LED display, The display consists of LED lighting device ( TV backlight LED strips ) and control circuit ( PCB ). The LED display affects the customer’s experience directly,. In addition, the LED display is mass-produced, and quality control is essential. Let me tell you why.

The Type of Backlight:

LCD TVs, according to the different backlights of the LCD screen, The backlight type is: CCFL (Cold Cathode Fluorescent Lamp) and LED two types. 1. CCFL cold cathode fluorescent tube (fluorescent tube) as the backlight, referred to as LCD TV. 2. LED light-emitting diodes are used as backlights, referred to as LED TVs.

Why LED display is more expensive than LCD, the main features:

  1. High brightness: The brightness of outdoor LED display is more than 8000mcd/m2. It is the only large display terminal that can be used all day outdoors. The brightness of indoor LED display is more than 2000md/m2.
  2. Long life: LED life is up to 100,000 hours (ten years) or more, this parameter generally refers to the design life;
  3. Large viewing angle: indoor viewing angle can be greater than 160 degrees, and outdoor viewing angle can be greater than 120 degrees. The size of the viewing angle depends on the shape of the LED light-emitting diode.

LED PCB Strip X-Ray inspection Solution X-1200 can detect following defects:

For TV backlight LED strips, PCB circuit boards:The upper detector and the lower light pipe are synchronously moved, and the stage adopts a fixed structure,Maximum LED strip/PCB circuit board with Length*Width 1200mm*600mm. Lamps, dots, holes and so on. can be effectively detected at any position within this platform.

LED PCB Strip X-Ray inspection Solution

LED PCB Strip X-Ray inspection Solution X-1200, it is Easy to distinguish the gold wire bending and gold wire break of the semiconductor package, and Can detect defects below 2.5 microns with high detection accuracy.

It can accurately measure the interlayer shift of the inner layer pattern of the IC substrate, the mechanical through hole to the inner layer pattern offset, the through hole copper integrity, and the BGA/LGA welding quality inspection function.

The detection space is large (1200mm*600mm), it can accommodate various large-sized samples. The stage can carry 10KG, and Can be placed over large and long LED strips, large PCB board, suitable for electronic products in various fields, Detection speed is 3.0s/test point (excluding loading and unloading movement time).

Suitable for large-scale testing and improve detection efficiency, Because Because of the function of Editable test program for automated CNC inspection. Test parameters for different products can be stored in categories and called at any time.

You can set the detection route or sequence of one or more products, and the program automatically completes the detection and stores the photos.
