Vehicle with Offset Angle

The present invention relates to a carrier with an offset angle, especially a vertical plane of a vertical frame and a sliding path of a slide table with an offset angle.

Press, in the entire information, communication, and consumer electronics industries, printed circuit boards are indispensable. The production process of printed circuit boards needs to go through the steps of developing process, electroplating process, film stripping process and etching process to make fine The wiring is used as a base for supporting electronic components and interconnecting circuits between components. Among them, the electroplating process is carried out by first clamping the printed circuit board in the electroplating rack, and then driving the electroplating rack to travel in the engineering equipment through the driving device, and immersing the printed circuit board in the electroplating tank and generating the anode Electrochemical action promotes the copper ions in the electroplating bath to be plated on the printed circuit board.

Second, the electroplating rack plays the role of conducting electricity and fixing the printed circuit board in the electroplating process, and the area where the circuit pattern is planned on the surface of the printed circuit board is called the effective area. On the contrary, the surface of the printed circuit board is not planned with circuits. The area of the pattern is called the invalid area. In the conventional way of fixing the printed circuit board, a plurality of fixing clips are arranged on the electroplating rack, and then the inactive area of the printed circuit board is clamped by the fixing clips, so that the printed circuit board is fixed on the electroplating rack. , and avoid clamping the effective area, but the current will be concentrated in the ineffective high current area, so the copper plating thickness of the effective area is not uniform, find the maximum and minimum copper plating thickness in the effective area, and use Formula: R value = maximum value - minimum value After calculation, the problem of a larger R value is usually obtained. Therefore, in view of the above-mentioned problems, the present inventor conceives a vehicle with an offset angle, which is the problem to be solved by the present invention.

The main purpose of the present invention is to provide a carrier with an offset angle, the vertical plane of the vertical frame and the sliding path of the slide table have an offset angle, and the printed circuit board can be slightly offset, so that the invalid areas overlap, The current passes through each inactive area to each active area, so the copper plating thickness of the active area is uniform, and the effect of reducing the R value of the copper plating thickness of the active area is improved.

Another object of the present invention is to provide a carrier with an offset angle, which uses lightweight plates to form a vertical frame, thereby improving the effect of reducing the weight of the carrier.

According to the features of the front cover, the offset angle is 1 degree to 5 degrees.

According to the feature of the front opening, the vertical frame is composed of a plurality of lightweight panels.

According to the feature of the front opening, a plurality of guide rods are arranged under the vertical frame.

According to the front-disclosed feature, the clamping element is a spring clip.

According to the aforementioned features, it further includes an electrode rod, and the electrode rod is arranged on the sliding table.

According to the aforementioned features, it further includes a plurality of printed circuit boards, the surface of the printed circuit board has an effective area and an ineffective area surrounding the effective area, and is matched with the carrier with the offset angle to form a plurality of, and each of the The clamping element can clamp the invalid area, so that the printed circuit board is slightly offset with the vertical frame. When the sliding table is at a predetermined conveying distance, the rear side of one of the vertical frames will be connected to the other vertical frame. The front sides are staggered so that one vertical frame slightly protrudes from the back side of the invalid area and the front side of the other vertical frame slightly protrudes from the invalid area to overlap.

With the help of the above-mentioned technical means, the present invention discloses that the vertical plane of the vertical frame and the sliding path of the slide table have the offset angle, which can slightly offset the printed circuit board, so that the inactive areas overlap and the current flows through the The ineffective area is to each of the effective areas, so the copper plating thickness of the effective area is uniform, and the vertical frame formed by the lightweight plate not only has the effect of reducing the R value of the copper plating thickness of the effective area, and enhances the effect , and the effect of reducing the weight of the vehicle is increased.
