Quality Assurance Program
Lattice Semiconductor Corporation (LSC) views quality assurance corporate responsibility integral part operational activities. LSC's Quality Assurance organization independent from Manufacturing direct access management, assuring sufficient authority afforded quality issues. LSC's quality program full compliance quality assurance requirements MIL-I-38535B Appendix inspection system requirements MIL-I-45208. also fully certified 9001 standard.
Subcontractor Control
subcontracted manufacturing operations must performed sources exhibiting quality program commensurate that Lattice Semiconductor. suppliers audited least once year monitor their compliance LSC's quality initiatives goals. Incoming inspection performed provide feedback continuous improvement subcontractor performance with main objective being control quality source. Communications in-line data continuously exchanged allow real-time monitoring subcontractor manufacturing operations.
Reliability
products, processes vendors must pass predefined evaluations before receiving initial qualification release. Major changes products, processes vendors require additional qualificaton before implementation. assure continuing conformance reliability goals, ongoing monitor program maintained products.
Document Control
Every product process must have adequate written documentation released available point before production begins. information related definition, manufacturing, testing support products services shall maintained controlled. Initial release well subsequent changes must properly reviewed approved before implemented.
In-Process Control
Qualified product must manufactured under strict quality controls that start with regulated procurement documented inspection plans incoming materials. Sample testing in-line monitoring well statistical process control charts provide constant feedback each critical step manufacturing process.
Nonconforming Material
Material found nonconforming specified requirements identified, segregated, analyzed dispositioned documented procedures. Records maintained denoting nature discrepancy well final disposition. dispositions involve applicable engineering section Quality Assurance. Where applicable, root cause discrepancy will identified corrective action implemented using (Corrective Action Request) form.
Calibration
equipment involved determining product conformance specifications through inspection, measurement testing must required accuracy. Equipment calibrated maintained defined interval against nationally recognized standard. addition, equipment must exhibit suitable indicator showing calibration status well safeguards disallow unauthorized adjustments.
Failure Analysis
Failure modes discovered during qualification testing, inspections, customer returns in-process screening processed through LSC's Failure Analysis group determine cause relevancy failure. Verified failure modes documented corrective action initiated required eliminate root cause.
Training
manufacturing personnel must complete formal training program obtain certification each operation before they allowed perform activities affecting quality. Methods records identifying type extent training maintained recertification required yearly basis.
Corrective/Preventive Action
operational functions utilize documented corrective action system coordinated, recorded monitored Quality Assurance. system designed provide proactive problem identification resolution timely manner. Inputs include vendor, internal customer related problems. Emphasis placed effective elimination root cause prevent recurrence problem.

Quality Assurance Program
Management responsible ensuring that employees have sufficiently well defined responsibilities, authority organizational freedom identify potential quality related problems well initiate implement solutions.
Self Audit
Internal self audits entire quality delivery system performed written procedures predefined schedule. functional audits evaluate actual method written procedure. results these audits documented checklist discrepancies brought attention personnel responsible audited area. Deficiencies require corrective actions must initiated subsequently verified deployment effectiveness. periodic review these functional audit results corrective actions performed Quality Assurance.
Procurement
direct materials services affecting quality reliability product must purchased from qualified sources. Selection these critical suppliers based upon more following: quality system audits, product qualification testing, correlation studies, incoming inspection demonstrated ability. qualified supplier list maintained Quality Assurance used Purchasing control procurement. Each purchase order must specify applicable controlling requirements such direct materials services.
