What does BOM list mean? The BOM list needs to contain a lot of information, but the information required in it does not seem to be significantly different from the product parts list we are familiar with, but it is not. The content required by the BOM list is relatively more detailed. Today, the car wireless charging PCB factory will provide you with some reference. How much do you know about the difference between the BOM list and the product parts list?
1. Each material on the material list has its unique code, that is, the material number, which is very clear about the material it consists of. General parts show schedules do not have such strict regulations. Parts lists attached to individual products do not necessarily allow for unique enterprise-wide material codes.
2. The hierarchical relationship of parts and departments in the bill of materials must reflect the actual assembly process. Some assemblies on the drawings may not appear in the actual assembly process, but may also appear in the bill of materials.
3. The bill of materials should include the raw materials, blanks and some consumables required for the product, and the yield should also be considered. The parts list does not include materials that do not appear on the drawing, nor does it reflect the consumption quota of materials. The BOM is mainly used for planning and control, so all planning objects can be included on the BOM in principle.
4. According to the management needs of the automobile wireless charging PCB factory, several different shapes of a part, such as casting and forging blanks and processed parts, processed parts and repainted parts of different colors, must be included in the bill of materials. Give different codes to distinguish and manage. Parts lists are generally not treated this way.
5. What material should be hung on the bill of materials is very flexible and can be completely defined by the user. For example, processing a stamping part requires a special mold in addition to the raw material steel plate. When establishing the bill of materials, you can hang the mold as an outsourced part in the lower layer of the stamping part. The relationship between it and the number of stamping parts is the mold consumption quota.
6. The order of a parent component and sub-components in the bill of materials should reflect the assembly order of each component, and the order of the part numbers on the parts list is mainly for the convenience of viewing the drawing.
From the above six points, it is not difficult to see that the BOM list is more strict than the ordinary parts list, but it is also more flexible and free. This is also one of the convenient services that the automotive wireless charging PCB factory can provide to customers today. The purpose is to allow customers to choose the components they want more freely and flexibly for mounting.
