Virtual soldering is the most common circuit failure of PCB board. It means that the surface of the soldering parts does not have sufficient tin layer, and the soldering parts are not firmly tinned, causing the phenomenon of tin peeling. Generally, there are the following reasons : 1. In the production process, improper production technology (such as less tin, unstable solder joints, solder ball spots containing bubbles, etc.), resulting in unreasonable conditions; 2. Production equipment in the process of long-term use Aging, thereby affecting the firmness of solder joints.
So how does X-ray inspection equipment judge whether it is a false welding?
There is a core component in X-RAY inspection equipment, that is X-ray tube. This light tube mainly produces X-rays. Through the principle of X-rays, it can observe the inside of the inspection body through the workpiece. X-RAY detection equipment uses X-ray tube as a ray source to emit X-rays through the PCB printed circuit board, and the flat-panel detector receives images, and finally the software performs imaging display.
It is safer to use X-RAY testing equipment for PCB virtual solder detection. X-RAY testing equipment can detect other PCB defects, such as PCB bubbles, missing solder, and other defects that are invisible to the naked eye.
In order to meet the needs of customers for X-ray inspection, BETON PCB has launched a new online X-Ray inspection system with beautiful appearance, large inspection area, strong resolution and high magnification. The system uses a closed ray source and a flat-panel detector as the core components and has a good detection effect. It is suitable for testing in special industries such as semiconductors, packaging components, electronic connector modules, and photovoltaic industry. Accurately detect cracks or defects in metal materials or components, with high-definition imaging, and high-precision detection of virtual welding. It is worth buying with confidence.
