Precautions for using the sim card connector

                               Precautions for using the sim card connector
1. The sim card connector is directly operated by humans. Please do not use it for the mechanical detection function.
2. For the mounting hole pattern of the printed circuit board, please refer to the recommended dimensions recorded in the product drawings.
3, can not be cleaned.
4. Please be careful not to apply external force during the combined installation process of MINI SIM card connectors such as thin switches.
5. When used under low voltage conditions (below DC1V), there may be poor contact. Please confirm separately when using this condition.
6. When soldering, the water-soluble flux may corrode the SIM card connector product, please avoid trial.

7. When soldering the solder pins of the SIM card connector, if a load is applied to the solder pins, there may be loosening, deformation and 

deterioration of electrical characteristics due to different conditions. Please pay attention during the trial.

8. Please do the soldering twice after the first soldering part returns to normal temperature. Continuous heating may cause deformation of the 

peripheral part of the SIM card connector, loosening or falling off of the solder pins and the possibility of lowering the electrical characteristics.

9. The setting of welding conditions should be carried out according to the actual conditions of mass production.
10. Avoid flux flow from around the printed circuit board to the SIM card connector product.
11. Products with mounting screws should be tightened within the specified torque to avoid the possibility of thread damage.

12. This product is designed and manufactured on the premise of DC resistance and load. Please confirm separately when using other loads 

(inductive load, capacitive load).

13. During use and testing, if the load exceeds the specified load, the switch may be damaged. Please kept informed!

14. Please install the product to the specified installation surface and make the installation reach a level state. If it cannot reach the level state, it 

will cause poor operation.

15. If it is used in a dusty environment, dust will enter from the opening, resulting in contact failure or poor operation. Please consider it in advance

 when designing.

16. If it is used in an environment containing corrosive gas, it may cause poor contact and other phenomena. Please consider it in advance when designing.
