Wiegand module and methods of forming the same

A sensing device comprising:

• a body having a mounting surface so as to be mounted to a substrate having at least a first contact pad and a second contact pad;
• at least one connection structure on the mounting surface that secures the body to the substrate, wherein the connection structure secures the body to the substrate using a particular connection;
• a coil having a center looping portion and an end portion, wherein the center looping portion turns around a coil axis that is substantially parallel to the substrate, and wherein the end portion is oriented in a first direction substantially parallel to the substrate;
• a ferromagnetic element that extends along the coil axis such that the ferromagnetic element is magnetically coupled to the coil;
• and
• a housing on the substrate and supporting the coil such that the coil axis is substantially parallel to but distanced away from the substrate, wherein the coil comprises a center conductive portion, wherein the end portion of the coil comprises a first end and a second end, and wherein the center conductive portion of the coil at the first end comprises a first strengthening portion to be directly attached to the first contact pad and the second end comprises a second strengthening portion to be directly attached to the second contact pad to establish a first electrical connection between the first end and the first contact pad and a second electrical connection between the second end and the second contact pad.

A package comprising:

• a body having a mounting surface so as to be mounted to an external surface;
• at least one connection structure on the mounting surface that is configured to secure the body to the external surface, wherein the connection structure secures the body to the external surface using a particular connection;
• a coil having a plurality of turns around a coil axis,
• a first end of the coil being oriented in a first direction substantially parallel to the mounting surface such that the first end is attachable to the external surface, wherein the first end of the coil comprises a strengthening portion configured to be directly attached to the external surface;
• at least one recess in the mounting surface that allows for the first end of the coil to exit the body for connection of the first end to the external surface;
• and
• a ferromagnetic element that extends along the coil axis such that the ferromagnetic element is magnetically coupled to the coil,
• wherein the body is configured to house the coil and the ferromagnetic element and the body is configured to support the coil such that the coil axis is substantially parallel to, and distanced away from, the external surface.
