FIGURE 4-13:
RECOMMENDATIONS FOR THE PLACEMENT OF THE MODULE ON THE HOST
PCB BOARD
4.5
Soldering Recommendations
The RN4870/71 Bluetooth modules are assembled
using standard lead-free reflow profile IPC/JEDEC
J-STD-020.
The module can be soldered to the host PCB using
standard leaded and lead-free solder reflow profiles.
To avoid damaging the module, the following recom-
mendations are given:
• Microchip Technology Application Note, “AN233
Solder Reflow Recommendation” (DS00233)
provides solder reflow recommendations
•Do not exceed peak temperature (TP) of 250°C
• Refer to the solder paste data sheet for specific
reflow profile recommendations
• Use no-clean flux solder paste
•Do not wash as moisture can be trapped under
the shield
• Use only one flow. If the PCB requires multiple
flows, apply the module on the final flow.
