Those rules and regulations in PCB manufacturing

They all say, "There is no rule, no square." Any product manufacturing should abide by the rules, and PCB manufacturing is no exception. Only by establishing the rules and regulations of each link in PCB manufacturing, and strictly implementing them, and at the same time effectively supervising the implementation process, and immediately rectifying problems when problems are found, can the production efficiency be effectively improved and product quality guaranteed. Below, let us take a look at the rules and regulations in PCB manufacturing:

1. Daily maintenance of SMT placement machine

The SMT placement machine is a high-tech, high-precision machine with high requirements for constant temperature, humidity, and environmental cleanliness. During maintenance, we must strictly follow the regulations, adhere to daily, weekly, monthly, semi-annual, and yearly maintenance instructions, and do a good job of daily maintenance.

2. Requirements for equipment operators

1. Operators need to receive certain SMT professional knowledge and technical training.

2. Operate strictly in accordance with the machine operating regulations. It is not allowed to operate machinery and equipment with faults in order to eliminate hidden production hazards. Once the fault is found, it should be shut down in time, and reported to the technician or maintenance personnel, until it is completely repaired and the fault is eliminated before it can be used.

3. Operators should concentrate their energy during the operation, and achieve "three diligence":

Be diligent to observe whether there are abnormal phenomena in the operation of the machine, such as improper placement of components, etc.

Ear Qinyi listen carefully for abnormal sounds during the operation of the machine, such as the abnormal sounds of the placement head, throwing, and transmitter.

Shouqin found the problems one by one and solved them in time. Solve minor problems by yourself, and ask maintenance personnel for major problems.

3. Develop measures to reduce or avoid errors

The most error-prone SMT patch is the wrong component and incorrect placement. The following preventive measures are formulated:

1. After the feeder is programmed, someone must check whether the component value at each numbered position of the material station is consistent with the component value of the corresponding feeder number in the programming table.

2. Tape feeder, when each tray material is refilled after placement. There must be someone to check whether the value of the new material pan is correct.

3. It must be edited once after patch programming. Check whether the component number, rotation angle and placement position of each placement step are correct.

4. After the first piece of each batch of products is installed, there must be a special person to inspect, and if any problems are found, they should be corrected in time through methods such as modifying procedures.

5. During the placement process, always check the placement of the correct position, throwing materials, etc. The technicians on the SMT processing line should check the problems in time and eliminate them.

In short, PCB manufacturing is a complex and long project, and there are many rules and regulations that need to be followed. The above is only an introduction to the rules and regulations that the production equipment is in use and the production personnel should abide by in the production. To ensure the normal operation of machinery and equipment, to ensure the improvement of work efficiency and yield, to ensure the high quality of products and the return rate of customers, those rules and regulations in PCB manufacturing must be strictly implemented. After all, no matter how effective the system is, after all, it must be implemented in people, and the human factor is very important. In our production, it is not enough if the personnel are in place. We must continue to improve the quality of the operators. This is a compulsory course for any PCB company.
