Mounting Considerations
Stencil Design and Solder Paste
A 4 mil stencil and 100% paste coverage is recommended electrical contact pads. The HMC6052 has been tested
successfully with no-clean solder paste.
Pick and Place
Placement is machine dependant and no restrictions are recommended, and have been tested with mechanical centering.
Placement force should be equivalent 1206 SMT components.
Reflow and Rework
No special profile is required for the HMC6052 and compatible with lead eutectic and lead-free solder paste reflow
profiles. Honeywell recommends the adherence to solder paste manufacturer’s guidelines. Irons with a tip temperature no
greater than 315°C should be used.
Application Notes
The HMC6052 Integrated Compass Sensor circuit is composed of two Magneto-Resistive (MR) sensors that sense
external magnetic fields and additional analog support circuits for electronic compass functions. Two instrumentation
amplifiers follow the sensor wheatstone bridges to measure the differential output signals and provide substantial voltage
amplification. A voltage reference is used to center the amplifiers for common zero field bias point. A pair of electronic
switch circuits is included, to create a set pulse function using an external capacitor connected to the SC- and SC+ pins.
In a quiescent state, the capacitor will be charged to the full supply voltage potential and suddenly discharged in reverse
polarity when both SINL and SINH pins flip logic states. The resulting set pulse current flows through the set strap near
the sensor bridge re-aligning the magnetic moments on the bridge magneto-resistive elements. This toggling of the set
strap circuit is on user demand, or periodically to remove any potential magnetic upsets to the sensors.
