Abstract
Description
Technical field:
[0002] The invention relates to the field of integrated circuit salt spray test equipment, in particular to an integrated circuit salt spray test sample fixing device. Background technology:
[0004] The salt spray test requires that the test sample be fixed at a certain angle in the salt spray test chamber so that each point on the outer surface of the sample is evenly placed in the salt spray test chamber. At present, the fixation of domestic test samples is to use cotton ropes to tie them up, and then hang them in the salt spray test chamber for testing. The cotton ropes not only cause part of the test sample area to not be exposed to the salt spray environment, but also make it impossible to control the tilt angle of the test sample according to the test requirements. Summary of the invention:
[0006] The present invention aims to overcome the deficiencies in the prior art and provides a device for fixing integrated circuit salt spray test samples.
[0007] This application provides the following technical solutions:
[0008] A salt spray test sample fixing device for integrated circuits includes a base, and is characterized in that: a group of slots are provided on the base, a movable rotating plate is provided in the slots, a slot is provided on the rotating plate, a slot that can be connected to the slot is provided on the base, a test sample plug-in board is plugged between the slots, a locking pin corresponding to one of the rotating plates is provided on the base, a rocker arm connected to the rotating plate is provided on the base, and a plurality of groups of jacks are provided on the test sample plug-in board.
[0009] On the basis of the above technical solutions, there are also the following further technical solutions:
[0010] An arc-shaped notch is provided on one of the rotating plates, and one end of the locking pin is inserted into the notch to form a corresponding fit therewith.
[0011] A limiting block corresponding to the groove body is connected to one end of the locking pin.
[0012] A plurality of through slots are arranged on the plug board, and each group of jacks is distributed in one through slot.
[0013] The jack is a tapered hole.
[0014] Advantages of the invention:
[0015] The invention has a simple structure and is easy to use. It can quickly realize the installation and fixation of the test sample and the adjustment of the angle of the test sample in the test box, so that the surface of the sample can be fully exposed to the salt spray test, which can not only improve the work efficiency and simplify the work process, but also improve the accuracy of the test. Description of the drawings:
[0017] Figure 1 It is a schematic diagram of the overall structure of the present invention;
[0018] Figure 2 It is a partial structural diagram of the test sample plug-in board;
[0019] Figure 3 It is a schematic diagram of the structure of the cooperation between a rotating plate and a base of the present invention. Specific implementation method:
[0021] like Figure 1-3 As shown, a salt spray test sample fixing device for integrated circuits includes a base 1, wherein the base 1 includes a bottom plate 1a, and a vertically distributed upright plate 1b is respectively provided at both ends of the upper surface of the bottom plate 1a. A circular groove body 2 is respectively provided on the inner side walls of the two upright plates 1b, and the two groove bodies 2 are coaxially distributed.
[0022] A rotatable circular rotating plate 3 is installed on each trough body 2. A slot 4 is provided on each rotating plate 3, and a trough body 5 that can be connected to the slot 4 is also provided on each vertical plate 1b, and the trough body 5 is horizontally distributed. An arc scale (not shown in the figure) corresponding to the slot 4 is also provided on the vertical plate 1b outside one of the trough bodies 2. The slot 4 and the trough body 5 have the same width.
[0023] A rocker arm 8 is installed on one of the vertical plates 1b, one end of which is inserted into the slot body 2 of the vertical plate 1b and connected to the rotating plate 3 therein, and the rotating plate 3 can be driven to rotate in the slot body 2 through the rocker arm 8. An arc-shaped notch 3a is provided on the outer edge surface of the rotating plate 3 in the slot body 2, and a locking pin 7 is penetrated at the top of the vertical plate 1b, and the lower end of the locking pin 7 extends into the notch 3a and forms a locking fit with the bottom surface of the notch 3a. The locking pin 7 is a bolt structure, and a limit block 7a corresponding to the slot body 2 is connected to the lower end of the locking pin 7. The limit block 7a prevents the locking pin 7 from falling off the vertical plate 1b due to the rotation transition of the staff.
[0024] A test sample plug-in board 6 is inserted between the slots 4. The test sample plug-in board 6 is provided with a plurality of through slots 6b distributed along the length direction of the test sample plug-in board 6. A group of jacks 6a distributed along the axial direction of the through slot 6b are distributed at the bottom of each through slot 6b. The jacks 6a are tapered hole structures with a larger upper portion and a smaller lower portion.
[0025] The spacing between adjacent through slots 6b is 5mm, the spacing between adjacent insertion holes 6a in the same group is 3mm, and the width of the through slots 6b is the same as the diameter of the upper end of the insertion hole 6a, both of which are 2mm.
[0026] Usage process:
[0027] First, insert the pins of the sample (integrated circuit) that needs to undergo salt spray test into the socket. In actual operation, since the pins are not very regular, only a part of the pins can be smoothly inserted into the socket, and the other irregular pins will be bent and distributed in the through groove. As long as the pins inserted into the socket can support the shell of the integrated circuit suspended on the test sample plug-in board, it will be fine.
[0028] Then, the test sample plug-in board is inserted into the slot 4 through the slot body 5, and then the swing arm 8 is shaken to rotate the rotating plate 3 to drive the test sample plug-in board to tilt to a suitable position, and then the rotating plate 3 is locked by the locking pin 7, that is, the base 1 is placed in the salt spray test box for salt spray test. Generally, the tilt angle of the test sample plug-in board of this device is within 0-20 degrees.
[0029] Since the inventor first set the jack on the test sample plug board when making the present invention, and then found that the irregular pins could not be inserted into the jack during use, he set a through slot on the test sample plug board, so Figure 2 The jack shown in the figure will be partially located in the bottom area of the slot and partially located above the wall area of the slot.
