N27 Product Specifications 6.3.2 Moisture N27 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 30°C/60% RH, bake it at a temperature higher than 90 degrees 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.
N27 Product Specifications 7 Mounting N27 onto Application PCB N27 is introduced in a 76-pin LGA package. This chapter describes the N27 footprint, recommended PCB design and SMT information to guide users on how to mount the module onto the application PCB board. 7.1 Bottom Dimensions Figure 7-1 Bottom dimensions of N27 (Unit: mm) Copyright © Neoway Technology Co.
N27 Product Specifications 7.2 Application Foot Print Figure 7-2 Recommended footprint of N27 application PCB (Unit: mm) 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 for LGA inside the module after the second reflow soldering.
N27 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.
