SMT factory overall arrangement and location requirements

1. Placement area of fire extinguisher

Fire extinguishers should be placed beside the column and around the SMT workshop, and placed in accordance with the requirements of fire protection regulations.

2. The placement area of the material storage cart

The materials storage cart is used for the SMT production line and the replacement of materials when the model is switched. In order to facilitate production and improve the efficiency of material replacement, it is best to place the material storage cart near the placement machine. Moreover, since the material can be replaced on both the front and rear sides of the placement machine, at least one material storage cart should be placed on both sides of the placement machine.

3. Placement area of the preparation table

The material preparation table is mainly used for the preparation of materials in the production process and the material preparation work before the machine switching. Therefore, the material preparation table should be placed near the placement machine; Also, it is best to put it together with the materials storage cart , so that it can be placed to the materials storage cart directly after the material is prepared.

4. Small table placement area for printing station

The small printing station table is used to place the auxiliary tools of the printing machine in production, such as wiping paper, solder paste, alcohol, etc. Considering easy access and use, it should be placed near the printing machine , and improve production efficiency.

5. Solder paste placement area

The solder paste placement area includes a refrigerator for storing solder paste, a solder paste mixer, a solder paste reheating cabinet, etc., which can be placed next to the column or in a fixed area around the workshop according to the requirements of the workshop; In a word, solder paste placement area should be convenient for production line to take solder paste.

6. Visual inspection area and maintenance area behind the furnace

In order to facilitate the visual inspection and maintenance of the semi-finished boards after the furnace, a small table is generally placed behind the furnace, which is specially used for the visual inspection and maintenance after the furnace, and the produced boards are promptly carried out to the next operations.

7. Stencil placement area

The stencil placement area includes a stencil storage cabinet, a stencil cleaning machine, a stencil inspection tool, etc., which are used for stencil storage, cleaning and stencil tension checking, but it should be convenient to take stencils in the production line.

8. Garbage placement area

The garbage in the production mainly comes from two parts, one is the dust-free paper used in the printing operation, and the other is the waste tray and waste belt caused by the replacement of materials. The garbage generated in these two parts should be placed separately for special recycling, especially the garbage used by the printing press. Therefore, the garbage area can be placed next to the printing machine and the placement machine, or a garbage placement area can be set up next to the column, and placed separately.

9. Checking boards placement area

SMT checking boards includes production checking and quality management checking, etc., which can be centrally placed next to the entrance and exit of the workshop or set up production checking boards area at the end of each production line to centrally place quality and others, so that producers and managers can check and understand the current SMT production status and quality status timely.

10. Boards placement area

The boards produced include finished boards and semi-finished boards. These two boards placement area should be separated and strictly distinguished to avoid confusion.

11. SMT spare tools placement area

SMT spare tools, including nozzles, motors, belts, cylinders, which should be placed in special areas to facilitate access during production, especially valuable spare tools; Meanwhile, safety settings should be taken.

12. Temperature and humidity location area

In order to better understand the temperature and humidity of the SMT workshop, according to the size of the workshop area, set up several temperature and humidity measurement areas, generally placed on the column or wall next to the production line.

13. SMT workshop office area

Let the engineering and technical personnel and management personnel work on-site in the SMT workshop, which can solve the technical and management problems encountered in production in time and ensure the smooth production of the SMT production line.

14. Area for anti-static measures

The personnel entering the SMT workshop must have an area where anti-static measures are taken. The area can be delineated at the door of the workshop, including the replacement of electrostatic clothing, shoes, hats, and each employee's locker. In addition, an area dedicated to testing the electrostatic ring should be set up at the entrance of the SMT workshop so that each employee can do the electrostatic ring test and record the test results before starting to work.
