Although the smt patch processing is now automated, it does not mean that no manual work is required. In fact, manual operation is inevitable in the process of smt patch processing and maintenance.
31% of the quality problems of smt patch processing in the automotive industry are caused by improper process control. It can be seen that the quality control of smt patch processing in the automotive industry is very useful and an important way to improve product quality. The engineers of PCBA Co., Ltd. analyzed the following points to share with you:
smt patch processing
1. SMT chip processing quality control
The quality control of smt processing in the automotive industry is an important step to ensure product quality and factory production efficiency. Taking the reflow soldering process as an example, although the furnace temperature control system and temperature sensor in the reflow soldering furnace can be used to control the temperature in the furnace, the actual temperature of the solder joints on the PCB is not necessarily equal to the preset temperature of the reflow soldering. Although the reflow soldering machine works normally, the temperature control is also within the temperature control accuracy range of the equipment. However, due to uncontrollable factors such as the quality of the PCB, the assembly density, and the number of PCBs entering the furnace, the furnace temperature curve will fluctuate accordingly. Therefore, the temperature of the reflow soldering machine must be continuously monitored to ensure the quality control.
2. Technical requirements for quality control of SMT patch processing
Quality control requires technicians to have good measurement knowledge, statistical knowledge, causal analysis capabilities, and an in-depth understanding of equipment performance.
There are variables on the production line. The aging of equipment, the adjustment of personnel, and the quality of materials will all influence and restrain each other, causing fluctuations in the quality of SMT products in the automotive industry. Therefore, it is very difficult to adopt effective and continuous quality monitoring methods without affecting production and increasing production costs.
3. The method of SMT patch processing quality control
At present, most of the smt chip processing manufacturers in the automotive industry use advanced testing equipment to monitor the quality of the production process. During the reflow soldering process, AOI inspection equipment is generally used for quality control.
Due to the high cost of automatic parameter adjustment and feedback in the quality control process, manual settings are required. In this case, it is even more necessary for smt patch companies in the automotive industry to formulate some practical and effective specifications and systems, strictly implement the established specifications, and achieve process stability through manual monitoring. In the formulation of quality control specifications for the price of automotive electronic smt patches, the response ability of the operators and the precise control of the equipment are very important.
