RF-WM-10AFB1 www.szrfstar.com Ver1.0 - Jan., 2020 5. Assuming that the module is soldered or placed in the Top Layer, it is also wrong to randomly route the Bottom Layer or other layers, which will affect the spurs and receiving sensitivity of the module to some degrees; 6. Assuming that there are devices with large electromagnetic interference around the module, which will greatly affect the module performance. It is recommended to stay away from the module according to the strength of the interference.
RF-WM-10AFB1 www.szrfstar.com Ver1.0 - Jan., 2020 4.7 Trouble Shooting 4.7.1 Unsatisfactory Transmission Distance 1. When there is a linear communication obstacle, the communication distance will be correspondingly weakened. Temperature, humidity, and co-channel interference will lead to an increase in the communication packet loss rate. The performances of ground absorption and reflection of radio waves will be poor when the module is tested close to the ground. 2.
RF-WM-10AFB1 www.szrfstar.com Ver1.0 - Jan., 2020 2. Modules must be placed in anti-static areas. 3. Take the anti-static circuitry (when inputting HV or VHF) into consideration in product design. Static may result in the degradation in the performance of the module, even causing the failure. 4.9 Soldering and Reflow Condition 1. Heating method: Conventional Convection or IR/convection. 2. Temperature measurement: Thermocouple d = 0.1 mm to 0.
