How to ensure the quality of SMA connectors?

SMA connectors are small, threaded coaxial connectors for a wide range of applications in the microwave frequency range up to 26.5 GHz. Applications include telecommunication communications, networking, wireless communications as well as testing and measuring instruments. For a commonly used type of RF coaxial connector, product quality is a long-term issue. The process of making SMA connectors requires strict quality control. Ordinary people who buy SMA connectors also need to check whether the product meets quality standards. Here we will take SMA connector RG174 from LenoRF as an example, which is a kind of 4-hole-flange SMA connector.

How to ensure the quality of SMA connectors during the production process

1、During the machining process of the SMA connector, we need to control the through gauge of the product threads. Many companies do not consider this pass-through gauge to be important, thinking that it is sufficient as long as it matches the male and female. But, if the through gauge is not well controlled, it will affect the service life of SMA connector RG174. Some SMA connector products need to be transported back and forth. If you can not control their pass-through gauge well, the contact of SMA connector RG174 may be poor.

2、During the plating process, salt spray control of SMA connector products is also very important to ensure that the products do not suffer from oxidation and corrosion during use, which would otherwise lead to functional failure of the products.

3、During the assembly process of the SMA connector, we need to check 100% of all assembly dimensions to ensure that each dimension is within effective control, so that we can produce connectors with very good performance stability.

4、During the production process of SMA connectors, good PE engineers will also analyze the process of SMA connector products and control the fixture of these products, which can not only improve product quality but also improve the production efficiency of the products.

How to ensure the quality of SMA connectors during the purchase process

1、First, we need to ensure the inspection distance. The distance between the SMA connector RG174 and the eyes of the inspector should be 30 centimeters.

2、Then, we need to determine the inspection time. The inspection time of SMA connector RG174 should not exceed 3 seconds.

3、Additionally, we should check the lighting environment. In the inspection environment, the lighting is standardized to 700-800 lux general office lighting. The distance between the light source and the surface of the SMA connector RG174 is not less than 1 meter.

4、Finally, we should inspect from the inspector's viewpoint. In any inspection situation, the reflection of the inspected SMA connector RG174 should not be directed to the inspector's eyes. During the inspection, the inspector's line of sight is perpendicular to the surface of the SMA connector RG174 being inspected. And the SMA connector product can be rotated along the horizontal and vertical axes. Only through proper inspection, can the quality of SMA connectors be ensured.
