It looks like the 330 Convection & the GF120 ovens would really stuggle to do lead free, with 3 zones (the 330 has 3 top, 1 bottom). Can't comment on the 545 oven, you'll have to get them to run profiles with a selection of your boards & check on

We've been down this road before, and it doesn't have to be as expensive as it would seem. First, ask your board supplier for a solder sample of the board. They are likely to have a scrap board that you can use for your profiling. As for the BGA(s

I ran a profile on a dummy board with no parts and the peak temp is 220. The 220 is just the temperature of the board of course. With that BGA on it, I am pretty sure it sucks up alot of the heat. Also I am looking at the profile and notice that i

I face a problem where the components termination is non lead free but solder alloy is lead free. Thus i am using hybrid reflow profile. The specs for the reflow profile i am using: reflow temp. 120 to 160 deg C; time 90 to 120 sec. As for the pak te

We do something quite simple that may or may not be adequate but I cannot think of why it would not be adequate. If anybody can please inform. We have a large board about the samer width as our oven. We have dedicated thermocouples on this board a

All data loggers will be warmer at the higher lead free temps. Only two ways around this... better thermal barriers or fans after the profile to cool it down. Some places do not allow fans on the production floor due to static electricity, in that

I used 1' of McMaster part # 8821K6 (0.110" thick). It is rated to 600F. I believe I put four layers over my profiler but I'd recommend starting with two. If you need more you can add it. Make the sock good and tight because the fabric seems to h

Well, a "reflothermal recipe" is a typo. It should read "reflow thermal recipe". Sorry for the confusion. Most people call this THE PROFILE. We think a profile is the output of a profiler when it portrays the result of a reflow recipe. We're gue

This is a used oven, new to us. No product has been setup on it yet. We were establishing som baseline profiles and noticed that the actual profile read didn't even come close to our optimal profile. Further investigation proved that the belt was to

I have this board that we are currently having problems with. When we run the BGA side with the hotter temp. the connectors on the other side lift off their pads. The BGA is lead free, that is why we have to use the hotter profile. Would it be
