September 2016 • SMT Magazine 83 the event of nonconformity to specified requirements. Work-Order Information Cell: • Information that describes the work-or- der used to produce the assembly, includ- ing unique work-order name, product ref- erence, planned quantity, process list, the- oretical processing times, scheduled start/ end time, actual start/end time Hazardous Substance Cell: • A list of key elements that make up a ma- terial or assembly which can be used to represent the hazardous content of a ma- terial/assembly/finished product, reduc- ing taxation and recycle costs • List of substance codes and amounts (g, mg, pico grams, etc.) Counterfeit Component Traceability Cell: • The result of visual inspection or auto- mated determination of genuine compo- nents/assemblies. Includes the test or inspection statement, a flag to state whether the determination statement was derived manually or through an automat- ed process and detailed result of visual inspection Material Test Cell: • A list of tests and results for the materi- al or assembly including functional test- ing which can extend across a broad area of unique tests and associated result pat- terns. Information can include pass or fail, single, sample or bulk test, test equip- ment calibration statement, single, sam- ple or bulk test, test name and measure- ment details upper and lower limits as well as measured value Process Maintenance Cell: • Process maintenance events and tasks can have significant effect on the quality of production. Planned maintenance events usually take place between work-orders, so they cannot be tied to a specific pro- duction work-order or product unit. Us- ing the timing of these events relative to work-order execution, however, can aid root cause analysis. Unplanned mainte- nance is usually a breakdown of a process in terms of it not being able to work with- in defined parameters. These cases usu- ally happen during production, resulting in a high risk of effect to the product unit being manufactured, as well as affecting a change between the conditions of the process before and after the maintenance event. Information includes process, date and time for the start and end, planned (scheduled) or unplanned (breakdown) flag, maintenance job code/description the responsible person, parts replaced, re- paired or adjusted, etc. Standard Going Forward The draft document created by the commit- tee is currently going through reviews that in- clude a widening circle of interested parties. It is encouraged for anyone with an interest in traceability to obtain a copy of the draft doc- ument, to read through it and feed comments back to the committee. The committee looks forward to the time, currently estimated as the end of 2016, when the IPC-1782 can start to be used by different companies, creating the opportunity for en- hanced quality, conformance and control of manufacturing, while at the same time acting to reduce the costs of traceability data collec- tion, and bringing value to the manufacturing organisation itself.
