In the manufacturing and quality control industries, there's an old saying: "Only what the eyes can see is considered qualified." As a result, manual visual inspection has become the standard practice in many factories. But have you ever thought about whether this method of relying on the naked eye and experience is still suitable for today's fast-paced production environment?
The answer is: It's long overdue for an upgrade. X ray inspection is ushering in an era of "seeing through everything" for quality control, with efficiency more than 3 times higher than manual visual inspection!
Let's look at a familiar scenario: Before shipping out electronic products, a quality inspector uses a magnifying glass to check each solder joint and circuit for any abnormalities. While this method is simple, it comes with several issues:
Low Efficiency: How many products can one person check in a day? With large orders, inspection speed becomes a bottleneck.
Poor Accuracy: The human eye becomes fatigued, leading to missed defects and misjudgments over time.
Low Reproducibility: Different people may have different standards, leading to inconsistent results.
Can't See "Internal Issues": Defects like solder voids and internal cracks are invisible to the naked eye.
In today's environment that demands "high quality and fast delivery," this level of efficiency and accuracy is clearly insufficient.
The principle behind X ray inspection equipment is quite similar to how hospitals use X rays: X rays penetrate objects, and during this process, materials with different densities absorb the rays differently, creating a contrast image.
Industrial X ray equipment applies this principle to perform non-destructive internal inspections of products. In other words, it allows you to see whether the "internal structure" is intact without having to disassemble or damage the product.
It's like giving the product a CT scan — any issues are immediately visible.
Compared to manual visual inspection, X ray inspection equipment has clear advantages in terms of efficiency:
Automated Scanning, Continuous Operation: Many X ray devices can automatically load products and switch quickly, allowing a single machine to inspect thousands of products continuously.
Fast Inspection Speed: Each product's imaging takes only a few seconds, greatly improving batch inspection efficiency.
Simultaneous Multiple Detail Checks: Solder joints, encapsulation, circuit structures, and even tiny cracks can be detected.
Record Keeping: Images can be stored, making it easier to trace and review them later, enhancing quality control and management capabilities.
Where traditional manual inspection can only handle a few hundred items a day, an X ray system can complete the same volume in just a few hours, and with better accuracy.
While the first thought might be electronics manufacturing, the applications of X ray inspection equipment are far more extensive:
Electronics Industry: Checking solder joints, chip encapsulation, BGA, and other internal structures.
New Energy Batteries: Inspecting whether there are foreign objects or damages inside battery cells.
Automotive Parts: Detecting air holes or cracks in cast parts.
Food Industry: Identifying foreign objects like metal fragments or glass inside packaging.
Aerospace: Checking for internal defects in critical components.
Cultural Heritage & Archaeology: Viewing the structure of artifacts without causing damage.
Essentially, anywhere you need to "see inside", X ray inspection equipment can play a crucial role.
Manual visual inspection is a product of traditional processes. Its advantage lies in its "flexibility", but when it comes to modern manufacturing, which demands large-scale, standardized, and high-precision work, its disadvantages become increasingly apparent.
X ray inspection equipment's essence is transforming the invisible into the visible and turning experience into data, which is one of the core principles of smart manufacturing.
