BOM is the abbreviation “Bill of Material”. It is mean a product processing needs to use all the materials list. So the BOM list is very important for SMT processing factory, contains the entire product processing process of important information.
As the BOM list provided by the customer is not perfect, the general SMT processing plant need to be converted internally into the form of internal company documents for distribution, then the SMT chip processing plant to organize the BOM list what are the considerations?
SMT patch BOM list organization notes:
1, The BOM list contains: process procedures, material code, material name, description, brand, bit number, dosage, notes.
2, The SMT chip processing and DIP plug-in processing components used to organize the classification open, to facilitate the production process of each process at a glance.
3, The description must be clear, including the model, package, resistance and capacitance value size, etc..
4, There are some vital electronic components, customers hope that SMT chip processing plant in accordance with the specified brand to purchase. At the same time, taking into account the fluctuations of the component market and the cost, when necessary, you can choose alternative models for the note.
5, Check whether each bit number and the number of consistent, check whether the coordinates and bit number completely overlap.
6、Distinguish the coordinate value needed for the front and back according to the coordinate T/B.
SMT placement processors are able to compile a standard error-free BOM list, which is the benchmark to ensure the accuracy of product processing. Without a perfect BOM, it is impossible to manufacture PCBA with quality assurance, so the accuracy of BOM is very important.
Grande specializes in providing overall PCBA electronic manufacturing services, including PCB design, upstream electronic components procurement to PCB production and processing, SMT placement, DIP plug-in, PCBA testing, finished product assembly and other one-stop services.
The company gives full play to its competitive advantages in scale procurement and quality control, and has signed long-term cooperation agreements with many domestic and global electronic component manufacturers to ensure the quality and stable supply of raw material sources and transfer the benefits to customers.
Long-term procurement advantages in IC, resistors, capacitors, inductors, diodes and other components can greatly save customers’ inventory costs, improve production turnaround efficiency and save time. At present, we provide PCBA processing services for customers in USA, UK, Japan, Russia, France, Canada, Australia, Romania, Switzerland and other countries and regions.
We provide PCBA processing services, starting from PCB board fabrication, our own PCB manufacturer (with extremely strict TS16949 certification for the automotive industry), focusing on the quality of the board and PCBA quality control system.
Due to decades of experience in procurement of electronic components, we maintain long term cooperation with large brands to ensure the original packaging of components and procurement channels. In the encapsulation process of components, we choose Senju and Loctite solder paste to ensure the reliability of the soldering, with automatic printing machine, Panasonic high-speed placement machine, upper and lower eight temperature zone reflow soldering, AOI automatic optical detector, etc., which can effectively ensure the reliability and quality of the electronic packaging process.
In addition, the perfect management process of IPC, IPQC, OQA, etc., with clear job responsibilities and strict implementation of IPC electronic assembly acceptance standards. Regarding PCBA testing, we have professional engineers to perform 100% batch testing using various test stands, including pathway, noise, amplitude, signal, temperature, humidity, drop or execute customer’s detailed test program. All efforts aim to be a fine PCBA processing manufacturer.
