Let's take a common Excel table as an example to see the rich content of the BOM.
The source of BOM information is usually the design departmentThe title bar and detail column information in the complete set of design drawings provided by the door. Sometimes part of the information on the process cards prepared by the process department is also involved. The design BOM is generally summarized at the end of the design, and if there is a large number of borrowed relationships, the design BOM can be basically summarized at the beginning of the design stage, and then the design task is arranged according to the newly generated parts.
Manufacturing BOM information source The general process department prepares the content of the process card, but the design BOM is used as the basic data content. The corresponding electronic view of the product parts is often in the form of an assembly process BOM, and the parts are often specificPCB silk screen layout diagram BOM table, specifications of the protection board, and the corresponding BOM table, storage and transportation warning, etc.); Transportation package drawing, air, sea.
2, CB certification application notes Apply for national difference test: When applying, first explain the country/region to be exported to PNT, so that the certification body can help understand the difference in standards in the country, arrange the difference experiment in time, and avoid the applicant to make up the experiment when applying to foreign certification bodies/testing bodies, delaying the accreditation process and investing more costs. When applying for CB test certificate, you canSeveral factory sites covering the product.
3. CB label (including product name, model, parameters, MADE IN CHINA, Logo, trademark); Other technical data (evaluation after product delivery).
4, Regarding the application for CB test certificate, the following points should be noted: (1) The application for CB test certificate can be submitted by the applicant to any "certification/recognition" NCB covering the product range. (2) The applicant may be either the manufacturer or an entity authorized to act on behalf of the manufacturer. (3) The application may include one or more countriesOne or more factories that produce a product.
5, data and sample review; 2) Officially open the case; 3) Testing; 4) Report preparation; 5) Submit for certification; 6) CB to IECEE registration; 7) Customs clearance of COC goods.
6, lamp with CB certification to submit the data product instruction manual. Safety design documents (including critical structure drawings that reflect climbing distance, clearance, insulation, number of layers and thickness). Product technical conditions (or enterprise standards). Product electrical schematics. Product circuit diagram. List of key components or raw materials (Please select those with the European certification markProduct). Copy of the certificate of the whole machine or component.
The following products require UL certification: lamps, household appliances, communications, power tools, wire and cable, etc. CPC certification CPC certification is mainly for maternal and child products and children's toys wireless charge bom, the main test requirements are as follows: (1) children's products must comply with the relevant rules and safety regulations, mandatory third-party inspection.(2) The examination must be carried out in a CPSC-accredited laboratory.
The UL certification and FCC certification are required. UL Certification: UL Safety Testing Institute is the most authoritative in the United States and the largest civilian organization engaged in safety testing and identification in the world. UL certified products include lamps, household appliances, communications, power tools, wire and cable, etc. FCC certification: The full name of the FCC is the United States Federal Communications Commission, which is the abbreviation of the United States Federal Communications Commission.
DOE certification is the mandatory certification of the United States Department of Energy, and the products in the list must be DOE certification.Such as chargers, power adapters, TV sets, refrigerators, air conditioners and so on. CEC certifies California's energy efficiency standards, and products sold to California need to meet CEC's energy efficiency requirements in order to save energy, improve efficiency and reduce greenhouse gas emissions.
United States as long as your products can meet the relevant standards, there is generally no mandatory requirement to do certification information, the government is not interfere, for such products as power adapters, do certified products, it will be better sales, the United States certification UL TUV ETL can do wireless charge bom! UL price expensive long cycle brand good TUV ETL is relatively cheap short cycle brand is relatively poor.
When the inspection results meet the requirements, the applicant is authorized to use the UL mark. Following IPI, inspectors will visit the factory from time to time to check the product structure and conduct eyewitness experiments. The frequency of inspection is determined by the product type and production volume, and most types of products are inspected at least four times a year (the cost of tracking services is not included in the cost of testing).
1, under the guidance of the standard thinking, the competitiveness of the product and cost control is indeed a pair of contradictions. In the eyes of PVA believers, product competitiveness is a linear value system that adds up to individual configurations, and using more configurations usually means higher BOM costs.
2, the use of computer-aided enterprise production management, first of all, to enable the computer to read the composition of the products manufactured by the enterprise and all the materials involved, in order to facilitate computer identification, it is necessary to use the product structure expressed in the picture into a certain data format,This document that describes the product structure in data format is the bill of Materials, or BOM. It is a technical document that defines the product structure, so it is also called the product structure table or product structure tree.
3, the narrow sense of BOM (Bill of Materials) is usually called "bill of materials", that is, Product Structure. It only describes the simple decomposition of the physical structure of the material according to certain division rules, and describes the physical composition of the material. Generally according to the function of the hierarchy of division and description. BOM in a broad senseIt is a combination of product structure and process flow, and the two are inseparable.
1, spell a lot of fake ten goods must be true. The person who wants to be compensated tenfold must be the person who marked the trademark on the title of the goods. Officials define fake goods as "fake" only when merchants sell fake registered trademark goods and pirated products.
2, spell a lot of fake 10 goods are not necessarily true. The fake one pay ten promise on the Pinduoduo platform is a way to protect consumersHowever, there is no guarantee that all goods bearing this logo are genuine. As an e-commerce platform, Pinduoduo cannot fully control the behavior of merchants, some of whom may intentionally sell fake goods to defraud consumers of their money. Although Pinduoduo will investigate complaints, there are still certain risks.
3. Yes. On the official website of Pinduoduo, it is clearly stipulated that the seller must comply with the genuine product protection policy, which is to promise all buyers that the goods sold are 100% genuine. If the seller violates the regulations, it will bear a series of consequences, including but not limited to consumer complaints, returns and refundsBe punished or even permanently banned, etc., so spell a lot to write false a compensation of eleven hundred genuine goods is true.
4, spell a lot of false 10 is true. Pinduoduo platform is indeed strict in dealing with fake goods, and will cooperate with consumers to properly deal with it. Once the verification certificate is valid, the platform will support refunds, and the seller's selling of fake goods will also be handled. After uploading the certificate, the inspection of the so-called quality inspection department of Pinduoduo official and a series of things, this matter has been delayed for a long time, and the result will only be nothing.
5, since pinduoduo marked "false one pay ten", then we let it false one pay ten. As an ordinary user, our first reaction is naturally to contact the store first. The shopkeeper refused to pay the compensation at first, and after hearing us say that we should contact the platform customer service, he suddenly gave us a refund process in seconds. At this time, we go to contact more official customer service, and we really understand what is the real "playing tai chi".
6, the fake Myanmar jade sold by Pinduoduo is not necessarily real. First of all, consumers should understand that there is a risk of genuine and fake goods in any market, and Pinduoduo, as a large e-commerce platform, is no exception. Although the platform may have a strict audit mechanism and pay ten for one fakeHowever, this does not completely eliminate the appearance of fake goods. Therefore, consumers should be vigilant when purchasing Myanmar jade. Secondly, the jade market itself is very complex, true and false difficult to distinguish.
