Problems solved by technology

However, due to the presence of the bracket, it cannot be held at the side end of the object to be processed, and the narrow pitch width is specified to prevent the current density from being too high, so this method is not preferable.
[0017] The invention described in Patent Document 5 proposes a method of suppressing deflection, in which the spraying of the plating solution is rectified so as to be parallel to the sheet product, but it is difficult to achieve non-contact with the swing prevention guide and the shielding plate.

Embodiment 1

[0036] pass Figure 1 to Figure 5 , specifically describe the embodiments of the present invention. Additionally, with Figure 6 and Figure 7The same components in the prior art described above use the same reference numerals.

[0037] first according to Figure 1 ~ Figure 3 , the embodiment of the invention described in technical solution 1 will be described. figure 1 It shows the state where the sheet product 1 as the object to be processed is suspended and clamped by the hanger 2 which is also used for power supply, and the state where the shielding plate 20 is installed on the bottom of the sheet product 1. The enlarged view of the mounting part of the plate 20, Fig. 2 (2) is the top view of Fig. 2 (1), image 3 is a diagram showing an example of deformation of the shielding plate.

[0038] The shielding plate 20 is formed of an insulating material with an open cross-sectional shape, which is a combination of a V shape and a square shape. The position of the sheet ...

Abstract

The plating method for sheet production comprises: using a hanging clamper to hold the top of PCB, conveying the sheet product in long electroplating slot with anodes on two sides continually for electroplating; wherein, the said hanging clamper can also be used supply power. This invention can ensure plating coat thickness evenly, and has no damage or bending effect.

Description

technical field [0001] The present invention relates to an electroplating method for sheet-like products such as printed circuit boards. In particular, the present invention relates to a method for plating sheet-like products in which the sheet-like In the state of the top of the product, the sheet-shaped product is continuously transported horizontally and in a row inside the elongated electroplating tank, and is electroplated at the same time. Background technique [0002] As a plating method for sheet-like products such as printed circuit boards, people have known an electroplating device in which the top of the sheet-like product is suspended and clamped by a hanger that is also used for power supply, and is placed horizontally and in series on a long strip. The sheet-like product is continuously conveyed inside the plating tank, and at the same time, it is plated (for example, refer to Patent Document 1 and Patent Document 2). In addition, there is known a plating trea...
