What external environmental factors will affect the first SMT tester

As a high-precision precision instrument, any small external factors may bring measurement accuracy errors, then which external factors have a greater impact on the instrument, should be understood and paid attention to? The following Xiaobian to give you a detailed introduction.

1. Ambient temperature

As we all know, temperature is the main factor in the measurement accuracy of the first tester, because the first tester is a precision instrument, so some of the production materials will be affected by thermal expansion and contraction, such as grating ruler, marble and other parts. Generally, there are strict requirements for the measurement of temperature, and the temperature is generally floating two degrees above and below 20 ° C, and there will be some changes in the accuracy beyond this range.

Therefore, the machine room using the first tester must be equipped with air conditioning, and pay attention to the use of air conditioning. An air conditioner should be able to turn on 24 hours, otherwise try to ensure that it is on within 8 hours of work; Second, ensure that the first tester is used under constant temperature conditions, and then measure after the temperature of the machine room is stable; Three air conditioning mouth do not blow against the instrument.

Second, environmental humidity

Many companies may not pay attention to the impact of humidity on the first tester, because the instrument has a large range of acceptable humidity, and the general humidity can be between 45% and 75%. However, it should be noted that many parts of precision instruments are easy to rust, and once rust will greatly cause precision error. Therefore, pay attention to air humidity control and try to keep the equipment in a more suitable humidity environment. Pay attention especially during the rainy season or in areas that are already wet.

3. Environmental vibration

Vibration is a common problem for the first tester, and it is difficult to avoid air compressors, presses and other heavy equipment with large vibrations. Attention should be paid to controlling the distance between these vibration sources and the first tester. There are also some small amplitude vibration sources that need attention, and if the small amplitude is close to the vibration frequency of the first tester, it is a very serious problem.

However, enterprises generally install shockproof equipment on the first tester, so as to reduce the interference of vibration on the first tester and improve the measurement accuracy.

4. Environmental health

The first tester this precision instrument has high environmental health requirements, if the health is poor, dust and dirty things will be left on the first tester and measurement workpiece, which will lead to measurement errors. Especially in the working machine room there are some oil, coolant, etc., be careful not to let these liquids stick to the workpiece.

Usually pay attention to cleaning the machine room health, in and out of the personnel should also pay attention to health, to wear clean clothes, in and out to change shoes, reduce the outside dust oil stains into the machine room.

5. Other external factors

There are also many external factors that may affect the measurement accuracy of the first tester, such as the power supply voltage, etc., the first tester needs a stable voltage when working, and the general enterprise will install equipment to control the voltage, similar to a regulator to control the voltage.

The above content is the introduction of what external environmental factors affect the first tester, the first tester is based on the CCD digital image, relying on the computer screen measurement technology and the powerful software ability of space geometry. After the computer is installed with the special control and graphic measurement software, it becomes the measurement brain with the software soul, which is the main body of the whole device.
