Description

Technical Field

[0001] The utility model relates to the technical field of discrete device processing, in particular to a discrete device circuit processing and manufacturing device. Background Art

[0002] There are two major branches in the semiconductor industry: integrated circuits and discrete devices. In the manufacturing of discrete semiconductor devices, after the copper frame is bonded, bonding, also known as wire bonding, is required to physically connect the circuit chip to the pin. Aluminum wire or copper wire is generally used. In actual applications, the circuit chip is generally placed in a placement frame on the copper frame conveying mechanism of the bonding machine to achieve fixation. However, since the size of the placement frame is fixed, it is not suitable for chips of different sizes. When replacing chips of different sizes, the placement frame of the corresponding size needs to be disassembled and reassembled, which is very inconvenient.

[0003] The publication (announcement) number is CN217719515U, which discloses a semiconductor discrete device bonding machine, including a bonding machine body, a processing table is installed on the upper surface of the bonding machine body, and a limiting structure is provided on the upper surface of the processing table. The limiting structure includes a support plate, the vertical cross-section of the support plate is "U"-shaped, and the two side arms of the support plate are fixedly connected to the processing table. The processing table is slidably connected with a slide plate relative to the support plate. The vertical cross-section of the slide plate is "L"-shaped, and the upper surface of the short arm of the slide plate is fixedly connected to the limiting plate. The processing table is fixedly connected with springs relative to the position of the two slides. The application sets a limiting structure to limit the position of chips of different sizes during the processing process, thereby saving the time spent by the staff to replace the placement frame, and thus facilitating the operation of the staff.

[0004] Although the above scheme can limit and locate the position of chips of different sizes, the equipment needs to cooperate with a large number of components such as springs, slides, limit plates, rollers, screws, nuts, etc. to limit the discrete device circuit chip, and the equipment needs to cooperate with a fixed plate, rectangular plate, positioning plate, nuts, auxiliary holes and levers to position the discrete device circuit chip. The equipment's limit structure and positioning structure for the discrete device circuit chip are relatively complex and troublesome to operate. For this reason, we propose a discrete device circuit processing and manufacturing device. Utility Model Content
