Description

Magazine for Semiconductor Manufacturing Process {Magazine using in Semi-conductor Production Process}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magazine used for transferring a PCB or leadframe in a semiconductor manufacturing process, and more particularly, to a magazine that can stably transport a PCB or leadframe housed in a magazine without spilling. .

The semiconductor manufacturing process is roughly divided into FAB process, assembly process, and inspection process. For example, even in the assembly process, sawing, die attach (D / A), die attach curing (D / A curing), It consists of several steps such as wire bonding, plasma treatment, molding, and post curing. In this process, the PCB or lead frame on which the semiconductor chip is mounted is sold in dozens of units. It is stored in the excitation and transported.

1 is a perspective view of a magazine in which a PCB or lead frame is supported by a magazine cover in the most typical conventional magazine.

A plurality of seating grooves 111 in which PCBs or lead frames 200 are accommodated on both sides of the inner surface of the magazine body 110 having a space therein are formed at a predetermined interval, and the magazine body 110 The front and rear end portions of the magazine cover 120 for supporting the PCB or lead frame 200 accommodated in the magazine body 110 so as not to escape to the outside of the magazine body at the time of transportation of the magazine 100 are removable. It is installed.

Meanwhile, guide grooves 112 are formed on the outer sides of the front and rear end portions of the magazine body 110, respectively, and both sides of the magazine cover 120 are formed on the respective guide grooves 112 of the magazine body. Guide protrusions 121 are bent and formed to be coupled, guided, and moved.

In addition, the magazine cover has an opening 122 formed to view the PCB or lead frame housed in the magazine main body 110, thereby observing the inside and forward and rearward directions of the PCB or lead frame and manufacturing process. You can check the progress.

When one of the semiconductor manufacturing processes is completed and the PCB or lead frame 200 is to be transferred to the next process, the PCB or lead frame 200 is stored in each seating groove 111 formed in the magazine body 110. Then, the removed magazine cover 120 is coupled to the magazine body 110 again and transferred to the next process.

The die attach cure process, the plasma treatment process, and the post-curing process of the semiconductor manufacturing process are performed in a state in which the PCB or the lead frame 200 is stored in the magazine 100. Vent holes 113 are formed on both sides of the main body 110 so as to facilitate heat transfer.

However, the magazine 100 is not stable because the combination of the magazine main body 110 and the magazine cover 120 is shaken during transfer or collapsed by a worker's mistake when the received PCB or lead frame 200 is There is a risk of spillage, and when you want to take out the PCB or lead frame to perform each step process, the magazine cover 120 must be completely removed.

In particular, even when the loading or unloading of the PCB or the lead frame 200 is automated, the operation of coupling and removing the magazine cover 120 to the magazine body 110 by manual operation is performed by hand. Should.

Thus, the PCB or lead frame housed in the magazine body by two support bars installed so as to rotate outwardly at one of the two corners of each of the front and rear ends of the magazine body in place of the magazine cover 120. Supported magazines have been developed and used.

FIG. 2 is a perspective view of a magazine in which a PCB or lead frame is supported by a support bar, and FIGS. 2A and 2B illustrate a PCB or lead frame 200 accommodated in a magazine body 110 by a support bar 130. Figure 2b shows a supported state (locked state), Figure 2b is a state in which the support bar 130 is folded (open state) to take out the PCB or lead frame 200 accommodated in the magazine body 110 to the outside It is shown.

The mechanism by which the support bar 130 is opened and closed is described in more detail using FIGS. 2A and 2B.

The support bar 130 is connected to the upper rotary shaft 131a and the lower rotary shaft 131b installed in a state corresponding to each other at one edge of the outer side of the upper and lower sides of the magazine body 110, and 270 ° from the outside of the corners thereof. Rotation achieves a locked state (FIG. 2A) or an open state (FIG. 2B).

The support bar 130 is rotated by a lever 132 that rotates 90 ° from the upper end of the magazine body 110. The gear bar is formed around the gear shaft and the upper rotating shaft 131a. The gear is engaged and the movement is transmitted.

On the other hand, the lever 132 has a fastener 133 is fixed to the locking claw 134a in the locked state (FIG. 2A), and fixed to the opening brace 134b in the open state (FIG. 2B). , 134b are connected to each other inside the upper plate of the button 135 and the magazine body 110 (not shown), and when the button 135 is pressed, two latches 134a and 134b are recessed to free the lever 132. It is movable, and when the button is not pressed, it protrudes out, and when it is fitted to the fixture 133 of the lever in this state, it is possible to fix the locked state (FIG. 2A) or the open state (FIG. 2B).

The magazine, which is supported by the support bar by the PCB or the lead frame, can be transported to the PCB or lead frame very stably since the support bar is never opened unless the button is intentionally pressed, by pressing the button 135 and pressing the lever 132. If the rotating operation by the machine has the advantage that the operation of inserting and removing the PCB or lead frame in the magazine body 110 can be automated.

However, there is a disadvantage that the structure is very difficult to manufacture due to the complex structure, the probability of failure due to the complex structure is high, the price is high, and the cleaning is difficult when the magazine is dirty by repeated plasma treatment.

An object of the present invention is to provide an economical magazine that can stably support the PCB or lead frame, the transport operation can be made safely, the structure is simple, easy to manufacture and manipulate, as well as easy to clean when dirty.
