  • Page 27: Process Information

    5.1. Delivery ME70-169 modules are delivered in plastic tray packaging, each tray including 50 units. The dimensions of the tray are the following: 329 mm x 176 mm x 5.6 mm. Each unit is placed in a 26.6 mm x 16 mm location. An empty tray weights 45 g and a loaded tray weights around 130 g.

  • Page 28: Storage

    Soldering pad pattern The surface finished on the printed circuit board pads should be made of Nickel/Gold surface. The recommended soldering pad layout on the host board for the ME70-169 is shown in the diagram below: All dimensions in mm Neither via-holes nor wires are allowed on the PCB upper layer in area occupied by the module.

  • Page 29: Solder Past

    5.6. Soldering Profile (RoHS Process) It must be noted that ME70-169 module should not be allowed to be hanging upside down during the reflow operation. This means that the module has to be assembled on the side of the printed circuit board that is soldered last.
  • Page 30 CAUTION - It must also be noted that if the host board is submitted to a wave soldering after the reflow operation, a solder mask must be used in order to protect the ME70-169 radio module’s metal shield from being in contact with the solder wave.

  • Page 31: Board Mounting Recommendation

    6.2. Power supply decoupling on ME70-169 module The power supply of ME70-169 module must be nearby decoupled. A LC filter is strongly recommended in case of DC-DC conversion. It must be placed as close as possible to the radio module power supply pin, VDD.
