The Palitronica Anvil Checkpoint is designed to provide general, broad-spectrum defect testing where the testing is designed to detect a wide range of potential defects in a single sweep. Unlike traditional testing methods such as ICT or AOI, if a product passes the initial screening with Anvil, it is deemed free of all defects that the test is capable of identifying. The Anvil Checkpoint provides a clear pass or fail result, allowing you to filter out any fails for further testing if desired and allowing the passes to be shipped-off with confidence.
But this raises an interesting question:
If Anvil detects differences from a "known good" sample, won’t normal manufacturing variations show up as defects?
The answer is both simple and fascinating—yes, and no.
Anvil is so sensitive that it can pick up even the tiniest differences (right down to silicon cracks), creating a "fingerprint" of a specific device that can be identified later. This is where machine learning steps in. The algorithms behind Anvil are designed to distinguish between natural manufacturing variability and actual defects, or even counterfeits. To do this effectively, Anvil needs to be "trained" with samples of known good devices to establish a baseline. This baseline allows Anvil to understand what variations are normal for that particular product.
Could the variability be so high that actual defects get lost in the noise? Unfortunately, yes. In cases like custom, hand-soldered circuit boards, minor defects might slip through, and only the more significant issues would be caught. That’s why it’s important to consider whether a broad-spectrum approach like Anvil is the right fit for your specific needs.
But here’s something crucial to consider: Don’t you want to know what your natural variability is? Understanding this variability isn’t just about avoiding false positives in defect detection; it’s about gaining deeper insights into your manufacturing process. Anvil doesn’t just train for natural variability; it helps you identify and quantify it. By knowing your product’s variability, you can optimize your manufacturing process, ensure consistent quality, and even scorecard your suppliers.
Anvil gives you the tools to not only detect defects but also to understand and work with your product's natural variability, making your testing process more effective and your final product even more reliable.
