Our Mission

Our Mission is to provide services oriented towards satisfying and exceeding our customers’ needs through continuous improvement


Our current facilities, new mini-industrial park, low overheads and personnel, allow us to achieve significant cost reductions in electronics, mechanical, refursh, packaging, and labor-intensive services.

Savings are so significant that projects previously considered uneconomical due to start-up and assembly costs now become feasible.

MicroMex owns its own manufacturing company in Mexico – DEMSA (Diseño Electronico Mexicano S.A. de C.V.) Imuris has approximately 15,000 inhabitants and abundant labor, we are the only industry in the area. The turnover at MicroMex is minimum - less than 5% per year - which is considered outstanding in the industry. High turnover is the major problem faced by the maquiladoras located in the Mexican/U.S. border towns (Tijuana, Mexicali, Nogales, Ciudad Juarez, Nuevo Laredo, etc.). We currently hold employment for over 200 people. Most of our employees have been with us for over 10 years and are diverse in their expertise. MicroMex offers very competitive salaries and benefits and is involved in local community programs for education and sports; this reflects the loyalty and long-term commitment of its employees which in turn leads to experienced personnel working in the manufacture of the products.
