The cutting machine has a cutting means with a second biggest width that is smaller than the first biggest width of the blind hole, thereby cutting down an individual light source chip without contacting the side edges of the blind hole."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light source chip and a thermally assisted head with the same, and manufacturing methods thereof","description":"A manufacturing method of a light source chip for a thermally assisted head comprises steps of (a) providing a light source bar with a surface coating formed thereon; (b) forming several blind holes o","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537643","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.
