Attention of reflow soldering

1.The reflow soldering furnace must reach the set temperature (green light) , in order to start welding

2.the development of the work requires us to be able to observe the temperature changes in various temperature zones, cross-range 1C (according to the reflow soldering furnace) .

3.when the equipment management problems, should be stopped immediately.

4.the size of the substrate can not be large conveyor belt width, otherwise prone to card board accident.

5.Before welding, take protective measures (shield) or do not reflow soldering for components that can not stand the normal welding temperature according to the processing documents of the patch or the package instructions of the components, and use manual soldering, or welding robot after welding.

6.welding technology in the process of research to prevent the conveyor belt from the impact of vibration, otherwise it will be easy to cause component displacement

7.Time analysis and measurement of the reflow furnace exhaust fan body application: reflow soldering applications are very wide. Now many electronic products are in the development of integration, most of the circuit boards are used in the SMT process, so in the use of SMT process must use reflow soldering. Such as electrical and electronic products, military products and so on.
