SMT prevents incorrect data and placement of machine boards
In the production process, the SMT production line will run out of tape or pallet data in a certain period of time. In this case, the production line operator needs to replace the material pallet in a timely manner If the operator of the production line changes according to the standard process, it is usually very incorrect information, whICh rarely happens. However, in some aspects, because people are affected by the surrounding environment and human factors, incorrect information still appears on the SMT production line. They are negligent in data matching, and people's emotions are increasingly affected When it comes to work quality, there are wrong data
In retrOSPect, many large factories are promoting SMArt factories or industry 40, integrating hardware and software to realize automatic operation of machinery and build unmanned factories. From the perspective of technology and human resources, this is the future trend of EMS intelligent manufacturing. In this regard, the deployment of smart factories by large electronic processing enterprises should be put on the agenda as soon as possible.
On the prEMIse that we do not have unmanned factory technology, how can we minimize the occurrence of erroneous data caused by human factors? The following editor will explain to you
1. The mounter is equipped with error proofing system. When loading, reloading and receiving data, use the scanner to scan the station number on the machine, and then scan the barcode label on the data. The system automatically checks whether the loading is correct. If there is any error, the system will automatically alarm and lock the line body. After IPQC confirms the inspection reason, enter the password to cancel the alarm. If the line operator receives information privately, it will send an alarm and stop the line.
2. When the line operator installs the material tray on the feeder, confirm the material again. After installation, you can use the line length or QC to match the data.
3. After the scanning code of the scanning gun is checked, the production line operator checks, and the line length or QC checks again, confirm that the data is correct and start production. Generally, after three checks, there is almost no error data.
4. After the first plate is produced on the SMT production line, the first article inspection will be carried out. After confirmation, start batch production. If refueling and receiving are required later, please perform the first step again.
In the above steps, the SMT chip factory operates in strict accordance with the regulations, which can basically prevent the occurrence of erroneous data
Precautions for paster
The main function of the SMT machine is to install electronIC components on PCB pads. Today, many SMT plants have implemented automated smt production lines, but there are still a few small SMT plants that have semi-automatic smt production lines. In this case, it is necessary to manually put printed PCB boards into the conveyor belt of the connection table and flow them into the SMT machine for mounting. Then, what problems should be paid attention to when placing the SMT machine on the circuit board.
The placement machine is located behind the solder paste printing machine and the SPI inspection machine. Some factories may not even have spi. They directly use the semi-automatic printing machine, and then manually put the cardboard into the conveyor belt, which flows into the placement machine for placement.
1. When the mounter is on the board, the circuit board should be parallel to the conveyor belt track and pushed forward slightly;
2. Make sure the PCB is placed on the belt of the conveyor belt. Do not place it so that the circuit board is blocked;
At present, only a few resettlement plants do not have automated smt production lines, and most of them have adopted automated production lines
