[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0023] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0025] Traditional electroplated edge strips are made of PCB copper-clad laminates and can only be used once. This results in high supply costs and high demand for edge strips, and production lines often experience material shortages.
[0026] In view of this, an embodiment of the present application provides a recyclable electroplated metal edge strip for PCB electroplating. By designing a conductive and recyclable edge strip to replace the copper clad laminate as the edge strip, the copper shedding phenomenon of the copper clad laminate edge strip and the breaking phenomenon of the edge strip can be avoided, thereby reducing the PCB electroplating cost.
[0027] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.
[0028] See also Figure 1 As shown, an embodiment of the present application provides a recyclable electroplated metal edge strip for PCB electroplating, including an L-shaped fixed section 5 and a retractable section 10. The retractable section 10 can slide relative to the L-shaped fixed section 5 to achieve retraction.
[0029] The L-shaped fixing section 5 has a side strip clamping groove 4 in the transverse section, which is used to be clamped by the electroplating fixture to distribute the electroplating current. The design of the L-shaped fixing section 5 and the side strip clamping groove 4 can increase the clamping area of the electroplating fixture and improve stability.
[0030] A guide pin 6 is provided on the vertical section of the L-shaped fixed section 5. The telescopic section 10 includes a guide rail 9, and a slot 8 is provided on the guide rail 9. The guide pin 6 is used to extend into the slot 8, and when the guide rail 9 slides through the slot 8 relative to the L-shaped fixed section 5 to be telescoped, the guide pin 6 is used for guidance. When the guide rail 9 is telescoped to a suitable position, the guide rail 9 can be fixedly connected to the L-shaped fixed section 5 by a fixing screw 7. With such a design, the effect of adjustable side strip length can be achieved.
[0031] As an example, the fixing screw 7 is used to detachably fix the guide rail 9 to the vertical section of the L-shaped fixing section 5 .
[0032] As an example, the fixing screw 7 is a butterfly screw.
[0033] As an example, the guide rail 9 is further provided with vertical grooves on both sides of the clamping groove 8, and the vertical section of the L-shaped fixing section 5 is protrudingly provided with a guide block for extending into the vertical groove.
[0034] The above-mentioned recyclable electroplated metal edge strips for PCB electroplating are made of stainless steel. The copper-tin electroplating layer can be stripped off in a nitrate hanging cylinder after electroplating to achieve the recycling of the electroplated metal edge strips, solving the problem of high cost, large demand and insufficient supply of the original copper clad laminate.
[0035] See also Figure 2 As shown, Figure 2 The schematic diagram of the application of a recyclable electroplated metal edge strip for PCB electroplating provided in the embodiment of the present application is shown. The electroplating fixture 3 is fixed on the electroplating target 1, and the electroplating distribution current is performed by clamping the recyclable electroplated metal edge strip 2 for PCB electroplating described in the above embodiment by the electroplating fixture 3.
[0036] In summary, the embodiment of the present application provides a recyclable electroplated metal edge strip for PCB electroplating, which is flexible to operate and recyclable, and can improve copper shedding of the edge strip of the copper clad board and other quality defects caused by the tin tank.
