1、 What are the uses of cold and hot shock test chamber?
The cold and hot shock test chamber is applicable to the safety performance test of electronic components, providing reliability test, product screening test, etc. at the same time, through this equipment test, the reliability of products can be improved and the quality control of products can be carried out.
2、 How to buy cold and hot shock test chamber?
1. The temperature of the impact zone can be reduced to the maximum. Note that it is not the limit temperature of preheating and precooling chamber.
2. Test load: this parameter directly affects how many test objects can be placed.
3. Recovery time: refers to the time taken for the test workpiece to switch from one temperature point to another. Common standards stipulate ≤ 5min.
4. Defrosting time: the longer the defrosting interval, the better. Now some manufacturers can defrost once every 1000 cycles, which is very ideal. The shorter the defrosting interval, the worse the air tightness of the equipment!
5. Sensor placement: according to the specification, the sensor must 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, the energy difference is quite large. And it can not truly reflect the temperature change of the surface of the tested workpiece.
3、 How about after-sales service when purchasing cold and hot shock test chamber?
1. The cold and hot shock test boxes produced and sold by Zhongtian instrument are delivered to the door in strict accordance with the order date, and technicians are sent to install and debug free of charge on site, and the operators are trained free of charge until the operators can operate independently.
2. For the cold and hot shock test box produced and sold by our company, Zhongtian instrument shall be guaranteed free of charge for one year (from the date of installation and acceptance), and spare parts and after-sales service shall be provided for life for 48 hours.
3. After the warranty period of the equipment, if there is any fault in the cold and hot shock test chamber, after notifying our company, the technicians will provide door-to-door service and charge only the production cost.
