Technical Means of Precise Temperature Control in High and Low Temperature Test Chamber

The high and low temperature test chamber is used to test the adaptability of materials or products in high and low temperature environments, and its accurate temperature control is achieved in the following ways:

1, Temperature control system

High and low temperature test chamber usually adopts temperature control system to achieve accurate temperature control. The system consists of temperature sensors, controllers and heaters. The temperature sensor is placed inside the test chamber to monitor the temperature change in real time, and the controller automatically controls the output power of the heater according to the signal of the sensor to achieve the purpose of accurate temperature control.

2, Temperature fluctuation control

Temperature fluctuation is an important index of accurate temperature control in high and low temperature test chamber. In order to ensure the stability of the temperature inside the test chamber, the controller will reduce the temperature fluctuation by adjusting the output power of the heater. Under normal circumstances, the accuracy of temperature fluctuations is required to be within 0.2°C.

3, Sealing control

The tightness of the high and low temperature test chamber is one of the important factors to ensure accurate temperature control. The tightness of the test chamber needs to be ensured by strict airtight testing to ensure that the heat inside the test chamber does not leak to the outside, or the heat from the outside does not enter the inside.

4, Time control

The time control of high and low temperature test chamber is also an important means to ensure accurate temperature control. The controller can set the test time according to the test needs, and automatically stop the test after the test time arrives to ensure the safety of the test sample.

In summary, the accurate temperature control of the high and low temperature test chamber is achieved through the joint action of many factors such as temperature control system, temperature fluctuation control, sealing control and time control.

Use Principle of High and Low Temperature Test Chamber Low Temperature and Constant Temperature Tank 

Because of its own circulation system, the uniformity of temperature field is very high, and more and more experiments are applied to the low temperature constant temperature tank. Mainly used in petroleum, chemical, electronic instrumentation, physics, chemistry, biological engineering, medicine and health, life science, light industrial food, physical property testing and chemical analysis and other research departments, colleges and universities, enterprise quality inspection and production departments, to provide users with a hot and cold controlled, uniform and constant temperature field source for test samples or products to perform constant temperature test or test. It can also be used as a heat source or cold source for direct heating or cooling and auxiliary heating or cooling.

What are the precautions for using a low temperature or constant temperature tank?

1, Before the use of low temperature constant temperature tank, the tank should be added to the liquid medium (pure water, alcohol, methyl silicone oil), the medium liquid level should be less than 20mm workbench, otherwise the power will damage the heater.

2, The selection of liquid medium in the low temperature constant temperature tank should comply with the following principles:

When the operating temperature is below 5 ° C, the liquid medium is generally alcohol;

When the operating temperature is 5 ~ 85℃, the liquid medium is generally water;

When the working temperature is 85 ~ 95℃, the liquid medium can choose 15% glycerol aqueous solution, which can reduce the evaporation of water;

When the operating temperature is higher than 95 ° C, oil is generally selected as the liquid medium, and the open cup flash point value of the selected oil should be higher than the operating temperature of 50 ° C or more; Generally, methyl silicone oil with low viscosity is used.

3, Power supply: 220V50Hz, the power supply should be greater than the total power of the instrument, the power supply must have a good "grounding" device.

4, The instrument should be placed in a dry and ventilated place, and there are no obstacles within 300mm around the instrument.

5, When the thermostat working temperature is high, should be careful not to open the cover, hands do not enter the groove, to prevent hot injury.

6, After using, all switches are placed in the off state, cut off the power.

7, Avoid acid and alkali substances into the tank corrosion coil and inner liner.

8, The instrument should do a good job of regular cleaning work, long-term use, empty the media in the tank, and wipe clean, keep the workbench and the operating panel clean.

9, Often pay attention to observe the liquid level in the tank, when the liquid level is too low, the liquid medium should be added in time.

10, Liquid external circulation, customers should pay special attention to the fastness of the connection of the leading pipe, strictly prevent falling off, so as to avoid liquid leakage.

What are the Types of PCB Environmental Tests?

High acceleration test:

Accelerated tests include high accelerated life test (HALT) and High accelerated Stress screening (HASS). These tests assess the reliability of products in controlled environments, including high temperature, high humidity, and vibration/shock tests when the equipment is powered on. The goal is to simulate the conditions that could lead to the imminent failure of a new product. During testing, the product is monitored in a simulated environment. Environmental testing of electronic products usually involves testing in a small environmental chamber.

Humidity and corrosion:

Many PCBS will be deployed in wet environments, so a common test for PCB reliability is a water absorption test. In this type of test, the PCB is weighed before and after being placed in a humidity controlled environmental chamber. Any water adsorbent on the board will increase the weight of the board, and any significant change in weight will result in disqualification.

When performing these tests during operation, exposed conductors should not be corroded in a humid environment. Copper oxidizes easily when it reaches a certain potential, which is why exposed copper is often plated with an antioxidant alloy. Some examples include ENIG, ENIPIG, HASL, nickel gold, and nickel.

Thermal shock and circulation:

Heat testing is usually performed separately from humidity testing. These tests include repeatedly changing the board temperature and checking how thermal expansion/contraction affects reliability. In thermal shock testing, the circuit board uses a two-chamber system to quickly move between two temperature extremes. The low temperature is usually below the freezing point, and the high temperature is usually higher than the glass transition temperature of the substrate (above ~130 ° C). The thermal cycle is carried out using a single chamber, with the temperature changing from one extreme to the other at a rate of 10°C per minute.

In both tests, the board expands or contracts as the board temperature changes. During the expansion process, conductors and solder joints are subjected to high stress, which speeds up the service life of the product and enables the identification of mechanical failure points.
