Many customers have asked about how to properly handle SMD microphones, such as the 4013 model. To ensure optimal performance and avoid damage, follow these important guidelines before and after PCB assembly.
Before Soldering the SMD Microphone
- Follow the Recommended Reflow Profile: Always follow the temperature curve in the microphone datasheet. The actual temperature must not exceed the specified limits but can be slightly lower.
- Avoid Ultrasonic Cleaning: The microphone's diaphragm is sensitive and can be damaged by ultrasonic pressure.
After Soldering the SMD Microphone
- Do Not Wash the PCB: Cleaning the PCB after mounting the microphone can introduce contaminants or liquid into the component.
- Be Careful with Cleaning Methods: If cleaning is necessary, avoid direct exposure to air guns or cleaning liquids, as they may block the diaphragm's movement.
- Use Tape to Cover the Sound Hole: If PCB cleaning is unavoidable, protect the microphone's sound hole with adhesive tape to prevent liquid intrusion.
- Prevent Cleaning Fluid from Entering: If liquid enters the microphone, it can block the diaphragm's movement, reducing or eliminating audio output.
By following these precautions, you can ensure the stability and performance of SMD microphones like the 4013 model. Proper handling prevents issues related to improper soldering or cleaning methods.
