Description

Technical Field

[0001] This utility model relates to the field of SMT surface mount technology, and in particular to a snap-fit ​​countersunk plate type repair fixture. Background Technology

[0002] In the SMT process of electronic manufacturing, circuit boards need to be soldered using a solder bath.

[0003] Most existing repair fixtures suffer from inconvenient operation and unstable fixation when passing through the solder pot. For example, some fixtures use screws for fastening, which is not only cumbersome to operate but also easily scratches the circuit board. Other temporary fixation fixtures may loosen under high temperature conditions, leading to a decrease in soldering quality. Therefore, it is necessary to design a more convenient, stable repair fixture that will not damage the circuit board. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to solve the problems raised in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a snap-fit ​​countersunk plate type repair fixture, comprising a repair fixture body, characterized in that: according to the size and shape of the component to be repaired or processed, a suitable repair fixture body is selected, the component is placed in the corresponding position on the repair fixture body, and then the snap-fit ​​is operated manually or mechanically to sink the snap-fit ​​and press the component to achieve fixation. After the repair or processing is completed, the snap-fit ​​is released and the component on the repair fixture body can be removed.

[0006] Preferably, the maintenance fixture body is a combination of two sets of BOT surfaces and TOP surfaces, and the two sets of BOT surfaces and TOP surfaces are arranged in a large and a small configuration.

[0007] Preferably, the body of the repair fixture is made of 6mm thick synthetic stone.

[0008] Preferably, the recessed area of ​​the maintenance fixture body is 0.5 mm deep.

[0009] Preferably, the green area of ​​the maintenance fixture body is excavated.

[0010] Preferably, the yellow area of ​​the maintenance fixture body is 3.0 mm deep.

[0011] Preferably, the lettering on the front of the maintenance fixture body is beveled at the acute angle.

[0012] Preferably, the magenta part of the body of the repair fixture is cut through.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In the SMT process of electronic manufacturing, such as during repair, components such as circuit boards are prone to displacement due to factors such as hot air and their own weight, resulting in poor soldering and other quality problems. This fixture can provide stable pressure and fixation through the structure of the snap-on plate, ensuring that the circuit board or other components maintain accurate position during repair or processing, avoiding positional deviation. It is simple and convenient to operate and improves work efficiency.

[0015] (2) The snap-on countersunk plate maintenance fixture improves the production cycle. Because the snap-on countersunk plate maintenance fixture is simple to operate and reliable to fix, it can reduce the waiting time and adjustment time in the maintenance process, making the production process smoother, thereby improving the production cycle of the entire production line and increasing the output of products.

[0016] (3) The press-fit countersunk plate maintenance fixture reduces the scrap rate. Stable fixing and accurate positioning help improve welding quality and the success rate of other maintenance operations. It reduces the generation of scrap due to position deviation, poor welding and other reasons, reduces production costs and improves the economic benefits of enterprises.

[0017] (4) The snap-fit ​​countersunk plate maintenance fixture reduces labor costs and its ease of operation allows staff to complete maintenance tasks more quickly, reducing the time and workload of manual operation and thus reducing labor costs. In addition, the simple structure also facilitates the training and operation of new employees, reducing the costs incurred due to personnel training. Attached Figure Description
