Note on Lead-Free Packages The electronics industry has been working to provide lead-free products in response to concerns about the environmental impact of the use of lead (Pb) in solder finishes. Increasing customer demand and directives to decrease the amounts of lead in consumer electronics products from governments around the globe, drives this effort. Lead-free finishes utilizing pure tin (Sn) have already been qualified at NVE and are available in most of our products. However, additional lead times are associated with these parts. Since most lead-free solders being used in board assembly environments have higher melting temperatures than traditional tin-lead solders, higher reflow temperatures may be necessary to form an equivalent solder joint between the component and the PC board. NVE characterizes all lead-free packages using elevated temperature (245C to 260C) reflow profiles characteristic of lead-free board assembly environments. All lead-free products will be identified with an "E" suffix on the part number and a lower case "e" marking on the package. This lead-free transition is an important component of NVE's commitment to take an active part in protecting the environment and our responsibility to our customers and the communities around the world in which we do business. We remain dedicated to meeting our customers' requirements and expectations. - 133 www.nve.com phone: 952-829-9217 fax: 952-829-9189 Appendix 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 230C. Exceeding 265C 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 150C maximum storage temperature. They can withstand the solder profile shown above with no harmful effects. However, temperatures above 265C for even a brief period or extended periods above 160C 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 265C can cause EEPROM data corruption, which will cause the parts to fall out of specification. - 134 www.nve.com phone: 952-829-9217 fax: 952-829-9189 Appendix Magnet Data NVE supplies Ceramic 8 magnets in some of our GMR sensor evaluation kits.

Differential: The field difference between the Operate Point and the Release Point. Electrical Offset: The inherent imbalance of the bridge expressed in differential voltage output. HBM: Human Body Model for ESD specifications. Hysteresis: The maximum deviation in volts between the output with increasing field and the output with decreasing field, where the applied field is unipolar (applied in either a positive or negative direction, without crossing the zero field point), divided by Voltage Span.
