초록

We have developed a cost effective test socket for ball grid array(BGA) integrated circuit(IC) packages using BeCu metal sheet as a test probe. The BeCu furnishes the best combination of electrical conductivity and corrosion resistance. The probe of the test socket was designed with a BeCu cantilever. The cantilever was designed with a length of 450 ${\mu}m$, a width of 200 ${\mu}m$, a thickness of 10 ${\mu}m$, and a pitch of 650 ${\mu}m$ for $11{\times}11$ BGA. The fabrication of the test socket used techniques such as through-silicon-via filling, bonding silicon wafer and BeCu metal sheet with dry film resist(DFR). The test socket is applicable for BGA IC chip.
