Electronic products in each time to find PCBA foundry production processing, customers need to provide a BOM bill of materials, and now basically will require BOM bill of materials to standardise the integrity. Today iPCB give you a specification of the BOM bill of materials in the PCBA processing how important.
BOM bill of materials refers to the bill of materials, PCBA processing will require customers to provide the latest BOM bill of materials before the BOM bill of materials contained in the production of all the electronic components and other materials required for the product, PCBA foundry manufacturers need to be based on this BOM bill of materials for customers to purchase materials for production, while the financial sector will also be based on the BOM bill of materials to calculate the cost of production, manufacturing departments will also be based on the BOM bill of materials to calculate the cost of production. At the same time, the finance department will also calculate the production cost according to the BOM bill of materials, and the manufacturing department will also regard the BOM bill of materials as an important production basis. Therefore, a standardised BOM is very important.
BOM Bill of Materials
A standard BOM bill of materials should contain the material code, material name,material specifications,dosage,organisation, etc.,which can clearly and intuitively see the specifications and dosage of each material.
Many electronic engineers provide a BOM bill of materials that lacks a precise definition of the material's brand and manufacturer's code, or the manufacturer's code is missing part of the tail code,resulting in the PCBA foundry may be in accordance with the default selection of a conventional series of materials. In many cases,the series of ICs with different end codes may represent subtle differences in application,packaging piping,voltage and current ratings, packaging, etc. This irregularity in the BOM material definition has led the PCBA foundry to select a regular series of materials by default.This kind of irregular BOM material list will lead to the production of PCBA boards may have some functional failures or failures in a particular application environment, troubleshooting is extremely difficult.In view of this,it is highly recommended that electronic engineers standardise the brand,manufacturer code,description and packaging of each material and other extremely important information. In this process, reference can be made to public platforms such as Digikey and Mouser.
Because the R&D and production of electronic products are repeatedly calculated and updated, and will be constantly promoted to optimise the product,in this process,the BOM will also be updated with the BOM, even if it is an update of a piece of material,it will have an immeasurable impact on the product.Therefore, after each update,the old BOM must be marked as out-of-date and sealed to stop using it.To ensure orderly version and model management, the BOM list of the product must be issued by the R&D department and used online,at least by the R&D engineer and the head of the R&D department at each level of signing to confirm to ensure the correctness of the BOM list. Then we should contact the PCBA OEM in time to provide the new BOM to the PCBA manufacturer to avoid the situation that the BOM has been updated, but the product is still purchased and produced according to the old BOM.
Therefore, a standardised BOM is extremely important for material procurement, PCBA foundry, ERP system entry and financial costing.
