The efficiency of SMT patch processing has many aspects. For example, if the overall production volume is constant and the number of SMT patch production lines is large, the production speed can also be increased. However, the operating cost is also increasing. Nowadays, the fierce competition in the electronics industry is unimaginable. In the case of the existing placement production line, it is essential to increase the placement rate and win customer satisfaction. The editor of the Dongguan placement processing plant will briefly introduce the factors and improvement measures of the SMT placement rate:
The SMT production line is mainly composed of screen printing machine, high-speed placement machine, multi-function placement machine, reflow soldering machine and AOI automatic detector. If two placement machines complete a placement process, the time (hereinafter referred to as placement time) is not equal When the time, it will affect the patch rate, specific methods:
1. Balanced load distribution. Reasonably allocate the number of two SMT components to achieve a balanced load distribution to achieve the same placement time for the two SMT placement machines;
2. SMT placement machine itself. We all know that the SMT placement machine itself has a maximum placement speed value, but it is generally not easy to achieve this value. This has a certain relationship with the structure of the SMT placement machine, for example, the X/Y structure For placement machines, the measures taken is to make the placement head pick up components at the same time as much as possible. On the other hand, when arranging the placement program, arrange the same types of components together to reduce the number of nozzle changes when the placement head picks up components. Save mounting time.
The SMT production line is composed of many equipments. When any equipment is processed, if the speed is slow, it will delay the placement time and affect the entire processing process. How to improve is not only guided by theory, but also by the rich experience of on-site operators.
