  • Process to create metallic stand-offs on an electronic circuit
    Patent number: 6036836
    Abstract: A process to create metallic stand-offs or studs on a printed circuit board (PCB). The process allows to obtain studs constituted by three successive layers of metal (Cu1, Cu2 and Cu3 or Ni) of which at least the two first layers are made of copper. The height of the so-created stand-off is sufficient to use it in the flip chip technology to assemble chips to a printed circuit board. The present process is implemented according either to the electro-plating (galvano-plating) or to the electrochemical-plating technique.
