Circuit board capable of protecting an MR magnetic head therein against electrostatic breakdown and magnetic head using the same

   
   

The invention provides a magnetic head capable of positively preventing electrostatic breakdown of an MR magnetic head device, and a method of manufacturing the magnetic head. A circuit board comprises at least a pair of leads for constructing a circuit, lands connected respectively to the leads, and solder bumps formed respectively on the lands. The solder bumps are arranged in an adjacent relationship and, when the solder bumps are crushed, peripheral portions of the solder bumps are pressed or spread so as to overlap with each other. The magnetic head includes the circuit board.

La invención proporciona una cabeza magnética capaz positivamente de prevenir la interrupción electrostática de SR. dispositivo principal magnético, y un método de fabricar la cabeza magnética. Un tablero de circuito abarca por lo menos un par de los plomos para construir un circuito, tierras conectadas respectivamente con los plomos, y la soldadura topa formado respectivamente en las tierras. Los topetones de la soldadura se arreglan en una relación adyacente y, cuando se machacan los topetones de la soldadura, las porciones periféricas de los topetones de la soldadura se presionan o extensión para traslaparse con uno a. La cabeza magnética incluye el tablero de circuito.
