SMT operation instructions

Working Introduction (WI) The composition of the working introduction varies according to the structure of the product and the processing procedure. Generally, SMT WI contains the following contents:

Content introduction:

① is the basic identification and elements of the document. Including: company name, document name, number, edition, page number, production time, release time and other identification and process, process name, working hours, product model, name and other basic elements. It includes the file management and the description of the operation object and the operation time requirements. Such as document name, edition and model and working time.

② is the graphic part, is to let employees have a more intuitive and clear understanding of the content of the job, to achieve the purpose of easy to understand.③ is the specific operation method and necessary steps on the job. It is a detailed operation content made in order to meet the quality requirements and production efficiency requirements and avoid confusion and wrong operation steps. To ensure product quality and production efficiency.

④ Precautions: The content of the operation is to put forward some prevention of poor operation or production safety. Prevent and reduce defective products; Ensure personal safety, equipment safety role.

⑤ Material table is the specific requirements of material application, package name, specification, quantity, etc., is to let employees clearly use the requirements of materials. It can avoid the problem of material error on the operation.

⑥ Equipment and tool list. It is an essential tool or equipment that is required to ensure quality or efficiency in a production operation.

⑦ Auxiliary material table. It is a number of auxiliary materials required for the normal operation of equipment in production.

Two > The role of work instructions

Through the understanding of the components of the above work instructions, it can be understood that the role of the work instructions are mainly:

1, the role of ensuring product quality in production. Because each person operates according to the corresponding operation instructions content and steps, it is equivalent to different operators according to the same mode of operation, the result is that the product is printed like a mold, the product quality is unified, and the standardization effect is produced. So the quality of the product is guaranteed.

2, improve production efficiency. Under normal circumstances, the operation instruction is written after a comprehensive analysis of the product structure, material properties, processing methods, processing steps, processing points, processing economy, etc. It integrates the above processing factors, which is easy to cause a variety of waste in production: Such as waste of working time caused by redundant actions, defective products caused by wrong working methods, waste of materials and processing time, machine damage caused by non-standard operation of tools and equipment, personal injury and other economic losses, IE will generally put forward some preventive methods and measures in the work instructions; Therefore, correct operation can reduce or avoid the time and economic losses that are not effective for the operation itself, but will cause serious consequences. IE will generally optimize the content of the operation, so according to the scheduled operation method can eliminate the waste of working hours and defective products, and improve output, which will achieve the purpose of improving production efficiency.

4. Play the role of guiding correct operation. For a new product or employee, it's important to have a clear written work guide. It can avoid blind work and reduce groping time; Because of the work instructions and methods to follow, you can quickly and correctly complete the corresponding work content.

5. Improve the image of the company. The operation instruction is a main window for customers to understand the level of our company's manufacturing process, through which they can know the company's manufacturing process level, and can also predict how the quality of the product can be achieved. A good work guide will allow customers to have an intuitive understanding of the company's manufacturing process, and have a good impression, but also more trust and rest assured of our manufacturing process potential.
