Конфигурация производственных линий селективной пайки волной может быть классифицирована по различным категориям. В этой статье мы рассмотрим конфигурацию производственных линий селективной пайки волной с использованием концепции модулей. Помимо стандартизированной пайки волной, существует множество различных типов флюсования, предварительного нагрева и методов пайки для других процессов машинной пайки. Давайте вкратце представим...
Fluxing Techniques: There are two main fluxing techniques: spray fluxing and drop fluxing.
- Spray Fluxing: This method is generally more efficient and has been used in the assembly industry for many years. It can be used to apply a large amount of flux quickly. However, the drawback is that it leaves more flux residue, requiring more maintenance of the equipment and potentially more frequent replacement of worn-out parts.
- Drop Fluxing: Drop fluxing is more precise and can better fill holes. It leaves minimal flux residue, and the equipment usually requires less maintenance. However, the cost of this equipment is very high, and its operation speed is particularly slow, with more complex programming.
Preheating Techniques: The purpose of preheating is to minimize thermal shock before soldering. Preheating systems can be integrated with selective soldering equipment or provided as optional modules for selective soldering machines. They can be divided into:
- Fast Infrared Heating Technology
- Local Infrared Heating Technology
- Local Quartz Crystal Resonance Heating Technology
Soldering Processes: Common soldering processes include three main types:
- Solder Wave Soldering: Similar to wave soldering, it directly sprays solder waves. Its advantages are similar to those of wave soldering. It has a minimum soldering diameter of 4 millimeters, low maintenance requirements, and relatively low cost.
- Wettable Nozzle Soldering: It can solder from all directions (360°) or along the X or Y axis. It can easily control the height of the solder wave, and its minimum soldering diameter is 3 millimeters. It has higher cost and requires regular maintenance compared to solder wave soldering.
- Hybrid (Micro Wave Nozzle and Drop Fluxing Combination): This process combines aspects of micro wave nozzle and drop fluxing techniques.
The specific configuration of a селективная пайка волной production line depends on the specific production process and environmental standards.
