ACCOUNTING POLICIES (Policies)	Mar. 29, 2025
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting [Text Block]	The accompanying condensed consolidated financial statements of Sanmina Corporation (the “Company”) have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been omitted pursuant to those rules or regulations. The interim condensed consolidated financial statements are unaudited, but reflect all adjustments, consisting primarily of normal recurring adjustments that are, in the opinion of management, necessary to a fair statement of the results for the interim periods presented. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended September 28, 2024 included in the Company’s Annual Report on Form 10-K filed with the SEC on November 27, 2024. The condensed consolidated financial statements include all accounts of the Company, its wholly owned subsidiaries and subsidiaries in which the Company has a controlling financial interest. All intra-company accounts and transactions have been eliminated. Noncontrolling interest represents a noncontrolling investor’s interest in the results of operations of subsidiaries that the Company controls and consolidates.
Use of Estimates, Policy [Policy Text Block]	The preparation of financial statements requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from these estimates. Results of operations for the second quarter of 2025 are not necessarily indicative of the results that may be expected for other interim periods or for the full fiscal year.
Fiscal Period, Policy [Policy Text Block]	The Company operates on a 52 or 53 week year ending on the Saturday nearest September 30. Fiscal 2025 and 2024 are each 52-week years. All references to years relate to fiscal years unless otherwise noted.
New Accounting Pronouncements, Policy [Text Block]	Recently Issued Accounting Pronouncements Not Yet Adopted In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosure, which will require additional disclosure of certain costs and expenses within the notes to the financial statements. The disclosure requirements are effective for the Company for annual reporting periods beginning in fiscal 2028 and for interim periods beginning in fiscal 2029, with early adoption permitted, and will be applied prospectively, with the option to apply retrospectively. The Company is currently evaluating the impact ASU 2024-03 will have on its financial statement disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which will require the Company, on an annual basis, to provide disclosure of specific categories in its effective income tax rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for the Company in fiscal 2026, with early adoption permitted. The Company is currently evaluating the impact ASU 2023-09 will have on its financial statement disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which will require the Company to disclose information about its reportable segment’s significant expenses and other segment items on an interim and annual basis. The disclosure requirements are effective for the Company for the fiscal year ended 2025, and for interim periods within the Company's fiscal 2026, with early adoption permitted. The Company does not expect ASU 2023-07 to have a material impact on its financial statement disclosures.
Reclassification, Comparability Adjustment	Reclassification Beginning in the first quarter of 2025, the Company changed the presentation of deferred revenue and customer advances, which were previously included within accrued liabilities, to be a separate line item on the condensed consolidated balance sheets. Similarly, a separate line for the change in those amounts is presented on the condensed consolidated statements of cash flows. Certain prior period balances have been reclassified to conform to the current period presentation in the condensed consolidated financial statements and the accompanying notes.
