Flux Frequently Asked Questions and Answers

Q: 什么是Flux？ A: Flux是一种用于构建用户界面的应用架构。它专注于数据流的一致性和可预测性，使得应用程序的状态管理更加简单和可维护。 Q: Flux的核心概念是什么？ A: Flux的核心概念包括：单向数据流、数据存储、视图和动作。单向数据流确保了数据的一致性，数据存储用于存储应用程序的状态，视图用于展示数据，动作用于触发状态的改变。 Q: Flux与其他应用架构有什么区别？ A: Flux与其他应用架构的区别在于其单向数据流的特性。传统的MVC架构中，数据的流动是双向的，而Flux中数据的流动是单向的，这样可以更好地控制数据的变化和状态的管理。 Q: Flux的优势是什么？ A: Flux的优势包括：简化的状态管理、可预测的数据流、易于调试和测试、模块化和可扩展性。 Q: Flux的工作原理是什么？ A: Flux的工作原理可以简单概括为：视图触发动作，动作更新数据存储，数据存储通知视图更新。 Q: Flux的应用场景有哪些？ A: Flux适用于构建复杂的用户界面，特别是需要管理大量状态和数据流的应用程序。它在Web开发中得到广泛应用，如React等前端框架。 Q: Flux的实现有哪些？ A: Flux的实现有很多，其中最著名的是Facebook的Flux框架。此外，还有一些其他的Flux实现，如Redux、MobX等。 Q: 如何学习和使用Flux？ A: 学习和使用Flux可以通过阅读相关文档和教程，参与社区讨论和实践项目等方式。同时，掌握React等前端框架也是使用Flux的前提。
There is not much dirt on the PCB board after welding.
  1. The preheating temperature is not preheated before welding or the preheating temperature is too low (when ending, the time is too short).
  2. The walking speed is too fast (FLUX failed to fully volatilize).
  3. The temperature of the tin furnace is insufficient.
  4. It is caused by the addition of antioxidant or antioxidant oil in the tin liquid.
  5. Too much flux coating.
  6. The foot of the component and the plate hole are disproportionate (the hole is too large) to raise the flux.
  7. During the use of FLUX, no thinner was added for a long time.
Yes, it is big smoke and smelly.
The problem of FLUX itself
  1. If you use ordinary resin, the flue gas is large.
  2. Solvent: 这意味着FLUX使用的溶剂的气味或刺激性气味可能很大。 Translation: Solvent: This means that the smell or pungent smell of the solvent used by FLUX may be strong.
  3. Activator: large smoke and pungent smell.
The exhaust system is not perfect.
Electricity connection, leakage (poor insulation)
The PCB design is unreasonable, the wiring is too close, etc.
The quality of PCB solder block film is not good, and it is easy to conduct electricity.
On fire?
  1. The wave furnace itself does not have a wind knife, resulting in too much flux coating, which drips on the heating tube during preheating.
  2. The angle of the wind knife is not right (so that the flux is unevenly coated on the PCB).
  3. There are too many adhesive strips on the PCB, which ignited the adhesive strips.
  4. The walking speed of the board is too fast (Flux is not completely volatile, and Flux drips) or too slow (the heat temperature of the board surface is too high).
  5. Process problems (the PCB board is not good and the heating pipe is too close to the PCB). Translated: The PCB board is not good and the heating pipe is too close to the PCB.
The solder joint is too bright or not bright?
  1. This problem can be solved by selecting bright or matting FLUX.
  2. The tin used is not good (for example, the tin content is too low, etc.).
The color of Flux.
Some colorless and transparent FLUX is added with a few photosensitive additives. It changes color after exposure to light, but does not affect the welding effect and performance of FLUX.
Split, tin beads?
  1. Crafts
  • Low preheating temperature ( FLUX solvent is not completely volatile);
  • The speed of walking the board has not reached the warm-up effect.
  • The chain inclination is not good, there are bubbles between the tin liquid and the PCB, and the bubble bursts to produce tin beads.
  • Improper operation method when the hand is soaked in tin.
  • Wet working environment.
Problem with PCB board
  • The board surface is wet, not fully preheated, or moisture is produced.
  • The hole design of PCB running gas is unreasonable, causing air to be trapped between the PCB and the solder.
  • The PCB design is unreasonable, and the parts are too dense, causing air.
Short circuit
Short circuit caused by tin solution.
  • Continuous welding occurred but not detected.
  • The tin solution does not reach the normal working temperature, and there is a "ting wire" bridge between the solder joints.
  • There is a slight tin bead bridge between the solder joints.
  • Continuous welding is the bridge.
PCB problems:
The solder mask of the PCB itself falls off, resulting in a short circuit.
