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.

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.
