<p>A package for an integrated circuit, especially an ASIC, is of the PQFP type and provided with one or more holes therein to engage studs (3, Fig. 1B) on the circuit hoard (2). The studs and holes are sized and positioned accurately to ensure accurate alignment of pins (5) and tracks (6). Electrical connection is ensured by retaining means, e.g. a nut (4) or solder joint, holding the IC on the stud. In another embodiment, the studs (3) are used to provide power supply or earth connections to the intergrated circuit. <IMAGE></p> |
