Before SMT Assembly Processing Quotation, Have You Prepared These Materials?

Publish time:2024-07-12 08:42:03   Views:

Today, Charmhigh Electromechanical will discuss with you that in SMT assembly processing, accurate and timely quotation is an essential link to ensure the smooth progress of the project. To obtain an accurate quotation, the materials provided to the SMT assembly processing factory must be detailed and accurate. Here are the key materials required for SMT assembly processing quotation.

Before SMT Assembly Processing Quotation, Have You Prepared These Materials?!!3446553168.jpg

I. Gerber Files


Gerber files are indispensable authoritative documents in SMT assembly processing. They contain all the design information of the PCB board, such as the Pad layer (solder pad layer), solder mask layer, silkscreen layer, and stencil layer. These materials are crucial for the quotation and processing fee evaluation of the PCB board, as they directly affect the production cost and process complexity.


II. BOM List (Bill of Materials)


The BOM list details all the components used on the PCBA board and their related information, such as brand, model, and specifications. Since the prices of components vary greatly among different brands, models, and specifications, the BOM list is essential for accurately calculating the material cost. At the same time, the BOM list is also an important basis for evaluating the processing fee, as the calculation of the processing fee is usually based on the number of components.


III. Coordinate Files


Coordinate files are important documents used to locate component positions in the assembly process. They contain precise coordinate information for each component on the PCB board, ensuring that components can be accurately placed in designated positions during the assembly process. Therefore, providing coordinate files is crucial for ensuring the quality and efficiency of the processing.


IV. Process Instruction Documents


Process instruction documents are explanations and guidance provided by the designer for specific process requirements during the processing. They may include placement requirements for special components, handling requirements for special materials, etc. Providing process instruction documents helps SMT assembly processing factories better understand the designer's needs and ensure that the processing process meets the design requirements.


V. Test Specifications


The test specifications describe in detail the various test items and requirements that need to be performed on the PCBA board after processing. These test items may include electrical performance tests, functional tests, etc. Providing test specifications helps SMT assembly processing factories understand the test requirements and standards, ensuring that the processed PCBA board can meet the design requirements and usage requirements.
