The SMT production line is mainly composed of solder paste printer, high-speed pick and place machine, multi-function SMT chip mounter, reflow oven and SMT AOI. If two JUKI pick and place machines complete a placement process, the time (hereinafter referred to as placement time) is not equal Time, it will affect the patch rate, the 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 two JUKI SMT placement machines;
2. JUKI PCB pick and place machine itself. We all know that the SMT placement machine itself has a 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, X/Y structure placement For the chip machine, 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 type of components together to reduce the number of nozzle changes when the placement head picks up components and save Placement time.
The SMT production line consists of many equipment. If any equipment is processing, if the speed is slow, it will delay the placement time and affect the actual processing process. How to improve is not only guided by theory, but also on-site operator's rich experience.
The most important thing for Smt placement machine operating technicians is good materials, who are skilled in handling simple abnormal alarms, can switch programs, and debug production to maximize the efficiency of the smt placement machine production line.
To manage the operation technicians of the JUKI SMT pick & place machine the technicians must be thoroughly trained. The smt placement machine is a high-precision SMT equipment. Before using it, you must receive system training from the placement machine manufacturer before you can operate the placement machine. SMT placement machine operation technical personnel refer to technical workers who undertake the specific operations of smt equipment or processes in production positions and have a certain understanding of SMT equipment, placement materials, and chip materials. The corresponding post groups include comprehensive management personnel (such as material managers), equipment or process operators, etc.
