Stamp pastilles

Contrary to the Matrix of balls and Matrix of pins, in this type of connection, the metal barbs and the weldable metal balls are replaced by contactors which make it possible to reduce the size of connection, and thus electrical resistance (what makes it possible to work with moreover high frequencies), and to increase the number of connections on the microprocessor.
