Change In Accounting Estimate [Abstract]
Description of change in accounting estimate		Effective December 27, 2010, the Company changed its depreciation method for certain fabrication equipment from the units-of-production method to the straight-line method. The Company considers this change of depreciation method a change in accounting estimate affected by a change in accounting principle. This change in estimate is accounted for prospectively as of the beginning of the third quarter of fiscal year 2011. While the Company believes the units-of-production method, as a function of usage, reasonably reflects the matching of costs and revenues, it requires considerable effort to monitor and track the usage of certain fabrication equipment consistently across all fabrication facilities. The Company believes the straight-line method of depreciation represents a better estimate of the use of the equipment over its productive life and better reflects the pattern of economic consumption. Additionally, the Company believes the new practice is consistent with the predominant industry practice.
Financial effect of change in accounting estimate		The effects of the change described above to net income and earnings per share was immaterial for the fiscal year ended June 26, 2011.
