Mission and Strategy
- WEC manufactures high-end OEM and ODM electronics products and
systems. WEC provides a total manufacturing solution, being vertically
integrated into PCB supply, plastics and metal parts supply, electronic
assembly, with global procurement, manufacturing, and sales.
- Customers seek cost-reduction and reengineering of first-generation
products. WEC goes through a "three-step" process to cut vendor costs,
production costs, and design costs. Any cost improvement after
production begins is shared 50-50 with customers.
- Sales in 1994 were divided among computers (35%), peripherals
(25%), telecommunications (25%), and other office equipment, medical
electronics, and industrial products (15%). Sales were divided among
North America (55%), Japan (25%), Europe, and Southeast Asia (10%
each). The percentage for 1995 decreased some for North America and
increased for Japan.
- WEC makes Pentium 5 PCBs for NEC in China as an ODM joint
development project to reduce costs; hard disk drives for Conner;
printers; PCB subassemblies for Xerox office equipment worldwide; small
PBXs for Executone in the United States; U.S. cordless and cellular
telephones for Toshiba; and power supplies for ABB in Europe. The
computer sector is decreasing with the growth in other areas.
- The Hong Kong factory was ISO 9001 certified in 1994, the Malaysia
factory was ISO 9002 certified in 1993, and the China factory was ISO
9002 certified in 1996.
