is a family owned and operated electronic contract manufacturing company. The Du family, headed by Xuong and his wife Trinh, emigrated to the United States from the former Republic of Vietnam in 1979. Once in the United States, the family settled in North San Diego County, California. Eldest sons David and Co Kien immediately began work in cable and harness manufacturing in a Vista, CA company.

In 1981, the harness and cable operations of Southwest Assembly were spun-off into Southwest Wire & Cable, also in Vista, CA. David, Co Kien and later Danny, a third son, rapidly rose to positions of responsibility at Southwest Wire & Cable under the leadership of General Manager Chuck Rabel. David became the production manager, Co Kien and Danny, Production Supervisors, while Southwest Wire & Cable successfully serviced the cable and harness needs of customers like NCR, Xerox, Rainbird Sprinklers, and major video game manufacturers.

In 1988, after the take-over by SCI of Huntsville, AL, a significant number of long-term customers moved their business to competitors which resulted in personnel cutbacks. David and his brothers saw this as an opportunity to go into business for themselves in a field in which the Du family was expert.

In September of 1988, DDH was established with initial capitalization coming from hard earned family savings. DDH was originally located in a leased 2,000 square foot facility in San Marcos, CA. In 1991 DDH moved to a larger facility on Progress Street in Vista, California. With steady growth the company increased its facility to 5,300 square feet in 1992, and then purchased the entire 10,800 square foot building in 1993.

In 1994 Chuck Rabel, former associate and client while heading Avnet's cable assembly operation, joined DDH as General Manager. One of his initial decisions was to get the company running on an MRPII system. He managed the installation and implementation of the selected system (Add + On, from Open Systems). This system has been upgraded and customized over the yeras to best serve DDH's unique operations.

In 1996, to meet ever-growing demands and provide capacity for further growth, DDH purchased and relocated operations to it's current 42,000 square foot facility in Vista, California.

Over the years, DDH has grown to become one of the largest, most capable and automated cable/wire harness manufacturers in Southern California. In February 1998, DDH separated from most of it's competition when it became certified ISO 9002-1994. This world class quality system standard has become the benchmark for manufacturing organizations.

Through dedication to servicing clients, reinvestment of earnings and productive hard work, the Du family and the DDH team are a true American success story. As of this writing, the team is 145 strong, representing 11 countries.

In mid-2000 David and Danny Du started up Dutek, a sister company, to service key clients' requirements for printed circuit board assembly. 2000 also saw dramatic growth in DDH's mechanical assembly business.

In early 2001, DDH purchased a 37,000 square foot facility in Vista. This new manufacturing operation (Plant 8), specializes in mechanical assemblies (panels and boxes) using printed circuit board sub-assemblies from Dutek and wire and cable assemblies from the main DDH plant.

Also in early 2001 DDH opened an operation in Xiamen, China to be able to service clients with medium to high volume assembly requirements. In August 2006 DDH will occupy a new 67,000 square foot facility in Xiamen, China.
