Cooling System | |
Refrigeration method | The cool air temperature at the outlet of forced air cooling can reach below 50℃ by using axial flow fan, which can obviously improve the problems of vacuole and disc stripping during the formation of lead-free solder eutectic. The base plate is cooled sharply to ensure the crystallization effect of the solder joint. The cooling air exhaust pipe is added with insulation layer, and there is no cooling water drop outside the pipe!) |
