  • Publication number: 20240120241
    Abstract: The present invention provides an electrostatic charge detecting packaging device comprising a carrier, multiple dies, and multiple electrostatic-charge-sensitive components; the carrier has a surface; the dies are mounted on the surface of the carrier; and the electrostatic-charge-sensitive components are mounted on the surface of the carrier; since an electrostatic voltage tolerance of each of the electrostatic-charge-sensitive components is lower than an electrostatic voltage tolerance of each of the dies, accumulated electrostatic charges are more likely to discharge towards the electrostatic-charge-sensitive components than towards the dies, and as such, by electrically testing whether the electrostatic-charge-sensitive components are functioning normally when packaging the dies, the present invention allows personnel to debug for knowing which packaging steps exactly cause more serious problems that lead to damaging electrostatic discharges in the dies.
