First, recognize the thermal shock test chamber

1. What is the thermal shock test chamber?

Qin Zhuo A: The cold and hot impact box adopts the cold storage method, which is the static and cold alternating impact mode of the product to be tested, and the performance and parameters of the tested product after the temperature changes sharply.

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

Qin Zhuo A: The thermal shock test machine is used in electronic and electrical components, automation components, communication components, auto parts, metals, chemical materials, plastics and other industries, defense industry, aerospace, military industry, BGA, PCB base board, electronics The physical changes of chip IC, semiconductor ceramics and polymer materials, testing the material's repeated tensile force against high and low temperature and the chemical change or physical damage of the product in thermal expansion and contraction, can confirm the quality of the product, from the precision IC to heavy mechanical components, no need for its ideal test tool.

Second, how to choose a thermal shock test chamber?

1, impact temperature. The impact temperature is the maximum temperature range that the test zone can actually run. Note that it is not the extreme temperature of the preheating and pre-cooling chambers.
2, test load. This parameter directly affects how many test items can be placed. In general, the bigger the weight, the better.
3, return time. It refers to the time it takes for the test to all switch from one temperature point to another. Our common specification is â‰¤5min. The smaller the time, the better.
4, defrost time. The longer the defrost interval, the better. It is very desirable to have a manufacturer who can do 1000 cycles of defrosting once. The shorter the defrost interval, the worse the airtightness of the device!
5, sensor placement location. The specification requires that the sensor be placed inside the test area. Some manufacturers place the sensor inside the air duct. Although it is only 10cm away from the test area, this energy difference is quite large. It does not accurately reflect the temperature change on the surface of the test article.

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

1. The hot and cold impact test box produced and sold by Qinzhuo Ring Test Technology is delivered to the door in strict accordance with the order date, and dispatched technicians to come to the door for technical debugging.

2. The thermal shock test chamber produced and sold by our company will be guaranteed for two years and will be tracked and maintained regularly.

3. After the equipment warranty period, if there is a technical failure in the thermal shock test chamber, after the company is notified, the technician will come to the door and only charge the cost.

We have Organic Goji Berries planting bases 1000 HA, which certified by GMP, product facility has strickt control with HACCP and ISO. Organic goji berries are almost non-pesticide and non-pollution, so the quality is the highest in goji berries.

organic goji berries germination in Spring and flowering in April and September every year, picking in June to October. We use modern production equipment during drying, selecting and impurity removing, and according to the standardized production process combines enterprise quality inspection to ensure product quality.
