Main content of lean factory design
The traditional way of plant layout begins with equipment and tooling, and finally considers the flow of processes. Unlike traditional factory layouts, lean factory design layout begins with the customer and then designs the process flow around the workforce.
Lean factory design should comprehensively apply the knowledge of lean production ideas, system engineering, enterprise management, etc., and use parallel technology, information technology and other means to determine the factory design plan that meets the requirements of lean production concept. The main design contents are as follows:
(1) Production line layout based on lean thinking
The design of the best production line must be independent of the current legacy workflow and should reduce or eliminate large amounts of moving time for products and materials. According to the assembly requirements, placing the part loading process on the assembly point where the material of the production line is consumed will reduce the movement and waiting time.
(2) Lean logistics system design
According to the lean production point of view, logistics is not a value-added link. Therefore, the goal of lean logistics system design is to minimize the logistics and strive to minimize the waste in the logistics process while meeting the production requirements. To break the limitations of the profession, try to set up and no intermediate inventory area, and completely follow the process flow layout. All ideas that minimize the amount of movement and optimize the flow of the product should be tested. Ultimately, a practical and appropriate approach should be taken to finalize the production line in order to maximize the benefits of the production process. .
(3) Lean selection and arrangement of equipment
It is necessary to fully consider the relationship between the various production links, and on the basis of realizing the capacity requirements, try to achieve a balanced production capacity and reflect the idea of lean flow. At the same time, the choice of equipment is not based on the most advanced standards, but the small size, low investment, flexibility and other indicators are put in the first place, in order to meet the needs of flexible production in the future.
(4) Lean staffing
Traditional factories use the “scheduled system” staffing, but this method increases the cost of the enterprise and reduces the response speed of the enterprise under the multi-variety and small-batch production methods. Lean factory design, it is recommended to use the least staff to achieve the same production needs, through the training of employees, so that it has a variety of skills, so that with the change in production, flexible arrangements for operators.
(5) Lean selection of auxiliary equipment
Although the fixtures and tools required for production assistance are not resource equipment, they must be considered for lean production. It must be designed to accommodate the movement of the required materials, such as the passage of the automatic loading and unloading trucks and large material containers. It is necessary to design the station to be more compact, but at the same time, the operator should be considered to be as ergonomic as possible.
In addition, the design of the lean factory should also include the planning of the public facilities of the factory, the design of the information system, etc., and should be carried out according to the specific needs of the factory and the actual situation of the enterprise.
The goal of lean plant design is to minimize waste and overload in the work process while enhancing visual communication on site.
After the PCB is manufactured, it has a shelf life. If the shelf life is exceeded, the PCB needs to be baked. Otherwise, it is easy to cause the PCB to explode when the PCB is produced on the SMT.
Baking can eliminate the internal stress of the PCB, which is to stabilize the size of the PCB. The baked board has a relatively large improvement in warpage.
Advantages of baking: After baking, the moisture in the pad can be dried, the welding effect is enhanced, and the welding and repair rate are reduced.
Disadvantages of baking: The color of the PCB board may change, affecting the appearance.
The main purpose of PCB baking is to remove moisture and remove moisture from the PCB.
First, the specification of PCB management
1, PCB unpacking and storage
(1) PCB board seal can be directly used online within 2 months of unopened manufacturing date
(2) PCB board manufacturing date is within 2 months, the date of unpacking must be marked after unpacking
(3) PCB board manufacturing date is within 2 months, after opening, it must be used within 5 days.
2, PCB baking
(1) If the PCB is sealed and unsealed for more than 5 days within 2 months of the date of manufacture, please bake at 120 ± 5 °C for 1 hour.
(2) If the PCB is more than 2 months from the date of manufacture, please bake at 120 ± 5 °C for 1 hour before going online.
(3) If the PCB is more than 2 to 6 months from the date of manufacture, please bake at 120 ± 5 °C for 2 hours before going online.
(4) If the PCB is more than 6 months to 1 year before the date of manufacture, please bake at 120 ± 5 °C for 4 hours before going online.
(5) The baked PCB must be used within 5 days (input to IR REFLOW). After the bit is used, it needs to be baked for another hour before it can be used.
(6) If the PCB exceeds the manufacturing date of 1 year, please bake at 120 ± 5 °C for 4 hours before going online, and then send it to the PCB factory for re-spraying before it can be used.
3, PCB baking method
(1) Large PCB (16 PORT and above including 16 PORT), placed in a flat format, with a maximum of 30 sheets in a stack, and the oven is opened within 10 minutes after baking. The PCB is placed in a flat and natural cooling (requires pressure to prevent the bay fixture)
(2) Small and medium-sized PCB (8PORT below 8PORT) is placed flat, the maximum number of stacks is 40 pieces, the number of uprights is not limited, the oven is opened within 10 minutes after baking, and the PCB is placed flat and naturally cooled (requires pressure protection) Banwan fixtures)
Second, the preservation and baking of PCBs in different regions
The specific storage time and baking temperature of the PCB are not only related to the production capacity and manufacturing process of the PCB manufacturer, but also have a great relationship with the region.
The PCB made by the OSP process and the pure immersion gold process generally has a shelf life of 6 months after packaging, and is generally not recommended for the OSP process.
The storage and baking time of PCB has a great relationship with the area. The humidity in the south is generally heavier. Especially in Guangdong and Guangxi, there will be “returning to the south” weather every year in March and April. It is very wet at this time. The PCB must be used up within 24 hours of exposure to air, otherwise it will be easily oxidized. After normal opening, it is best to use up to 8 hours. For some PCBs that need to be baked, the baking time is longer. In the northern regions, the weather is generally dry, the PCB storage time will be longer, and the baking time can be shorter. The baking temperature is generally 120 ± 5 ° C baking, baking time is determined according to the specific circumstances.

Automated optical inspection machine (AOI) is a new type of testing technology. It has
developed very rapidly in recent years. The structure of AOI consists of four parts: workbench, CCD camera system, electromechanical control and system software. When testing, firstly, the circuit board to be tested is placed on the workbench of the AOI machine, and the detection
procedure of the product to be detected is called out through positioning. The X/Y workbench
will send the circuit board under the lens according to the command of the setting program. With the help of the special light source, the lens will capture the image required by the AOI system and analyze it, then the processor will move the lens toward the lens. The next position is
collected for the next image and then analyzed, and the image is subjected to continuous
analysis and processing to obtain a higher detection speed. The process of AOI image
processing essentially digitizes the extracted image, and then compares it with the pre-stored “standard”. After analysis and judgment, it finds the defect to make a position prompt, and at the same time generates image text, and the operator further confirms or sends the repair station. Overhaul

How SMT workshop planning!
And only after the plant began production found that some areas have not planned beforehand, need to be adjusted, resulting in a waste of human and financial resources and valuable production time.
Therefore, it is important to check in advance SMT factory layout, especially for new SMT factory business, because there is no experience in SMT plant layout, the need to pay attention to the elements is not very clear, if we find a problem in the layout after production point, will cause some unnecessary losses.
So, when doing layout SMT plant, what to pay attention to what matters in advance to do to prepare? Here actual cases where we work to and we explore this problem.
planning SMT line configure
the client recent planning new on two identical SMT production line, specific device configuration (see FIG. 1) and the size of the apparatus is as follows: According to Figure 1 can be seen, the maximum width of the production line equipment is 1.71 m, the length of all devices sum is 13.6 meters, will add future planning a production line (line bulk on equipment configuration).
Workshop length 36 m, width of 12 m, an area of 432 m2, on the ground floor of the factory. Currently common ground for the shop floor, and no established anti-static system, can not meet the requirements of SMT antistatic workshop, but two conductive ground terminals, can establish subsequent workshops antistatic SMT system. Further, there is no air conditioning workshop and humidifiers, can not meet the requirements of SMT workshop temperature and humidity control. There workshop ventilation system, back to meet the requirements of the reflow furnace equipment. Workshop sufficient power to meet the electricity needs of all equipment in the workshop. There are two entrances whole plant, as are required to meet the equipment, raw materials and semi-finished channel. Special materials warehouse in another workshop, the need for planning. Good lighting conditions in the workshop, to meet the brightness of the SMT shop lighting requirements all stations. Whole plant layout situation shown in Figure 2.
1, the current new move into production lines and related aids, regional positioning;
2, the whole plant to meet future erection and production requirements three production lines, without planning zone realignment;
3, each production line starting position as consistent as possible, so that the whole plant orderly arranged in three lines.
analysisthe customer’s request, we first analyzed how the production line positioning; and before locating the production line, we consider the following points:
1, SMT equipment should avoid column and they maintain a certain distance, the distance is equipment installed at least after a good feed material by a vehicle;
2, SMT crossing equipment required for frame division pitch, and the crossing equipment to extend outwardly after the device installed above the material 50 cm;
3, optimal spacing of the two lines spaced more than 1.2 meters between the outer frame;
4, check the wire tail is generally a repair plan area, quality control personnel can perform sampling line tail region.
Based on the above considerations, the length of each line should be at least 13.6 meters (without regard to the maintenance area and the tail, the case where the sampling area and the thread area kanban), the width should be 2.7 meters (SMT feeding both surfaces), specifically as shown in Figure 3.
Therefore, the production line is positioned in substantially considering plant shown in FIG. 4.
Some details of the requirements of SMT plant layout
after determining the approximate location of the production line, when the need to consider some details of SMT production line requirements, and then to determine the exact location and the location of other auxiliary equipment SMT line.
First, we analyzed the SMT line position and aids required for each area requirements: 1, fire extinguisher drop zone;
fire extinguishers to be placed around the side of the post and SMT plant, placed according to the requirements of fire regulations.
2, the car rack placement region; car rack replacement for SMT production line models and switching material, in order to facilitate production and to improve the efficiency of replacement materials, preferably the vehicle is placed near the rack placement machine.
3, stock units rest area;
stock table mainly used in the production process and dryer materials stock preparation before switching, therefore, to be placed near the preparation station placement machine, and the best car rack together, Preparation facilitates directly on the car frame after a good feed material.
4, the shelf rest area printing station;
printing station for positioning the shelf aids in the production of printing presses, such as wipes, paste, alcohol, etc., to be placed in the vicinity of the printing press to facilitate removal use, improve Productivity.
5, placing solder paste regions;
region comprising placing solder paste storage refrigerator, solder paste mixer, paste warmed cabinets, can be placed next to the plant as required or uprights placed around a fixed area of the plant, However, to facilitate the operator to take place.
6, visual inspection after the furnace area, maintenance area;
in order to facilitate visual inspection after reflow and rework semifinished product, a shelf generally placed in the furnace, designed for the visual inspection of the furnace and rework.
7, screen placement area;
drop zone comprises a mesh screen plate was placed cabinet, stencil cleaning machine, inspection tools, screen, stencil for storing, cleaning and inspection screen tension, etc., while in the region as much as possible to facilitate the production screen to take place.
8, garbage drop zone;
Production waste mainly from two parts, wipes and the like used in one printing operation, the second is to replace the waste tray and waste material produced with the like. Garbage two parts is generated to be placed separately, specialized recycling, in particular waste presses used. Thus, waste area may be placed next to the press machine or patch, or set beside the column region refuse placed separately placed.
9, kanban placement region;
kanban including the SMT billboards and other signage quality management, may be centrally located on the entrance into the shop, and also set up the production line Kanban state in which each head of the line, in order to view the producers and managers, promptly understand the current state of production status and quality SMT workshop and so on.
10, product placement area;
include products produced finished products in two parts, to separate the two partial regions divided out, strictly distinguished, in order to avoid confusion.
11, SMT placement of spare areas;
12, location area temperature and humidity;
temperature and humidity conditions in order to better understand the SMT plant, depending on the size of the workshop area, several appropriately set the temperature and humidity measurement area, generally placed on the production line next to the column or wall.
13, SMT workshop office area;
let engineers and technicians and management personnel in office SMT shop floor, which can solve the problem on technology and management encountered in the production, to ensure the smooth operation of the SMT production lines.
14, anti-static protection area;
entry into SMT workshop area must have good anti-static measures. You may delineate the area in front of the plant, including the replacement of static clothing, shoes, hats and so on each employee’s locker. Also, the establishment of regional designed to test the static ring in SMT workshop at the entrance, so that each employee to do static loop testing and record test results before going to work. Based on the above analysis, the results of this SMT plant layout is shown in Figure 5.
In addition, SMT workshop also meet other requirements: 1, anti-static processing;
shop floor must be anti-static treatment, a common anti-static conductive flooring and paint and other ordinary places, customers can choose according to the actual situation. In addition, anti-static system must be set up in the workshop, to meet the requirements of the entire anti-static SMT workshop.
2, air-conditioning and a humidifier; SMT workshop to meet the requirements of temperature and humidity control.
3, the material management requirements;
in the warehouse, with particular attention to the way the material is stored, reel packaging methods, the use of hook-type place, wetting elements employed Cabinets for placement shelves to be treated with anti-static manner.
4, patch equipment gas and electrical circuitry;
preferably introduced directly from the production line at the down side of the roof, is arranged below the gas passage in the device and circuit wrapped with wire groove.
5, the ventilation system requirements;
needs to be installed to meet the requirements of the three power lines of the blower, and the third exhaust port reserved line.
1, according to the size of production line and the size of the entire plant SMT, completed the reasonable position of the production line; and
2, for aids, regions, etc. SMT production lines need to make the corresponding position location; 3, according to the SMT the characteristics of the plant, some of the necessary factors to consider in planning, in particular, anti-static; 4, in accordance with the requirements of the current situation and future development of the factory has been take into consideration, unified planning.
For SMT plant layout, but also requires a combination of size and product requirements and other plants to consider a number of factors, but to stimulate here.
