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.
8.3. Packaging
BG772A-GL is packaged in a vacuum-sealed bag which is ESD protected. The bag should not be opened
until the devices are ready to be soldered onto the application.
The following figures show the packaging details, measured in millimetre (mm).
