FMB110 Datasheet Ver.1.0 7 RF Layout Guidelines The module integrates a multilayer chip antenna to radiate and receive the RF signals. The antenna has been well designed and tuned for common usage but it still needs to have good ground clearance around the antenna to get good RF performance. 1. No ground below antenna region. 2. There should also have a good ground panel and clearance on the main PCB board on which the module is mounted.
FMB110 Datasheet Ver.1.0 guidance on solder re-flow. There are four zones: Preheat Zone - This zone raises the temperature at a controlled rate, typically 1-2.5°C/s. Equilibrium Zone - This zone brings the board to a uniform temperature and also activates the flux. The duration in this zone (typically 2-3 minutes) will need to be adjusted to optimise the out gassing of the flux.
FMB110 Datasheet Ver.1.0 9 Package Figure 7: Plastic Tray Package Modules are packaged in plastic trays and then put into vacuum aluminum bags before shipping. Each aluminum bag might have multiple trays inside depending on the number of the order. There are also humidity indicator card and desiccant pack inside each bag. On each tray there are 60 PCS of modules. The module’s Moisture Sensitivity Level is level 3 in accordance with JEDEC J-STD-020.
