Figure 24: Recommended soldering profile
When soldering leadfree (u-blox 5) modules in a leaded process, check the following temperatures:
o
PB- Technology Soaktime: 40-80sec
o
Time above Liquidus: 40-90 sec
o
Peak temperature: 225-235 °C
AMY-5M modules must not be soldered with a damp heat process.
3.3.4 Optical Inspection
After soldering the AMY-5M module, consider an optical inspection step to check whether:
•
The module is properly aligned and centered
