Do X-ray testing equipment require annual inspection

X-ray detection equipment is an image image projected by X-ray short wavelength light penetrating an object. Technicians analyze the image to determine the defect problem of the object.Generally speaking, the voltage of X-ray detection equipment is mainly 90KV~160kV. The higher the voltage, the stro...

How to distinguish between a three-axis dispensing machine and a four-axis dispensing machine?

What is the difference between a three-axis dispensing machine and a four-axis dispensing machine? I believe many people are not very clear about this issue, but in fact, their differences are not very big. The most commonly used ones are the XYZ axis, which is the XYZ axis. Why are the three axes c...

Explanation of defects in SMT reflow soldering products

The welding defects in SMT reflow soldering products can be divided into main defects, secondary defects, and surface defects. Any defects that result in functional failure of the circuit board after reflow soldering are referred to as major defects; Minor defects refer to defects where the wetting...

X-RAY equipment detects whether there is empty welding or false welding in BGA

Generally speaking, workers in factory workshops are more or less exposed to SMT, and it seems difficult to quickly distinguish whether there is insufficient solder, bubbles, or short circuits in PCBA soldering. Traditional visual inspection or AOI testing cannot effectively determine whether there...

Detailed introduction to the principle and process of reflow soldering

Reflow soldering is the process of soldering components onto a PCB board, which involves surface mounted components. Reflow soldering relies on the action of hot air flow on the solder joint, and the adhesive flux undergoes physical reactions under a certain high-temperature air flow to achieve SMD...

What is the difference between CT equipment and X-RAY 2D detection equipment?

At present, most non-destructive testing equipment on the market is mainly based on two-dimensional image detection. However, for complex product structures, a single angle may obscure defects. Therefore, during testing, it is necessary to rotate the object to be tested in multiple dimensions, which...
