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

is that fan speed program controlled or manually?

I'm not familiar with the HVN70 programming but our conceptronic oven reacts well to adjusting the cooling fan speed at the end of the oven. However, TAL will likely be affected substantially by changing fan speed.

Dave, For lead free, I've always left the ramp part the same and just spike higher in the reflow zone. I've also slowed things down a bit (5" per sec. slower)....without using prediction software, try, say... Z4 200 & Z5 260.

starting point with zone settings would be, 100 / 160 / 200 / 225 / 260 deg C...but you'll have to check the exact profile on the pcb with a reflow profiler....making sure you meet the paste spec and making sure you don't heat any devices up to quic

Hi, We have a 5 zone oven and we use a RTS Profile. Our last zone is the zone that the reflow takes place. some basic analysis is as follows: TAL 70 secs, peak temp 210,ramp rate seems fine. A typical setting is : Z1 140 Z2 160 Z3 160 Z4 185 Z5 220

Thanks This error only occurred with one oven profile with the reflow zone temperature set at 270�C. Perhaps it really has to do with the exhaust pull as the oven is operating very near its temperature limit with this profile. I will check that. Tha

we are using alphametals no clean 95sn/5ag CL775 paste. After reflow there are solder balls on the board. mainly are around the cap. We are using a conceptronic concept 60 air. There are 4 zones with 8 chambers. We are not sure what the profile
