N51 Product Specifications 6.2 Packing N51 modules are packaged in sealed vacuum bags with dryer, humidity card, and tray on delivery to guarantee a long shelf life. 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.
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.
N51 Product Specifications 7.2 Application Foot Print Figure 7-2 Recommended PCB foot print (Unit: mm) Pin1 Pin74 Pin49 Pin26 7.3 Stencil 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.
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.
