Abstract
An intermediate article of manufacture of a magnetoresistive head with a protective device having sensor elements with terminal pads and a shunt element connected across the sensor element for shunting the sensor element to discharge static electrical charge during the manufacture of the magnetoresistive head. The shunt element is a piece of solder extending between the first and second terminals.

An intermediate article of manufacture of a magnetoresistive head with a protective device comprising:
- a sensor element having terminal pads;
- a shunt element having first and second terminals connected across the sensor element for shunting the sensor element to discharge static electrical charge during the manufacture of the magnetoresistive head, the shunt element further including solder that extends between the first and second terminals;
- and
- a channel located underneath the sensor element, wherein when heat is applied to the shunt element at least a portion of the solder flows into the channel to open the shunt element thereby removing the shunt.
A method for substantially protecting an electronic component from EDS/EOS, said component including a pair of spaced apart leads for conducting current;
- the method comprising the step of:
- applying a conductive element between the pair of spaced apart leads wherein the conductive element, the conductive element including solder and providing a shunt between the pair of spaced apart leads;
- forming a channel underneath the conductive element;
- melting at least a portion of the solder to remove the shunt;
- and
- collecting the melted solder in the channel.
An intermediate article of manufacture of a magnetoresistive head with a protective device comprising:
- a sensor element having terminal pads;
- shunting means connected across the sensor element for shunting the sensor element to discharge static electrical charge during the manufacture of the magnetoresistive head;
- and
- a channel located underneath the sensor element wherein when heat is applied to the shunting means at least a portion of the shunting means flows into the channel to remove the shunt.
A magnetoresistive head with a protective device for discharging electrical charge during manufacture of the magnetoresistive head, comprising:
- a sensor element having sensor terminals;
- a shunt element having first and second shunt terminals connected to the sensor terminal, and further including solder connecting the first and second terminals together for shunting the sensor element;
- and
- a channel positioned adjacent the solder, wherein the channel is configured to collect at least a portion of the solder when the solder is heated to disconnect the first and second terminals and remove shunting of the sensor element.
