Coupling an electrical connector to a printed circuit board (PCB) involves disposing forms of conductive bonding agent on the PCB, pressing spring-loaded power pins of an electrical connector towards a surface of the PCB, heating the forms of conductive bonding agent, thereby at least partially melting the forms, pressing the spring-loaded power pins into the melted forms of conductive bonding agent, and holding the power pins in the forms until the forms have cooled enough to form a bond that holds the power pins, thereby forming an electrical connection between the one or more pins and the PCB. The spring-loaded power pins are configured to automatically lift away from the surface of the PCB when the bond is weakened.

Automatic power disconnect method

Systems and methods are disclosed for automatically disconnecting a power source in an electronic device. A data storage device is disclosed comprising a printed circuit board (PCB) and an electrical connector secured to the PCB, the electrical connector including a power pin having a power input contact portion configured to receive power from a communication interface connector, a substantially straight portion connected between the power input contact portion and a bend in the power pin, and an output arm connected between the bend at a first end and a power output contact portion at a second end, the power output contact portion being configured to be electrically coupled to the PCB via an electrical connection medium. The bend causes the output arm to lift away from the PCB when a bond between the power output contact portion and the electrical connection medium is broken.

Automatic power disconnect device

A data storage device coupled to a host power supply is disclosed and includes a spindle motor and Voice Coil Motor (VCM) circuitry, a power device coupled to the host power supply via a first host supply line and coupled to the spindle motor and VCM circuitry, wherein the power device comprises a first voltage rail, a first isolation circuit, and control circuitry, wherein the power device receives a first supply voltage on the first voltage rail via the first host supply line and provides the first supply voltage to the spindle motor and VCM circuitry via the first isolation circuit, and wherein the control circuitry is operable to monitor the first voltage rail for an overvoltage event and, when the overvoltage event is detected, control the first isolation circuit to disconnect the spindle motor and VCM circuitry from the first voltage rail.
