Tristate Electronic Manufacturing was founded in 1985 by Ryan Null, of Boonsboro, Maryland. Ryan graduated from Arundel Institute of Technology in 1984 and began work as an electronic instrumentation technician in the telecom industry.
In 1985 Ryan opened Tristate Electronic Manufacturing beginning in the basement of his house. TEM soon moved to a facility on The Old National Pike in Boonsboro, and continued there for 3 years. At that time the electronics industry was dominated by through hole technology requiring most of the assembly work to be done by hand. A wave soldering system and additional production support equipment were added by 1988.
Tristate moved to its present location at 91 Western Maryland Parkway in the Washington County Business Park in 1990, to accommodate growing demands for space and to prepare itself for growth. Tristate began surface mount operations in 1994; began turnkey services in 1995, and added functional test capability in 1998. ISO 9002 certification was first achieved in 1998 and Tristate Electronic Manufacturing is currently certified to the latest ISO 9001:2008 standard.
Our latest accomplishment is achieving ISO-13485:2003 registration for medical device manufacturing in December of 2015.
As Tristate continues to grow we are committed to diversifying our core base of business. We continue to diversify and grow our accounts over multiple industries and are committed to investing in technology and personnel, as the demand requires.
