5.8. Notification
Please follow the principles below in the module application.
5.8.1. Coating
If a conformal coating is necessary for the module, do NOT use any coating material that may chemically
react with the PCB or shielding cover, and prevent the coating material from flowing into the module.
5.8.2. Cleaning
Avoid using ultrasonic technology for module cleaning since it can damage crystals inside the module.
