Follow the same package method again in case of opened for any reasons. 6.2.1 Tray TBD 6.2.2 Moisture N51 is a level 3 moisture-sensitive electronic elements, in compliance with IPC/JEDEC J-STD-020 standard. If the module is exposed to air for more than 48 hours at conditions not worse than 30C/60% RH, bake it at a temperature higher than 90 degree for more than 12 hours before SMT.Or, if the indication card shows humidity greater than 20%, the baking procedure is also required.Do not bake modules with the package tray directly. 6.3 Storage Temperature: 20C26C Humility: 40% to 60%
Period: 120 days Copyright Neoway Technology Co., Ltd 12 N51 Product Specifications 7 Mounting N51 onto the Application Board N51 is introduced in 100-pin LGA package. This chapter describes N51 foot print, recommended PCB design and SMT information to guide users how to mount the module onto application PCB board. 7.1 Bottom Dimensions Figure 7-1 N51 bottom dimensions (Unit: mm) Pin1 Pin74 Pin26 Pin49 Copyright Neoway Technology Co., Ltd 13 7.2 Application Foot Print N51 Product Specifications Figure 7-2 Recommended PCB foot print (Unit: mm) Pin1 Pin74 Pin26 7.3 Stencil Pin49 The recommended stencil thickness is at least 0.12 mm to 0.15 mm. 7.4 Solder Paste Do not use the kind of solder paste different from our module technique. The melting temperature of solder paste with lead is 35 C lower than that of solder paste without lead. It is easy to cause voiding inside the module after second reflow soldering. When using only solder pastes with lead, please ensure that the reflow temperature is kept at 220 C for more than 45 seconds and the peak temperature reaches 240 C. Copyright Neoway Technology Co., Ltd 14 N51 Product Specifications 7.5 SMT Furnace Temperature Curve Thin or long PCB might bend during SMT. So, use loading tools during the SMT and reflow soldering process to avoid poor solder joint caused by PCB bending. Figure 7-3 SMT furnace temperature curve Technical parameters:
Ramp up rate: 1 to 4 C/sec Ramp down rate: 1 to 3 C/sec Soaking zone: 150 to 180 C, Time: 60 to 100 s Reflow zone: >220 C, Time: 40 to 90 s Peak temperature: 235-250 C Neoway will not provide warranty for heat-responsive element abnormalities caused by improper temperature control. For information about cautions in N51 storage and mounting, refer to Neoway Module Reflow Manufacturing Recommendations. When manually desoldering the module, use heat guns with great opening, adjust the temperature to 250 degrees (depending on the type of the solder paste), and heat the module till the solder paste is melt. Then remove the module using tweezers. Do not shake the module in high temperatures while removing it. Otherwise, the components inside the module might get misplaced.

"This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help."
RF Exposure Information This device complies with FCC radiation exposure limits set forth for an uncontrolled environment. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna shall not be less than 20cm (8 inches) during normal operation. IMPORTANT NOTE:
