Mechanical Engineering create the electronics package that is designed to meet a wide variety of design and project goals. Beyond creating a product compliant to our customer’s design specifications (MIL-STD 810/DO-160), APC products must be designed to be easily fabricated, easily assembled, easily tested, and at the lowest total cost. To meet these goals, APC Mechanical Engineering feature the following capabilities:
- Solid modeling using ProE (Creo/Windchill)
- Vibration analyses using FEA
- Thermal analyses using FEA
- In-house thermal chambers for hot/cold/humidity tests
- Tolerance analysis techniques
- In-house tooling fabrication capability
Performance Under High Vibration
APC designed LCD products are designed to meet a wide variety of high vibration environments. These include MIL-SPEC vibration levels for fast jet fighter, fixed wing with turbo prop, rotary wing and ground vehicle (in cockpit locations).
These high vibration environments can physically stress LCD panels and induce touch mura in the active area of the LCD. To mitigate this effect, APC laminates a cover glass to the LCD to drive up the first natural frequency of the optic. But how much cover glass thickness is required?
APC Mechanical engineers have tested many different lamination configurations for both TN and IPS technology LCD panels and have determined how to accurately analyze these designs using finite element analysis programs.
By testing many different laminated configurations (in LCD size and cover glass thickness) and creating calibrated finite element models that match the measured data, APC has been able accurately model the laminated LCD behavior. Therefore, early in the design phase, APC can ensure that any induced touch mura due to high vibration will not be a problem for the customer.
