Description

Technical Field

[0001] This utility model relates to the field of circuit testing technology, and in particular to an integrated circuit test carrier board. Background Technology

[0002] Integrated circuit boards are made by integrating electronic components such as processors, resistors, capacitors, and wiring onto a carrier according to specific processes to form a complete circuit before packaging. During the production process, integrated circuit boards should also be tested to ensure their safe operation.

[0003] When inspecting integrated circuit boards for cold solder joints and missing solder joints, it is usually necessary to flip the board over and inspect each solder joint on the back. However, if the integrated circuit board is laid flat on a table for inspection, the connection points of the components on the front of the board may be compressed, affecting the stability and quality of the solder joints, causing damage to the components, and consequently affecting the overall function and lifespan of the board. Utility Model Content

[0004] The technical problem this invention aims to solve is that when flipping a circuit board to detect poor soldering and missing solder joints, the connection points of components on the front side are easily subjected to pressure.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an integrated circuit test carrier board, including a test carrier board, with rotating seats fixedly connected to both sides of the top of the test carrier board, rotating support arms rotatably provided on the rotating seats, and a limiting frame fixedly provided between the two rotating support arms, and the limiting frame is a semi-enclosed rectangular frame, with two clamping components slidably connected to one side of the limiting frame, and a border seal being snapped onto the side of the limiting frame away from the clamping components.

[0006] As a further improvement of this utility model, the clamping assembly includes a main body compartment that is slidably disposed on the limiting frame. A telescopic rod is fixedly disposed inside the main body compartment, and a spring is sleeved on the telescopic rod. A clamping plate is fixedly connected to the bottom end of the telescopic rod and one side of the main body compartment.

[0007] As a further improvement of this utility model, a sliding plate is fixedly connected to the side of the main compartment away from the clamping plate, and the limiting frame is provided with a sliding groove for sliding connection between the sliding plate and the clamping plate.

[0008] As a further improvement of this utility model, a groove is provided on one side of the frame seal for the circuit board to be embedded and snapped in.

[0009] As a further improvement of this utility model, the two ends of the frame seal are fixedly connected with snap-fit ​​protrusions, and the inner walls on both sides of the limiting frame are provided with through grooves that match the snap-fit ​​protrusions.

[0010] As a further improvement of this utility model, support columns are fixedly connected to the four corners of the bottom end of the test plate, and the support columns are provided with multiple through holes. The support columns are slidably fitted with heightening sleeves, and the heightening sleeves are inserted with limit bolts that pass through the through holes.

[0011] The beneficial effects of this invention are as follows: Rotary seats are fixed on both sides of the top of the test carrier. The rotating seats are connected to the limiting frame via rotating arms. Because the limiting frame is rotatably connected to the rotating seats, the test angle can be flexibly adjusted, while avoiding the risk of damage to some circuit components due to the circuit board flipping and pressing. Through the clamping components and the frame seal, a reliable connection effect can be provided for the circuit board to be tested, ensuring connection stability during multi-angle adjustment.

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] This utility model provides the following: Figure 1-4 As shown, an integrated circuit test substrate includes a test substrate 1. Rotary seats 2 are fixedly connected to both sides of the top of the test substrate 1. Rotary support arms 3 are rotatably mounted on the rotating seats 2. A rotating handle is fixedly mounted at one end of each rotating support arm 3. A limiting frame 4 is fixedly mounted between the two rotating support arms 3. The limiting frame 4 is a semi-enclosed rectangular frame. Two clamping components 5 are slidably connected to one side of the limiting frame 4. A border seal 6 is snapped onto the side of the limiting frame 4 away from the clamping components. Support columns 10 are fixedly connected to the four corners of the bottom of the test substrate 1. Multiple through holes are formed in each support column 10. An increasing sleeve 11 is slidably fitted onto each support column 10. Limiting bolts through the through holes are inserted into the increasing sleeve 11. The support columns 10, increasing sleeves 11, and limiting bolts provide an extended height for the test substrate 1, which can be adjusted according to the operator's operating height.

[0021] like Figure 4 As shown, the clamping assembly 5 includes a main body compartment 501 slidably disposed on the limiting frame. A telescopic rod 502 is fixedly disposed inside the main body compartment 501, and a spring is sleeved on the telescopic rod 502. One end of the spring is fixedly connected to the main body compartment 501, and the other end is fixedly connected to the bottom of the telescopic rod 502. Clamping plates 503 are fixedly connected to the bottom end of the telescopic rod 502 and one side of the main body compartment 501. The two clamping assemblies 5 are used to provide limiting clamping for the circuit board. A sliding plate 7 is fixedly connected to the side of the main body compartment 501 away from the clamping plate 503. The limiting frame 4 has a sliding groove for sliding connection of the sliding plate 7 and the clamping plate 503. The sliding plate 7 and the sliding groove provide good guidance for the movement of the clamping assembly 5.

[0022] like Figure 2 As shown, a groove 8 is provided on one side of the frame seal 6 for the circuit board to be embedded and snapped in; this provides a fitting and fixing effect for the circuit board and ensures the reliability of the connection. Snap-in protrusions are fixedly connected to both ends of the frame seal 6, and through grooves 9 matching the snap-in protrusions are provided on the inner walls of both sides of the limiting frame 4; the frame seal 6 is slid inwards through the snap-in protrusions into the through grooves 9, so that the other side of the circuit board held by the clamping component 5 is snapped in by the frame seal 6.

[0023] Working Principle: In practical implementation, according to the length of the circuit board, the two clamping components 5 on the limiting frame 4 are slid to the corresponding sides of the circuit board to ensure stable clamping. The clamping plates 503 located at the bottom of the telescopic rod 502 are pulled downwards, causing the telescopic rod 502 to move downwards. The spring deforms accordingly, placing the circuit board between the two clamping plates 503. Then, the clamping plates 503 are released, allowing the spring to return to its original state, and the telescopic rod 502 springs back and retracts. Based on the above principle, the two sets of clamping plates 503 clamp and limit the circuit board. Next, the frame seal 6 is slid into the through grooves 9 on the inner walls of both sides of the limiting frame 4 according to the snap-fit ​​protrusions on both sides, until the groove 8 on the inner side of the frame seal 6 snaps into the edge of the circuit board, finally making the circuit board tightly connected to the limiting frame 4. Then, by rotating the handle at one end of the rotating support arm 3, the test angle of the circuit board can be changed, facilitating testing operations.
