PURPOSE: A releasable connection base for an integrated circuit such as a BGA (Ball Grid Array), a CGA (Column Grid Array), an LGA (Land Grid Array) or a flip-chip, comprising a support with through-holes is disclosed. CONSTITUTION: A metal pin (3) is inserted into each through-hole (13). One end of each pin electrically contacts at least one conductive path (8) of the printed circuit whereas the other end electrically contacts a connecting tab (6) on the mounted electrical component (1) or the other printed circuit. The pins are only loosely longitudinally supported inside the holes (13) between two springs (4, 40) enable slight movement of the pins. The pins may consist of a rod (3) or a spring (3'). The springs (4, 40) may be replaced with a rubber mat containing parallel electrical wires. A radiator (35) holds the integrated circuit on the base.
