Description

Technical Field

[0001] This utility model specifically relates to an adjustable-depth adhesive plate, belonging to the field of semiconductor packaging technology. Background Technology

[0002] Currently, the process of applying flux to the chip for ball placement is as follows: Figure 1 As shown: The solder ball is placed face down, and the solder ball corresponds to the groove of the solder plate. The groove contains flux of the same depth as the solder ball, so as to ensure that a certain amount of flux is applied each time.

[0003] Figure 1 This is a cross-sectional view of the currently used adhesive plate. The bottom is fixed on the track. The ball-mounted chip 12 corresponds to the groove 11. When dipped in flux, the ball-mounted chip moves downward and moves upward after the action is completed, thus completing a single dip in flux.

[0004] Figure 2 This is a top view of the currently used adhesive sheet, which is a one-piece machined flat surface with a fixed-depth groove in the middle, which can be filled with flux.

[0005] This type of solder pad can meet the requirements of a specific product. However, when more or less flux is needed, the solder pad needs to be replaced, resulting in a waste of time and efficiency. Summary of the Invention

[0013] The second gear meshes with the first tooth and the third gear respectively.

[0014] On one side of the knob, the aforementioned rubber plate is provided with a pointer groove that passes through the plate wall, and the pointer that is fixed to the base plate passes through the pointer groove to the outside of the rubber plate;

[0015] The outer wall of the rubber plate is provided with a scale corresponding to the pointer, and the scale is used to indicate the groove depth.

[0017] The advantages of this utility model are:

[0018] This utility model discloses an adjustable-depth rubber sheet, which sets the bottom of the groove as a movable base plate and sets a height adjustment device at the bottom of the base plate. The height adjustment device is centered on a second rotating shaft, with a third gear linked by a knob as the power wheel on the outside and a first toothed part that links the lifting and lowering of the base plate as the driven part on the inside. The second gear and the fourth gear on the second rotating shaft are the transmission wheels.

[0019] This utility model discloses an adjustable-depth adhesive plate with a small groove depth adjustment range, which is micron-level.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Example

[0027] An adjustable-depth rubber sheet 1 is provided, the rubber sheet 1 having a slot 2 that extends through its top and bottom surfaces. A base plate 6, whose cross-section matches the slot 2, is horizontally placed inside the slot 2 to form a groove; the bottom of the base plate 6 is provided with a device for adjusting its raising and lowering along the slot 2.

[0028] The device consists of a first toothed section 7, a second rotating shaft 8, a second gear 9, a third rotating shaft 3, a third gear 5, and a knob 4.

[0029] A missing part is provided on either side of the bottom of the base plate 6.

[0030] The first tooth 7 is located on the side wall of the base plate 6 of the missing part and is arranged longitudinally.

[0031] The second gear 9 is coaxially fixed on the second rotating shaft 8, meaning that when the second rotating shaft 8 rotates, the second gear 9 is synchronously rotated. The second rotating shaft 8 is horizontally disposed in the slot 2, with both ends respectively axially connected to the hole wall of the slot 2, and the axial connection is located in the missing part.

[0032] The third rotating shaft 3 is permeable to the wall of the rubber plate 1; outside the rubber plate 1, a knob 4 is fixedly connected to one end of the third rotating shaft 3, and the other end of the third rotating shaft 3 is placed in the slot 2 and in the missing part, and the third gear 5 is fixedly connected to this end. That is, the knob 4 can be linked to the third gear 5 through the third rotating shaft 3.

[0033] The third rotating shaft 3 is parallel to the second rotating shaft 8.

[0034] When using,

[0035] Rotating the third gear 5 via the knob 4 causes the second gear 9, which is linked to the third gear 5, to rotate based on the second shaft 8. This causes the base plate 6 to rise and fall along the slot 2 via the linked first tooth 7, thereby adjusting the depth of the groove.

[0036] To facilitate observation and precise adjustment of the groove depth, a pointer 10 groove is provided on the side of the knob 4, which extends through the plate wall. The pointer 10, which is fixed to the base plate 6, extends through the pointer 10 groove to the outside of the plate 1 and points to the scale corresponding to the pointer 10 on the outer wall of the plate 1. This scale is used to indicate the groove depth. Example

[0037] Since the groove depth of the rubber plate 1 of this utility model needs to be adjusted to be on the micrometer level, based on the structure of embodiment 1, a coaxial fourth gear can be set on the second rotating shaft 8 for adjusting the gear ratio.

[0038] The fourth gear has a different diameter and a different gear ratio than the second gear 9; the fourth gear is used to mesh with the third gear 5.

[0039] That is, the third gear 5 is linked to the fourth gear, the fourth gear is linked to the second gear 9 through the second rotating shaft 8, and then the second gear 9 is linked to the first tooth part 7.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that the above embodiments do not limit this utility model in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of this utility model.
