The present invention relates to a reel to reel plating system, and more specifically, each of the detailed processing units constituting the pre-processing unit, the plating process unit, and the post-treatment unit for plating the connector and the plate are independent. The present invention relates to a reel-to-reel plating system that can be modularized into a single process unit and can be configured to freely arrange each detailed process unit according to the connector and the metal to be plated.

The reel used in the semiconductor manufacturing process performs a conducting function of electrically connecting a circuit of an external device while supporting and mounting a connector and a plate. A strip-shaped conductive metal sheet is formed by using a mold and a press. It is made by continuously punching into the designed shape.

In addition, the connector and plate are plated with various conductive metals to improve electrical properties and durability, and such plating is continuously plated in a state in which a strip-shaped thin lead frame is wound in a reel form. By feeding into the system.

FIG. 1 is a configuration diagram showing a plating process of a general reel-to-reel plating system, in which a connector and a plate W are continuously supplied by a feed roller 1 wound in a reel form, and a connector and a plate W are supplied. To be supplied to the plating system (4) via an accumulator (3) having a plurality of adjusting rollers (3a) arranged in a zigzag horizontally to adjust the feed rate and tension of the The plated connector and plate W are wound on the take-up roller 5 by repeatedly or continuously performing degreasing, polishing, cleaning, plating, and activation processes while passing through (4).

2 shows an example of a conventional configuration of the plating system 4 in the plating process as described above, and includes an ultrasonic degreasing unit a1, a first electrolytic degreasing unit a2, a second electrolytic degreasing unit a3, and chemical polishing. A pretreatment step (a) comprising a unit (etching) a4 and an acid cleaning unit a5, a first nickel plating unit b1, a second nickel plating unit b2, a cleaning unit b3, and a third Nickel plating unit (b4), fourth nickel plating unit (b5), cleaning unit (b6), activation unit (b7), gold flash unit (b8), first thickness plating unit (b9), second thickness plating unit (b10), washing unit b11, third thickness plating unit b12, activation unit b13, first stone plating unit b14, second stone plating unit b15, and cleaning unit b16. Plating process step (b), pure water cleaning unit (c1), discoloration prevention unit (c2), after-treatment unit (c3), cleaning unit (c4), pure water cleaning unit (c5), air knife unit (c6), It is comprised by the post-processing process part (c) which consists of a drying unit (c7).

The arrangement and number of batches of the detailed processing units a1 to a5, b1 to b16 and c1 to c7 of the pretreatment step (a), the plating step (b) and the post-treatment step (c) as described above are plated. It is set in various ways according to the type of connector and plate to be plated and the metal to be plated.

However, the conventional reel-to-reel plating system uses the detailed processing units (a1 to a5, b1 to b16, c1 to c7) constituting each processing step (a, b, c) for plating a specific connector and plate. Since the batch order and the number of batches were set integrally, it was very difficult to separate or additionally install each of the detailed process units a1 to a5, b1 to b16, c1 to c7, and thus it was virtually impossible to modify the plating system.

Therefore, if the type of connector and plate is different or the metal to be plated is different, a new plating system must be constructed accordingly, which increases the installation cost and economically requires a large space. There was a difficult problem.

In addition, since the entire plating system is managed by one control system, the electric system and the piping system are complicated, so there are many difficulties in resetting or rewiring the program at the time of modification, and many supporting frames are used to integrate the entire plating system configuration. There is a problem that the facility becomes more complex.

In addition, when an abnormality occurs in any one of the detailed process units, it is not easy to check whether there is an abnormality, and the productivity is lowered because the entire plating system must be stopped until the repair of the abnormal detailed process unit is finished. I had a lot of problems.

The present invention is to solve the above problems, its purpose is to modularize the detailed processing unit of each processing unit for the plating of the connector and the plate to operate independently of each other, for the plating of the specified connector and plate By changing or repositioning the detailed process unit with the plating system set up, the plating process can be performed even if the types of connectors and boards are different or the metals to be plated are different, and for plating various types of connectors and boards. There is no need to configure multiple systems, which provides an economical reel to reel plating system.

In addition, by allowing each detailed process unit to operate as an independent control system, the electrical system and piping system can be simplified, and the system does not need to be reset or rewired when replacing or relocating the detailed process unit. Can be operated efficiently, and in case of abnormality of each detailed process unit, only the corresponding detailed process unit can be replaced for easy maintenance, and there is no need to stop the operation of the entire plating system to repair the detailed process unit. To provide a reel to reel plating system that can improve the.

The present invention for achieving the above object, a degreasing unit, a polishing unit, pre-processing unit consisting of a cleaning unit; A plating process unit comprising a plating unit, a cleaning unit, and an activation unit; And a post-treatment processing unit consisting of a cleaning unit, a discoloration preventing unit, a post-treatment unit, an air knife unit, and a drying unit in series, wherein each pretreatment process unit, plating process unit, and post-treatment process are performed. Each of the detailed processing units constituting the unit is modularized to be operated independently, and is characterized by a reel-to-reel plating system configured to replace and rearrange each detailed processing unit.

Hereinafter, a preferred embodiment of a reel to reel plating system according to the present invention will be described in detail with reference to the accompanying drawings.

Therefore, it is possible to remove or add detailed processing units (A1 to A5, B1 to B16, C1 to C7) of each processing step (A, B, and C) according to the type of connector and plate or the connector and plate to be plated. Therefore, the plating process may be performed on the plating of the connector and the plate as well as the plating of the specified connector and the plate.

In addition, since each detailed process unit (A1 to A5, B1 to B16, C1 to C7) can be operated independently with the control system provided in each, it is possible to simplify the electrical system and piping system of the entire plating system. When replacing or relocating any one or more detailed process units, there is no need to reconfigure or rewire the program. If an error occurs in any one or more detailed process units, only the corresponding detailed process unit is separated and the same function is performed. It is easy to maintain and replace by the detailed process unit of, and the time to stop the operation of the whole plating system can be shortened and productivity can be improved.

The present invention is not limited to the embodiments described so far, and the detailed processing unit (A1) of the pretreatment step (A), the plating step (B) and the post-treatment step (C) for the plating of the connector and the plate material ~ A5, B1 ~ B16, C1 ~ C7) can be variously changed or arranged according to the type of the connector and plate or the metal to be plated, and those skilled in the art within the scope of the technical idea and utility model registration claims of the present invention Various changes, modifications, or substitutions may be made thereto, and such embodiments are to be understood as being within the scope of the present invention.
