What does an SMT engineer do? What kind of knowledge do they value?

SMT engineers are familiar with and responsible for surface mounting.

Technical (SMT) engineer. They are responsible for ensuring the design, debugging and production of SMT process in the manufacturing process of electronic products.

The main responsibilities of SMT engineers include:

1. design review and support: participate in product design review, cooperate with design engineers to determine the best SMT process, and provide relevant suggestions and technical support.

2. Process development and optimization: responsible for developing and optimizing SMT process flow, including installation and welding process, steel mesh design, component installation parameters, etc. To ensure high quality assembly.

3. Equipment selection and operation: select appropriate SMT equipment and debug it, and be familiar with and operate various SMT equipment, such as mounter, reflow oven, printing machine, etc.

4. Troubleshooting and quality control: use test equipment and tools to troubleshoot, control and ensure the quality of SMT components to ensure the yield of products.

For SMT engineers, the following knowledge is more important:

1.SMT process knowledge: Understand and be familiar with the principles, processes and standards of SMT process, including the selection and placement of components, the design and manufacture of steel mesh, welding process parameters, etc.

2. Equipment operation and maintenance: familiar with the operation, debugging, troubleshooting and maintenance of various SMT equipment, and able to flexibly meet the needs of different equipment.

3.PCB design and layout: understand the basic knowledge of PCB design, including wiring rules, component spacing, impedance control, etc. In order to communicate effectively with design engineers.

4. Quality management and standards: Be familiar with the quality management system and related standards, such as ISO 900 1 and IPC standards, to ensure that the products meet the quality requirements.

To sum up, SMT engineers need to have in-depth SMT process knowledge, master equipment operation and maintenance skills, and have good PCB design and quality control capabilities.
