Signal transmission analysis is investigated for a burn-in socket of fine-pitch ball grid array (FBGA) package using a three-dimensional electromagnetic field simulation. The effects of different signal-ground pin assignments on its signal transmission characteristics are analyzed in this work. Also, its electric and magnetic fields are presented to evaluated their distribution intensity around the signal and ground pins. Its reflection and insertion losses are calculated to analyze the effects

The calculation results for insertion loss and reflection loss show that the frequency characteristics of the burn-in socket are excellent, and that the burn-in socket is suitable for high-speed applications. 483 able to improve the high-frequency characteristics of the burn-in socket and can, therefore, be utilized in high-speed testing applications.
