The first detection pattern and the second detection pattern are provided in a respective one of a first layer and a second layer adjacent to each other such that the first detection pattern and the second detection pattern are opposed to each other. The pads are provided in an outmost layer. Each of the first detection pattern and the second detection includes at least one main segment extending in at least one of first and second horizontal directions and a diagonal direction. A time domain reflectometry connected to a pair of pads detects a misalignment of the PCB by measuring differential characteristic impedance of the first detection pattern and the second detection pattern."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Printed circuit boards and memory modules","description":"A PCB includes a plurality of layers spaced apart in a vertical direction, a first detection pattern and a second detection pattern and pads connected to the first detection pattern and the second det","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11974391","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
