26 SMT007 MAGAZINE I APRIL 2020 3. Lifecycle Includes details of the product shipping, application, and usage, comprising market data, such as repair, all the way to ultimately recycling. Information is included to connect products should they be combined with oth- ers, such as in the case that a product becomes a sub-assembly of a larger product. Each cell within the IPC digital twin is iden- tified by a unique name and has an indexed table of contents that declares the data con- tent and the degree to which the data has been populated and confirmed. Each application using data from the IPC digital twin will know exactly what data is available, how reliable it is, and any gaps that may need to be populated before any processing of the data can be done. There are literally hundreds of different use cases of digital twins throughout the holistic manufacturing process to which the IPC digi- tal twin standard will be applied. With known and established standards utilized where pos- sible, new open formats will be created where necessary to fill in gaps. Data structures are likely to be encoded using XML or JSON. There may be multi- ple choices of data formats in certain cells if there are multiple standards suitable and applicable, including in the area of 3D visual model representation, for example. A typical use-case exam- ple that illustrates the true power of the digital twin at the highest level might be as follows: 1. An EMS company receives an IPC digital twin from a customer as part of a request for quotation, representing a range of products. The customer requires infor- mation about the unit cost of manufacturing versus quantity, lead- time, choice of manufacturing locations, a commitment to quality, and information about materials. 2. The EMS company has an IPC digital twin of its manufacturing organization that includes several sites. Each site has many production lines and cells. 3. The EMS quotation team has an applica- tion that takes the product digital twin from the customer and processes it against their internal manufacturing digital twin. 4. Questions and responses are triggered from this application to multiple sub-appli- cations, that may, for example, go into the different associated areas of manufactur- ing, down to increasing levels of detail. External systems such as MES and soft- ware associated with specific equipment may also be automatically contacted dig- itally as part of the process. Sub-applica- tions work together to provide the data that contribute to the analysis. Some will assess which production configurations
