Can anyone tell me what the recommended "typical" cooling rates are after reflow? Are the cooling rates considered as critical to control as the heating rates and why/why not?

All, I would like to find out if it is possible to adjust the cooling rate on a Conceptronic Reflow Oven Model HVN70. We do not use Nitrogen and the Cooloing system is Genesis GCM-1. From profiling it seems to be cooling too quickly. Any replies a

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

No delta T issues as I am not actually reflowing the component to the PCB. This is for moisture sensitivity testing as per JEDEC 020C Standard. Trying to duplicate a profile in the standard and am having trouble reaching a component ramp rate of 3

Who's controlling the cooling rate when profiling? If so, what's the max cooling rate you're trying to hold?

There are two areas that are important when discussing cooling rate. One is the rate thru the liquidus, where a fast rate produces small grains in the metal and a slow rate results in larger grains. Although smaller grains are stronger normal SM

This is the first time I heard that the heating and cooling rates should be identical so I downloaded a copy of the paper to see what it said. There is one short paragraph claiming that the rates should be equal but no references or data. This doesn'
