Recommended Solder Reflow Profile
NVE recommends the following soldering profile:
300
For leaded (Pb) parts, the peak temperature shown in this profile can be decreased to as low as 230°C.
Exceeding 265°C at peak or the time at peak temperature shown in this profile can damage the parts.
Specifically:
1. AA- and AD-Series sensors are rated at 150°C maximum storage temperature. They can withstand
the solder profile shown above with no harmful effects. However, temperatures above 265°C for
even a brief period or extended periods above 160°C can cause degradation of the GMR sensor
element.
2. AKL- and DD-Series parts contain an on-chip EEPROM. Exposure to temperatures in excess of
265°C can cause EEPROM data corruption, which will cause the parts to fall out of specification.
