Higher Assembly Combination Keyboards
Custom user interfaces range from simple subassemblies to complex higher assembly combination keyboards. Custom designs can result in substantial system cost savings for OEMs in medium to large unit volumes by careful selection of construction techniques, materials, manufacturing processes and electrical interface.
Higher assembly combination keyboards are complete and fully tested for true "bolt-on, plug-in" final assembly. Epec's engineering specialists can suggest user interface solutions that are often overlooked by OEMs by thinking outside of the OEMs' product design experience.
Combination Keyboard Design Elements
Higher assembly combination keyboard have a unified design, which addresses common system requirements such as:
- Physical mounting
- Styling that complements the end application's industrial design elements
- Electronic control of LCD displays, led indicators, and tactile dome switches
- EMI/ESD shielding
- Environmental sealing
- Electronic interface design
Tying all of the major components and requirements together needs attention to component interaction rather than treating the major components as individual items.
Higher assembly combination keyboards reduce OEM costs for procurement and inventory of associated parts and elimination of additional OEM assembly and test cost. Epec helps OEMs move from how user interface keyboards can be designed to how they should be designed to provide the best delivered value.
