I'm assuming the ramp up and the very fast ramp down (1.5 minutes from 250 to 75) in temperature is good? BTW that display reminds me of something from the 80's, very large pixels...
Yep, the thermal ramp times are decent, we need to follow a certain profile for each type of solder paste / PCB.
One function of the hacked software upgrade is to run the cooling fans during the reflow process to help even out internal hotspots... running these fans effects the thermal ramp-up speed, we cannot have too much circulation / ventilation during the heating phase.... Mickey Mouse games...
The larger oven simply lacked the thermal and cooling power to follow the require curves!
The Pro reflow oven I plan to purchase once funds allow is controlled via a PC so yep, that display will not be missed
