4a, 4b and 4c are schematic diagrams illustrating the operation of a container according to some embodiments of the present disclosure. The arrows in Figures 4a, 4b and 4c indicate the direction of fluid flow. As shown in FIG. 4 a, the wire 300 is adjacent to the opening 15, and fluid flows from the inlet 18 into the cavity 17. As shown in FIG. 4b, when the fluid fills the cavity 17, since the fluid continues to flow from the inlet 18 into the cavity 17, the fluid will flow into the cavity 23 through the opening 16 and the opening 21. Due to the principle of white effort, the fluid flowing through the opening 21 will form a slight vacuum at the opening 15. As shown in FIG. 4c, because the pressure difference between the opening 21 and the outside of the container 1 forms a fluid flow toward the cavity 23, the wire 300 is introduced into the container 1. The fluid entering the cavity 23 will flow from the container 1 to the outside through the opening 22.

FIG. 5a is a schematic diagram of an operation of a container 1 according to some embodiments of the present disclosure, in which the angle between the extension (or side wall) 141 and the normal to the opening 15 of the air inlet 10 Θ is 0 °. The fluid flowing from the opening 16 into the cavity 23 directly hits the multilayer structure 221, and bounces toward the opening 21, which not only offsets the fluid flow caused by the principle of white effort, but also pushes the wire 300 outward from the opening 15. FIG. 5b is a schematic diagram of an operation of the container 1 according to some embodiments of the present disclosure, in which the angle Θ between the extension (or side wall) 141 and the normal line of the opening 15 of the air inlet 10 is 90 ° . The fluids flowing from the opening 16 into the opening 15 collide with each other, resulting in a fluid flow outward from the opening 15 and a fluid flow from the opening 21 to the cavity 23. Not only cannot the gas flow generated by the white effort principle, but also the wire 300 from the opening 15 Push away.

Fig. 6a shows a wire collection box 60, and Fig. 6b shows a wire bonding machine 50 having the wire collection box 60 as shown in Fig. 6a. Because the diameter of the wire to be collected in the wire bonding operation is only about 0.6 to 1.28 mils (that is, 0.015 to 0.032 mm), it is not easy to detect when the wire falls out of the collection box. If this extremely light weight wire falls to the machine in operation following the airflow, it may pollute the operating environment and then damage the performance of the semiconductor package (such as generating a short circuit).

Adding a cover to the collection box prevents the wires from falling out of the collection box. FIG. 7 shows a lead collection box 70 having a cover 71. However, because the weight of the wire is too light, the wind pressure generated when the collection box lid is opened / closed may still lead the wire out of the collection box.

The above description describes the features of the embodiments to enable the skilled person to better understand the various aspects of the disclosure. Those skilled in the art can understand that the present disclosure can be used as a basis to complete methods and structures that can achieve the same purpose and / or have the same benefits as the above embodiments. These modifications, replacements, and changes do not depart from the spirit and scope of this disclosure.
