Section 12IManufacturing Process Specifications Section No.: 12I.2.1.1,Sheet 1 of 4Rev Level:2 Issue Date:4 Aug 2008Live-Uncontrolled on Paper Prepared By:Dan GeitnerDoc #MPS-12I.2.1.1 Additional Distribution:Cable/Harness Assembly Subcontractors Acceptability of Cable and Wire Harness Assemblies 1.Purpose 1.1. The purpose of this specification is to provide a compilation of quality acceptability requirements for cable and wire harness assemblies manufactured by or for Magnetek PCS.This standard is intended to be used by Engineering, Purchasing, Manufacturing, and Inspection in the process of designing, assembling, inspecting, or otherwise evaluating these assemblies. 2.Scope 2.1. This specification establishes acceptability criteria for crimped, mechanically secured or soldered interconnections and the associated lacing/restraining criteria associated with cable and harness assemblies.In general, the acceptability criteria for Magnetek PCS will conform to established industry standards as presented in: IPC/WHMA-A-620; Requirements and Acceptance for Cable and Wire Harness Assemblies. 2.2. Unless specified otherwise, the criteria defined in this standard will correspond to IPC Class 2: Dedicated Service Electronic Products. 3.Support Documentation 3.1. Decisions regarding acceptability must be based on applicable documentation such as contractual agreements, assembly or component drawings, customer or engineering specifications and referenced documents or other standards.In the event of conflict, the following order of preference shall apply: 3.1.1.The purchase order, work order or other statement of customer specification. 3.1.2.The assembly drawings, Bill-of-Materials (BOMs), or other engineering specifications. 3.1.3.Visual inspection work instructions and/or test specifications. 3.1.4.This specification. 3.1.5.The latest revision of IPC/WHMA-A-620. (Class 2) 3.1.6.Standard industry practice or other applicable documents. 3.2. This specification, and other support documentation, will be controlled in accordance with the appropriate Magnetek Document and Data Control Procedures.

Prior to commencement of production all harness/cable assemblies to be approved via Magnetek First Article Approval process. 4.2. Record of approval to be maintained in accordance with the appropriate Magnetek Document and Data Control Procedures. 5.Production Quality Tracking 5.1. Production lot quality data to be tracked via mutually agreed upon quality plan. 5.2. Quality data to be furnished to Magnetek via purchase order requirements and/or Magnetek quality plan. 6.Production Lot Testing 6.1. All cable assemblies and harnesses consisting of more than one conductor to be 100% electrically tested.Test methodology, test coverage, and test electrical requirements to be mutually agreed upon between Magnetek and cable/harness supplier.Cable/Harness supplier to provide Magnetek the test methodology, test procedure, and verification of test results. 6.2. Upon successful completion of electrical test, assemblies to be marked with a Test stamp in accordance with Sec. 7. 7.Marking 7.1. The general specifications for the acceptability of various markings are presented in Section 12 of IPC/WHMA-A-620.Marking provides product and process identification, status, and traceability.At Magnetek PCS, markings and labels have various formats and are utilized for many different purposes.Examples of markings addressed by this standard may include, but are not limited to, the following: 7.1.1.assembly part numbers, date codes, and revision levels. 7.1.2.inspection and test traceability labels. 7.1.3.relevant regulatory agency (UL, etc.) logos and certifications. 7.2. The specification of a marking style and orientation, label material and size, and print formats shall be defined in appropriate BOMs and assembly drawings. 7.2.1.If a marking consists of a stamped number it shall be applied with a non-conductive, permanent ink (not soluble in water or alcohol).

Unless specified otherwise, a marking shall not cover or disfigure another marking.For example, a test label or stamp shall not cover a date code or part number. 7.4. The following marking/labeling criteria are utilized: 7.4.1.The manufacturer shall provide a label on the assembly which shall be permanently affixed to the cable/harness indicating the assembly part number,revision level of assembly, and date code as specified in Section 7.4.2. 7.4.2.Each manufactured assembly shall have a date code.Date code marking shall specify the date of manufacture and production source.This data will appear in a coded format consisting of a four digit number specifying the week and year of manufacture and an alpha designator specifying the source of manufacture. Example: 0305M Manufacturer Year Week Manufacturer Code Alpha Designator The manufacturing code will be supplied on the purchase order in the Vendor Special Instructions area.This code will be furnished by the Process Engineering group and entered into the Magnetek vendor database by purchasing. The following table is maintained in this specification for historical records.
