3 Hardware Design Antenna Feed Design UM960L just supports feeding the antennal from the outside of the module rather than the inside. It is recommended to use devices with high power and that can withstand high voltage. Gas discharge tube, varistor, TVS tube and other high-power protective devices may also be used in the power supply circuit to further protect the module from lighting strike and surge.
Grounding and Heat Dissipation Grounding and heat dissipation pad Figure 3-2 Grounding and Heat Dissipation Pad The 55 pads in the rectangle in Figure 3-2 are for grounding and heat dissipation. In the PCB design, they must connect to a large sized ground to strengthen the heat dissipation.

In order to prevent falling off during soldering of the module, do not solder it on the back of the board during design, that is, better not go through soldering cycle twice. The setting of soldering temperature depends on many factors of the factory, ...
Figure 5-1 Label Description Product Packaging The UM960L module uses carrier tape and reel (suitable for mainstream surface mount devices), packaged in vacuum-sealed aluminum foil antistatic bags, with a desiccant inside to prevent moisture. When using reflow soldering process to solder modules, please strictly comply with IPC standard to conduct humidity control.
