Description

Technical Field

[0001] The utility model belongs to the technical field of memory bar testing, in particular to an automatic and precise temperature control system for memory bar testing. Background Art

[0002] After the memory sticks are mounted and divided into boards, they must be functionally tested in a constant temperature environment. After the test is completed, the memory sticks will be sorted into multiple grades based on the test results.

[0003] During the test, the difference in surface temperature of the memory stick has a great influence on the test result. The greater the temperature difference on the surface of the memory stick, the more low-grade memory sticks will be sorted out. Therefore, the test process requires precise constant temperature. The existing method of heating the memory stick is usually to blow hot air on the surface of the memory stick to raise the temperature to a certain temperature and maintain this temperature. The hot air circulation method is to blow from one end of the memory stick to the other end, and then the wind is recovered and heated by the heater before blowing out again. Because the wind always blows from one end to the other, and the air duct is long, the temperature difference between the two ends of a memory stick is large, and ultimately there are more low-grade memory sticks and fewer high-grade memory sticks, resulting in inaccurate test results. Utility Model Content

[0004] In view of this, the purpose of the utility model is to overcome the deficiencies in the prior art and provide an automatic and precise temperature control system for memory stick testing. The present application provides the following technical solutions:

[0005] An automatic and precise temperature control system for memory bar testing, comprising a temperature box, a memory bar and a hot air component;

[0006] The memory bar and the hot air component are arranged in the temperature box, the hot air component is installed above the memory bar, there are two groups of hot air components, and the two groups of hot air components are symmetrically arranged above the memory bar so as to blow hot air to both ends of the memory bar respectively through the two groups of hot air components.

[0007] In a possible embodiment, each group of the hot air components includes an air outlet channel, a return air duct, a return air fan and a heater. The air outlet channel is arranged above the memory bar, one end of the air outlet channel is connected to one end of the return air duct, and the other end of the air outlet channel is located at an end of the corresponding memory bar. The return air fan and the heater are arranged in the return air duct, and the heater is arranged close to the air outlet channel.

[0008] In a possible embodiment, an air outlet is provided at the bottom of the air outlet channel.

[0009] In a possible embodiment, the return air duct is a U-shaped channel.

[0010] In a possible embodiment, a return port is provided at one end of the return air duct away from the air outlet channel.

[0011] In a possible embodiment, a control system is further included, and the control system is connected to the hot air component to control the operation of the hot air component.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] The utility model improves the existing memory stick temperature control system, and changes the existing one-way hot air blowing from one end of the memory stick to two independent hot air components set in the middle position above the memory stick, which blow hot air to both ends of the memory stick respectively, shortening the length of the air duct, thereby reducing the temperature difference at both ends of the memory stick. At the same time, the two hot air components have their own independent fans and heaters. Therefore, the utility model can independently adjust the internal temperature of each return air duct according to the temperature difference at both ends of the memory stick. In this way, the temperature difference on the surface of the memory stick can be controlled within a smaller range, stabilizing the temperature. The memory stick is more stable and accurate during testing, thereby sorting out a larger number of high-grade memory sticks.
