Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chip solderability test equipment, in particular to a chip solderability test clamping tool and welding test equipment. Background Art
[0002] During the assembly and welding process of electronic products, poor selection of circuit boards, component solderable ends, solder paste and flux quality will cause welding problems, which will directly affect the quality of the product. The main welding problems include poor wetting, bridging, cracks, etc., which will increase the workload of quality control and generate a large number of repairs, resulting in a waste of manpower and financial resources. For example, false welding, cold welding and poor welding strength will directly lead to reliability problems. Solderability testing tests the solderability of incoming materials, quantitatively evaluates the solderability of the tested samples, and directly provides guidance on whether the incoming materials can be put into production or can only be put into production after the process window is adjusted. For batches of incoming components, solderability testing is more meaningful for units with long storage time due to small production. Solderability evaluation can be performed on the components before they are used to determine whether the use of this batch of components will cause welding quality problems.
[0003] By implementing solderability testing, companies can determine the solderability of their products after production and assembly and the quality of their products.
[0004] However, in the current chip solderability test equipment, the fixture used to clamp the chip is relatively simple and can only be used for some smaller chips. Moreover, after long-term use, the fixture is easy to deform, which requires staff to frequently replace or maintain the fixture, resulting in low experimental efficiency. Utility Model Content

[0039] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0040] See also Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a chip solderability test clamping tool, including a connecting rod 100, a first clamp 200, a second clamp 300 and a clamping width adjustment member 400; both the first clamp 200 and the second clamp 300 are arranged at the bottom of the connecting rod 100, and the first clamp 200 and the second clamp 300 form a clamping tool; the clamping width adjustment member 400 is passed through the first clamp 200 and the second clamp 300 to adjust the clamping distance of the first clamp 200 and the second clamp 300 for clamping the chip 500 to be tested.
[0041] Specifically, when conducting experiments, the staff places the chip 500 to be tested between the first clamp 200 and the second clamp 300, and then the connecting rod 100 is moved to the inside of the equipment under the drive of the welding experimental equipment to conduct experiments. When it is necessary to clamp different chips 500 to be tested, the staff can adjust the clamping distance between the first clamp 200 and the second clamp 300 through the clamping width adjustment member 400 to meet the needs of different types of chips 500 to be tested; in addition, after clamping the same type of chip 500 to be tested for a long time, the staff can also adjust the clamping distance between the first clamp 200 and the second clamp 300 through the clamping width adjustment member 400, thereby eliminating the deformation error between the first clamp 200 and the second clamp 300, without replacing the clamp, thereby improving work efficiency.
[0042] Among them, both the first clamp 200 and the second clamp 300 include a top connecting plate 210, a side plate support plate 220 and a bottom clamping plate 230; the top connecting plate 210, the side plate support plate 220 and the bottom clamping plate 230 are connected in sequence, the top connecting plate 210 is connected to the connecting rod 100, and the clamping width adjustment member 400 is installed on the side plate support plate 220.
[0043] The top connecting plate 210 is provided with a connecting hole 211 for connecting with the connecting rod 100 .
[0044] The bottom outer wall of the connecting rod 100 is provided with an external thread, and the connecting rod 100 is connected to the connecting hole 211 through a nut 110 .
[0045] The connection hole 211 is a waist-shaped hole.
[0046] Among them, a mounting hole 221 for installing a clamping width adjustment member 400 is opened on the side panel support plate 220; the clamping width adjustment member 400 includes an adjusting bolt 410 and an adjusting nut 420; one end of the adjusting bolt 410 is passed through the two side panel support plates 220, and the adjusting nut 420 is connected to the adjusting bolt 410, so that the adjusting bolt 410 can limit the relative distance between the two side panel support plates 220.
[0047] Specifically, a waist-shaped hole is opened on the top connecting plate 210, and the connecting rod 100 is inserted into the waist-shaped hole. At least two nuts 110 are installed on the connecting rod 100, so that nuts 110 are arranged above and below the waist-shaped hole, thereby connecting the connecting rod 100 to the two top connecting plates 210.
[0048] In addition, when adjusting the clamping width adjustment member 400, the staff rotates the adjustment nut 420 on the adjustment bolt 410 to adjust the length of the adjustment bolt 410 between the two side plate support plates 220, that is, by pressing the two side plate support plates 220 closer to each other through the adjustment nut 420, or increasing the distance between the two side plate support plates 220, the clamping distance between the first clamp 200 and the second clamp 300 is adjusted to eliminate the deformation of the first clamp 200 and the second clamp 300 or adapt to different chips to be tested 500. In addition, during this adjustment process, the staff can loosen the nut 110 so that the connecting rod 100 can slide in the connecting hole 211.
[0049] A threaded spring may also be sleeved on the adjusting bolt 410. By setting the threaded spring, a certain pre-tightening force exists between the first clamp 200 and the second clamp 300, so that the staff can better clamp the chip 500 to be tested between the first clamp 200 and the second clamp 300, and the two ends of the threaded spring are respectively abutted against the two side support plates 220.
[0050] The top connecting plate 210 and the bottom clamping plate 230 are respectively disposed at two ends of the side plate supporting plate 220 , and the other ends of the top connecting plate 210 and the bottom clamping plate 230 are both facing the same side.
[0051] The width of the bottom clamping plate 230 gradually decreases from one end close to the side plate supporting plate 220 to the other end.
[0052] This embodiment provides a welding experiment device, including a chip weldability experiment clamping tool.
[0053] Specifically, the welding test equipment provided in this embodiment has the advantages of the above-mentioned chip weldability test clamping tooling compared with the prior art, which will not be described in detail here.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
