Electrical BOM. Lists components of the route such as connectors, clips, and coverings. (Labeled Circuit Summary.) Lists conductor-wire identification, color, length, and from-to information. Connector tables. Lists the pins and associated wires for the connectors you select. Moving beyond the datasheets, app notes, reference designs, and even in-person tech support that once formed the basis of basic BOMs (still important, of course)--today's electrical engineers can develop a BOM and concurrently test the efficacy of their BOM candidates in real time, thanks to the vast number of plug-and-play development kits.
Phantom items. 3 minutes to read. Contributors. In this article This topic describes, in detail, how the Phantom line type can be used for the lines of a bill of materials (BOM) and a formula.
In the following illustration, (a) is the BOM for product H and parts F and G, and (b) is the route sheet for products H and part F. This illustration shows an example of a BOM structure in two levels. Finished product H represents a product for a machine assembly. The machine assembly consists of two parts, an electrical unit (F) that has two materials (A and B) and a group of packaging materials (G) that also has two materials (C and D). Another material (E) is used during the general assembly of the machine.

The preceding illustration represents the Engineering BOM for product H. This structure provides a good overview of the parts and components of the overall machine assembly.
However, although product designers might prefer to see the BOM represented in this way, this structure might not correctly represent the way that the machine is built on the shop floor. For example, the Engineering BOM in the preceding illustration indicates that electrical unit F is assembled as a separate part on a separate work order.
However, on the shop floor, it might be judged more optimal to assemble the electrical unit as part of the overall machine assembly, not as a separate work order. This Engineering BOM also indicates that part G is a separate part. However, in this structure, part G doesn’t represent a physical part but a collection of packaging materials. Therefore, although an Engineering BOM provides great value for the design of a product and maintenance of that design, it might not be the most logical way to support the manufacturing execution process of the product. By contrast, a Manufacturing BOM represents the best way to build a product. The following illustration shows how the preceding Engineering BOM is transitioned into a Manufacturing BOM.
In this illustration, (a) is the BOM for product H, and b is the route sheet for product H. In this structure, you can see that there is no notion of parts F and G, and the materials that these parts consist of have been elevated to the next BOM level. Unlike the Engineering BOM, which had two operations sheets, the Manufacturing BOM has only one operations sheet. The packaging operation that was linked to part G has also been elevated and is now part of the operations sheet for product H. The assembly of the electrical unit is the first operation. This order makes good sense, because this unit is used in the next operation, which is the machine assembly. The last operation is the packaging operation, which consumes two packing materials (C and D).
In Microsoft Dynamics 365 for Finance and Operations, the transition between the Engineering BOM and the Manufacturing BOM is enabled through the Phantom BOM line type. As the term “phantom” indicates, parts F and G have disappeared during the transition between the two BOM types. In this example, the Phantom line type is applied to the BOM lines for parts F and G in the Engineering BOM. When a production or batch order is created, the Engineering BOM is copied to the production or batch order. Then, when the order is estimated, the transition from the Engineering BOM to the Manufacturing BOM occurs, as shown in the preceding illustrations. From the operations sheet in the second illustration, packaging materials C and D are input for the operation.
Multilevel phantom BOM structures The Phantom line type can be used in multilevel BOM structures, as shown in the following illustration. In this illustration, (a) is the BOM for product G, and (b) is the route sheet for parts E and F and product G. The following illustration shows the resulting Manufacturing BOM and route sheet if the BOM lines for parts E and F are configured so that the line type is Phantom. In this illustration, (a) is the BOM for product G, and (b) is the route sheet for product G. Phantom and route network Phantom BOMs can also be used for a BOM that has a route network. In a route network, one or more operations run in parallel.
The following illustration shows an example of a route network that is used in a multilevel BOM. In this illustration, (a) is the BOM for product G and part F, and (b) is the route sheet for product G and part F, which has a route network. In the following illustration, (a) is the BOM for product G and part F, and (b) is the route sheet for product G and part F.
The term manufacturer takes on many meanings. For a lot of us along the gulf coast, that participate in the oil and gas and marine industries, it usually means custom, low-volume solutions, generally with short lead times. Busy manufacturing floors, packed with projects as varied as the customers. A dizzying array of parts flowing onto the receiving dock in a constant stream of delivery trucks. The general sense of urgency as a group of dedicated technicians and engineers work from the office to the warehouse to the shop floor.
The whole experience is akin to a beehive, bustling and productive. What can make this process more efficient? SOLIDWORKS Electrical offers a variety of solutions.

Manufacturing companies vary widely in what they produce, but they all have one thing in common, a highly skilled workforce capable of interpreting customer requirements, making quick decisions and delivering a quality product on spec and on time with little direction in the form of detailed engineering drawings. So if fully detailed engineering documentation isn’t a requirement for your production process, what is? If the traits reviewed above describe your organization, you’re probably stewing on the answer as you read this article. bill of material (BOM) accuracy. You’re also likely irritated thinking about the last time a basic electrical drawing coupled with an inaccurate, disjointed excel BOM threw your entire production system into disarray.
BOM accuracy isn’t just about delayed delivery. It’s also about lost efficiency and project margin. It’s about the engineer that needs to put down his or her current work and scramble to find parts. It’s about the added expediting fees. It’s about the Sales Representative that now has to have a very unpleasant conversation with a customer.
It’s about the technician who now has to find another project to work on. You don’t need to be a 6 Sigma guru to know the lost productivity involved in rearranging production schedules to keep a technician producing. BOM mistakes affect the entire organization. So how do you balance the need for an accurate BOM with the advantage of having only to produce minimal documentation to produce the desired result? SOLIDWORKS Electrical’s flexible structure provides a suite of tools designed to provide your highly proficient technicians with enough information to meet customer requirements without spending months on the design documentation while maintaining the integrity of the bill of material. SOLIDWORKS Electrical’s one line drawing tools allow an engineer to specify components required for a project, how they are connected, and the general location of the component, without needing to spend time on unnecessary detail. Component tools within SOLIDWORKS Electrical allow the engineer to tie manufacturer specific parts to symbols on the online.
The database-driven drawing updates the BOM automatically when changes are made, mitigating the chance a change to the drawing won’t be picked up in the BOM. Finally, easy to set up macros allow engineers the ability to reuse design data, pulling in both schematic symbols and BOM info. At the end of the day, you need tools that let you do what you do best, produce great products and serve your customers. Let show you how SOLIDWORKS Electrical can provide your production team with accurate bills of materials, without changing how you work.
