Providing test solutions for diverse needs
MJC provides a wide range of solutions that contribute to improving quality and productivity in semiconductor design and manufacturing, from probe cards, testers and wafer probers for the semiconductor wafer test process to test sockets for final testing.
A probe card is used for a go/no-go test of an integrated circuit (IC) on a wafer during the wafer test process in semiconductor manufacturing. MJC's probe cards, featuring superior accuracy and quality, meet the various needs of diverse testing environments.
