Buy the top-secret five-piece of the hot and cold shock chamber

I. Understanding cold and hot shock chamber

1. What is a hot and cold shock test box?

Qin Zhuo A: The cold and hot shock box adopts a cold storage method, which allows the product to be tested to stand by cold and hot alternate impacts. The performance and parameters of the tested product after a rapid temperature change are tested.

2. What are the uses of the thermal shock chamber?

Qin Zhuo A: Hot and cold impact testing machine is used in electronic and electrical components, automation components, communication components, automotive parts, metals, chemical materials, plastics and other industries, defense industry, aerospace, military industry, BGA, PCB base pull, electronic The physical changes of chip ICs, semi-conductor ceramics and macromolecules are used to test the repeated resistance of high- and low-temperature materials, and the chemical changes or physical damages caused by thermal expansion and contraction of the products. The quality of the products can be confirmed. From IC to heavy mechanical components, none need its ideal test tool.

Second, how to choose the hot and cold impact test box?

1, the impact temperature. The impact temperature is the maximum temperature range that the test zone can actually reach. Note that it is not the preheating and precooling chamber limit temperatures.
2, test load. This parameter directly affects how many test articles can be placed. In general, the bigger the weight, the better.
3, return time. It refers to the time taken for a test article to switch from one temperature point to another. Our common specification is ≤ 5min. The smaller this time, the better.
4, defrost time. The longer the defrosting interval, the better. Now there are writers who can do 1000cycles to defrost once, which is ideal. The shorter the defrost interval, the worse the airtightness of the device!
5, sensor placement. The specification requires that the sensor must be placed inside the test area. Some manufacturers place the sensor inside the air duct. Although there is only a 10cm distance from the test area, this energy difference is quite large. And can not truly reflect the surface of the test product temperature changes.

Third, the purchase of thermal shock test box, after-sales service how?

1. Qinzhuo Ring Measurement Technology Co., Ltd. manufactures and sells hot and cold impact test boxes, delivers them on the order date strictly, and dispatches technical personnel to come to the door to perform technical debugging of the equipment.

2. The hot and cold impact test box produced and sold by our company will be guaranteed for two years and will be tracked and maintained regularly.

3. After the warranty period of the equipment, such as the technical failure of the thermal shock test box, after the announcement of our company, the technical personnel will come to the door and only charge the cost of the work.
