Thanks for your thoughts. So it seems then that the temperatures that we're seeing aren't unusual, and just need to sort out the fan issue... @Sr. Tech: Yeah, totally understand the radiator effect. Once the fan issue is sorted, we plan on insulatin

Our Heller oven is functioning well. However, we see defects from the oven, such as shifted coil inductor components, and missing chip components from time to time. When we re-scan the board at the AOI, the defect was not present at that stage,hence

Hi all. We recently expanded our assembly space and moved our Heller 1500 oven to a new spot. In the old arrangement, we used a Purex filtration unit, keeping the hot air in our space. Recirculating the fumes caused a massive headache in cooling the

slowing-down the conveyor to allow the solder to heat these balls more. But that may not be the answer, because if the flux is exhausted, more heat will not help. Then if the flux is exhausted, the answer is to crank the belt. Two different answer

thanks for your replies, I will check about oven integrity (calibration) and any exhaust issue... as fas as I know there's not change or addition to exhaust system but I need to confirm.

Thank you for the information. I have 1 more thing to ask, Venting: Three 4” (102mm) dia. flanges 200 CFM (340m3/h) ea. What thus three 4" specify? Is it the number of exhaust ventilation? and 200 CFM could be the specs per exhaust?

We are currently experiencing with our SMD Solder Reflow Equipment on Shooting-Up Zones (Zones 3,4,5,7 & even Cooling Zone). PV exceeds about 5-10 degrees with the SP. (ex: SP=140deg, actual PV = 145deg & higher). Our equipment undergo a monthly prev

Hi. There is no problem with the exhaust system and the owen also has a sensor to messure the exhaust and would give an alarm if it stopped or went under a preset value. We have had our owens for one year now and the problem just started suddenly, we
