PCB Technical - Documents provided at the time of PCBSMT patch quotation

Talk about the two documents that customers must provide when asking for PCBSMT patch quotation. Regarding this issue, let PCBSMT patch factory give you a detailed explanation, let's take a look!

Some customers are not clear about what kind of quotation information to provide when asking prices. Most of the information provided by customers is not the information needed for SMT processing, such as the plans and pictures provided by the customers. These non-professional things, in In addition to the incomplete information when smt quotes, it also takes a lot of time. If the customer is in a hurry to quote, time is wasted in the process of asking for quote information. Therefore, the customer needs to provide two materials when inquiring about the price.

The information that needs to be provided for PCBSMT patch processing are: gerber (the production materials of the PCB board) and bom (the bill of materials or the list of components). English name: Bill Of Material. It should be noted that the list of components should be as clear and detailed as possible. The details go to the brand, specification, size, quantity, type and so on of the components.

PCB (gerber) materials are different in the eyes of electronic engineers and electronic designers.

Electronic engineers understand that gerber is the kind of material and process requirements for PCB circuit boards for production. The electronic designer is based on the circuit distribution on the PCB circuit board, the layout requirements and whether the circuit is powered on, but the combination of the two is still the same information required for SMT quotation.

Standard Gerber is represented by RS-274, which is a two-dimensional vector image description format and a standard format for image description in the circuit board industry. The PCB (Gerber) data is sent by the customer to the PCB factory for production. After the engineer imports the CAM software, the electronic engineer provides each PCB process data for each customer who needs PCB board manufacturing. Gerber data can also be used to provide image data for specific equipment, such as automated optical inspection equipment, and can also be used to describe drilling information.

BOM is a product structure data file that can be recognized by a computer. It is also the leading document of ERP. It is also a document for the customer's need for a specific component or the final document for SMT manufacturers to purchase quotations. BOM is the accounting cost of the financial department and an important basis for the production department. Therefore, the impact of the bom list has the greatest impact on the entire manufacturer and customers. The requirements for bom and accuracy are very high, so the low and high prices are based on the bom provided by the customer. The list affects whether the device needs to be imported or domestic, and the price is different. The correct SMT chip processing quotation process is to provide your bom list.

So, in order to make a quick quotation for PCBSMT chip processing in 2 hours, the customer must prepare the gerber production materials and the bom material list when inquiring. You can save your time and know the price quickly.
