clamping points are evenly distributed on each of the vertical guiding rod, two single racks are arranged in parallel, an upper sliding bar penetrates through the positioning rings on the two fixing rods and are fixed by first butterfly screws, and a lower sliding bar penetrates through the positioning rings on the two vertical guiding rods and are fixed by third butterfly screws. Based on prior racks and hanging plates, the design structure is modified, single-face electroplating clamping heads are changed to double-face electroplating clamping heads, the productivity is improved, and the water consumption and the electricity consumption are reduced. Plates are arranged through double faces, so that the time for one-time hanger taking and placing and one-time hanger width adjustment is saved. The production efficiency is greatly improved and rack usage amount is reduced.

Description

technical field [0001] The invention relates to a double-sided hanger used for vertical electroplating gold wires, in particular to a double-sided hanger used for electroplating gold in the Printed circuit board (hereinafter referred to as PCB) industry, which belongs to the surface treatment of vertical electroplating soft gold and electroplating hard gold field of processing technology. Background technique [0002] Vertical electroplating of soft gold and hard gold When processing PCB, PCB has completed all processes except surface treatment and molding process, and only needs to be processed to produce electroplated soft gold or electroplated hard gold to complete the required functional requirements. The vertical electroplating of soft gold and electroplating of hard gold requires the use of special electroplating fixtures to fix the board and form a closed path with the rectifier circuit of the equipment before electroplating. [0003] The pinch point design of the go...

AI Technical Summary

Problems solved by technology

[0003] The pinch point design of the gold-plated hanger is single-sided, that is, only one board can be clamped at a time, while the nickel-plated gold-plated rectifier with vertical gold-plated lines is generally designed on both sides, because of the different PCB shapes, for some Sometimes there is only one side of the PCB board to be plated. In this case, if the old electroplating rack is still used, and each rack is only loaded with one board at a time, the utilization rate of the equipment will decrease, resulting in the idleness of the electroplating rectifier equipment. , affecting production efficiency, increasing the unit consumption of water and electricity, and at the same time causing idle anodes to be plated as cathodes, resulting in unnecessary waste and quality problems
