Description

Thin plate support fixture

The invention relates to a thin plate supporting jig, in particular to a thin plate process which can be processed by using existing process equipment.

With the trend of thin and light electrical products, the traditional thick plate circuit board (hard circuit board) has not conformed to the thickness specification, and the development of thin plates with thickness less than 250μm has gradually become the mainstream. In the traditional thick plate process, the thick plate loading device is used in various processes, which is to take three points of contact in the equipment, that is, the two ends and the intermediate support. If the thin plate is loaded into these devices, due to the mechanical strength of the thin plate Insufficient, after loading into the device, the thin plate will form a depression at the unsupported position, which will result in drug residue, poor product yield, and even the mechanical failure of the machine due to the depression.

In addition, further, new process equipment is also developing. The current method is to use a mechanical arm to grasp and stretch to support the thin plate. However, this support method has some disadvantages, for example, the use of a mechanical arm for gripping needs to be large. The area is reduced, and the use of the sheet is reduced. At the same time, the drug residue is more serious. In addition, in the manner of grasping the support, the size of the circuit pattern on the thin plate may be changed due to the stretching of the mechanical arm, and the new process is replaced. Equipment, the price is quite expensive.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a thin plate support jig for supporting a thin plate having a thickness of less than 250 μm. The thin plate supporting jig of the present invention comprises a main frame, a plurality of supporting mats, a plurality of connecting brackets, and at least two elastic supporting bodies, wherein the main frame, the supporting mats and the connecting racks are made of an acid and alkali resistant material. Into, and link together.

The main frame is a rectangular hollow frame with four side frames surrounding a hollow area. A plurality of support pads extend from the inner wall of the side frame to the hollow region, and a fixing pin is disposed on each of the support pads, and the position of the fixing pin corresponds to the fixing hole of the thin plate. A plurality of connecting frames are disposed at the grooves on the side frames. Each of the elastic support bodies is fixed by two of the connecting frames, and at least the two elastic supporting bodies are arranged at the same time, and the thin plate is elastically supported across the hollow region, and the elastic supporting body is linear and is resistant to acid. Made of an alkali elastic material.

The support pad includes a first portion and a second portion, the height of the first portion and the second portion being less than the thickness of the side frame. The first portion extends from the side frame, the second portion is coupled to the first portion, the height is higher than the first portion, and the fixed pin is disposed in the second portion.

Further, the thin plate supporting jig of the present invention comprises a plurality of penetrating regions which penetrate a partial region of the side frame to reduce the total weight of the thin plate supporting jig. In addition, during the electroplating process, a metal foil may be attached to electrically connect the thin plate to the thin plate supporting jig of the present invention.

The main feature of the present invention is that the support plate and the elastic support body support the thin plate, thereby avoiding the depression of the thin plate, and greatly improving the utilization rate of the whole thin plate, and also reducing the residual of the syrup and reducing the scratch during the process. Increased yield. Moreover, after the thin plate is fixed to the thin plate supporting jig of the present invention, the existing three-point supporting device is used to carry out various processes without purchasing a new jig, thereby greatly reducing the equipment cost, and the thin plate can be fixed in advance. It increases the flexibility of the process, reduces waiting time, and increases productivity.

Further, in the electroplating process, since the entire thin plate is simultaneously plated, the current density can be effectively dispersed, and when the metal material is used as the material of the thin plate supporting jig, it is provided by the metal material. The shielding effect can reduce the interference of the external magnetic field, and can expand the area through which the current flows to achieve a better uniformity of the current density.
