SMT chip processing is a PCB circuit board welding processing factory. The main production equipment includes printing machines, dispensers, smt placement machines, etc., semi-automatic and fully automatic; SMT chip processing should pay attention to things that should be applied during processing When it comes to solder paste, the placement machine equipment must be checked regularly, and I will introduce it to you next.
1. Introduction to SMT chip processing
1. SMT processing is the processing production line of PCB circuit board motherboards. I believe many friends do not necessarily know what smt processing is. In fact, smt processing is what we know well: PCB circuit board welding processing factory.
2. The main production line equipment for smt chip processing includes printers, dispensers, smt mounters, reflow ovens and wave soldering machines. Auxiliary equipment includes AOI testing equipment, repair equipment, cleaning equipment, drying equipment and material storage equipment.
3. The smt chip processing production line can be divided into automatic production line and semi-automatic production line according to the degree of automation. According to the scale of the production line, it can be divided into large, medium and small smt chip processing production lines.
4. The semi-automatic smt patch processing production line means that the main smt patch processing production equipment is not connected or not fully connected. The smt printing machine is semi-automatic and requires manual printing or manual loading and unloading of printed boards.
Two, SMT patch processing matters needing attention
1. When performing smt patch processing, everyone knows that solder paste is basically applied. For the newly purchased solder paste, if it is not applied immediately, the SMT factory needs to store it in an environment of 5-10 degrees, so as not to affect the application of the solder paste. In a zero degree environment, it will not work if it is higher than 10 degrees.
2. In the placement process, the placement machine equipment must be checked regularly. If the SMT factory equipment is aging or some components are damaged, in order to ensure that the placement will not be crooked, In the event of high dumping, the equipment needs to be repaired or replaced with new equipment in time. Only in this way can production costs be reduced and production efficiency improved.
3. When performing smt processing, if you want to ensure the quality of PCBA processing and soldering, you need to pay attention to whether the setting of reflow soldering process technical parameters is more reasonable. If there is a problem with the parameter setting, SMT patch soldering The quality cannot be guaranteed. Therefore, under normal circumstances, the furnace temperature needs to be tested twice a day, at least once. Only by continuously improving the temperature curve and setting the temperature curve of the welding product can the quality of the processed product be guaranteed.
