Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the present invention includes a frame body 1 and two handles 5 affixed to one side of the frame body 1, and the frame body 1 is provided with several support frames for supporting lead frames with staggered pins 6. A support bar is fixedly connected to the horizontal frame line of the support frame 6, and the shape of the support bar is consistent with the shape of the gap between the staggered pins of the lead frame.

[0016] The support frame 6 can be one, two, four, preferably four, evenly distributed in the frame body 1, so that the amount of material loaded at one time is more, and more than eight ultra-wide and ultra-dense staggered arrays can be loaded at a time Lead frames, of course, can also be divided into smaller grids, which can accommodate more lead frames at a time.

[0017] Since the products on the lead frame are cl...

Abstract

The invention discloses a loading frame for a lead frame with staggered pins. The loading frame comprises a frame body (1) and two handles (5), wherein the two handles (5) are fixedly connected to one side of the frame body (1); a plurality of support frames (6) which are used for supporting the lead frame with the staggered pins are arranged in the frame body (1); support strips are fixedly connected to horizontal frame lines of the support frames (6); and the shape of each support strip is consistent with that of a gap between every two staggered pins of the lead frame. The support strips, each of which the shape is consistent with that of the gap between every two staggered pins of the lead frame, extend to the staggered pins of the lead frame to support the lead frame, so that the modular surface utilization rate is increased; the lead frame can be placed more stably by a support plate; and due to adoption of four lead frames, the loading amount is larger, and 8 lead frames can be loaded once.

Description

technical field [0001] The invention relates to a loading frame, in particular to a loading frame for a lead frame with staggered pins. Background technique [0002] At present, in the subsequent packaging process of integrated circuit semiconductors, due to the development of the structural design of the lead frame to multiple rows and columns, and the width of the lead frame is also limited, it is required to enable packaging on the original width of the strip. Most of them are products, and the individual spacing of products is smaller and denser. In this way, the design of the lead frame feeding device has gradually become a bottleneck, and higher requirements are put forward for the design, processing and quality of the lead frame. The existing lead frame feeding rack is increasingly unsuitable for the design of integrated circuit semiconductor chips, The rapid development of industries such as semiconductor back-end packaging. The existing lead frame loading frame ha...
