100% Power on cooling fans. Cooling fan speed can be adjusted, but convection fans can�t.

Hello Phil, As the other respondents have mentioned, the cooling rate is not easily controlled and varies based on the oven and board design, as well as the settings of the last few zones and cooling zones. In general, the board is going to cool in

One of the reasons for a grainy joint is the cooling of the joint after reflow. Check your reflow profile, not just the preheating and reflow section but also the cooling zones. It works the same way as molten rock. If it cools slowly you get pumice

Hi , The 4th stage in reflow soldering, the cool-down, I find is often over looked. A rapid cooling rate should give finer lead and tin structure with more bindings and thereby result in stronger solder joints. Can anybody give me some information

Should be too high temperature on somewehere on machine, 1 Check cooling oil tank, If the cooling oil need replaced? Check the radiator of cooling tank, withdraw the filtering net and clean it,and clean the dust off the radiator of cooling tank wi

All, I have a Conceptronic HVN70 reflow oven with Genesis Cooling System. After profiling and checking the readings, the Cooling Rate seems to be very fast. Does anyone know if the cooling is adjustable? aj

With high volume production, this can happen. The flux is vaporizing in the heating zones, and is condensing in the cooling zones. Depending on the machine, cooling can act differently on different machines. Less cooling may reduce this problem.

Thanks. I will turn off the machine activated cooling and have the part cool down at room temp (no compressed air cooling). Can you recommend a good paste / tacky flux?
