CORINTH, MS — KeytronicEMS plans to invest $500,000 in its facility here, adding 75 jobs over the next three years.

The EMS said it would add a new production line to the site, which at 350,000 sq. ft. remains one of the largest in the US. Funding is coming in part from grants made by the Mississippi Development Authority, which is covering 70% of the investment.

Employment will jump by a third from the current headcount of 230.

KeytronicEMS is the world’s 40th largest EMS/ODM company, according to the CIRCUITS ASSEMBLY Directory of EMS Companies.
