What are the testing items of X-ray

X-ray detectors utilize the penetration ability of X-rays and are generally used in industry to detect internal injuries, breaks, or short circuits in objects that are not visible to the eyes. For example, detecting the presence of short circuits in the internal circuits of a multi-layer substrate, allowing X-rays to penetrate the surface of the substrate and see the internal circuits of the substrate, and having a data receiver opposite the X-ray generator, automatically converts the received radiation into electrical signals and transmits them to the expansion board. These signals are then converted into specific signals in a computer and displayed on a display screen using specialized software, In this way, the internal structure of the substrate can be observed with the naked eye.

With the advancement of technology, circuit boards are filled with smaller and smaller components. Relying on robotic hands for welding also requires solder joint detection to ensure the normal operation of the circuit board. However, the dense solder joints cannot be completely detected by the naked eye, so X-ray real-time detection equipment needs to be used.

So, what are the testing items for X-ray:

1. Defect inspection in IC packaging, such as layer stripping, cracking, cavity, and integrity inspection of wiring.

2. Defects that may occur during the production process of printed circuit boards, such as poor alignment or bridging, as well as open circuits.

3. Detection and measurement of voids in SMT solder joints.

4. Defect inspection for possible open circuits, short circuits, or abnormal connections in various connection lines.

5. Integrity inspection of solder balls in solder ball array packaging and chip packaging.

6. Plastic burst or metal cavity inspection for high-density plastic materials.

7. Dimensional measurement of chips, measurement of wire arcs, and proportional measurement of solder area of components.
