Accounting Policies [Abstract]
Financing Arrangements [Policy Text Block]	*Financing Arrangements, Non-Cash Activities, & Correction of an Error* The Company previously classified certain licensed tooling software as leased assets and liabilities under ROU assets and financing lease liabilities pursuant to lease accounting under ASC 842, Leases. Upon further analysis, the Company determined these amounts are intangible assets subject to amortization in accordance with ASC 350, Intangibles, Goodwill, and Other and financed through financing arrangements. As a result, the Company corrected immaterial errors to revise its consolidated statement of cash flows for the nine months ended October 1, 2023. Cash payments on notes payable during the nine months ended October 1, 2023 were $0.5 million, instead of presented as payments of finance lease obligations. Proceeds from notes payable during the nine months ended October 1, 2023 were $0.1 million, instead of increases in accrued liabilities and other long-term liabilities. Additionally, $0.5 million was added to the depreciation and amortization adjustment for amortization of software tools financed through financing arrangements for the nine months ended October 1, 2023. Conforming the Company's consolidated statement of cash flows for the nine months ended October 1, 2023 to the Company's reclassification at fiscal year 2023 year-end of certain assets from property and equipment to internal-use software resulted in the reclassification of investing cash outflows from capital expenditures to internal-use software in the amount of $0.3 million. Additionally, non-cash activities of $0.3 million related to deferred charges were removed from the consolidated statement of cash flows. Purchases of assets with financing arrangements were $0.6 million for the nine months ended October 1, 2023. The Company has determined the correction of these errors did not have a material impact on the Company's financial statements, including net income and the balance of accumulated deficit as of and for the nine months ended October 1, 2023.
