Test Equipment

Overview

Faulting finding of Printed Circuit Boards (PCBs) can be a difficult process. An easy method to identify short circuits is by using a thermal imaging camera connected to an optical microscope. The live video image can be taken from the camera to a colour display. The product design can be improved by incorporating a low cost MCU, an Embedded Video Engine (EVE) IC, small display and a microscope thermal camera.

Adding an EVE-enabled colour display gives many benefits including:

• Display live video from the thermal camera
• Overlay images with symbols and text
• Provide on-screen menus to make setting up the unit easier
• Use the touch screen to make the user interface more intuitive without additional buttons/dials

​Key Features:​

The following key features of EVE make it ideal for a Thermal Imaging equipment application:​

• Supports a range of screen sizes such as 3.5” up to 10.1”
• Resistive and capacitive touch options available
• Additional RGB to LVDS conversion IC can be used for LVDS displays
• Extensive image support for stylish gauges, background, and symbols
• EVE-attached flash chip support (BT81x) allows image storage independent of the host MCU
• Custom fonts allow multi-language support and symbols/units
• ​Audio output and range of built-in tones for warnings and indicator sounds etc.
• PWM dimming output allows dynamic adjustment of screen backlight brightness
