XY-MBA32A Bluetooth Module Data sheet 8 Mounting Suggestion You can refer to the following references for the mounting design of the module with an onboard antenna (XY-MBD58B with PCB antenna). Recommended module mounting example: Please do not place any metal components in blue shaded space (*1), such as signal line and metal chassis as possible except for the mainboard while mounting the components in *1 space on the mainboard is allowed except for no copper plating area (*2).
XY-MBA32A Bluetooth Module Data sheet The ground plane shall be at least 5 mm from the edge of the antenna area of the module. All module GND pins MUST be connected to mainboard GND. Place GND vias close to module GND pads as possible. Unused PCB area on a surface layer can be flooded with copper but place GND vias regularly to connect copper flood to the inner GND plane. If GND floods the copper underside the module then connects with GND vias to the inner GND plane.
XY-MBA32A Bluetooth Module Data sheet Placement of resin or plastic parts: Placement of metal parts The minimum safe distance for metal parts without seriously compromising the antenna (tuning) is 40 mm top/bottom and 30 mm left or right. Metal close to the module antenna (bottom, top, left, right, any direction) will have degradation on the antenna performance. The amount of that degradation is entirely system-dependent, meaning you will need to perform some testing with your host application.
