Description

Technical Field

[0001] This utility model relates to integrated circuit packaging technology, specifically to a lead frame cassette. Background Technology

[0002] In the past, lead frame boxes contained lead frames that were supported with the middle part suspended in the air. For some thinner lead frames, the middle part would sag, causing deformation. Utility Model Content

[0003] In view of the above problems, this utility model proposes a lead frame material box.

[0004] The technical solution of this utility model: A lead frame material box, wherein the material box has end cover plates at the front and back, and toothed grooves are symmetrically arranged on the left and right sides inside the material box; a plurality of lead frames are placed inside the material box, and the two ends of each lead frame are resting on the teeth of the toothed grooves; a plurality of support plates are provided inside the material box, and the support plates support the lead frames.

[0005] The aforementioned tray design increases the difficulty of cleaning the inside of the material box and easily leaves blind spots. To further refine the above technical solution, the tray is mounted on the teeth of the toothed groove, and the tray is embedded within the teeth of the groove with a clearance fit. Thus, the tray can be removed during cleaning; additionally, if the lead frame has sufficient strength, the tray can be removed entirely.

[0006] To further refine the above technical solution, the pallet has protrusions on both its front and rear sides to restrict its forward and backward movement.

[0007] To further refine the above technical solution, the tray is provided with a number of circular holes.

[0008] To further refine the above technical solution, end caps are installed at the front and rear of the material box, and the end caps seal the front and rear openings of the material box.

[0009] The advantages of this utility model are that it has a reasonable design and simple structure. The design includes a support plate to support the lead frame, which provides support for the middle part of the lead frame and prevents the middle part of the lead frame from sagging and deforming.

[0013] The diagram shows a material box 1, a toothed groove 1-1, a support plate 1-2, a protrusion 1-2-1, a round hole 1-2-2, and an end cover plate 1-3. Detailed Implementation

[0014] like Figure 1-3 As shown: A lead frame material box 1 has openings at the front and back, and symmetrical toothed grooves 1-1 are arranged on the left and right sides inside the material box 1; several support plates 1-2 are arranged inside the material box 1, the support plates 1-2 are mounted on the teeth of the toothed grooves 1-1, and the support plates 1-2 are embedded in the teeth of the toothed grooves 1-1 with clearance fit; the support plates 1-2 have protrusions 1-2-1 on the front and back sides; several round holes 1-2-2 are distributed on the support plates 1-2; end caps 1-3 are installed at the front and back of the material box 1, and the end caps 1-3 block the front and back openings of the material box 1.

[0015] In use: Several lead frames are placed in the material box 1, and the two ends of the lead frames are placed on the teeth of the toothed groove 1-1 and supported on the tray.

[0016] The above embodiments are only for illustrating the technical concept and features of the utility model, and are intended to enable those skilled in the art to understand the content of the utility model and implement it accordingly. They should not be construed as limiting the scope of protection of the utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the utility model should be covered within the scope of protection of the utility model.
