Regulations Are The Guarantee To Improve PCB Productivity

- Dec 27, 2019-

How does PCB manufacturers improve production efficiency and ensure product quality ? The establishment of equipment maintenance rules and regulations is necessary. Ensuring that the equipment is always in a good state of normal operation is an important means to ensure product quality and production efficiency.


(1) Strengthen the daily maintenance of the machine

Pcb assembly and placement machine is a very complicated high-tech, high-precision machine, which requires working in a constant temperature, humidity and very clean environment. It is necessary to adhere to the daily, weekly, monthly, semi-annual, and annual maintenance instructions strictly in accordance with the requirements of the equipment regulations, and perform routine maintenance.


(2) Requirements for equipment operators

①Operators should receive certain PCB printing expertise and technical training.

② Operate strictly in accordance with the machine's operating procedures. Do not operate the device with a fault. When a fault is found, it should be shut down in time, and

Report to the technical personnel or equipment maintenance personnel, and use it only after the exclusion.

③ The operator is required to concentrate on , be diligent with their eyes, ears and hands

Eye attendance- observe one by one whether there are any abnormal phenomena during the operation of the machine, such as the tape reel does not move, the molding tape is broken, and the mounting is not correct.

Ear attendance- listened for any abnormal sound during the operation of the machine, such as abnormal sounds of placement heads, throwing materials, transmitters, scissors, etc.

Hand attendance- found abnormal phenomena and solve one by one in time. Minor faults can solve mechanical and electrical problems by themselves, and have to be repaired by maintenance personnel.

(3) Develop measures to reduce or avoid errors

When the PCB is assembled, the easiest and most common error is the incorrect mounting components , so the following measures are formulated to prevent it.

① After the feeder is programmed, a professional person must check that the component values in the numbered positions of the material station correspond to those in the programming table.

Is the component value of the feeder number consistent? If not, it must be corrected.

②Belt feeder, when each tray is refilled after placement. Someone must check whether the new tray value is correct.

③ Must be edited once after 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 placed, it must be inspected by a professional person. If problems are found, they should be corrected in a timely manner by modifying procedures.

⑤ During the mounting process, check the mounting position for incorrectness and throwing. Technicians on the Pcb manufacturing assembly line should promptly check for problems and rule them out.

⑥ Set up a pre-weld inspection station (manually or through AOI)

In short, the speed and accuracy of the PCB assembly machine are certain. How to play the role of PCBA processing equipment, human factors are very important. It is necessary to formulate effective rules and regulations and management measures to ensure the normal operation of the machine and ensure the quality and efficiency of placement.
