Abstract
Description
Technical Field
[0001] The utility model relates to the field of semiconductor reliability testing, in particular to a soldering flux collecting jig. Background Art
[0002] Before shipping, finished circuit board substrates must undergo thermal stress testing, and some substrates must also undergo solderability testing. During these tests, flux is evenly applied to the surface of the substrate under test. Existing techniques apply flux to both sides of the substrate and then place it vertically on a jig, allowing the flux to flow vertically. This process fails to effectively collect and utilize the flux that flows down the substrate surface during vertical placement, resulting in significant flux waste. Utility Model Content
[0003] In order to overcome the defects in the prior art, the embodiment of the present invention provides a flux collection fixture with a simple structure, which can automatically reflow and collect flux, reduce flux waste, and save costs.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] The utility model discloses a flux collecting jig, comprising:
[0006] A carrier, wherein a plurality of grooves are provided on the carrier, and mesh holes are provided at the bottom of the grooves to connect one side of the carrier with the other side;
[0007] The collecting device is arranged below the carrier, and the collecting device has an opening, the diameter of which is greater than or equal to the distance between the two grooves that are farthest apart.
[0008] The above technical solution opens a mesh hole on the carrier and connects the two sides of the carrier, so that when the flux drips onto the carrier, it can automatically flow along the mesh hole into the collecting device under the carrier, thereby realizing automatic reflow and collection of the flux. The above-mentioned flux collection fixture has a simple structure and is easy to operate. The recovered flux can be reused within its validity period, which can reduce flux waste and save costs.
[0009] Furthermore, the collecting device includes a reflux portion and a collecting portion, the reflux portion is arranged below the carrier and connected to the carrier, the opening is arranged at the top of the reflux portion, and the bottom of the reflux portion is provided with an outlet for the flux to flow out, and the collecting portion is arranged below the reflux portion and connected to the outlet of the reflux portion.
[0010] Furthermore, a cover is provided on the top of the collecting part, and an inlet for the flux to flow in is provided on the cover. The shape of the collecting part inlet is consistent with the shape of the reflux part outlet, and the size of the inlet on the collecting part cover is basically consistent with the size of the reflux part outlet.
[0011] The flux solution is an organic volatile substance. When collecting the flux, a cover needs to be set on the collecting device to reduce the volatilization of the flux. The collecting device is set as a reflux part for the flux to flow through and a collecting part for holding the flux. An opening is set in the reflux part, a cover is set on the collecting part, and a relatively small inlet is opened on the cover of the collecting part. The inlet is connected to the outlet to connect the reflux part and the collecting part. This can not only collect the flux, but also effectively reduce the volatilization of the flux. The size and shape of the outlet and the inlet are basically the same, so that the outlet of the reflux part can be inserted into the collecting part.
[0012] Furthermore, the reflux portion is funnel-shaped, and the diameter of the opening is larger than the diameter of the outlet. The larger opening of the reflux portion facilitates the recovery of all flux flowing down the grooves, while the smaller outlet reduces the contact between the flux and air, thereby reducing the volatilization of the flux.
[0013] Furthermore, the invention further comprises a hook provided on the lower side of the carrier, one end of the hook being connected to the carrier and the other end being connected to the collecting device. The provided hook can more easily connect the collecting device to the carrier, has a simple structure and is easy to operate.
[0014] Furthermore, the carrier is provided with a plurality of protrusions, and the plurality of protrusions are arranged at intervals along the length direction or the width direction of the carrier to form the groove.
[0015] Furthermore, the depth of the groove is configured such that a sample coated with solder flux placed in the groove is perpendicular or substantially perpendicular to the plane of the carrier. The groove is configured to secure the sample to the carrier, and the vertical placement of the sample allows the solder flux to flow evenly from top to bottom, allowing excess solder flux to flow back into the collection device.
[0016] Furthermore, a cabinet is provided below the carrier, and the collecting device is provided in the cabinet. The cabinet is used to support the carrier and store the collecting device for easy storage and arrangement.
[0017] Furthermore, the cabinet body is provided with at least one cabinet door, which can be opened and closed. The cabinet door is provided to facilitate the removal and cleaning of the collection device, making the process of recycling the soldering flux simpler.
[0018] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:
[0019] The present application opens a mesh hole on the carrier and connects both sides of the carrier, so that when the flux drips onto the carrier, it can automatically flow along the mesh hole into the collecting device below the carrier, thereby realizing automatic reflow and collection of the flux. The above-mentioned flux collection fixture has a simple structure and is easy to operate. The recovered flux can be reused within its validity period, which can reduce flux waste and save costs.

[0028] Reference Figure 1 and Figure 2 The present invention provides a flux collection fixture for automatically reflowing and collecting flux solution when a sample 8 coated with flux is at rest. The flux collection fixture includes a carrier 1 and a collection device. The carrier 1 is provided with a plurality of grooves 4. The bottom of the grooves 4 is provided with mesh holes connecting one side of the carrier 1 with the other side. The collection device is provided below the carrier 1 and has an opening. The diameter of the opening is greater than or equal to the distance between the two grooves 4 that are the farthest apart. The flux flowing down from the plurality of flux-coated samples 8 can be completely collected.
[0029] With the help of the above structure, the jig in the embodiment of the present application can enable the flux to automatically flow along the mesh into the collection device under the carrier when it drips onto the carrier, thereby realizing automatic reflow and collection of the flux. Moreover, the flux collection jig has a simple structure and is easy to operate. The recovered flux can be reused within its validity period, which can reduce flux waste and save costs.
[0030] Reference Figure 1 and Figure 2As shown, in the embodiment of the present application, the carrier 1 is provided with a plurality of bumps 6, which are arranged at intervals along the length or width of the carrier 1 to form the groove 4. The bottom of the groove 4, i.e., the side where the carrier 1 connects to the bumps 6, is provided with a mesh. The mesh extends from the side where the carrier 1 connects to the bumps 6 to the other side of the carrier 1 away from the bumps 6, and connects the two sides of the carrier 1, thereby allowing the flux to flow from the mesh into the collection device 2.
[0031] The depth of the groove 4 is set so that the flux-coated sample 8 can be fixed on the carrier 1. The flux-coated sample 8 can be placed at an angle or vertically as long as it remains stable. Preferably, the depth of the groove 4 is set so that the flux-coated sample 8 placed in the groove 4 is perpendicular or approximately perpendicular to the plane of the carrier 1. This ensures that the flux solution flows evenly from top to bottom on the sample surface.
[0032] In other embodiments, the groove 4 can be directly formed on the carrier 1 , and mesh holes can be formed from the bottom of the groove 4 , and the mesh holes can extend to a side of the carrier 1 facing away from the groove 4 .
[0033] like Figure 1 As shown, the flux collecting fixture also includes a reflow device 3, which is arranged below the carrier 1 and connected to the carrier 1. When collecting the flux, the reflow device is connected to the collecting device through the reflow device, so that the collecting device is provided with a smaller opening to avoid large-area contact of the flux with the air and volatilization.
[0034] The collection device includes a reflux portion 2 and a collection portion 3. The reflux portion 2 is located below the carrier 1 and connected to the carrier 1. The opening is located at the top of the reflux portion 2. The bottom of the reflux portion 2 is provided with an outlet for the flux to flow out. The collection portion 3 is located below the reflux portion 2 and is connected to the outlet of the reflux portion 2. The opening is used to receive the flux flowing down from the mesh, and the outlet is used to flow the flux into the collection portion 3.
[0035] In order to further reduce the volatilization of the soldering flux, the reflux portion 2 is configured to be funnel-shaped, and the diameter of the opening of the reflux portion 2 is larger than the diameter of the outlet of the reflux portion 2 .
[0036] Among them, a cover is provided on the top of the collecting part 3, and an inlet for the flux to flow in is provided on the cover. The inlet of the collecting part 3 is connected to the outlet of the reflux part 2. The shape of the inlet of the collecting part 3 is consistent with the shape of the outlet of the reflux part 2, and the size of the inlet of the collecting part 3 is basically consistent with the size of the outlet of the reflux part 2.
[0037] It should be noted that the reflux portion 2 and the collecting portion 3 in the above embodiment are communicated, and the reflux portion 2 and the collecting portion 3 may be fixedly connected via the outlet and the inlet, or may be detachably connected.
[0038] In order to connect the reflux unit 2 to the carrier 1, in the embodiment of the present application, a hook 5 is provided on the lower side of the carrier 1, one end of the hook 5 is connected to the carrier 1, and the other end is connected to the reflux unit 2. The connection between the hook 5 and the reflux unit 2 makes the installation and removal of the reflux unit 2 more convenient.
[0039] In a possible embodiment, in order to facilitate storage and organization, a cabinet 7 is provided below the carrier 1 , and the collecting device is disposed in the cabinet 7 .
[0040] In order to facilitate the taking and placing of the soldering flux, the cabinet body 7 is provided with at least one cabinet door, and the cabinet door can be opened and closed.
[0041] Reference Figure 2 As shown, when the flux collection fixture in the present application is used, first apply flux on both sides of the sample that needs to be coated with flux, then place the sample 8 coated with flux vertically in the groove 4 of the carrier 1, and let it stand for 1 to 2 minutes. The excess flux on the surface of the sample 8 coated with flux will automatically flow downward along the mesh holes set on the carrier 1 and the reflow part 2 under the carrier 1, and finally flow into the collection part 3 under the reflow part 2.
[0042] The present invention uses specific embodiments to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation methods and application scope.
