Teslaman TXR1012 high-voltage power supply has been applied in batches in PCB (printed circuit board) testing
The X-ray detection equipment uses the combination of the X-ray light source and the detector, the X-ray penetrates the detection object, and the detector captures the principle of the fluoroscopic image to detect the internal structure or defect of the object.
X-ray inspection equipment is widely used in the detection of PCB circuit boards. X-rays are used to penetrate the PCB board and obtain images on the imaging sensor to realize perspective projection of the PCB board, which plays a very important role in solving the quality control of component packaging. .
When X-rays penetrate the sample, due to the different absorption of X-rays by different materials, such as tin and lead, these materials can absorb a large amount of X-rays, and the image obtained on the sensor is black, that is, at the solder joints of the solder balls. A black image is formed, and the technician extracts what he wants according to the image and analyzes it to check what defects exist in the product to be inspected.
The advantages of X-ray inspection equipment are mainly reflected in:
1. For high process defect coverage, and can detect defects that cannot be observed by other detection methods at the same time, such as virtual welding, false welding, missing welding, etc., especially for the detection of hidden devices in solder joints;
2. Rapid inspection, for layered or multi-layer PCB boards, only one inspection is needed to complete the defect inspection of double-sided and multi-layered boards.
Teslaman TXR1012 series X-ray high-voltage power supply, as a key component of X-ray generation, is widely used in PCB circuit board X-ray inspection equipment.
TXR1012 is a high-precision X-ray high-voltage power supply with a voltage of 50kV and a power of 50W. It integrates a filament power supply with an output DC voltage of 5V and an adjustable current from 0.3A to 3.5A. The high voltage and the filament current can achieve a linear and stable rise. The TXR1012 series power supply can be connected to a potentiometer to realize remote control of output voltage and current, and has functions such as external voltage and current display, overvoltage and short-circuit protection at high-voltage output terminals, and safety interlock. It also provides remote digital communication interfaces for RS-232, RS-485 and USB communication.
