Abstract
A system includes a printed circuit board (PCB) having multiple bonding sites and a packaged integrated circuit (IC) having multiple conductive portions for electrically contacting respective bonding sites when the IC is mounted thereon. A portion of the package is formed of a magnetic material. The system also includes a magnet to controllably induce a magnetic field at the PCB having a strength sufficient to attract the magnetic material provided in the IC package and to hold the packaged IC onto the PCB. The system also includes a testing unit for evaluating the PCB and packaged IC while the packaged IC is held onto the PCB by the magnetic field induced by the magnet. The IC package comprises a semiconductor IC chip encapsulated within a casing and a lead frame electrically coupled to the semiconductor IC chip. The lead frame includes the magnetic material.
