In addition, the surfactant contains polyoxyethylene polyoxypropylene alkylamine, an alkyl group of the polyoxyethylene polyoxypropylene alkylamine is CaH2a+1 (where a is 12 to 18). Further, in a case where a number of a functional group of polyoxypropylene of the polyoxyethylene polyoxypropylene alkylamine is set as p and a number of a functional group of polyoxyethylene of the polyoxyethylene polyoxypropylene alkylamine is set as q, the sum of p and q (p+q) is 8 to 21, and a ratio of p to q (p/q) is 0.1 to 1.6."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tin or tin alloy plating solution","description":"A tin or tin alloy plating solution includes: (A) a soluble salt containing at least a stannous salt; (B) an acid selected from an organic acid and an inorganic acid or a salt thereof; (C) a surfactan","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11268203","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.
